SHELL POLYGROUT (PC 2136) is a low viscosity liquid which react with water in a controlled manner to form a swelling resilient adhesive solid in densities and strength appropriate to the designated task. When impregnated under pressure into leaking structures, through the process of polymerization, a permanent flexible/rigid water barrier is formed. The liquid retains its initial low viscosity upon contacting water allowing it to flow without dilution. Once the SHELL POLYGROUT water reaction commences, the grout expands penetrating into its surrounding and quickly cures to a tough, adhesive solid to repel the influence of underground seepage flow and solidify the objective ground which is unaffected by corrosive environments.
AREA OF APPLICATION :
