Crystoseal
ready-for-use (merely add water) concentrated, high strength, cement-based waterproofing slurry
Description
Crystoseal is a ready-for-use (merely add water) concentrated, high strength, cement-based waterproofing slurry incorporating active chemical consituents 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 compunds. 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.
Uses
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 strcture such as the internal side of retaining walls.
Benefits and Advantages
Crystoseal has application where conventional membranes would be unsuitable such as:
- On damp cementitious surfaces.
- There is only access to the negative side of the structure, i.e.
inside surface of a retaining wall or outside of water retaining
structures. - Easy to use. Simply add water, mix and apply by brush or
roller.
