Why Georgetown projects need a tailored approach
Georgetown sits on Halton Till with shallow shale on the north and east edges of town, and the homes we work on are spread across neighbourhoods like Georgetown South, Park District, Delrex, Moore Park, Glen Williams and along Mountainview Road North. Older Georgetown South lots near the Credit River have alluvium and high water table; newer subdivisions off Mountainview Road North sit on tighter till that drains slowly. Combined with Snow belt, more severe freeze-thaw than the lakeshore, escarpment runoff after heavy rain, this changes how we design the slab and the base.
We pull permits where needed through Town of Halton Hills Building Department (1 Halton Hills Drive), so the work is documented and inspected, not buried under landscaping. Whether you are in postal code area L7G, we serve every Halton Hills address with the same crew, the same supervisor, and the same written quote.

How we waterproof a Georgetown foundation properly
- Excavation: dig the full depth of the foundation wall to the top of the footing, sloped sides and shoring per OHSA where required.
- Wall prep: pressure-wash the wall, repair active cracks with hydraulic cement and polyurethane injection, then parge to a smooth surface.
- Membrane: trowel-applied rubberized asphalt membrane (e.g., Blueskin WP200, Tremco TremPro 644) at 60-mil minimum, primed and lapped.
- Drainage layer: dimple board (Delta-MS or Platon) mechanically fastened over the membrane, terminated above grade with a termination strip.
- Weeping tile: 100 mm perforated PVC pipe in 19 mm clear stone wrapped in non-woven filter fabric, sloped to a sump or gravity outlet.
- Backfill: compacted Granular B in 200 mm lifts, with topsoil restored to original grade plus positive 2 percent slope away from the house.
Our waterproofing process
- Step 1. Diagnosis. We locate the leak, check basement humidity, inspect existing weeping tile cleanouts, and confirm whether interior or exterior work is correct for the failure mode.
- Step 2. Excavation. Equipment access marked, locates called (Ontario One Call), then careful machine excavation to footing depth with proper shoring.
- Step 3. Wall repair and membrane. Cracks repaired, parging where the wall is rough, then primer and rubberized membrane to spec.
- Step 4. Drainage and weeping tile. Dimple board fastened, new weeping tile placed in clear stone, filter fabric wrapped, and connected to the sump or gravity outlet.
- Step 5. Backfill and grading. Granular backfill compacted in lifts, then topsoil and final grading sloped away from the foundation.
- Step 6. Restoration. Walkways, driveway sections, or landscaping disturbed during excavation are restored to original or better condition.
Frequently asked questions about waterproofing in Georgetown
These are the questions we are asked most often when quoting jobs in Georgetown and surrounding Halton Hills communities.
+ Why exterior waterproofing instead of an interior patch?
Interior patches stop water that has already entered the wall. They do not stop the wall from getting wet or freezing in the wintertime. Georgetown homes on Halton Till with shallow shale on the north and east edges of town need exterior membrane and proper weeping tile to keep the wall dry in the first place. Interior systems are a last resort, not a first-line fix.
+ How long does a waterproofing job take?
A typical Georgetown home (one wall, 30 to 35 ft long) is 3-5 working days from excavation to final grading. Full-perimeter jobs are 7-10 days. We work weather-permitting; rubberized membrane needs a dry wall to bond properly.
+ Do I need a permit?
A waterproofing-only job that does not alter the structure typically does not need a building permit through Town of Halton Hills Building Department (1 Halton Hills Drive). Replacing the weeping tile is plumbing work that can require a plumbing permit depending on connection to municipal storm. We confirm before scheduling.
+ Will my driveway or patio survive the dig?
Most of the time, no, not the section directly above the wall being excavated. We tell homeowners up-front what has to come out and we restore concrete, interlock, or asphalt as part of the job. Mature trees within 3 m of the wall are also a flag we discuss before quoting.
+ Can you do this work in winter in Georgetown?
Yes, but cold-weather waterproofing is harder. Georgetown's Snow belt winters mean frozen ground, slower membrane cure, and dimple-board fastening through frozen soil. We prefer to do this work April through November and schedule emergencies in winter only when the basement is actively flooding.
+ What warranty comes with the work?
We provide a written workmanship warranty plus the manufacturer warranty on the membrane and dimple board. Most rubberized membrane systems carry a 10-year manufacturer warranty when installed to spec, which is what we install to.
