Exterior membrane systems, footing drains, and corrected grading tackle Gastonia, NC water intrusion at the source, before it ever reaches the interior wall.
A lot of Gastonia, NC exterior waterproofing failures trace back to a footing drain that was installed without proper slope, which means it never actually moved water the way it was supposed to. We verify slope during installation, not just at design.
Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.
Weather-dependent scheduling means we plan exterior jobs around Gastonia, NC's rainy season windows when possible.
Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.
Every Gastonia, NC Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Gastonia, NC waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
A perforated footing drain collects groundwater at the base of the foundation and routes it away before it can build pressure against the wall.
Soil that slopes toward the foundation instead of away from it is one of the most common Gastonia, NC water intrusion causes, and it's often the cheapest fix on this list.
Window wells collecting water get excavated, fitted with a gravel bed, and tied into the exterior drain system so they stop acting as a funnel toward the foundation.
This is often bundled with grading correction since the two issues usually show up together.
We ask about grading, downspout placement, and where interior water is showing up to narrow down the likely exterior cause.
A technician walks the exterior perimeter, checks grading slope, and identifies where excavation would be needed for a membrane or footing drain fix.
You'll see linear footage, membrane type, and footing drain scope broken out with pricing before any digging starts.
We restore grading and any disturbed landscaping as the final step before calling the job complete.
"Membrane and footing drain install took three days but the wall that used to weep every storm has been bone dry since."
— Gastonia Homeowner
"They found our downspouts were dumping water two feet from the foundation. Extended them and regraded, and that alone made a noticeable difference."
— Gastonia Customer
"Window well kept flooding every storm. They excavated, added drainage, and resealed the window frame while they were at it."
— Gastonia Homeowner
"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."
— Gastonia Customer
Interior systems manage water after it enters; exterior systems stop water from reaching the wall in the first place, which is more invasive but often more permanent.
Some disruption is unavoidable near the foundation, but we restore grading and replant where reasonable as part of the scope.
Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
We'll walk through both options and their trade-offs so you can make an informed choice.
We'll recommend starting there if the inspection suggests surface water is the primary cause.
Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
