Case 1

Remedial

Repair: Application of Water Repeller

This type of solution acts as a hydrophobic surface by penetrating into the pores of the bedding or screed layers and tightening the pores. Hence, water is not allowed to penetrate through. It allows vapour to escape to prevent any development of hydraulic pressure caused by the retained moisture.

Repair: Application of Water Proofer (Silicate based)

This kind of solution reacts with free lime in cementitious materials and seals the pores and cracks in the surface. In fact, as long as moisture and free alkali is present, the reaction will continue and seal up the pores.

Repair: Application Water-based Clear Coating (with polymer particles)

In this treatment, the floor is ponded with the solution and super fine polymer particles are allowed to penetrate into the porous structure to form a permanent and continuous plug.
