TECHNONICOL IC-125-2-SP waterstop — internal, with swelling profile
Internal PVC waterstop with a swelling profile for “slab — wall” and “floor slab — wall” cold joints; two-level protection against water.

TECHNONICOL waterstops of plasticised PVC protect construction and working joints of monolithic reinforced concrete structures against damp, moisture and water under pressure — in underground parts of buildings, metro systems, and road, railway and hydraulic tunnels. The external profiles EC-220 and EC-320-4 also compartmentalise polymer membrane waterproofing, while IC-240-2 and IC-240-6 are installed as internal ones. The parts are joined by welding — with an electromagnetic plate at 450 °C or a hand-held hot-air gun. Elongation at break is 300%, at −20 °C — 200%, the service range is from −40 to +70 °C.
