Licensed Exterior Waterproofing service in Galesburg, IL - SGP Waterproofing
Why Choose Us

Four Reasons Our Exterior Waterproofing Clients Don't Call Anyone Else

A lot of Galesburg, IL 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.

1

Licensed Excavation & Waterproofing Crews

We call in utility locates before any digging starts, standard on every Galesburg, IL exterior job.

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

Pricing is quoted per linear foot of foundation wall being treated, based on an on-site measurement, not a phone estimate.

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 Galesburg, IL

Every Galesburg, IL Exterior Waterproofing job starts with an inspection, not a generic package — here's what that typically includes.

Exterior

Foundation Excavation & Membrane Installation

We excavate to the footing, apply a dimpled waterproof membrane directly to the foundation wall, and backfill with proper drainage material.

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

Soil that slopes toward the foundation instead of away from it is one of the most common Galesburg, IL water intrusion causes, and it's often the cheapest fix on this list.

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.

Top rated local Exterior Waterproofing specialists in Galesburg, IL
★★★★★

"Interior fixes hadn't worked for us — turned out the real problem was grading pushing water straight at the foundation. Exterior correction solved it."

— Galesburg Customer

★★★★★

"Appreciated that they called in utility locates before digging near our gas line."

FAQ

What Galesburg, IL Customers Ask Us Most About Exterior Waterproofing

What's the difference between interior and exterior waterproofing?

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.

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.

How deep do you need to excavate?

We measure your specific foundation during the on-site inspection rather than assuming a standard depth.

Is exterior waterproofing more expensive than interior?

Generally yes, since it involves excavation, but it addresses the source of water intrusion rather than managing symptoms after entry.

Can you fix grading without a full exterior membrane project?

We'll recommend starting there if the inspection suggests surface water is the primary cause.

How long does exterior waterproofing take?

Larger projects or difficult access points can extend the timeline, which we'll outline in the written quote.
