Crystoseal is a ready-for-use (merely add water) concentrated, high strength, cement-based waterproofing slurry incorporating active chemical constituents which, when applied, become active in cementitious substrates and by a crystallisation process provides a waterproof seal within the substrate. Crystoseal waterproofs sound concrete or cement surfaces against water ingress, dampness, ground water and hydrostatic pressure. Crystoseal is suitable for waterproofing both the positive and negative sides of the substrate. It consists of a blend of cements, graded quartz and active chemical constituents and gives a render-like appearance. Crystoseal works by the conversion of free lime in the concrete to insoluble calcium compounds. These seal against capillary ingress of water. Compounds within Crystoseal penetrate in to the substrate where they in turn ‘crystallise’ on contact with moisture and create a waterproof barrier.
Crystoseal is an economical, easily applied method of providing a waterproof barrier to sound and stable concrete or cement based
products such a cement filled block work. It may be used on both new and existing structures. Crystoseal finds particular use on
concrete structures where access is only available to negative side of the structure such as the internal side of retaining walls.
Crystoseal finds applications in concrete or cementitious substrates such as:
• Foundations, basements, tunnels, retaining walls, water retaining structures, ponds, pools, silos and underground structures
