When you are installing a garage foundation slab for your business, you will want the concrete to keep its strength and its appearance even after years of its receiving use and abuse from normal business operations. Here is some insight to help ensure your concrete garage foundation is built to last and for the cured concrete to remain as free of stains and marring as possible.
Install a Proper Foundation
Below your garage's concrete slab, you need to pour and install the appropriate foundation to provide support and proper drainage. This will ensure your garage floor does not sink, crack, or slope after it has been installed and is put to use as a garage floor. So, before you can even begin to pour the concrete you need to have the soil evaluated on the site to determine if it will provide proper drainage under your concrete slab.
Poorly-draining soils need to be covered with a thicker layer of gravel to allow moisture and rain to drain below the garage floor. Installing a gravel foundation that is not thick enough can cause water to pool and collect below your concrete slab. The excessive moisture can cause the soil to erode away, and winter's freezing temperatures can cause the collected moisture to freeze and expand, cracking and damaging your concrete slab.
As a good rule of thumb, it is recommended to increase your gravel foundation layer to double the thickness of your concrete slab when you are installing it onto soil that has poor drainage. The gravel you install also needs to be the right size to create appropriately-sized gaps within the gravel layer to allow adequate drainage. Too-small gravel will create smaller gaps within the gravel layer that are too small to allow proper drainage of moisture and can end up trapping the moisture. Appropriately-sized gravel should be 3/4 of an inch in width and larger.
Seal the Concrete
After your concrete has cured and fully set, it is recommended to seal your concrete to prevent fluids and other materials from staining its surface. Concrete is naturally a porous surface, which can allow fluids of all types to permeate the concrete. Once a fluid has permeated into the pores of your concrete, it can be difficult to fully remove it.
There are many methods you can use to seal your concrete to protect it from fluids that are commonly found and used in a garage. You can apply an epoxy coating, which consists of a layer of primer, paint, and a top sealant coat over a smoothed and sanded surface of your concrete. Often you can choose to have colored decorative vinyl flakes applied onto the painted surface before you apply the sealant top coat.
You can also choose to coat the garage floor in a tinted urethane concrete sealer to protect the concrete against moisture spills and will also give your concrete a shiny high-gloss appearance. You can do complete these projects yourself or hire them to be completed by a commercial concrete professional.
