Detention and retention ponds are not just big holes. They are designed volumes with compacted clay benches, engineered emergency spillways, and outlet controls sized to the contributing drainage area.
We dig to your civil engineer's spec — or bring in our partner engineer if you don't have one — and install permit-ready basins for commercial sites, subdivisions, and working farms.
Why it matters
What you get when it's done right.
Permit-ready
Built to SCDHEC and county stormwater standards with as-built documentation.
No downstream lawsuits
Outlet structures sized so peak discharge matches predevelopment rates.
Long service life
Properly compacted clay liners and rip-rap armoring at high-velocity points.
Inspection support
We meet the inspector on-site and turn the punch list around in days, not weeks.
Our process
From first call to final walk-through.
Step 01
Survey & soil eval
Topo shoot, soil borings if needed, confirm seasonal high water table.
Step 02
Design alignment
Coordinate with your engineer on volume, spillway elevation, outlet type.
Step 03
Excavation
Track-hoe excavation, off-haul or on-site spoil placement, bench compaction.
Step 04
Structures & seed
Spillway pour, outlet install, riprap, native seed mix on side slopes.
