Properties
- High elasticity and reversible swelling capacity; increases volume up to 400 % in contact with water.
- Ensures sealing even at high water pressures due to its excellent swelling property, without damaging the concrete.
- The expansion is reversible. The tape recovers its initial volume if there is no water present and maintains its capacity for swelling indefinitely.
- Durable, chemically stable, unaltered material that maintains its swellable properties after dry/wet cycles, ensuring long-term joint sealing.
- Easy and quick application thanks to its lightness, flexibility and ability to withstand deformation.
- Contains no toxic compounds and is environmentally friendly
Datasheets(X)
Concrete joints. Concrete joints subject to permanent immersion in tanks, dams, canals etc. Sealing of joints between prefabricated concrete elements such as voussoirs, caissons, panels etc. Sealing of walls, junctions and structures buried below ground level in foundations, tunnels, galleries etc.
Clean the surface thoroughly. Smooth any imperfections. Remove residues. Patch any holes and make the surface as smooth as possible.
Place the WATERSTOP DM profile between the rebar rods.
To prevent the seal from moving, nail the tape every 30 cm.
Place the tape over the joint, running parallel to it without about 5 cm on either side. Do not overlap the end of one piece of tape with the start of another. MS Polymer can be used to rectify liner, art. no. 0893 225 ...
