Wetisol I-5115 — water-reactive polyurethane resin with elastic foam
Wetisol (INGRI)

Wetisol I-5115 — water-reactive polyurethane resin with elastic foam

Injection waterproofing

On contact with water, Wetisol I-5115 resin foams vigorously and hardens into an elastic foam that partially compensates for deformations. It is used for preliminary sealing of water-bearing cracks at water pressures of up to 0.5 atm, filling small and large voids, stopping small and medium water inflows and strengthening soil. After the foam, the crack is finally sealed with WETISOL I-5106 LV resin. Foaming starts after 5–8 s, work is possible at +5…+30 °C, and the A+B kit weighs 10 kg.

Specifications

ManufacturerWetisol (INGRI) — OOO “Ingri”
Typeinjection waterproofing
Useleak repair, foundations and basements, joints and abutments
Basewater-reactive polyurethane injection resin (comp. A) with catalyst (comp. B), solvent-free; on contact with water it foams vigorously and cures, forming an elastic foam
Colourcomp. A — viscous transparent brownish liquid; comp. B — transparent liquid, colourless to yellowish
Packagingkit A+B 10 kg: comp. A 9.09 kg (metal bucket), comp. B 0.91 kg (plastic bottle)
Application methodpreliminary sealing of water-bearing cracks with water pressure up to 0.5 atm; filling and sealing of small and large volumes and voids; stopping small and medium water inflows followed by injection of WETISOL I-5106 LV; the elastic foam partially compensates for deformations; strengthening and binding of soil; at water pressure above 0.5–1 atm — WETISOL I-5137; if there is not enough water in the zone — preliminary or subsequent water injection; one-component pump with hose, packer nozzle and pressure gauge; injection points 50–60 mm from the crack, one on each side, spacing max 200 mm (for membranes — up to +100 mm); holes Ø12 mm (minor repairs) – 30–40 mm (membrane) at 40–50°, depth up to 450–500 mm (for a membrane 600–800 mm); plastic packers up to Ø18 mm; lay injection hoses where possible (mandatory when repairing foundation waterproofing and strengthening soils); A:B = 1:(0.06–0.1) by weight, scales ±1%, mix until homogeneous; before use keep for at least 12 h at +15…+30 °C; cleaning with WETISOL S-Clean, hardened material — mechanically
Application temperaturestructure, water and air +5…+30 °C
Curingstart of foaming 5–8 s, foam rise 40–65 s (at 23 °C, A:B:water = 10:1:0.5)
Key propertiesdensity at 23 °C: comp. A 1.15±0.05 g/cm³, comp. B 1.0±0.05 g/cm³ (GOST 31992.1); foaming start time 5–8 s, foam rise time 40–65 s (23 °C, A:B:water 10:1:0.5; per the TU method); forms an elastic foam; the reaction rate is controlled by the catalyst; service temperature of the cured material from −10 to +50 °C
Consumptionexpansion joints (opening up to 4.0 cm, reinforced concrete slabs up to 40 cm) — 2.0 kg/linear m
Shelf life12 months from the date of manufacture in closed undamaged original containers at +10…+30 °C; reacts with air moisture (a film forms in an open container)
StandardsTU 2257-008-94613022-13 with amendment No. 1
