Why Choose Us

Why Pontiac, MI Property Owners Choose SGP Waterproofing for Interior Drainage System

Drain tile that isn't sloped correctly is one of the most common installation failures we see when repairing someone else's prior work — water simply pools instead of flowing to the basin. We verify slope with a level, not by eye.

What We Do

The Full Scope of Our Pontiac, MI Interior Drainage System Work

Every Pontiac, MI Interior Drainage System job starts with an inspection, not a generic package — here's what that typically includes.

Interior Drainage

Perimeter Drain Tile Installation

A channel is cut along the slab edge, perforated pipe is laid with proper slope, and gravel backfill allows water to flow freely into the drain.

Interior Drainage

Sump Basin Tie-In

Every interior drain system needs a sump basin as its endpoint — we size the basin and pump to match the drain tile's expected inflow.

Interior Drainage

Baseboard Drainage Channel Systems

For finished basements where cutting the slab isn't practical, a baseboard channel system captures wall seepage without disturbing existing flooring.

Interior Drainage

Cove Joint Sealing & Drain Tie-In

The cove joint where wall meets floor is sealed and tied directly into the drain system so water is captured right at the entry point.

Interior Drainage

Drain Tile Cleaning & Repair

Existing drain tile that's clogged with silt or has failed slope can often be cleaned or repaired rather than fully replaced.

Customer Reviews

What Pontiac, MI Customers Say About Our Interior Drainage System Work

Top rated local Interior Drainage System specialists in Pontiac, MI
★★★★★

"Water was coming in along one wall every heavy rain. They installed targeted drain tile just on that section instead of charging us for the whole perimeter."

— Pontiac Homeowner

— Pontiac Customer

★★★★★

"Explained the slope requirements in a way that actually made sense, not just technical jargon."

FAQ

Frequently Asked Questions About Interior Drainage System

Do I need drain tile around the entire perimeter?

Full perimeter systems make sense when multiple walls show signs of intrusion or as preventive coverage.

What's the difference between drain tile and a baseboard channel system?

Drain tile requires cutting the slab; a baseboard channel is a lower-disruption alternative that captures wall seepage without floor demolition.

Can you repair existing drain tile instead of replacing it?

{Sometimes — if the pipe itself is intact but clogged with silt, cleaning can restore function without a full re-installation.|We camera-inspect where accessible to make that determination before recommending replacement.}

How is my sump basin sized for the drain system?

Basin size is based on expected water inflow from the drain tile's linear footage and your Pontiac, MI area's typical rainfall intensity.

Will installing drain tile disrupt my finished basement?

If disruption is a major concern, we can discuss the baseboard channel alternative instead.

How long does interior drainage installation take?

We give you a realistic timeline in the written quote based on your specific basement layout.
