AkvaVIS S400 — elastic polyurethane injection resin
Low-viscosity resin for sealing dry and damp cracks and joints in reinforced concrete and cut-off waterproofing of masonry; penetrates cracks from 0.2 mm.

A gel, not a foam: AkvaVIS G is a one-component elastic hydroactive solvent-free polyurethane compound that does not shrink in a water-saturated environment and reversibly changes volume as the water level fluctuates. It is injected into cracks, cold and expansion joints of reinforced concrete and service penetrations, and is used for cut-off waterproofing, anti-seepage curtains in the soil behind structures and consolidation of loose soils. The highly elastic gel withstands dynamic loads; work is carried out at temperatures above +5 °C.
| Manufacturer | AkvaVIS — OOO “GELIOS” |
|---|---|
| Type | injection waterproofing |
| Use | foundations and basements, tunnels and metro, tanks and pools, joints and junctions, leak repair |
| Base | one-component elastic hydroactive polyurethane injection gel, solvent-free |
| Packaging | pails, canisters of 10, 20, 25, 60 kg |
| Application method | with active water ingress, first stop the leak with a plugging compound; drill holes to 2/3–3/4 of the structure thickness at 30–45°, 20–25 cm spacing in a staggered pattern; Ø10 mm metal packers; one-component piston pump; pre-wet a dry substrate with water; after polymerisation remove the packers and plug the holes |
| Application temperature | above +5 °C |
| Curing | gel time 190±60 s |
| Key properties | viscosity without water 800–1000 mPa·s, with water 1 : 10 — 3–50 mPa·s (20 °C); density 1.12±0.03 g/cm³; highly elastic gel, withstands dynamic loads; non-shrinking in a water-saturated environment, the volume change with fluctuating water level is reversible |
