Culvert installation places large pipes under driveways, access roads, and drainage channels to allow proper water flow underneath while maintaining the road surface above. Lowcountry properties deal with significant rainfall and high water tables — improperly drained driveway crossings erode, wash out, and require constant regrading.
A properly installed culvert resolves drainage problems once and keeps the crossing stable for decades. IronJaw sizes the culvert for your watershed, excavates the trench to proper grade, seats the pipe, backfills, and compacts — leaving a stable, properly drained crossing that meets SCDOT requirements. We serve residential homeowners, farm owners, and commercial developers throughout the Summerville and Charleston area.

Undersized culverts wash out. Culverts installed at the wrong grade back up and flood. Culverts without proper end protection erode from both ends. IronJaw sizes, grades, and finishes every culvert installation to eliminate the problems that bring contractors back for expensive fixes.
Correctly sized and properly installed culverts solve the flooding problem once — no annual regrading for a crossing that washes out every storm.
We install to SCDOT standards for driveway permits and county road crossings — compliance built in, not bolted on.

"IronJaw prepped our homesite from raw land to a compacted pad in under a week. Owner walked the lot with us before quoting — knew exactly what the builder needed. Couldn't have asked for better."
"They installed a culvert on our driveway crossing and regraded the whole approach. Water finally goes where it's supposed to. Should have done it years ago. Professional crew."
"IronJaw built a retaining wall along the back of our property. They included drainage behind the wall without being asked — said it's what prevents failures. Wall looks great, no water issues after two big rains."
Common questions from homeowners, farm owners, and developers about driveway and drainage culvert installation in the Lowcountry.
Call (854) 300-4979$500–$2,500 depending on pipe size and crossing type. Small residential driveway culverts (12"–18" diameter): $500–$900. Standard crossings (18"–24"): $800–$1,400. Large crossings (24"–36"): $1,500–$2,500. Headwall installation is additional.
Culvert sizing depends on the watershed area draining through the crossing — how many acres of land drain to that low point and at what storm intensity. IronJaw assesses your drainage area and recommends the correct diameter. Undersized culverts are the most common culvert failure cause in the Lowcountry.
Most residential driveway culverts are installed in a single day — trench opened, pipe seated, backfilled, surface restored. Larger road crossing culverts with headwalls take 2–3 days.
Culverts crossing state road ditches require an SCDOT encroachment permit. Culverts on county roads require county road department approval. Private property crossings typically don't require a permit unless within a FEMA floodplain. IronJaw advises on your specific situation.
Corrugated metal culverts: 20–30 years with proper installation. HDPE (high-density polyethylene) culverts: 50+ years. We recommend HDPE where budget allows — the cost difference is modest and the lifespan improvement is significant.
Yes — repeated washout is almost always an undersizing problem. We assess the watershed and upsize the culvert so it can handle your actual storm flow. Fix it once instead of regrading after every heavy rain.
