Septic done properly. Permit to final grade.
Boulder & Beam designs and installs Part 8 septic systems for rural and waterfront properties across Grey-Bruce — full replacements, new installations, and septic coordinated inside larger builds. One licensed crew, one clear scope, no hand-offs.
Three ways we take on septic work.
Whether the old bed has failed or the lot is bare, the job gets the same thing: a licensed design, a clean permit file, and an installation managed like a construction project — because that’s what it is.
Septic pairs naturally with the rest of what we build — additions and new construction, garages and outbuildings — anywhere in our Grey-Bruce service area. Browse recent projects to see the standard of site work.
System replacements
When a bed or tank is at the end of its life, we handle the full swap — decommissioning the old system, designing the new one, and coordinating excavation, installation, and inspection so the property is usable again fast.
New installations
Stand-alone installs for new builds, severances, and vacant lots. Soil testing and setbacks drive the design, so you get a system sized for the house you’re actually building — not a template.
Part of a larger build
Building an addition or new home with us? Septic folds into the same schedule and the same site management — one crew accountable for the whole property instead of trades pointing at each other.
We design and install Part 8 (Ontario Building Code) systems that we build ourselves. We don’t design proprietary or engineered treatment systems, we don’t produce designs for other contractors to install, and we don’t repair failing systems — if a bed is done, we’ll tell you straight and quote the replacement.
A septic install, run like a build.
Most septic horror stories come from skipped steps — no soil data, a rubber-stamp design, no one managing the site. Ours runs in five phases, and you’re told where the project sits at every one.
Site & soil assessment
Test pits, soil evaluation, water table and bedrock depth, and the setbacks that constrain the design — wells, property lines, and the high-water mark on waterfront lots.
PHASE 02System design
A Part 8 design sized to the home’s daily flow — bedrooms, fixtures, and finished area — matched to what the soil can actually accept.
PHASE 03Permit
We prepare and submit the sewage system permit application to your local approval authority and deal with their questions, so you don’t have to.
PHASE 04Installation & inspection
Excavation, tank setting, bed construction, and the mandatory inspections — executed cleanly, with the site kept safe and organized throughout.
Grey-Bruce lots don’t come easy.
Shallow soils over bedrock, high water tables near the lakes, tight cottage lots with setbacks in every direction — the system type falls out of the site, not a catalogue. That’s why assessment comes first.
Waterfront & lakeshore
Setbacks from the high-water mark and seasonal water tables often rule out a conventional bed. Raised and filter beds are routine for us on Georgian Bay and Lake Huron shorelines — it’s a big share of our septic work.
Shallow & rocky ground
Much of the Peninsula sits on thin soil over limestone. Where native soil can’t do the treating, the design brings in the right imported material and bed type instead of pretending the rock isn’t there.
Rural acreage
Space helps, but soil still decides. On farms and backroad properties we also solve the practical problems — access for excavation, protecting the driveway and yard, and keeping the rest of the property working while we dig.
Credentials you can check, not just claim.
Septic is regulated for good reason — it’s a treatment plant buried in your yard. Here’s the paper behind our work.
