Hardscaping
Patio Construction & Hardscaping in Ottawa
Patios, walkways and pool decks built to outlast Ottawa winters.
Overview
Hardscaping is the backbone of every outdoor space we build. From the first lift of base material to the final saw cut, our crew installs each stone to a standard you would not see on a typical residential job.
We work exclusively with engineered pavers from Techo-Bloc, Permacon and Unilock and follow ICPI-aligned base depths so the surface stays true through a decade of Ottawa frost cycles. The result is a patio, walkway or pool surround that looks intentional today and twenty years from now.

Client reviews
What clients say about our hardscaping work.
“ALM did a ton of work around my property, inside and out. Lindsey is very pleasant to work with and also efficient. Rob and his team worked hard and did an excellent job in heavy construction and also landscaping. I'll be choosing ALM from now on. It's hard to find honesty, fairness and skill together.”
“We recently used ALM for a reno in our backyard including some structural repair as a result of some pool issues. Lindsey, Rob and team were awesome, organized, and thorough. They corrected everything to the standards that should have been done in the first place, and more. The landscaping looks great too. Highly recommend.”
“ALM is the competition. Caring, knowledgeable, quality work at the best price to fix my patio and sidewalks with the extras, even grass seed for the finishing touches. WOW.”
