The lack of adequate waterproofing poses a very real threat to the structural integrity of buildings. It also threatens the contents and health of its occupants.
Whether building a new structure or renovating an existing one, Coprox Waterproof Cement Additive is an essential and economical primary waterproofing when laying bricks, concrete, screed or plastering.
How does it work?
When mixed with mortar, screed, concrete or plaster, the crystalline properties of
Coprox Waterproof Cement Additive render the structure and surfaces impervious to the ingress of moisture.
Coprox Waterproof Cement Additive is an essential ingredient in the construction of structural, retaining and boundary walls, floors, showers, basements, wine cellars, underground parking, ponds, swimming pools, reservoirs and water features for the prevention of rising, falling and penetrating damp.
Common damp problems
Rising damp occurs as a result of capillary suction of moisture from the ground into porous masonry building materials such as stone, brick, earth and mortar. It potentially occurs where there is no damp-proof course (DPC), or where the DPC has been damaged or bridged.
Falling damp is caused by downward water penetration from the top of porous masonry walls. This could happen if the top of a boundary wall (coping) is not adequately waterproofed, or because of failed flashings, blocked or leaking gutters, joints that have lost their mortar, and the build-up of dirt and moss on upper surfaces of stone or brickwork.
Penetrating damp occurs as a result of the horizontal ingress of water through gaps (sometimes tiny) in a building’s substrate. Penetrating or horizontal damp can be due to leaking water pipes and unprotected plaster or brick.
