Wetisol Spray-300 — polyurea for waterproofing and floors
Hot-spray polyurea for foundations, tanks, roofs and tunnels, also suitable for protective floor coatings; elongation 250–350%.

The reaction rate of WETISOL I-5107 FG is set with an accelerator: without it the resin remains workable for at least 40 min, and with 1.0% accelerator it reacts completely in 1 min 5 s. The low-viscosity two-component compound forms a watertight membrane, does not need water for polymerisation and increases in volume to a limited extent on contact with it. It is used to strengthen fractured soils, fill large voids, seal service penetrations, embedded parts, precast reinforced concrete joints and expansion joints, create horizontal cut-off barriers and strengthen brick masonry. Service — from −40 to +60 °C.

| Base | two-component low-viscosity polyurethane-based injection compound with adjustable reaction time (WETISOL I-5107 Accelerator); forms a watertight membrane, increases in volume to a limited extent on contact with water; no water is required for polymerisation |
| Colour | cured — homogeneous yellowish gel or foam; comp. A — transparent or opalescent yellowish liquid; comp. B — yellowish to brownish liquid |
| Packaging | 10 kg metal buckets (A+B kit); 0.1 kg polymer bottle of WETISOL I-5107 Accelerator |
| Application method | increasing the strength, stability and watertightness of soils, resin treatment of fractured soils, filling of large voids and cracks, prevention of water inflow; filling of cracks, joints and voids in above-ground and underground engineering structures; sealing of service penetrations, embedded elements, precast reinforced concrete joints, expansion joints; horizontal cut-off barrier, bonding and strengthening of brick masonry; preliminary survey of the structure; clean cracks and voids with compressed air or a high-pressure water jet; two-component pump ZOGEL ZP-14P200-2K with static mixers (30 cm spiral or a set of 20); packers Z23016, Z23005, Z23154, Z23172, Z23249; centres at a distance of ½ the element thickness, staggered at a spacing of ½ the thickness, holes at 40–50°; for cut-off barriers and membranes — holes at 90° to a depth of 1/3–2/3 of the thickness; vertical joints — from bottom to top until the pressure rises or resin comes out of the adjacent hole; A:B = 1:1 by volume; stir the accelerator and add it only to comp. A (dosage relative to the A+B mix); if viscosity increases, flush the pump with WETISOL S-Clean; tools — solvent 646 |
