Plans and geotech
Share structural plans and any geotechnical report. We review reactions, flood zone notes, and access. A visit is not a design and not a substitute for the engineer of record.
Coastal custom homes · SC & NC
Piles that hold. Foam that seals.
New-construction helical foundations and spray foam insulation — quoted together for builders within about 100 miles of North Myrtle Beach.
Two services
Foundation. Insulation. One accountable crew.
Service 01
Helical foundations
Open-ground helical piles for custom homes on soft coastal soils, flood-zone lots, and raised-floor builds — with torque logs for the engineer of record.
Service 02
Spray foam insulation
Open-cell and closed-cell spray foam for walls, attics, conditioned crawls, and the underside of elevated floors — quoted with the foundation package when you want one sub.
Builder package
Foundation to insulation, one sub.
Carolinas competitors usually sell piles or foam — not both. We quote the pad and the envelope so your schedule keeps one crew through framing milestones.
- Helical layout with the engineer of record
- Torque logs and as-built for inspection
- Open- or closed-cell foam from the same plans

Why helicals
Built for soft coastal pads.
Soft coastal and marsh soilsReach a deeper bearing layer under loose sand, fill, and organics common along the Grand Strand and Lowcountry.
Flood zones and raised floorsDetail for compression, uplift, and lateral load when the home is elevated or mapped in a flood zone.
No concrete cure wait on the pileSteel piles are ready for the footing or grade-beam connection once installed and accepted — the pile itself does not cure.
Quick open-ground installA typical new-home array often installs in a day, depending on pile count, depth, access, and weather. Bid the job you have.
Process
Four steps from plans to as-built.
Layout and quote
We coordinate a pile layout with the engineer of record and provide a fixed-price proposal for installation. Torque targets and stop criteria belong to that design.
Install and torque logs
A hydraulic drive head rotates each pile. Depth and torque are recorded. Caps or brackets are set as designed. Weather, tides, and obstructions can change the schedule.
As-built for engineer and inspector
You receive an as-built pile plan and torque log to hand to the engineer of record and the inspector. Sign-off remains with those parties.
Spray foam
Seal the envelope on the same build.
Open-cell for many walls and attics. Closed-cell where density and underside floor sealing matter. No R-value theater on this site — we quote from your drawings.
