Save MONEY, with our building TIPS - Waterproofing Africa, We Reign When It Pours

This fillet curve of cement, will reduce the perishing of the waterproofing material at the corner junctions.

It is highly recommended that the minimum of a 110mm outlet pipe
be installed through walls and concrete  areas.
This size is commonly used in the industrial sector for good reason,
as debris will block anything smaller
(75mm might be an exception, if inspected periodically for blockages)

When laying a screed, make sure the fall is correct flowing toward the outlet pipes. Failure to do this will create ponding which will decrease the life expectancy of waterproofing. Furthermore ponding on patios will eventually discolour the tiles

By sloping parapet walls inward at an angle away from the eye allows the rain water to flow backward toward to roof or patio. This avoids dust and rain water streaking down walls

Build a step around the patio edge to barricade the water. This will ensure the water does not flow down the sides of walls, thus again avoiding streaking

Ensure there is enough of a drop from the patio door to the floor level (min 150mm). If this is not done, one will experience continual flooding under the doors damaging carpets/wooden floors etc.

If the exterior soil level is higher than the interior ground level, it is essential that a waterproofing system is to be installed. This application is commonly known as tanking and the waterproofing should protrude 100mm above the ground level. If large amount of drainage water flows toward the wall, a drainage system should be installed (GEO drainage)

Should a shower be waterproofed? YES
This is a common problem when it comes to newly built restrooms. Builders often forget to waterproof showers and bathrooms thus creating major internal damage. Water seeps through tiles and floors creating damp in the lower slab and adjacent walls

Make sure that outlet pipes in walls are sealed or glued correctly. Failure to do this will result in columns and concrete pillars becoming saturated with water. This damp usually spreads at an angle downward through the brickwork

Once there is a visible crack in plasterwork immediate waterproofing action must be taken. If cracks are left exposed to the elements, rain water will seep into the plaster, allowing the plastered to secrete a white powdery substance. This substance is the lime in the cement which bleeds out of the plaster work. Often the case, plaster will need replacing
