Exterior membrane systems, footing drains, and corrected grading tackle Columbus, OH water intrusion at the source, before it ever reaches the interior wall.

Exterior work only pays off if the membrane, footing drain, and grading are all addressed together — fixing one without the others often leaves the underlying pressure problem unresolved. We scope the full picture before recommending excavation.
We call in utility locates before any digging starts, standard on every Columbus, OH exterior job.
Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.
Landscaping restoration is included in the scope, not billed as a separate surprise line item.
Membrane seams are overlapped and sealed to manufacturer spec so the barrier performs as designed for decades, not just years.

We scope every Exterior Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.
This is the most comprehensive Columbus, OH 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 Columbus, OH 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.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.

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.
We explain what's included in landscaping restoration so there's no confusion after backfill.
Excavation, membrane installation, and backfill for a typical residential wall section usually take a few days depending on access and weather.

— Columbus Homeowner
"Footing drain from the original builder had failed completely. New one actually slopes correctly and moves water like it should."

We'll recommend the right approach based on what the inspection actually finds.
We discuss landscaping impact during the estimate so there are no surprises.
Excavation typically goes down to the footing, which varies by home but is often four to eight feet depending on foundation depth.
Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.
Yes — grading correction and downspout extension are often standalone fixes that resolve a surprising number of Columbus, OH water intrusion issues on their own.
