We excavate only where necessary and restore landscaping as part of the scope.

A lot of Lancaster, SC 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.
We call in utility locates before any digging starts, standard on every Lancaster, SC 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.
We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.

Every Lancaster, SC Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.
This is the most comprehensive Lancaster, SC waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.
We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.
We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.
We also inspect and reseal the window frame itself while the well is open.
Downspouts discharging within a few feet of the foundation send roof water directly toward the problem — we extend them well clear of the wall.

Photos of the exterior foundation area help us plan equipment and access before the visit.
We flag any utility lines or landscaping features that need special handling during excavation.
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.

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.
We measure your specific foundation during the on-site inspection rather than assuming a standard depth.
Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.
We'll recommend starting there if the inspection suggests surface water is the primary cause.
A typical residential wall section with membrane and footing drain work takes a few days depending on access and weather conditions.
