Retaining Wall & Hardscaping Services
Engineered Retaining Walls & Hardscaping That Hold
CanaCore coordinates verified crews to build engineered retaining walls and hardscaping — proper footings, drainage, and reinforcement that control erosion and turn slopes into usable yard space, with CanaCore field supervision throughout.
Professional Retaining Wall Construction
Retaining walls hold back soil on slopes, prevent erosion, create usable terraced areas, and add architectural interest to landscapes. Proper construction requires engineering knowledge, quality materials, and correct drainage installation. Our experienced crews build walls that last—proper footing below frost line, perforated drainage pipe behind walls, geogrid reinforcement when needed, and precise construction techniques that ensure stability for decades.

Common questions
Does a retaining wall need engineering?
Above a certain height it does, and the threshold is set by your municipality. Low garden walls generally do not, but anything holding back a meaningful slope, or supporting a driveway or structure above, should be engineered and prepared for permit review.
Why do retaining walls fail or lean over time?
Almost always water and drainage — pressure builds up behind a wall that cannot drain, and it pushes the wall out. Proper drainage, backfill and a sound base are what keep it standing, which is why the part behind the wall matters as much as the face.
What goes behind a retaining wall besides the blocks?
A compacted base, free-draining backfill and drainage to relieve water pressure, and reinforcement where the height calls for it. The visible stone or block is the smaller part of the job; the base and drainage are what determine whether it lasts.
