Retaining Walls in Halton Hills
Sloped or uneven property in Halton Hills? O'Connor Contracting designs and builds retaining walls that hold back grade, create usable outdoor space and become a striking feature in their own right. We serve Georgetown, Acton, Glen Williams, Limehouse and Norval — building walls engineered to drain properly and stand solid through Ontario’s freeze-thaw cycle.

Retaining Wall Options We Build in Halton Hills
We match the wall system to your grade, soil and the look you want:
- Armour stone — large natural limestone blocks for a bold, permanent statement
- Segmental block (Unilock & similar) — engineered, geo-grid reinforced walls for taller grade changes
- Natural & flagstone walls — garden and terrace walls that tie into your interlock and planting beds
- Tiered and terraced walls that turn a steep slope into level, usable yard
Engineered to Last — and to Drain
Most failed retaining walls fail for one reason: water. Every Halton Hills wall we build includes a compacted granular base, free-draining backfill, filter fabric and weeping/drainage so hydrostatic pressure never builds behind the wall. Taller walls are reinforced with geo-grid and, where required, built to engineered spec.

Frequently Asked Questions
Do I need a permit for a retaining wall in Halton Hills?
In Halton Hills, retaining walls over 1 metre (about 3 feet) in height, or walls near a property line or right-of-way, typically require a permit. We advise on requirements and can build to engineered specifications when needed.
What is the best retaining wall material?
It depends on the height and look you want. Armour stone is ideal for a natural, permanent statement; segmental block is best for taller, engineered grade changes; natural stone suits garden and terrace walls. We recommend the right system after seeing your site.
How long do your retaining walls last?
A properly based and drained wall built with quality materials will last decades. Our focus on base preparation and drainage is what prevents the leaning and bulging you see in DIY walls.
How much does a retaining wall cost in Halton Hills?
Cost depends on height, length, material and drainage requirements. We provide free, detailed quotes so you can compare options with no surprises.
