WETISOL I-5020 — injection resin with rigid foam
Wetisol (INGRI)

WETISOL I-5020 — injection resin with rigid foam

Injection waterproofing

On entering water, WETISOL I-5020 foams and hardens, forming a rigid foam. The solvent-free resin is designed to stop pressurised water, including sea water, at pressures of up to 0.5 atm, to pre-seal water-bearing cracks, fill voids and bind soil. Foaming starts after 7–13 s, the foam rises in 70–90 s, and the reaction rate is controlled by the catalyst. After the leak is stopped, the crack is sealed with WETISOL I-5106 LV.
