Mapei Planiseal 288 is a two-component cementitious waterproofing system. It combines a polymer-modified powder (Part A) with a liquid additive (Part B) to create a flexible and durable waterproof barrier designed for areas exposed to constant water pressure. It forms a fully bonded membrane on concrete and masonry substrates.
Suitable for both positive and negative water pressure, Planiseal 288 is ideal for basements, foundations, retaining walls, water tanks, pools, and wet areas. It offers strong adhesion, crack-bridging performance, and long-term protection for both new construction and remedial waterproofing applications.
