401 CRT Construction Inc. pours driveways, walkways, patios, and interlocking that hold their line for decades — engineered specs, honest quotes, no shortcuts on the base.
401 CRT Construction Inc. is a concrete, interlocking, landscaping, decking, and renovation contractor based in the Guelph/Kitchener area, serving homeowners and property managers across Waterloo Region and beyond.
We run every job the same way: a proper site visit, an itemized written quote, a compacted base done to spec, and a finish that holds up through Ontario winters — not just the first season. No verbal estimates, no cutting corners on the gravel base, no disappearing after the pour.
Our team brings hands-on trade experience together with formal training in electrical systems and business management, so projects are run with both technical precision and clear communication from quote to sign-off.
Technical grounding for wiring, lighting & power on reno projects.
Clear contracts, staged payments, and organized project tracking.
Driveways, patios, walkways — base-up, done to municipal spec.

"Add a second testimonial here — mention timeline, communication, or quality of finish."
"Add a third testimonial here — a renovation or landscaping client works well for variety."
From a single sidewalk pour to a complete backyard rebuild — one crew, one contract, one standard.
Full-depth gravel base, mesh or rebar reinforcement, broom or exposed-aggregate finish, saw-cut control joints.
Poured or interlock walkways and entrance steps, built to grade with proper drainage and expansion strips.
Patios, driveways, and borders in a full range of paver styles — compacted base, polymeric sand, edge restraint.
Structural retaining walls, garden beds, sod, and grading — built to manage water, not fight it.
Custom platform and wrap-around decks, framed to code, finished with your choice of composite or wood.
Basement, framing, electrical, plumbing, and finishing work for secondary units and full home renovations.
Concrete, interlocking & landscaping, and renovation — each run with the same written specs and staged payment structure.
We measure on-site and send an itemized quote — materials, specs, and timeline, no vague line items.
Excavation, compacted gravel base, forming, mesh or rebar — the part that decides if it lasts.
Concrete poured to spec, finished to your choice — broom, exposed aggregate, or stamped — and saw-cut for control joints.
Final walkthrough, care instructions, and your invoice — 40/40/20, no surprises at the end.
Every quote breaks down materials, thickness, and finish — before you commit to anything.
Proper gravel depth and compaction on every job — the step that gets skipped elsewhere.
Based in the Guelph/Kitchener area — we're around long after the truck leaves.
A 40/40/20 schedule tied to milestones, not a deposit that disappears.
This is the baseline we build to on driveways, walkways, and slabs — adjusted per project after a site visit.
