Slab foundation building in Orange TX - built for the soil under your house

We give you a written figure after I've seen the lot and the design, because the price of a house slab comes from the engineer's plan and the ground, not square footage alone. Fill is the biggest swing, since Texas engineering guidance calls for the beams to reach below loose, non-engineered fill with deeper beams, spread footings or piers, and piers are generally the most cost-effective way once fill runs deeper than about three feet. After that it's the size and shape of the house, which slab type the design calls for and how high the pad has to sit.

Texas engineering guidance says you should, because slabs on expansive clay or fill are more likely to move and be damaged, so it calls for a licensed engineer to design the foundation on those sites. The same guidance calls for a geotechnical engineer, the soils engineer, to study the ground and write a report before the design starts. Plan on the report and the design before the concrete gets priced, and if you already have them, bring them to the estimate.

A post-tensioned slab is worth asking your engineer about, because the Post-Tensioning Institute, a national trade group, calls it a cost-efficient choice for homes on shrink-swell soils and says it performs better than a slab without prestressing. In a post-tensioned slab, steel cables run through the concrete and get pulled tight after the pour, holding the slab in compression so it resists the ground moving under it. The engineer's design makes the final call, and we build to whichever one it calls for.

In the City of Orange, building permits cover new construction and alterations, and the application goes to the city's Planning and Community Development Department by mail or email, which you can start from the city's new construction page. The city then reviews the plans and inspects the work against the building codes and the approved site plan. We're licensed and fully insured, and as I said up top, we handle the permit side with whichever office covers your address.

Plan for an elevation certificate, because the city's permit application says all work in a special flood hazard area needs one. The city uses the Base Flood Elevation, the height floodwater is expected to reach in the base flood, as the rule for raising or floodproofing a building, and where your house sits against it sets your flood insurance premium, so the height of the pad matters for more than looks. Apart from flood rules, Texas engineering guidance generally puts the top of the slab at least eight inches above the finished soil beside it to keep dampness out.

Yes, in unincorporated Orange County, state law requires inspections on any building with living quarters, including one at the foundation stage before the concrete goes in. Licensed engineers, registered architects and inspectors licensed by the Texas Real Estate Commission can do them, and where county rules apply, the county also requires a Development Permit for any building built or moved onto a property. City and county rules differ by address, which is why we check yours first, and we work in the city, out in the county and in the cities around Orange on both sides of the state line, from Beaumont and Port Arthur over to Lake Charles and Sulphur.
