Frequently Asked Questions

A properly installed concrete driveway typically lasts 25–30 years. In Louisiana's heat and humidity, proper curing and a well-prepared sub-base are critical — surfaces that skip those steps often show cracking and settling within just a few years.

Cracking is most often caused by poor sub-base preparation, insufficient curing time, or soil movement beneath the slab. In northwest Louisiana, heat expansion and occasional freeze-thaw cycles put added stress on concrete, especially surfaces that weren't installed with proper joint spacing.

Mild temperatures between 50°F and 80°F give concrete the best curing conditions. In the Shreveport-Bossier City area, spring and fall are ideal windows — summer heat can cause the surface to dry too fast, leading to shrinkage cracks if the pour isn't carefully managed.

Surface cracks under a quarter-inch wide are often repairable, but widespread crumbling, deep fractures, or slabs that have shifted and settled usually warrant full replacement. The deciding factor is typically the condition of the sub-base — a compromised base will cause any repair to fail prematurely.

Curing allows concrete to reach its full strength through a gradual chemical hardening process. Rushing traffic or load-bearing use onto a fresh slab — especially in Louisiana's summer heat — can permanently weaken the surface and lead to premature cracking and flaking.

Project size, site accessibility, sub-base preparation needs, and the type of finish all drive concrete costs. Existing demolition and debris removal add to the scope. Getting a proper evaluation upfront helps avoid unexpected changes once work is underway.

Clay soils expand when wet and shrink when dry, creating constant movement beneath slabs. Without a properly compacted sub-base that accounts for this cycle, concrete in clay-heavy areas like East Texas and northwest Louisiana is prone to heaving, cracking, and uneven settling over time.

Not without preparation. The existing soil must be graded, compacted, and often reinforced with a gravel base before any pour. Skipping this step is one of the most common reasons concrete surfaces fail — even a structurally sound mix won't perform on an unstable foundation.

Yes — commercial projects typically require thicker slabs, heavier reinforcement, and stricter compliance standards to handle vehicle loads and foot traffic volume. Contractors working on commercial or government sites may also need specific licensing beyond what standard residential work requires.

Avoid heavy loads and chemical deicers during the first 30 days while the slab fully cures. After that, sealing the surface every few years helps repel moisture and slow surface wear. Keeping drainage directed away from the slab also reduces erosion around the edges over time.

LADOTD requires contractors to hold state prequalification before bidding on public concrete work, which involves demonstrating licensed personnel, bonding capacity, and documented experience with DOT-spec scopes like structural paving and right-of-way concrete. Contractors operating in the Shreveport area specifically work within LADOTD District 04 jurisdiction, so relevant local project history in that district is a meaningful indicator of readiness.

Yes — LADOTD projects require concrete work to meet strict state specifications covering mix design, compressive strength, joint placement, and finish tolerances that go beyond typical residential or private commercial standards. Contractors must follow LADOTD Standard Specifications and are subject to state inspection throughout the project, making prior DOT-scope experience an important factor when evaluating who to hire.

Onyx Construction holds licensing across commercial, industrial, and heavy highway and street work, and has hands-on experience meeting LADOTD specifications.
