The Answer to Slopes, Erosion, and Uneven Ground
A concrete retaining wall turns a problem slope into usable, stable ground. Retaining walls hold back soil, while stem walls lift a building’s foundation up to a level height on uneven land. HillCo Concrete builds both for homes and businesses across the Austin metro and Texas Hill Country, where hills and grade changes are part of everyday life.
These walls control erosion, create flat space, and support structures where the ground won’t cooperate. We build each one with the strength and care it demands.
What Retaining and Stem Walls Are
A retaining wall is a poured concrete wall that resists the pressure of the soil behind it. A stem wall sits on a footing and carries a building’s floor up to the right height above grade. Both depend on solid footings, proper reinforcement, and good drainage to last.
Types of Walls We Build
- Retaining Walls – Walls that hold back soil on slopes, level out yards and sites, and help stop erosion.
- Stem Walls – Walls that rise from a footing to support a building’s floor, often used on sloped lots.
How We Build Retaining and Stem Walls
- Site Review – We look at the slope, soil, and drainage before planning the wall.
- Footing First – Every wall starts with a solid footing poured to plan.
- Forms and Steel – We set wall forms and place reinforcement for strength.
- Batch-Tested Pour – Chris tests moisture and watches the mix on each load before we fill the forms.
- Drainage and Backfill – We plan for water behind the wall so pressure doesn’t build up.

Benefits of Concrete Walls in the Austin Metro and Hill Country
- Stops Soil From Sliding – Retaining walls hold back earth on Hill Country slopes.
