Interlocking FAQ
How much does interlocking cost per square foot?
$25 to $40 per square foot installed in Toronto and the GTA, before HST. Patios sit at the lower end, driveways and walkways with removal at the upper end.
How long does interlock last?
Pavers themselves last 30-plus years. A properly built base lasts as long. Most failures people see are base failures within 3 to 5 years of a cheap install.
What base do you use?
Granular A (3/4-inch crushed limestone) compacted in 3-inch lifts: 6 to 8 inches for patios and walkways, 10 to 12 inches for driveways. Geotextile fabric goes under the base on clay soils. A 1-inch screeded bedding layer of coarse sand or HPB sits on top.
When is the best time to install interlock in Ontario?
April through November, as long as the ground is not frozen. Spring books up first; late summer and fall often have shorter waits and the same quality.
Do I need a permit?
Ground-level patios and walkways usually do not. Retaining walls over 1 m, raised patios and some driveway widenings do. We check your municipality's rules at the estimate.
What is polymeric sand?
Joint sand mixed with a binder that hardens when wetted. It locks the pavers, resists weeds and ants, and does not wash out like plain sand. We use it on every job.
Should I seal my interlock?
Optional. Sealing every 3 to 5 years keeps colour, slows weeds and makes cleaning easier. We offer clean-and-seal as a service.
Can you build on a slope?
Yes. We terrace with segmental retaining walls and steps, with proper drainage behind every wall.
Is interlock slippery in winter?
No more than concrete. Textured pavers and slabs are actually better grip than smooth concrete. Use salt-free ice melt to protect the surface.
What about weeds and ants?
Polymeric sand joints and a proper edge restraint stop most of it. Old sand-set interlock gets weeds because the joints are open soil.
