At EW Enterprise, we thrive on challenges that others shy away from. Our expertise shines brightest when tackling complex residential projects like high end basement foundations. In cases where blueprints lack detail, our team applies a problem solving mentality to keep the project moving forward.
Pouring a basement foundation is a lot more involved than a simple slab on grade foundation, typical of many homes in the Dallas and Fort Worth area. Let's break down this complexity into its core components:
Before any concrete touches the ground, meticulous planning kicks off the process. We review the home’s blueprint, which considers soil quality, drainage needs, and load-bearing requirements. We then assess the site to make sure we can successfully pour the basement according to plan. While architects do a great job of outlining what the finished result should look like, many times there are still a lot of construction details that our team needs to iron out in collaboration with the architect and engineer.
As a full service concrete contractor, we either handle the site excavation process ourselves, or work with the excavation subcontractor to dig the basement according to specifications. This can involve pulling the proper permits and calling dig test to make sure any utility lines are avoided. Typically the dirt is either used in landscaping elsewhere on the property or loaded onto trucks and removed from the site entirely.
For a basement foundation, the perimeter footing and basement floor are sometimes poured at the same time, but typically poured prior to walls or floors. The footing is a strip of thicker concrete around the edge that supports the load of the basement walls as well as the rest of the home. While thickness can vary based on the structural needs of the project, a typical footing depth range is 8-12 inches.
Rebar reinforcement gives strength where it counts most, because even solid rock can crack under pressure without proper support systems in place. Rebar has tremendous tensile strength and is the preferred way to reinforce all the concrete elements of the basement, including the footer, slab, and walls. Typically we’ll embed vertical rebar in the footer. When the walls are poured, the rebar creates an incredibly strong connection to the footer below.
Forming the walls of a basement requires extensive form work. These wooden forms require heavy duty bracing to ensure their stability while the concrete is being poured. The top of the wall may require extra form detail, such as brick ledges and special notches for support beams.
After the concrete walls have been poured and sufficiently cured, we remove the forms. Normally we’ll install a waterproofing membrane to prevent soil moisture from seeping into the basement’s walls. First we apply an adhesive to the exterior of the wall, then we’ll adhere large sheets of heavy duty waterproofing membrane to the basement wall in overlapping sheets from the top of the wall all the way down past the footing. Depending on the application drainage pipes may need to be added prior to backfilling.
With waterproofing complete, it’s time to backfill around the basement walls. Careful packing of the dirt around the basement walls are important to avoid improper settling and moisture related issues around the basement.
We believe basements are an excellent investment when building a new home. Basements provide storm safety during North Texas’ tornado season, increase the square footage of your home, and increase the value of your property.
