Pool Excavation in Markham — Vinyl, Fiberglass, Concrete
We are OCM Excavation & Construction, and we dig pools across Markham — Unionville, Cathedraltown, Berczy Village, Cornell, Box Grove, Greensborough, and Markham Village. Vinyl liner, fiberglass shell, or poured concrete — we cut the hole to spec, haul the spoil, and leave the site square for your pool builder to start shell work the next morning. If you are pricing a backyard pool in Markham, call us at 416-317-3090 for a site walk and a fixed quote.
Pool Types We Excavate in Markham
Most pool excavation Markham homeowners book falls into three buckets, and each one changes how we dig:
- Vinyl liner pools — rectangular or freeform, typically 16×32 to 20×40, depth 3 ft to 8 ft. Over-dig of about 12 inches for wall panels and backfill. Most common in Berczy and Greensborough subdivisions.
- Fiberglass shell pools — pre-cast shell drops in one piece. Excavation has to match the shell drawing within tight tolerance, with a clean gravel base. Cathedraltown estate lots are a regular call.
- Concrete (gunite/shotcrete) pools — custom shapes, deeper hopper ends, tanning ledges, raised spas. Bigger hole, more spoil, longer dig. Common on Unionville and Cathedraltown custom builds.
If your pool company has handed you a stamped layout, send it over. We will price the dig off the drawing instead of guessing on site.
Our Pool Dig Process in Markham
Every pool dig in Markham runs through the same steps. The order does not change — the equipment does.
- Locates and layout. Ontario One Call locates before steel hits dirt. Pool builder stakes the corners; we shoot grade off the benchmark.
- Access protection. Plywood the driveway and the path through the side yard. Berczy and Unionville lots usually have interlock that does not forgive tracked machines.
- Temporary fence. Markham requires the pool enclosure in place before the pool is filled. We coordinate temp fencing at the dig stage so the open hole stays compliant.
- The dig. Mini-excavator (3 to 5 tonne) for tight 4 ft to 6 ft gates, full-size 8 to 14 tonne for Cathedraltown estate lots and rear-lane Cornell access.
- Spoil hauling. Tandem or tri-axle dumps to an approved receiving site under O. Reg. 406/19 excess soil rules. We track tickets.
- Fine grade and handoff. Bottom shot to depth, walls cut clean, gravel base if the shell needs it. Pool builder walks in.
Markham Pool Enclosure Permit — What You Need to Know
Markham requires a Pool Enclosure Permit from Building Standards before work begins on any pool — inground or above-ground — that holds water deeper than 0.6 m (24 inches). That covers basically every backyard pool we dig.
- Fence height: minimum 1.2 m (4 ft), maximum 1.8 m (6 ft)
- Setback: 1.2 m (4 ft) minimum from the property line
- Gates: self-closing, self-latching, latch on the interior face near the top
- Governing by-law: Fence By-law 277-97
- Fines for non-compliance: up to $5,000
Most Markham pool builders pull the enclosure permit as part of the pool package. If yours is not, get it filed before we dig — the City will stop a non-compliant site.
Site Issues We Hit in Markham
Markham is not one site condition — it is six neighbourhoods with six different problems.
- Unionville heritage district — protected trees with DBH of 20 cm or more fall under Tree By-law 2023-164. Permit needed to remove or injure. We work around root zones with hand digging at the edges.
- Cathedraltown estate lots — full-size machine access, but rear yards slope. Expect over-excavation on the low side for retaining or stepped decking.
- Berczy and Greensborough — 4 ft to 6 ft side gates, mini-excavator only, interlock everywhere. Plywood and Lexan board on every run.
- Cornell rear-lane housing — lane access for spoil trucks is a win. We stage bins off the lane instead of the driveway.
- Box Grove and east Markham — properties near the Rouge River corridor fall under TRCA Ontario Regulation 41/24. Permit required for digs in regulated valley lands or near watercourses.
- Soils — mixed clay and engineered fill on newer subdivisions. Spring digs in clay get sloppy fast; we pump and sleeve as needed.
Why Markham Homeowners Hire a Pool Digger Separately
Plenty of pool builders sub the dig out anyway. Booking your pool digger Markham directly with us means one less margin in the stack, direct accountability for the hole, and a crew that shows up with the right machine for your gate. We have been excavating in the GTA long enough to read a property in a 20-minute site walk — soil, slope, access, trees, services. You get a real number, not a placeholder.

Frequently Asked Questions
How long does a pool excavation take in Markham?
A standard vinyl or fiberglass dig is one to two working days on site, plus haul-off. Concrete pools with hopper ends, tanning ledges, or raised spas can run three to four days. Tight Berczy or Greensborough access can add a day because the mini-excavator moves smaller volumes per cycle than a full-size machine.
Do I need a permit to dig my pool in Markham?
You need a Pool Enclosure Permit from Markham Building Standards before work starts on any pool deeper than 0.6 m. You may also need a TRCA permit if your lot touches the Rouge River corridor in Box Grove or Cornell, and a tree permit under By-law 2023-164 if a protected tree (20 cm DBH or larger) is in the dig zone.
Can you get a mini-excavator through a 4-foot side gate?
Yes. Our 3-tonne mini fits through a 4 ft gate with the cab tucked. For 3.5 ft or narrower, we use a smaller compact unit and accept the longer dig time. We will measure your tightest pinch point on the site walk so there are no surprises on dig day.
Where does the spoil from my pool go?
Pool spoil leaves the site under Ontario Regulation 406/19 excess soil rules. We haul to an approved receiving site and keep the load tickets on file. A standard inground pool generates roughly 80 to 150 cubic metres of spoil — that is six to twelve tandem loads.
Do you work with my pool builder, or do I have to use yours?
We work with whichever Markham pool company you have hired. Send us the stamped pool drawing and the builder contact, and we coordinate the dig date directly with them so the shell, panels, or steel cage lands the same week the hole is cut.
What does pool excavation cost in Markham?
Pricing depends on pool size, depth, soil, access, and haul distance. A straightforward vinyl dig on an accessible lot is the low end; a deep concrete pool on a heritage Unionville lot with hand-protected trees is the high end. Call 416-317-3090 for a real number after a site walk — we do not quote pool digs sight-unseen.
