Even the best membrane leaves water pooling at the base of your foundation if nothing carries it away. Exterior drainage installation from Piedmont Pressure Seal serves Winston-Salem, NC, and communities including Pfafftown, Bethania, and Kernersville, putting a proper drain along the footing so groundwater has a way out. This work happens during the same excavation as waterproofing, which keeps the disruption to one project.
Working from Winston-Salem, NC, since 1989, Piedmont Pressure Seal LLC is a locally owned and fully insured contractor serving the Piedmont Triad. Its exterior drainage installation covers footing drains, gravel and filter fabric envelopes, discharge piping to daylight or a sump, window well drainage, and connections that carry water clear of the foundation. Alongside drainage, the company waterproofs foundations, installs membranes, repairs structural damage, and encapsulates crawl spaces throughout Forsyth, Davidson, and Guilford counties.
Groundwater has to end up somewhere. Reaching the base of a foundation with no drain waiting for it, water sits there, soaks into the footing, and pushes up through the joint where the wall meets the floor.
Plenty of Triad homes were built with a footing drain that stopped working decades ago. Pipe laid without filter fabric silts up from the inside, crushed sections block flow, and outlets disappear under fill and landscaping. Some newer homes skipped the drain entirely, leaving the wall to handle water on its own.
Installing one correctly is mostly about what surrounds the pipe. With the foundation excavated, we set perforated pipe on a bed of washed stone at the footing, wrap the whole envelope in filter fabric, and pitch the line toward a daylight outlet or a sump. Cleanouts and a stone column against the wall let water reach the pipe from every direction.
Once it's in, water moves down the wall and out to the discharge rather than pooling. Hydrostatic pressure drops, the basement stays drier, and the waterproofing above the drain does its job under much easier conditions.
A drain at the base of the wall quietly does more than most homeowners realize.
Standing groundwater presses on walls and floor slabs with real force. A working drain removes that water before the pressure builds. Walls stay where they were built, and seepage through joints drops off sharply.
Silt migrating into gravel is what kills old footing drains. Wrapping stone and pipe in fabric holds fine clay back while letting water through. A new drain outlasts the one it replaced largely because of that envelope.
A perfect drain accomplishes nothing if the pipe ends buried in dirt or above the water it's carrying. Discharge points go where gravity takes over, whether that means daylight on a slope or a sump basin. Every system gets tested with water before backfill.
Wells that hold water send it straight through the window and into the basement. Tying them into the footing drain with a gravel column and pipe gives that water somewhere to go. Skipping them leaves an obvious gap in the system.
Interior systems, sump pumps, and membranes all last longer when exterior drainage takes the first load. Fewer gallons reach the inside of the house. You spend less on the equipment handling whatever makes it past.
Drainage rarely goes in alone, since the excavation opens the door to these services too.
Our exterior waterproofing service pairs the drain with wall preparation, coatings, and membrane for complete below-grade protection. Most projects combine the two from the start.
Sealing the wall surface itself falls under foundation waterproofing, which stops water the drain never gets a chance to catch. The two solve different halves of the same problem.
A dimpled barrier between soil and concrete comes from waterproof membrane installation, and its channels feed straight into the footing drain. Material and drain get designed together.
Drains that work for decades and drains that fail early differ mostly in trench work.
Backfilling a drain with the same clay that came out of the trench guarantees an early failure. Washed stone and proper fabric cost more and happen to be the entire point of the system. Explaining that cost beats cutting it.
Drains need consistent fall from the high point to the outlet, and an inch here or there decides whether water moves. Grades get measured on every job. Nothing depends on the trench looking about right.
Digging around Triad foundations for more than three decades teaches you where water shows up on a given lot. The trade came to Justin Gornto on these same crews before he took over. Experience shortens the guesswork considerably.
Both our drainage and waterproofing projects include a 10% discount for veterans.
Every project we run carries our standing with the Better Business Bureau, the National Association of Home Builders, and the National Federation of Independent Business. Where Delta®-MS goes in above the drain, the Delta®-MS Dry Foundation Guarantee comes with it.
Yes, and retrofitting one is common work on older Triad homes that never had a functioning drain. The project requires excavating to the footing, which is why it usually happens alongside exterior waterproofing. Access around decks, patios, and additions is the main thing shaping the plan.
Properly built systems with fabric and washed stone often last for decades. Older drains laid in bare gravel or without fabric silt up much sooner, sometimes within 15 or 20 years. Replacement makes sense whenever the wall is already exposed for other work.
Footing drains sit at the base of the foundation wall, next to or just above the footing itself, which on a full basement means roughly seven to eight feet down. Crawl space foundations run considerably shallower. Actual depth follows the house rather than a standard number.
Lots without a downhill outlet use a sump basin and pump to lift water to a discharge point away from the house. Dry wells work on some properties depending on soil and local rules. Elevations get checked before anybody promises where water will go.
Most original drains fail because clay silt worked into the stone and pipe over the years with no filter fabric to stop it. Crushed pipe from backfill or equipment and outlets buried during landscaping account for much of the rest. Roots finish off whatever survives those two.
