FROM THE DIRECTOR....


I wish I could burn this as an imprint into the brains of those who are building, or planning renovations, or any form of building that you are thinking of right now that is to be re-modeled or modernized in any form.....

 
 

The truth is that this all needs to be sealed from rain, from damp, from moisture, from the elements.
If the tips below are followed then you will save about
R160 000 on a standard 3 bedroom house with a flat roof over the next 12 years.If it is a commercial office park of about 150 offices, you will be saving R3.25M Rand over the next 12 years. "Anywhere in-between... do the math"



The following points will avoid waterproofing issues in future and alleviate additional expenses

Allow a fillet to be installed @ the vertical/wall junction

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

Allow a 110mm outlet pipe to be installed through walls etc.

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)

Ensure concrete slopes / falls are correct

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

Plaster parapet walls tops at an angle inward away from view

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

Allow a step @ balcony patio border to avoid dust streaking down

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 150mm drop from sliding door to patio floor avoids flooding

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.

Damp proofing of external walls

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)

Waterproof shower walls and floors

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

Seal outlet pipes correctly within concealed areas

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

Cracks in plasterwork should be waterproofed immediately

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
