Q

What are the different types of basement waterproofing?

A

Type A - Barrier Protection
A casing is introduced inside or outside the building to stop water from entering the building material. This type is used when there is no primary protection against water.

Type B - Structurally Integral Protection
The building is constructed to resist water penetration from the ground. For example, water resistant concrete can be used.

Type C - Cavity Drainage.
An internal cavity is created to manage and depressurize water that enters the building. This is the most modern method of basement waterproofing.

The best type of waterproofing for a basement depends on the ground conditions and how the building will be used.

Spandrel panels
Can be made of opaque glass or coated aluminum, and are used to disguise the ceiling zone and floor slab edge.

Toughened glass
Used in single-pane glazing or in the outer pane of an insulated glass unit at height. It has superior tensile strength to laminated and monolithic annealed glass, making it resistant to thermal stress from heat build-up.
