The Foundation That Determines How Long Your Pavement Lasts
The asphalt you see on top is only as good as what's underneath it. In Central Texas, where expansive clay soils are the norm and moisture cycles are dramatic, improper base preparation is the leading cause of premature pavement failure. Legacy Paving Co. takes earthwork seriously — because cutting corners underground means calling for repairs above ground in 3–5 years instead of 20.
We provide complete site preparation services including grading, excavation, subgrade correction, lime stabilization, crush stone base installation, and compaction verification. We build the foundation right — so the surface performs for decades, not years.
- Subgrade evaluation first — We assess soil type and condition before recommending any base treatment or stabilization
- Lime stabilization where needed — Chemical treatment of expansive clay soils — the most critical step on many Central Texas sites
- Proper grading & drainage — Correct slope and drainage profile prevents water pooling that destroys pavement from below
- Compaction testing — We verify compaction density before paving begins — not after a failure
- Flex base & road base installation — Correct base depth and material specification for the intended load
- Full-scope capability — Grading through base installation with one crew and one accountability chain
Services We Offer
Every service in this category delivered by our own experienced crew — no subcontracting.
-
Grading
Precision grading for proper slope, drainage, and surface uniformity. Correct drainage profile is the single most important factor in preventing water-related pavement failure.

Excavation
Selective and mass excavation for site development, drainage corrections, utility trenches, and material removal. We haul away unsuitable material and replace with spec material.
Learn More -
Subgrade Stabilization
Lime, cement, or fly ash treatment of weak or expansive subgrade soils. Critical on Central Texas clay sites — prevents the subgrade movement that destroys pavement above.
Learn More -
Lime Stabilization
Chemical treatment of expansive clay subgrades using hydrated lime. Permanently reduces plasticity and moisture sensitivity of the soil, creating a stable platform for pavement.

Base Installation & Road Base Repair
Crushed limestone flex base and road base installation to correct depth. Road base repair for sections where existing base has failed beneath an otherwise repairable surface.
Learn More -
Compaction & Proof Rolling
Roller compaction, compaction testing, and proof rolling to verify subgrade and base stability before paving begins. We don't skip this step.

How Every Project Works
Transparent from the first call to the final walkthrough.
Soil & Site Assessment
We evaluate soil type, bearing capacity, drainage conditions, and existing base before designing the earthwork scope.
Written Scope & Estimate
Detailed earthwork scope including material specs, compaction requirements, and any stabilization treatments — in writing.
Excavation & Removal
Unsuitable material removed, drainage corrections made, utility conflicts resolved before any fill or base work begins.
Stabilization & Base
Lime treatment applied where required, allowed to cure, then flex base installed to correct depth and compacted in lifts.
Compaction Verification
Proof rolling and compaction testing performed before paving crew mobilizes. No shortcuts on this step.
