Slab foundation building in Round Rock TX - built to match the soil on your lot

A reinforced concrete slab in Round Rock usually costs about $6 to $11 per square foot, and that's the going rate around here, not our quote. Where yours lands depends on the design, because a slab of even thickness, the kind used on less expansive soil, takes more concrete but saves on labor and equipment. I'll price your slab once I've seen the lot and the plans.

For a new home, yes. The City of Round Rock issues building permits for work on any building or structure in the city and in the Chandler Creek and Vista Oaks utility districts, and if your land is outside city limits in Travis County, Travis County Development Services handles permits for all development there. If you're not sure about your project, the city's development technicians at 512-218-5550 can tell you. Before we set a date, we check which office covers your address, and when a permit is needed we handle the application and keep it moving. Contractors who apply in Round Rock have to be registered with the city, and we're licensed and fully insured.

The city says review of a new single-family permit takes about 30 business days once the application is accepted, and it doesn't offer expedited review. The application needs engineered foundation plans, a site plan and architectural plans, so your foundation design has to be done before you apply. I put that wait into the schedule from the start, so nobody's counting on a pour date that can't happen.

The Post-Tensioning Institute, a national trade group, says a post-tensioned slab handles shrink-swell soil well, because the slab is held in compression and resists the strain as the ground moves. It calls these slabs a cost-efficient choice that outperforms a slab without prestress, so they're worth asking about if your lot has that kind of soil. Not every lot here does, which is why I don't pick a slab type until I've seen yours and your engineer has weighed in.

They can. A UT Arlington study found that tree roots dry out the soil, and as it dries and shifts, it puts house foundations at risk. That's why I ask about nearby trees before your plans are final, so the foundation plan can take them into account.

A vapor retarder, a sheet laid under the slab to slow moisture coming up from the ground, is the usual way. National concrete guidance says they're often specified for indoor slabs on the ground where moisture protection is wanted, and your plans will say whether yours gets one. If it does, we lay it before the pour.
