Interlocking driveways, walkways & patios
Interlock built on a base that will not settle — driveways, walkways, patios, steps and retaining walls, installed by the same crew that does your paving and grading.
Interlock fails at the base and the edges
A sunken interlock walkway is almost never a stone problem. It is an under-compacted base, the wrong bedding material, or a missing edge restraint that let the outside course wander. We build to a compacted granular depth appropriate to the load — deeper under a driveway than under a patio — with proper bedding and polymeric jointing.
Because we already own the excavation and compaction equipment for paving, the base under our interlock is built the same way we build a road base.
We work in Unilock, Techo-Bloc and Permacon product lines, and we will show you finished installations nearby before you commit to a colour.
What's included
How the job runs, step by step
Design & product
Layout, pattern, colour and product selected — and we will show you finished installations nearby before you commit.
Excavate & base
Excavation to a depth set by the use, then compacted granular in lifts. Deeper under vehicles than under a patio.
Bedding & lay
Screeded bedding course, stone laid to pattern, cuts made clean at edges and around fixtures.
Restrain & joint
Edge restraint on every open edge, polymeric sand swept and set, surface compacted and washed down.
Why interlock settles, and how we prevent it
Base depth to match the use
A patio base under a driveway will rut. Vehicle areas get depth and compaction closer to a road base.
Edge restraint everywhere
Without restraint the outer courses spread, joints open and the whole field loses its lock.
Correct bedding layer
A screeded bedding course of the right material — not a thick sand cushion, which washes and settles.
Polymeric jointing
Locks the joints, resists washout and slows weed growth. Ordinary sand does none of that for long.
Driveway-grade pavers
Thin patio stone cracks under a car. The paver spec has to match the load.
Water managed off the surface
Interlock is not a drainage solution. Water still has to be graded away, or it will find the joints.
Interlocking questions
How long does interlock last?
Thirty years or more when the base is right. The pavers themselves outlast the base, which is why installation quality decides the lifespan. Expect to re-sand joints every few years and re-level a section or two over that period.
Can interlock handle a car?
Yes, with driveway-grade pavers and a deeper compacted base than a patio needs. Thin patio stone under vehicle loading will crack and rut, so the paver spec and base depth have to match the use.
Why are weeds growing in my joints?
Weeds grow in the joint sand from seed landing on top, not from below. Polymeric sand and periodic re-sanding fix most of it. If whole joints have washed out, water is running across the surface and the grade needs attention.
