CarboPur WFA

CarboPur WFA is an extremely fast reacting, dual-component, polyurethane injection resin for permanent consolidation and sealing of strata even in damp, water-bearing strata.

CarboPur WFA was developed for application in mining, tunnelling, civil engineering and reconstruction of buildings.

CarboPur WFA is used for:

  • Consolidation in dry,wet and water-bearing strata
  • Sealing against strong water ingress (also seawater)
  • Sealing against water under pressure e.g. from strata, dams or shaft walls
  • Stabilization and sealing work in tunnels
  • Repair of old shafts and tunnels
  • Stabilization of crown abutments in tunnelling
  • Sealing of anchoring of sheet pilings etc. in ground water and many other special applications

CarboPur WS

CarboPur WS, as a sealing material it is compatible with ground water causing no negative effect. No significant changes are detectable if and when coming in contact with tunnel sealing bands.

System
The mixed resin penetrates the structure to be sealed. The water in the cracks and joints is displaced due to the resins hydrophobic nature and viscosity.

Components

CarboPur WS, Component A is a mixture of various polyols and additives.
CarboPur WS, component B is a polyisocyanate.

Final product
When the final mix comes into contact with water, the resin foams up in different volumes,thus the mechanical properties vary accordingly. The cured resin is resistant against many acids, alkali and salt brines as well as organic solvents (if in doubt consult Minova representative).

​CarboLith PL

WHY CARBOLITH PL?

CarboLith PL is used to repair sewer ducts and pipes and features excellent properties and economical advantages. The non-foaming elasticised resin hardens very well even in case of large volumes of external water inflow.

Component A of Carbolith PL is a water-glass component with additives. Component B is a modified polyisocyanate. Component C is a blend of additives improving the components and regulating the pot life of the mixture.The combination of components and liner forms an interpenetrating network of tough elastic, non-foamed silicate resin.
