Wetisol I-212 — methacrylate injection gel

Injection waterproofing

Wetisol I-212 is a methacrylate gel based on special acrylic resins, prepared as a three-component version with water or as a four-component version in which a polymer dispersion replaces the water for higher mechanical properties. It is used to eliminate leaks in cold and expansion joints, cracks, dewatering wells and abutments, to create waterproofing curtains behind the structure, to repair polymer membranes and to consolidate soil. In water the gel increases in volume by more than 25%, without water it slowly shrinks without breaking down, and these changes are reversible.

Specifications

ManufacturerWetisol (INGRI) — OOO “Ingri”
Typeinjection waterproofing
Useleak repair, joints and abutments, foundations and basements
Basemethacrylate injection gel: special acrylic resins and functional additives; 3-component (with water) or 4-component (with component D — an aqueous polymer dispersion instead of water, to improve physical and mechanical properties)
ColourA — transparent colourless liquid; B — transparent liquid, colourless to orange-brown; C — white crystalline powder; D — white liquid
Packagingcomp. A 20 kg; comp. B 1 kg; comp. C 1 kg; comp. D 20 kg (optional)
Application methodinjection waterproofing of leaks: cold and expansion joints, cracks, dewatering wells, abutments; injection behind the structure (waterproofing curtains); repair of waterproofing based on polymer membranes; filling of cast-in injection hoses; soil consolidation; two-component pump ZOGEL ZP-14P200-2K; 2 solutions are prepared: A + B (mix for 2–3 min in the canister) and C + water or D (20 kg, opaque container, 2–3 min); feed (A + B) : (C + water/D) = 1:1 by volume; dosage of B and C 0.5–2.0 wt. % each according to the required gel time; check — mix 50–100 g of each solution for 10–20 s; the A+B mix is stable for several hours (in the cold up to a day), C+water — several days at 25 °C, C+D — several hours; scales ±1%; tools — with clean water
Application temperaturestructure, water and air +5…+25 °C
Curinggel time 2–3.5 min (120–210 s); at 22 °C with water: B/C 0.5% each — 11 min, 1.0% — 5 min, 2.0% — 2.5 min; with dispersion D: 8 / 4 / 2 min; cold and an acidic environment (pH<7) slow it down, an alkaline one accelerates it, metal ions (Cu, Fe) change the rate
Key propertiesdynamic viscosity of comp. A (23 °C) 20±10 mPa·s (GOST 25271); density at 23 °C: A 1.10±0.05, B 0.83±0.04, D 1.04±0.05 g/cm³ (GOST 31992.1); on contact with water the gel increases in volume by more than 25% (compression sealing), without water it slowly shrinks without breaking down, the changes are reversible; resistant to freeze/thaw cycles and water absorption/release cycles; resistant to bacterial and fungal degradation
Shelf life6 months from the date of manufacture in unopened undamaged original containers at +5…+25 °C, away from direct sun
StandardsTU 2241-014-94613022-2013
