Water repellent and Damp Proofing
Background
“PCT 56 WATER REPELLENT TECHNOLOGY” was formulated during 1991 following a R&D venture when an AAC Mining Shaft was threatened with closure due to extensive concrete failure which effectively put the lives of underground personnel at risk.
The concrete failure was caused by excessive underground water that leached the cement from the concrete causing reduced mechanical failure at the areas where shaft guide equipment was fixed to the structure.
Subsequent improvements to the formulation was necessary, and during November 2008 “PCT 56 WATER REPELLENT TECHNOLOGY” was submitted to the SABS for testing.
A joint Risk Assessment of the product was conducted in conjunction with the Harmony Gold Mining Group in accordance with the International Risk Matrix.
Several supporting products have subsequently been formulated, all containing PCT Technology.
“PCT 56 WATER REPELLENT TECHNOLOGY” however remains the “flagship”.
Water or dampness is responsible for 71% of all recorded paint failures!
Water, the most precious life supporting substance known to man is also the greatest destroyer of any age of house or building.
In the form of dampness it can weaken or destroy brickwork, cement or concrete and lead to paint failures.
Rising Damp:
Caused by moisture in the ground penetrating the lower levels of the house or building when no damp course membrane is present or the membrane is broken or breached.
Build up of soil or paving above the damp course level may also lead to moisture penetrating the lower levels of the walls.
Penetrating Damp:
Water or moisture that penetrates from outside walls to the inside is classed as penetrating damp.
Symptoms are dark patches of mold growth and delaminating and peeling paint.
Particularly evident in the immediate vicinity of windows and doors.
Penetration by Gravity:
Water or moisture penetrates the top sections of parapets and by means of force of gravity erratic contamination of bottom wall sections take place.
The symptoms are patches of loose and flaking paint and when the paint film is removed a white substance also known as effluoresense is visible.
Condensation:
Consistent humid areas where excessive water is used such as bathrooms and showers and showers leads to condensation on walls and ceilings and subsequent paint failures.
Features
A red/pink transparent chemical that cures by chemical reaction and obtains permanent water repellent properties when applied to cement surfaces and bricks.
Benefits
Repellent properties are permanent
