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.
New-construction helical foundations · coastal SC & NC
Helical piles before the house goes up.
TrueLine Helical installs open-ground helical foundations for custom homes on soft coastal soils, flood-zone lots, and raised-floor builds within about 100 miles of North Myrtle Beach. We review your plans, coordinate pile layout with the engineer of record, and return torque logs with the as-built.

Built for coastal pads
Why builders and engineers specify helicals on new homes.
Soft sand, marsh organics, high groundwater, and flood-zone uplift are everyday conditions near North Myrtle Beach. Steel helical piles reach deeper bearing with little spoil, no pile cure wait, and a torque record for the engineer.
New-construction foundations
Benefits on a new build
What open-ground helicals give the schedule and the engineer.
Soft coastal and marsh soils
Reach a deeper bearing layer under loose sand, fill, and organics common along the Grand Strand and Lowcountry.
Flood zones and raised floors
Detail for compression, uplift, and lateral load when the home is elevated or mapped in a flood zone.
No concrete cure wait on the pile
Steel piles are ready for the footing or grade-beam connection once installed and accepted — the pile itself does not cure.
Quick open-ground install
A typical new-home array often installs in a day, depending on pile count, depth, access, and weather. Bid the job you have.
Torque-verified capacity log
Installation torque is recorded per pier for the engineer of record to review against the design correlation.
Hot-dip galvanized (ASTM A123)
Coastal corrosion protection by hot-dip galvanizing unless the engineer specifies another coating or section.
Minimal site disturbance
Rotation advances the pile with little spoil — useful on finished landscaping plans and soft, wet pads.
Works on tight lots
Compact equipment fits many residential sites where large excavators or open shafts are impractical.
Applications
Custom homes first. Coastal conditions in mind.
custom homes
Custom homes on soft coastal soils
Helical piles installed on open ground before the house is built — for pads that need deeper bearing than a shallow footing.
flood elevated
Flood zones and elevated / raised-floor homes
Uplift and lateral demands matter as much as compression when a home is raised or sits in a mapped flood zone.
tight lots
Tight lots and minimal site disturbance
Compact equipment and little spoil — useful on marsh-edge and infill lots where a large open excavation is hard.
engineer coordination
Plan review and engineer coordination
We work from your plans and geotech, coordinate pile layout with the engineer of record, and hand back torque logs and an as-built.
How a build install works
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.

ASTM A123Hot-dip galvanizing for coastal exposure unless the engineer specifies otherwise.
Also offered
Spray foam insulation for the same build.
For custom home builders, spray foam can be quoted with the helical foundation package — one crew for the piles and the insulation. Open-cell and closed-cell options for walls, attics, conditioned crawl spaces, and the underside of raised floors on coastal and flood-zone homes.
