Built as a collaboration between Trevor Tynes SEO and MK Contracting & Demolition, Lambton Waterproofing follows the proven model of digital-first local brands like ConcreteSarnia.ca — connecting homeowners to trusted, family-owned contractors through modern online visibility and unmatched local expertise.
We’re not just another waterproofing company. We’re a family-run team with a singular focus: permanent exterior basement waterproofing and foundation leak repair that protects your home the right way — from the outside in.
Why Choose Exterior Basement Waterproofing?
Too many homeowners waste money on interior fixes — painting walls, sealing floors, or applying coatings that only hide symptoms. Exterior waterproofing addresses the source of the problem:
✅ Excavates around your foundation
✅ Installs modern french drain (weeping tile) systems
✅ Seals foundation cracks with commercial-grade membranes & sealers
✅ Applies exterior waterproofing barriers
✅ Corrects grading and downspouts to direct water away
This prevents mold, structural damage, basement flooding, and recurring repairs — while preserving your home’s value.

We fully excavate around your foundation, repair cracks, apply waterproof membranes, and rebuild your drainage system. This is the most effective long-term solution to keep your basement dry and your foundation protected.
French Drain Installation
We install modern french drains (weeping tile systems) around your home to relieve hydrostatic pressure and redirect groundwater away from your foundation before it can cause damage.
