McLellan Contracting excels on stopping water from entering your home from your roof down to your foundation.

McLellan Contracting has a bullet proof five part process we've been applying on foundation walls since 1995 with 100% success against product failure.

The McLellan 5 Part Process:

  • Grind Cracks & Repair with Hydraulic Cement

  • Parge Coat

  • Waterproof Primer Coat

  • 2 Part Liquid Membrane

  • Fibreglass Reinforced Self-Adhesive Membrane

McLellan Contracting owns all our own excavation & compaction equipment.


Staying true to buying local – the products from our 5 part process are manufactured in Whitby Ontario.
