CFT Harz

CFT Harz is an instantly setting three component injection resin, CFC- and halogen-free.

CFT Harz, component A is a mixture of various polyols and additives. CFT Harz, component B is a polyisocyanate. CFT Harz, component C is an accelerator.

The mixed resin penetrates the structure which has to be sealed. The majority of any water in there is displaced due to the hydrophobic nature and the viscosity of the resin. Traces of water make the resin foam.

This resin is designed for sealing, stabilisation and consolidation in water-bearing strata and repair of old sewers, shafts, and tunnels.

CarboStop

Special types with closed-cell resin structure were developed to increase ground impermeability or seal joints in civil structures.

These products are used for:

Grouting of fine to very fine hair line cracks and water-carrying sands or porous materials. Used for deep injecting, fixing of anchors, stabilisation and sealing of loose rock, stoppage of water inflow (also salt water), injecting of man-accessible sewer lines and tubes.

Stopping water inflow (also salt water), stabilisation and water sealing of loose rock, grouting of fine to medium-fine grained sands and gravel, fixing of anchors, injection of cracks, honeycombs, injections of man-accessible sewer lines and tubes

Stopping of water inflow (also salt water), sealing of loose rock, sealing of cracks and expansion joints in bridges and concrete structures. For use in deep injection, grouting of medium-fine to larger cracks, fissures, honeycombs, injections of man-accessible sewer lines and tubes where high elasticity and flexibility is required.

Stopping of flowing water, restoration of concrete structures according to German ZTV-ING.

CarboPur

These resins are applicable over a wide range of temperatures and act effectively even against pressurised water.

CarboPur resins production line offers high-quality materials for temporary or permanent applications with different reaction data and resin behavior, applicable in infrastructure and civil engineering.

CarboPur WX is used for stabilisation in wet or water bearing rock formations. It is used for sealing water tributaries from rock formations, dams, or shaft walls. It can be used in renovation of wet shafts, tunnels, sewers, or brickwork.

CarboPur WF is used for sealing against water under hydrostatic pressure from strata, dams or shaft walls, sealing and consolidation in water-bearing strata and against water under pressure.

CarboPur WS is used for curtain injection in tunnels, dams, or on shaft walls; sealing against water, stabilisation, consolidation and repairing of cracks &/or fissures.

CarboPur WFA is used for sealing strong water ingress, e.g.construction pits, pipelines, shafts, and tunnels.

CarboPur WT is used in sealing against water under hydrostatic pressure from strata, dams or shaft walls, repair of wet shafts, tunnels, channels and walls, sealing of under water concrete sheet pilings and diaphragm walls.
