What Happens If You Delay?
A cracked concrete patio becomes a safety liability and gets worse every winter. Water penetrates cracks, freezes, and expands — turning a $2,000 repair into a full rip-out. Delaying also means losing a full season of outdoor use.
Get a Quote NowHow We Work
Step 1: Consultation & Measurement
We measure the space, discuss your vision, and identify the right stone or interlock product for your budget and style.
Step 2: Excavation to Grade
We excavate 10–12 inches, removing organic material and ensuring a proper foundation depth that prevents frost heave.
Step 3: Granular Base Compaction
We install and compact a 6–8 inch granular base — the most critical step for long-term stability. Many contractors skip this. We don't.
Step 4: Bedding Sand Layer
A 1-inch sand layer is screeded perfectly level to create a smooth, consistent surface for stone placement.
Step 5: Stone or Interlock Installation
We lay your chosen material precisely to pattern, cutting and fitting edges for a clean, professional finish.
Step 6: Polymeric Sand & Sealing
We fill joints with polymeric sand and offer optional sealing to lock colour and prevent moss and weed growth.

Frequently Asked Questions
Technical answers from people who do this work every day in Burlington and Oakville.
What base depth is required for a patio in Ontario?
A minimum of 8–10 inches of compacted granular base (Granular A or B) is required for residential patios in Ontario's climate. This depth gets below the active frost zone for most of the province. Cutting corners to 4–6 inches is the #1 cause of heaving, sinking, and joint failure within the first 3 winters.
How do you calculate how much slope a patio needs?
The standard is 1/8 inch of drop per foot of run (roughly 1% grade). A 12-foot patio needs 1.5 inches of total drop from the house edge to the outer edge. This keeps water moving away from your foundation without being noticeable underfoot. More slope looks uneven; less slope causes pooling.
What is polymeric sand and why does it matter?
Polymeric sand is a blend of fine aggregate and polymer binders that hardens when wet and sets like grout between patio joints. It prevents weed growth, resists ant tunneling, and locks stones from shifting laterally. Standard kiln-dried sand washes out within one season. Polymeric sand properly applied lasts 5–10 years before needing a top-up.
How long after patio installation before you can put furniture on it?
For interlock, furniture can go on immediately — there's no cure time. For poured concrete, wait a minimum of 7 days before furniture and 28 days before heavy loads. For polymeric sand, avoid heavy rain and foot traffic for 24 hours after installation to let the binder set properly.
Will a new patio affect my home's drainage or foundation?
It can — if installed incorrectly. A patio that slopes toward the house rather than away will direct thousands of litres of rainwater toward your foundation each year. We always slope away from structures at minimum 1% grade, and on tight lots we design drainage channels to route water to a safe outlet. This is a non-negotiable part of every installation.
