Newton Hydrocoat 107 Elastic 2K – Flexible Two-Part Cementitious Waterproofing (30 kg)
Newton Hydrocoat 10 Elastic 2K is a flexible, two-component cementitious waterproofing membrane designed to provide durable, monolithic waterproof protection for both internal and external concrete and masonry structures.
Combined contents are 30kg, with 3.2kg/m2 coverage & 2mm membrane thickness.
Supplied as a liquid Part A and a powder Part B, the system reacts to form a tough, elastomeric coating capable of bridging small cracks, accommodating minor substrate movement and resisting moisture under positive and negative water pressure. Hydrocoat 107 Elastic 2K is ideal for applications where flexibility and adhesion to varied substrates are critical.
This membrane is commonly specified for basements, water tanks, lift pits, structural slabs, retaining walls and other wet environments. It can be applied by trowel or spray, making it suitable for horizontal, vertical and overhead surfaces. The cured membrane provides a smooth, tough barrier with excellent chemical resistance and is fully compatible with Newton Hydrocoat reinforcement tapes and accessories.
