Local Service in Ajax
Our office is in Markham, and our crews work in Ajax daily. From Salem Heights and Deer Creek to the established central neighborhoods, we design projects specifically for Ajax’s flat terrain, focusing on water management and side-yard utility.
The Ajax Challenge: Flat-Lot Drainage
Ajax is characterized by level ground. While this is ideal for walking, it makes water management difficult.
- The Problem: On a flat lot, water does not move naturally. Rain and snowmelt often sit on the surface, creating standing water near the garage or the base of the steps. This leads to ice buildup in the winter and moss growth in the summer.
- The Solution: We treat drainage as an engineering requirement. We use laser levels to create a 2% slope on every project. This ensures that water is forced away from your foundation and moves toward the street or your soft-scape gardens.
How we build driveways and walkways in Ajax
Because Ajax is so flat, the difference between a good installation and a frustrating one is often just a few degrees of slope and how well edges are controlled. On typical projects, we:
- Remove existing asphalt or concrete and re‑shape the subgrade so there are no hidden pockets where water can sit.
- Install and compact the base in thin layers, checking pitch toward the street or designated drainage points.
- Use robust edge restraints with tight spike spacing along driveway‑adjacent walkways and long runs to keep everything aligned.
- Tie steps, landings and side paths into one continuous design so you’re not stepping up and down unnecessarily, or crossing awkward joints.
Whether the focus is the main driveway, a new approach to the front door, or a long path to the backyard, we build all of it to live on a flat lot without creating new drainage problems.

The Law: The Driveway-Adjacent Walkway Advantage
Ajax municipal rules distinguish between “driveway width” and “adjacent walkways.”
- The 1.8m Rule: In many cases, Ajax allows for a walkway up to 1.8m wide to run alongside your driveway without it counting as an illegal widening.
- Practical Use: We use this exemption to provide legal grounds for moving garbage bins, kids’ bikes, and outdoor gear.
- Construction: We build these walkways on the same reinforced base as the driveway, ensuring they stay level and aligned with the main drive over time.
Typical Investment in Ajax
Prices include excavation, disposal, reinforced base, materials, and labour.
- Standard 2-Car Replacement: $9,000 – $14,500. Focuses on correcting the slope and base for a level lot.
- Driveway + 1.8m Side Walkway: $11,500 – $16,500. Provides maximum legal parking and utility width.
- Front Entrance & Steps: $4,000 – $9,000. Replaces builder concrete with graded stone landings.
- Side & Rear Connection Paths: $3,000 – $7,000. Depends on the length of the run and the machinery access.
Factors that affect price: The amount of re-grading required to fix drainage and the total length of the edge restraints for long walkway runs.
Frequently Asked Questions
My driveway looks flat but still has ice patches. Can interlocking really fix that?
The key is not the stone, but the grading under it. When we rebuild the base with precise pitch, we can direct meltwater to the street or lawn instead of letting it sit in invisible dips.
What is a driveway‑adjacent walkway, and why would I want one in Ajax?
It’s a full‑strength interlocking path running along one side of your driveway, ideal for bins, side‑door access and kids’ gear. It often fits within local rules differently from a full-width increase.
Can you just do the walkway now and the driveway later?
Yes, we can phase the work. We’ll design both at once, so today’s walkway lines up perfectly when you’re ready to redo the driveway.
Will the new walkway stay level next to the driveway over time?
We build driveway‑adjacent paths on the same base standard as the drive, with strong edge restraints and tight spike spacing, so both surfaces move together instead of drifting apart.
Do you work in older parts of Ajax as well as new subdivisions?
We do. Older areas often need more base remediation; newer ones tend to focus on drainage and layout. We adjust our approach based on what your lot actually needs.
How much mess should I expect during construction?
There will be some noise and material movement, but we keep sites tidy, manage waste piles, and clean up daily so you can still safely use your paths and entrances where possible.
Let’s talk about your Ajax layout.
On flat Ajax lots, the difference between a frustrating driveway and a reliable one is a few degrees of slope and a smart walkway plan. If you want a driveway‑adjacent path that feels natural and avoids over‑complicating permits, request a site visit, and we’ll show you what your options look like in stone.
