When do you need waterproofing?

Industry specialist Waterproofing Direct notes that waterproofing keeps water, water vapour, soil moisture or liquid water under pressure from flowing through a material.

According to the International Residential Code, a building should contain waterproofing from the point the footing of the building begins to the point there is soil water. Concrete is porous thus will soak up water via capillary action if you do not treat the aggregate.

Also, waterproofing materials are flexible and maintain their elasticity, so they will cover cracks should they develop in future.

Damp proofing

Damp proofing uses a sealant on the foundation’s exterior to control water vapour that comes from soil moisture meaning liquid water can flow between the damp proofing materials. So, you should not use damp proofing in areas with high water tables.

Damp proofing products are thin and cannot seal large cracks; it is not advisable to use in areas where the ties may protrude from the surface. Should you need to use damp proofing in place of waterproofing, ensure there is proper foundation drainage to keep hydrostatic pressure at a minimum.

Waterproofing is damp proofing with more performance ability. Waterproofing will act as a stable seal against water and keep your structure in shape for occupation. You may, however, consider using damp proofing if you live in a dry climate and you only need to keep the areas below grade comfortable.
