contecSEAL 150
contecSEAL 150 is a high-performance metal waterstop designed for sealing construction joints in reinforced concrete structures. Featuring a double-sided special elastic coating, it provides reliable expansion upon contact with water, ensuring complete watertightness even under high hydrostatic pressure.
Ideal for use in basements, tunnels, and water-retaining structures, contecSEAL 150 combines durability with easy installation. Its robust steel core guarantees structural integrity, while the bentonite layer offers active sealing against leaks. Perfect for demanding projects requiring long-term protection and compliance with stringent waterproofing standards.
contecSEAL 150 is intended for the use as a permanent internal seal against pressurised water for construction and control joints in walls and floors and base slabs in impermeable to water concrete constructions (“White tanking”) in building constructions and civil engineering without additional concrete upturn.
The Benefits:
Extremely strong adhesive bond to concrete
Increased leak path
Fresh concrete and labyrinth seals
Elastic, non-rigid mineral coating
Safe application due to a special doublesided elastic coating
Pressure sensitive adhesive bond
Non-stick surface
Fast, effective installation (no protective film required, no additional concrete upstand in base slab to wall joint required)
Embedment depth in concrete at least 3 cm
Water pressure resistance up to 5 bar joint expansion of up to 0.5 mm and embedment depth 3 cm
Tested for joint expansion of up to 1.0 mm at 2 bar water pressure
Suitable for the use in changing water levels
General building authority (abP) test certificate
All the advantages of the traditional systems have been technologically combined into one single product.
The product is mainly installed in the middle of the construction or control joint (base slab to wall, wall to wall, base slab to base slab, wall to floor slab) in the construction part to be waterproofed in in-situ concrete and precast construction. Suitable for horizontal and vertical applications.
