Across Hwy 90, Hwy 501, Hwy 378, Wild Wing Plantation, Shaftesbury Glen, Historic Conway, and Waccamaw River acreage, driveways face tricky inland clay-to-sand soil transitions. We bring physical paver, Spray Deck, and aggregate samples right to your home.
We coordinate Horry County or SCDOT culvert approvals and HOA packets, protect your lawn and sprinkler lines, and install 4,000 PSI 6"x6" steel-wire-grid concrete ($18–$20 / sq ft) paired with our recommended +$3.00–$5.00 / sq ft 4-inch compacted #57 / ABC stone sub-base upgrade across clean 3–5 day schedules.
How we eliminate builder-slab heaving across Historic Conway, Wild Wing, Shaftesbury, and rural Hwy 90 / Hwy 378 parcels.
Where builder concrete poured directly over unstabilized Conway clay shears and settles along Hwy 90, Hwy 378, and Waccamaw River basins, our 4" compacted #57 / ABC crushed stone sub-base upgrade (+$3.00–$5.00 / sq ft) breaks capillary moisture beneath your 4,000 PSI 6"x6" ASTM A1064 welded wire-grid slab ($18–$20 / sq ft base) for dually trucks, boats, and RVs.
Acreage tracts off Hwy 90, Hwy 501, and Hwy 378 require SCDOT or Horry County encroachment authorization when crossing roadside drainage ditches. We laser-grade swale fall, embed properly sized concrete or double-wall HDPE culverts, and thicken 6-inch turn radii at roadway tie-ins.
New D.R. Horton and Lennar production homes arrive with narrow builder pours lacking third-car or boat pads. We match expansion bays cleanly with dowelled 4,000 PSI concrete, cool-touch Spray Deck ($24–$28 / sq ft), or interlocking pavers set over AASHTO M288 geotextile → #57 stone → ABC road base → 1" M10 granite screenings.
Transparent square-foot pricing showing base concrete, our recommended #57 / ABC clay stabilization upgrade, Spray Deck, and interlocking pavers. 250 sq ft minimum installation ($4,500 minimum project).

| Existing Concrete Tear-Out & Haul-Off | +$2.50 – $4.00 | +$2,000 – $3,200 | Full removal of cracked builder slabs, tree-root extraction, and laser re-grading | Settled 1990s–2010s Conway slabs |
Many older driveways in Historic Conway, Collinswood, and off Hwy 501 were poured at 3.5 inches over raw topsoil without stone drainage or heavy wire reinforcement. Seasonal clay expansion lifts panel edges while heavy truck tires crack unreinforced corners.
Whether you upgrade with a 4-inch compacted #57 / ABC crushed stone sub-base (+$3.00–$5.00 / sq ft) beneath 4,000 PSI 6"x6" welded steel wire-grid concrete or install flexible interlocking pavers cushioned on 1" screeded M10 granite screenings, your driveway handles standing water and heavy axles without heaving.

Conway parcels along Hwy 90, Hwy 378, Hwy 501, and the Waccamaw River basin contain clay and clay-sand transitions that swell when soaked and shrink during summer droughts. Pairing our 4,000 PSI 6"x6" welded steel-wire-grid concrete ($18–$20 / sq ft) with a 4-inch compacted #57 / ABC stone sub-base (+$3.00–$5.00 / sq ft) drains trapped moisture and prevents clay pumping under boats, RVs, and heavy trucks.
Yes. Ditch-crossing aprons along Hwy 90, Hwy 501, Hwy 378, and state secondary routes require SCDOT or Horry County right-of-way encroachment permits and approved culvert sizing. We establish laser swale grades, install pipe to county flowline specs, and pour thickened concrete turn radii.
Every interlocking brick or stone paver driveway ($24–$28 / sq ft) in Conway uses AASHTO M288 woven geotextile fabric to separate clay/sand soil from stone, followed by a #57 crushed stone sub-base, compacted ABC aggregate road base, 1" screeded M10 granite screenings, and 60mm or 80mm ASTM C936 pavers.
Standard 4,000 PSI 6"x6" wire-grid concrete runs $18–$20 / sq ft, with the recommended 4" compacted #57 / ABC stone sub-base upgrade adding +$3.00–$5.00 / sq ft. Cool-touch Spray Deck concrete and interlocking pavers run $24–$28 / sq ft, permeable PICP runs $30–$36 / sq ft, and cracked builder-slab tear-out adds $2.50–$4.00 / sq ft. All projects carry a 250 sq ft ($4,500 minimum) installation threshold.
