 Real estate

Real estate investments will invariably retain their functional, monetary and prestige value for investors, owners and users,
provided that the properties in question are maintained. Nowadays, damp walls, cracked ceilings and unstable floors can be
permanently repaired using minimally invasive injection measures, protecting and strengthening a building before such defects
can cause major damage. Occasionally, injections are also required to introduce subsequent waterproofing under floor slabs or
at other locations which cannot be reached from the outside. MC’s injection systems offer all the technological prerequisites to
enable such work to be carried out successfully.

Your tasks:
n Protection of the concrete against ingress of water and
other harmful substances through cracks and cavities

n Reinforcement of concrete components in the area

of cracks and cavities to better resist tensile and
compressive loading

n Corrosion protection of the reinforcing steel and

similar inserts

n Waterproofing of external components, particularly in

areas in contact with subsoil

n Sealing of construction and expansion joints

Your solutions:
MC-Injekt 2300 top/2300 rapid elastomer resins will prevent ingress of water or other harmful substances likely to impair the
durability and utility value of reinforced concrete in real estate properties. The structural integrity of reinforced and prestressed
concrete components under conditions of tensile and compressive loading can be reinstated through injection of rigid-setting
MC-Injekt 126 compact. Larger cavities are permanently reinforced with Centricrete HCS. Meanwhile, MC-Injekt 3000 HPS, a
flexible and swellable hydrostructural resin, can be used for both waterproofing structures in contact with the ground and the
subsequent sealing of the adjacent subsoil. And MC-Injekt GL-95 TX has proven to be particularly effective in the repair-sealing of
leaky movement joints in structures that are in contact with the ground.

 Multi-storey and
underground car parks

Multi-storey and underground car parks are exposed to particular forms of degradation. In contrast to other buildings, they need
to withstand dynamic loads, adverse weather conditions and de-icing agents as a matter of course. Any form of cracking is
particularly critical. Penetrating water restricts the usability and safety of car parks. However, this and major consequential
damage to the building fabric can be avoided through the use of injection systems.

Your tasks:
n Protection of the concrete against the ingress of
harmful substances through cracks and cavities

n Reinforcement of concrete components to withstand

tensile and compressive loading

n Corrosion protection of reinforcing steel and

similar inserts

n Waterproofing of external components, particularly in

areas in contact with the subsoil

n Sealing of construction and expansion joints

n Improvement of components prior to surface coating

and/or installation of adhesive-bonded CFRP strips etc.

Your solutions:
MC-Injekt 2300 top/2300 rapid elastomer resins prevent the penetration of contaminants in reinforced concrete for effective
corrosion protection, thus eliminating the danger of water impairing the durability and usability of multi-storey and underground
car parks. Where reinforced and pre-stressed concrete components are exposed to tensile and compressive loading, rigid-setting
MC-Injekt 1264 compact can be injected to reinstate stability and durability. Major voids and cavities are efficiently reinforced
and sealed with Centricrete HCS, while the flexible and swellable MC-Injekt 3000 HPS hydrostructural resin can be used for both
waterproofing concrete components in contact with the ground and the subsequent sealing of the adjacent subsoil. And hydro-
structural resin MC-Injekt GL-95 TX has proven to be particularly effective in the subsequent sealing of leaky movement joints in
structures in contact with the ground.

5
 Industrial buildings

Floors in industrial buildings – including warehouses and material handling concourses – have to be built to withstand not just
static and dynamic loads but also, in many cases, chemical attack. Such highly stressed concrete surfaces need to be densely
compacted, waterproof, homogeneous and flat. Permanent, effective concrete repairs start with the sealing or rigid filling of
cracks and cavities. And should you also require a solution for foundation soil rehabilitation, MC offers a range of speciality
products in its MC-Montan Injekt range of injection systems.

Your tasks:
n Protection of the concrete against the ingress of
harmful substances through cracks and cavities

n Prevention of liquid ingress and leaks

n Corrosion protection of the reinforcing steel

n Rigid filling of cracks and cavities resistant to

compressive and tensile forces

n Pressure-grouting of traffic-carrying surfaces for

the purpose of stabilisation and levelling

Your solutions:
Rigid-setting MC-Injekt 1264 compact is an effective injection sealant for strengthening concrete and reinforced concrete
components under conditions of tensile and compressive loading, ensuring that the reinforcing steel and similar inserts are firmly
bonded to the concrete matrix. This duromer resin even cures under dynamic load cycling and is non-susceptible to moisture.
MC-Injekt 2300 top/2300 rapid elastomer resins are injected to provide flexible protection against the penetration of contaminants
through cracks and cavities, while rigid cracks and cavities in concrete can be effectively repaired by injecting Centricrete HCS
with its concrete-like properties.

6
 Bridges

Whether made of prestressed concrete, reinforced concrete, rammed concrete or masonry, bridges are vital to the transport
infrastructure. However, with increasing traffic volumes, higher axle loads and consistently aggressive environmental influences,
they are under increasing strain. Injection systems offer innovative and effective solutions for the protection, maintenance, repair
and reinforcement of bridges.

Your tasks:
n Protection of the concrete against the ingress of
harmful substances through cracks and cavities

n Tensile strengthening of cracked reinforced concrete

n Compressive reinforcement of concrete prone to

high levels of cavitation

n Corrosion protection of the reinforcing steel

n Repair and upgrade of components prior to surface

coating or the adhesive bonding of CFRP strips

Your solutions:
Rigid-setting MC-Injekt 1264 compact serves as an effective injection sealant for components of reinforced and prestressed
concrete under conditions of tensile and compressive loading. The low-viscous duromer resin produces the required injection
results even under the influence of dynamic load cycling. Major cavities are permanently reinforced with Centricrete HCS, a
mineral suspension that possesses the special properties required to improve and reinforce concrete and natural rock. For the
flexible sealing of cracks, the outstanding injection properties of MC-Injekt 2300 top/2300 rapid make these elastomer resins a
particularly effective solution. MC-Injekt 3000 HPS can be used to counter and prevent any wide-area dampness in concrete or
masonry bridge structures in contact with the earth, and can also be employed for subsequent sealing work on the adjoining
subsoil.

7
 Potable water structures

Drinking water is our most vital resource and must be protected from contamination during processing, transport and storage.
While the lining of facilities, piping and containers must meet certain functional requirements relating to stability and imper-
meability, so too must the materials of the buildings that house them. There are also water-hygiene requirements that need to be
met by repair systems. This is where speciality injection resins can have a significant beneficial impact.

Your tasks:
n Protection of the concrete against the ingress of
harmful substances through cracks and cavities

n Waterproofing of the building structure against

infiltration and exfiltration

n Sealing of cracks and cavities in order to create smooth,

hygienically sound surfaces that are easy to clean

n Filling of cracks, flaws and cavities in

structural concrete

Your solutions:
Classic sealing and injection tasks involving the filling of cracks and cavities are reliably carried out with high-performance
MC-Injekt 2300 top/2300 rapid elastomer resins. Verified as hygienically harmless, these highly flexible reaction products are well
suited to applications in potable water systems. MC-Injekt 3000 HPS hydrostructural resin carries similar hygiene credentials
while offering elasticity and swelling properties that are ideal in constructions permanently exposed to water contact. Sub-
sequent sealing of the adjacent subsoil can also be carried out with MC-Injekt 3000 HPS. Larger cavities are efficiently filled with
the mineral suspension Centricrete HCS serving to strengthen and upgrade the structure. If geotechnical injection work is
required, resins from the MC-Montan Injekt series are highly recommended.

8
 Sewerage structures

Despite being exposed to high mechanical loading and chemical attack, the structures and ducting used for the collection and
disposal of wastewater, effluent and sewage are required to exhibit exceptionally long service lifetimes. Regular maintenance and
repair measures must take into account the high physical and chemical attrition to which both the original network components
and the repair products are exposed. MC offers a selection of speciality solutions in the form of its MC-Montan Injekt range of
injection systems tailored to meeting the particular requirements encountered in subterranean infrastructure.

Your tasks:
n Waterproofing of structures against infiltration
and exfiltration

n Elimination of manufacturing defects such as cracks,

voids and cavities in the concrete and masonry

n Embedding of injection hoses in

critical construction joints

n Reinforcement of the construction

Your solutions:
Classic sealing injection tasks involving the filling of cracks and cavities can be reliably executed using high-performance
MC-Injekt 2300 top/2300 rapid elastomer resins. These exceptionally flexible reaction products are chemically resistant and
environmentally compatible. Larger cavities can be efficiently filled with the mineral suspension Centricrete HCS to strengthen the
construction. Impressive in terms of its moisture tolerance, chemical resistance and durability as a rigid-setting crack and cavity
filler, MC-Injekt 1264 compact duromer resin offers even higher strengths with faster curing. The adjacent subsoil can be
subsequently sealed with MC-Injekt 3000 HPS. More extensive geotechnical injection work requires use of resins from the
MC-Montan Injekt series.

9
 Subterranean infrastructure

Subterranean infrastructure performs a wide range of functions, providing essential lifelines for efficient, comfortable urban
existence. Media channels serve to enhance the ease and convenience with which we pursue our lives. However, because they
are invariably embedded in foundation soil and building developments, their maintenance and repair are particularly complicated
and expensive. Subterranean ducting can often only be strengthened and sealed from the inside using injection techniques.
Minimally invasive injection technologies reduce the cost of application without disrupting municipal life. The MC-Montan Injekt
range of injection systems offer a range of speciality products for the unique applications encountered in underground networks.

Your tasks:
n Protection and waterproofing of manholes and
shaft structures

n Sealing of joints, cracks and cavities in ducting and

sewerage to prevent infiltration and exfiltration

n Sealing of pipe transits

n External waterproofing through curtain injection

n Backfilling and consolidation of foundation soil

Your solutions:
Cavities in sewerage structures can be effectively filled with the Centricrete HCS mineral suspension, which also serves
to strengthen the construction. MC-Injekt 1264 compact offers more rapid strength development. This duromer resin is also
particularly impressive in terms of its moisture compatibility, chemical resistance and durability, with its rigid-setting and sealing
action enabling the effective filling of cracks and cavities. Meanwhile, MC-Injekt 2300 top/2300 rapid elastomer resin sealants are
ideal when it comes to preventing water and contaminant penetration. The adjacent subsoil can be subsequently sealed using
MC-Injekt 3000 HPS, and for geotechnical injections, the resins of the MC-Montan Injekt range offer proven performance.

10
 Hydraulic structures

Hydraulic structures are important for energy production, drinking water supply, waterway navigation and regulation of the
ecological water balance, making them integral to public life, industry and the environment. Like the adjacent rock and soil, the
concrete or masonry construction materials must meet special requirements in terms of stability and water impermeability.
Injection systems are often the best solution when it comes to ensuring the protection, reinforcement and sealing of these
structures. MC offers a range of specialised products for the unique requirements encountered in the massive constructions and
geotechnical work involved in such projects. Take a look at our MC-Montan Injekt range of systems.

Your tasks:
n Stabilisation and reinforcement of the construction

n Ensuring water impermeability in line with specifications

n Sealing of joints and surfaces against pressurised and

non-pressurised water

n Grouting and backfilling of voids and cavities

n Sealing and consolidation of adjacent subsoil and rock

Your solutions:
Ensuring water impermeability is often beset with problems, most of which can be successfully solved using MC-Injekt 2300 top /
2300 rapid elastomer resins. MC-Injekt 2133 flex offers a superior alternative for the injection of cracks and joints in the con-
struction. MC-Injekt GL-95 TX hydrostructural resin has proven extremely successful in the sealing of movement joints, while
irregularities, inhomogeneities and cavities in the concrete or natural stone can be efficiently back-filled with Centricrete HCS to
reinforce the construction. For geotechnical injection work, the MC-Montan Injekt range offers products of proven performance.

11
 Tunnels

Tunnel building is one of the most demanding engineering disciplines in the construction industry. Tunnel structures have to meet
extremely high standards in terms of their strength, water impermeability and durability. With the process always susceptible to
the interaction between manmade building, natural rock and water, injection measures are invariably a necessary part of the
construction project. MC offers a complete product portfolio for the special tasks encountered in tunnel construction. For further
information on this subject, please ask for our separate tunnelling brochure.

Your tasks:
n To support, safeguard and waterproof start and
end shafts, as well as the shield tail when carrying out
maintenance measures to prevent unwanted water
ingress

n Advanced stabilising and waterproofing injection in

order to secure the freshly excavated tunnel tube

n Shield tail sealing for maintenance work as tunnel

boring continues

n Protection of the concrete against the penetration of

contaminants via cracks and cavities

n Waterproofing and subsequent sealing of tubbing joints

Your solutions:
An injected annular seal made of MC-Montan Injekt TR-X secures the transition area between the tunnel boring machine and
the subsoil. MC-Montan Injekt TR-X can also seal the tunnel tube as heading proceeds, providing stability in critical areas
where the rock is loose, for example when the shield tail seal has to be replaced. The hydrostructural resin is also used in tunnel
construction to subsequently seal surfaces and movement joints between the tunnel segments. Injections into cracks in concrete
components are best carried out using MC-Injekt 2300 top/2300 rapid elastomer resin sealants. For rigid and reinforcing seals,
MC-Injekt 1264 compact is an ideal option. Under certain circumstances, MC-Injekt 2133 flex may also contribute to ensuring that
cracks and joints are durably sealed. For geotechnical injections, resins of the MC-Montan Injekt range are particularly effective.

12
 Concrete bearing surfaces

Concreted trafficable surfaces are essential for the transport, storage and trans-shipment of goods on roads, in ports, on airfields
and on all the adjacent logistics and handling areas. Specialised injection systems serve to successfully stabilise concrete slabs
through consolidation of the subsoil while lifting and levelling where required.

Your tasks:
n Grouting and stabilisation of concrete slabs

n Consolidation of the subsoil

n Grouting of cavities, crevices, gaps and voids

n Raising and levelling concrete slabs

n Protection against erosion and other

undermining phenomena

Your solutions:
Solid and reliable, MC-Montan Injekt resins are ideal for the consolidation or raising of components and ensuring that they are
externally sealed. The resins available offer a tailorable spectrum of performance features such as strength development,
modulus of deformation and reactive expansion. MC-Montan Injekt FF, with reactive expansion and a defined level of strength, is
an efficient solution for stabilising and securing the position of concrete slabs. MC-Montan Injekt CB is a mineral-organic hybrid
system that offers enhanced fire protection and cures even in the presence of moisture and water. With both resins, floor
slabs can also be raised and levelled with accuracy by metering the injection process. With selectable reaction times, the
MC-Montan Injekt FR/FN/FS range is ideally suited to filling gaps and penetrating crevices and voids in the loose rock or sub-
soil. The resin systems of the MC-Montan Injekt series are further characterised by their proven environmental compatibility.

13
 Ballast beds

Regional and super-regional railways form the backbone of essential infrastructure serving commerce, industry and the public at
large. Quality in railways is essentially determined by the standard of track engineering. Ballast bonding systems can contribute
to reducing construction and reconstruction costs. They offer increased operational reliability and safety, coupled with reduced
vehicle wear and tear. Embankments and rocky areas can also benefit from the provision of secured, bonded gravel surfaces.

Your tasks:
n Bonding, stabilisation and retention of loose rock

n Bonding, stabilisation and retention of ballast-mounted

track superstructure components required to withstand
rapid loading

n Waterproofing of gravel surfaces

n Blending of the ballast bed in transitions between

earthworks and manmade structures

n Securing ballast beds during track construction work

n Environmentally compatible, permanent vegetation

growth restriction

Your solutions:
There are three resin systems available for bonding, stabilising and retaining loose rock. MC-Ballastbond 70 offers the widest
performance range. This resin system penetrates into the ballast bed and bonds the gravel at the contact points, delivering a rapid
increase in strength without impairing drainage capacity. MC-Ballastbond 70 is also particularly environmentally compatible.
MC-Ballastbond 80 is a mineral-organic hybrid system that is unaffected by moisture or water as it reacts, offering a higher level
of fire safety coupled with lower strength levels. And MC-Ballastbond 60/60 SC is a transparent duromer resin system capable of
achieving very high strength values.

14
 Excavation pits and
foundation soil

Without subsoil, there can be no building. Structural stability depends on having foundation soil of sufficient bearing capacity
despite differing strata, compositions and varying water interference. Water penetrating into the excavation pit, and loose rock
slipping down trench walls can considerably disrupt the construction process. MC injection systems ensure safe and secure
building conditions and reliable construction scheduling. If the foundation of a building has to be corrected even long after its
completion, consolidating, reinforcing and lifting injection technologies can be reliably deployed to resolve the issue.

Your tasks:
n Consolidation and securing of excavation pit surrounds

n Prevention of inflowing water

n Filling of crevices, cavities, voids and gaps

n Reinforcement and sealing of subsoil

n Lifting injections

Your solutions:
Quick-setting resins are required to seal the surrounding subsoil and thus secure excavation pits. MC-Montan Injekt injection
resins offer easy injectability and variable reaction times, with reactive expansion just one of the options available. The
MC-Montan Injekt FR/FN/FS range is universally applicable for the stabilisation and retention of excavation envelopes. It can
be adjusted to a broad array of different application conditions. MC-Montan Injekt CB is a mineral-organic hybrid system that is
unaffected by moisture and water as it reacts. This resin can be injected into subsoil that has to be penetrated later by an
excavator or some other machine. MC-Montan Injekt DR/DS offers outstanding injectability and binding forces for effective
flexible sealing.

 Application techniques
for the filling, grouting and sealing
of subsoil, joints, cracks, crevices,
cavities and voids
Component filling from the surface
Dry and moderately damp cracks in components can be filled from the surface. This has to be prepared and then provided with
appropriate packers to enable the injection work to be carried out. The injection packers are bonded into place at intervals
corresponding to the depth of the crack (up to max. 60 cm). The cracked surface needs to be sealed. Cracks that are accessible
from both faces need to be sealed on both faces. From depths of 60 cm, these may again be provided with adhesion packers in
order to optimise the level of fill. On surfaces that are horizontal or only slightly inclined, cracks can be simply filled under gravity.
To ensure a continuous material flow, a cut should be made along the line of the crack for feeding in the injection compound.
Further information is available in the form of instructions relating to each specific injection material.

Adhesion packers: These are bonded onto the component Gravitational filling: Gravitational filling is performed under
surface at intervals corresponding to the crack depth (with pressureless conditions (and without packers). Wide cracks

will need to be ground out first.

Filling of components through drilled channels

Damp, moist and water-bearing cracks and cavities in components can be filled via channels drilled at a certain angle crossing
the crack or cavity. The intervals between the drilled channels should correspond to half the crack depth (up to a maximum of
60 cm). Further information is available in the instructions relating to the relevant injection compound.

Borepacker drill hole packers: These are inserted in the Borepacker drill hole packers: Shown inserted in drilled
drilled holes at a distance corresponding to half the crack holes (usually without surface sealant).
depth in a staggered formation on both sides of the crack
(usually without surface sealant).

24
Joint injection
Water-bearing construction joints or expansion joints can be filled via drilled channels or injection hoses. For injection via
drilled channels, the holes required are made at a certain inclined angle crossing the joint or at 90° through the rear material. The
intervals in the case of construction joints should correspond to half the component thickness (up to max. 60 cm). Significantly
larger packer intervals are possible in the case of expansion joint injection work, depending on the flow path configuration.
For further information, please consult the application instructions relating to the injection material used.

angle of 30–45° to access the joint. Techniques
Hose injection at construction joints. For solutions with no joint strip contact, see “Subsequent
interface sealing” below.

Subsequent interface sealing

Damp components may be subsequently sealed from the outside (curtain injection) or through provision of a barrier membrane
