Why Choose Us

Why Oswego, KS Property Owners Choose SGP Waterproofing for Exterior Waterproofing

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.

1

Licensed Excavation & Waterproofing Crews

Exterior work involves excavation near the foundation, and every crew member is trained and insured for that specific scope.

2

Local Equipment Staging

Excavation equipment and membrane materials are staged locally so an exterior project doesn't wait on out-of-town logistics.

3

Flat-Rate Excavation Pricing

Landscaping restoration is included in the scope, not billed as a separate surprise line item.

4

Dimpled Membrane & Footing Drain Systems

We install dimpled membrane rated for below-grade use, paired with a footing drain that ties into your existing or new drainage system.

What We Do

Comprehensive Exterior Waterproofing Solutions in Oswego, KS

We scope every Exterior Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Exterior

Foundation Excavation & Membrane Installation

This is the most comprehensive Oswego, KS waterproofing fix available, addressing the wall itself rather than just managing water after it gets in.

Exterior

Footing Drain (French Drain) Installation

We slope footing drains correctly during installation, since a flat or reverse-sloped drain simply won't move water.

Exterior

Exterior Grading Correction

We regrade the perimeter to direct surface water away from the wall, typically paired with downspout extensions.

Exterior

Window Well Excavation & Drainage

We also inspect and reseal the window frame itself while the well is open.

Exterior

Downspout & Gutter Extension

This is often bundled with grading correction since the two issues usually show up together.

FAQ

Exterior Waterproofing Questions We Hear Every Week

Will excavation damage my landscaping?▼

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.
