1. What is a Slab on Grade?
A slab on grade is a type of foundation that is constructed directly on the ground, without the need for a basement or crawl space. It is a popular choice for many buildings in Vancouver, BC, due to its cost-effectiveness and ease of construction. However, it requires careful preparation to ensure that it is stable and durable.
2. Why is Slab on Grade Preparation Important?

3. Steps Involved in Slab on Grade Preparation
The slab on grade preparation process typically involves the following steps:
a. Site Preparation: The first step is to prepare the site by clearing it of any debris, vegetation, and obstructions. This ensures that the slab is built on a clean and level surface.
b. Excavation: The next step is to excavate the site to the required depth, taking into account the thickness of the slab and the type of soil it will be built on.
c. Compaction: The excavated soil is then compacted to ensure that it is stable and can support the weight of the slab.
d. Subgrade Preparation: The subgrade is the layer of soil beneath the slab, and it must be prepared to ensure that it is level, compact, and free of any debris.
e. Slab Construction: Once the subgrade is prepared, the slab can be constructed. This typically involves laying a layer of concrete, followed by a layer of insulation and a layer of waterproofing membrane.
f. Finishing Touches: The final step is to add any finishing touches, such as a layer of concrete topping or a decorative finish.
