AkvaVIS G — elastic polyurethane injection gel
Hydroactive polyurethane gel for injecting cracks, cold and expansion joints and anti-seepage curtains in soil; gels in 190±60 s.

Dual purpose sets AkvaVIS S402 apart: on its own the compound works as a one-component foam that expands 10–15 times on contact with water, and mixed with component A at 100 : 100 by mass it becomes an elastic resin with a viscosity of 70–100 mPa·s. The system is used to eliminate water inflow, seal joints and cracks, construct and repair expansion joints, fill voids and consolidate soils behind tunnel linings. The resin remains elastic at sub-zero temperatures, and its pot life is 60 min. Kit A+B — 40 kg.
| Manufacturer | AkvaVIS — OOO “GELIOS” |
|---|---|
| Type | injection waterproofing |
| Use | foundations and basements, tunnels and metro, tanks and pools, joints and junctions, leak repair |
| Base | two-component polyurethane injection system: AkvaVIS S402 — one-component foam; with component A — elastic resin |
| Packaging | 20 + 20 kg, kit (A+B) 40 kg |
| Application method | foam — with a one-component pump; resin — mixing S402 with component A 100 : 100 by mass (0.91 : 1 by volume) with a mixer at 300 rpm for at least 3 min; for expansion joints an activator can be added and a two-component pump used; use opened packaging within 24 h; material temperature preferably +15…+25 °C |
