CarboPur WS

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

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.

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.


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).
