AkvaVIS S400 — elastic polyurethane injection resin
AkvaVIS S400 resin is a two-component elastic polyurethane of very low viscosity without solvents: a mix viscosity of 150 mPa·s allows it to penetrate cracks from 0.2 mm. It is used to seal dry and damp cracks, joints and seams in reinforced concrete, and to create cut-off waterproofing against capillary moisture in brick and stone walls. On contact with water its volume hardly increases, the cured compound does not become brittle, and the glass transition temperature is −35 °C. Active leaks are first stopped with AkvaVIS P foam before injection.
Specifications
| Manufacturer | AkvaVIS — OOO “GELIOS” |
|---|---|
| Type | injection waterproofing |
| Use | foundations and basements, tanks and pools, joints and junctions, leak repair |
| Base | two-component elastic polyurethane injection resin of very low viscosity, solvent-free |
| Application method | first stop active leaks with AkvaVIS P foam or plugging compounds; caulk the cracks with a polymer-cement compound; mix A and B 1 : 1 by volume (100 : 106 by mass) with a low-speed mixer for at least 3 min; holes are drilled at an angle of 30–45° crossing the crack/joint, packer spacing 20–25 cm, often in a staggered pattern; clean the holes with compressed air or water; Ø10 mm packers; one-component piston pump; increase the injection pressure gradually, not above Pmax = 10 atm × concrete class / 3 (for B45 — not more than 150 atm); inject from bottom to top until completely filled (checked at the adjacent packer); after polymerisation remove the packers, plug the holes with a polymer-cement compound; flush tools with “AkvaVIS Cleaner”; re-injection through the same packers is possible within 2–3 h |
| Application temperature | not below +5 °C |
| Curing | pot life 2–3 h; full polymerisation 24 h (20 °C); reaction with 2% water 90–120 s, with 10% water 120–180 s |
| Key properties | mix viscosity 150 mPa·s (75 mPa·s by rotational viscometer at 20 °C); density 1.1±0.05 g/cm³; glass transition temperature −35 °C; volume increase on contact with water — none or insignificant; surface tension 35 mN/m; penetrates cracks from 0.2 mm; does not become brittle |
| Shelf life | 12 months in a dry warm place in the original packaging at +10…+25 °C |
| Standards | STO 69626291-001-2012; included in the Moscow Territorial Construction Catalogue (MTSK); in the List of Innovative Products of the Moscow Innovation Agency (letter No. AIM-01-07-295/21 of 12.05.2021) |
