Yes, our polyaspartic garage flooring can be applied over a suspended slab. However, it's important to note that while polyaspartic coatings have excellent elongation properties, they are not inherently waterproof. If your garage floor doesn't have built-in waterproofing system installed, we recommend the application of a waterproofing membrane prior to the polyaspartic flooring. Specifically, we use Sikalastic 390 as a waterproofing membrane. This is applied after the concrete grinding and surface repair, ensuring the floor is both durable and protected from potential moisture issues before the polyaspartic coating is applied.
