Concrete Foundation Contractor

A foundation serves as the anchor for any structure, securely fastening it to the ground while distributing the weight of the walls and frame evenly. A well-built foundation is essential to prevent shifting, settling, or even structural failure.

Concrete foundations do more than just support the building—they offer thermal insulation, keep interior spaces dry by blocking moisture, and resist shifting caused by ground movement. At JS3 Concrete, our foundation contractors in San Antonio pay close attention to every detail that ensures long-term durability. From evaluating soil quality to carefully managing the curing and sealing process, we take every precaution to prevent cracking, crumbling, or future damage.

Types of Concrete Foundation Services We Offer in San Antonio

At JS3 Concrete, we go beyond the standard concrete foundation services typically seen in residential and commercial properties. We specialize in custom foundation designs that provide strength and durability, all while enhancing the overall structure of your building.

Slab-on-Grade Foundations

Slab-on-grade foundations are especially popular in warmer climates and are one of our specialties. In this method, concrete is poured in a single layer onto a prepared site. Before pouring, trenches are dug around the perimeter and throughout the area for a grid layout. The slab, typically 4 to 6 inches thick, is reinforced with steel rebar and is supported by 20- to 30-inch thick perimeter beams.

Post-Tension Slab

The post-tension slab is an affordable foundation option that minimizes cracking. It distributes weight over a larger area, with part of the load being supported by the slab itself. This foundation type incorporates a network of steel cables that can withstand up to 33,000 pounds of pressure. The tension from the cables strengthens the slab and foundation, reducing the risk of cracking.

Pier and Beam Foundation

An alternative to basement or slab foundations, pier and beam foundations feature a crawl space beneath the house, making access to plumbing and electrical systems easier. This type of foundation elevates the structure, reducing the risk of flooding during storms, and is generally more cost-effective to repair compared to a slab foundation.

Strong Enough for Industry. Smooth Enough for Home

Our Foundation Construction Process

At JS3 Concrete, we follow a detailed process for all new construction projects to ensure a strong, durable foundation. Here’s an overview of our procedures:

Ground Breaking and Excavation

Once the lot is graded and tested, we begin by digging trenches for the footings and leveling the area using batter boards.

Footings Dug, Rebar Set & Inspection

Next, we dug the footings and installed rebar reinforcement. After passing a thorough inspection, we pour the footings using a boom pump to deliver the concrete.

Polysteel Installation

We then install Polysteel stem wall forms, which provide insulation for the building’s interior against the cold, and set up the plumbing locations.

Radiant Heat, Plumbing Pipes & Concrete Pouring

The area is prepared for the slab by installing plumbing pipes in their precise locations. Plastic tubing for radiant heat is also laid out, and then concrete is pumped into the area using a boom pump.

Clean-Up and Block Wall Installation

After another detailed inspection, we complete the clean-up process, install the block walls, and prepare the site for the framing crew.
