Aquaseal Pro is a water based, cold applied, rubberized, highly flexible, liquid waterproof membrane. 

Solvent free, non-flammable, and forms a highly flexible monolithic waterproof membrane. It has excellent adhesion properties, not only on concrete (both new and existing), but also ICF (Insulated Concrete Forms) and polystyrene sheets, and cures to form a water and vapour proof coating.
