Is your Sarnia home dealing with a flooded basement, leaking foundation, or water seeping through your basement floor? While quick fixes exist, the most reliable long-term solution starts outside, where the problem begins. At Lambton Waterproofing, we specialize in interior & exterior basement waterproofing designed to protect Sarnia homes from recurring water damage.
Basement leaks are often symptoms of bigger issues like hydrostatic pressure, poor drainage, or cracks in your foundation walls. Ignoring them leads to mold, structural damage, and endless repairs. Our approach doesn’t just patch the problem—we solve it at the source.
With free inspections, local expertise, and a focus on long-term results, Lambton Waterproofing helps homeowners in Sarnia and Lambton County safeguard their basements and foundations.
Water Proofing for Basement: Our Comprehensive Exterior Drainage Systems
When it comes to water proofing for basement, focusing on the exterior is the smartest investment for long-term protection.
How Our Exterior System Works:
-
Exterior Weeping Tile Installation: We install highly effective French drain systems that collect groundwater before it touches your foundation.
-
Foundation Excavation & Membrane Application: Our team carefully excavates around your foundation, cleans it, then applies a heavy-duty waterproof membrane and foundation sealers. This creates an impermeable barrier on your basement walls.
-
Grading & Downspout Management: We correct improper grading and reroute downspouts to ensure water flows away from your home—not toward it.
Why Exterior Waterproofing Works Best:
-
Stops water before it enters
-
Reduces moisture buildup inside
-
Prevents foundation damage and future leaks
-
Protects crawlspaces and slab foundations too
Basement Sealing and Waterproofing: Tackling Exterior Cracks & Leaks
Waterproofing isn’t just about drainage—it’s about sealing vulnerabilities.
Our Approach to Exterior Crack and Leak Repairs:
-
Foundation Crack Sealing: We locate cracks on exterior walls and seal them using commercial-grade membranes and injection sealants that hold up to Sarnia’s freeze-thaw cycles.
-
Relieving Hydrostatic Pressure: Our waterproofing reduces the pressure that forces water through your basement floors and walls.
-
Targeted Leak Repairs: Whether it’s water coming through the floor or wall joints, we fix it from the outside—permanently.
Addressing these issues from the exterior means you’re not just treating symptoms; you’re removing the cause.
