Retaining Wall Repair & Replacement in North Vancouver
On the North Shore's slopes, retaining walls do quiet, critical work — holding back the ground that your yard, driveway, and sometimes your home sit on. When one starts to lean or crack, it's telling you something. Here's how to read it and what a proper repair takes.
Why retaining walls fail on the North Shore
Our terrain and rainfall are hard on retaining walls. The usual culprit isn't the wall itself — it's water. When drainage behind a wall fails, saturated soil pushes with enormous force, and the wall leans, bulges, cracks, or slides. Other causes include an original wall that was undersized or unengineered, footings that were too shallow, and roots or erosion. Age plus water is the classic North Shore combination.
Reading the warning signs
A wall that is leaning or tilting forward, bulging in the middle, developing horizontal or stair-step cracks, separating at corners, or letting soil and water escape through it is under more pressure than it was built for. Ground settling or cracking above the wall, or a driveway or patio pulling away from it, are related signs. None of these fix themselves — they progress, and a wall that fails can take a slope, a driveway, or worse with it.
Repair or replace?
It depends on why it's failing and how far it's gone. A structurally sound wall with a drainage problem can often be saved by correcting the drainage and making targeted repairs. A wall that was never engineered for its load, or that has moved significantly, usually needs to be rebuilt properly — correctly sized, reinforced, and drained. We assess the cause first and give you an honest answer, not an automatic 'tear it down.'
Drainage is the real repair
Rebuilding a wall without fixing why the last one failed just resets the clock. A proper retaining wall repair addresses the water: drainage rock, weep holes or perforated drain pipe behind the wall, and grading that moves water away. Get the drainage right and the wall lasts; ignore it and even a beautiful new wall is on borrowed time. This is the part cheap jobs skip.
Engineering and permits for bigger walls
Taller and load-bearing retaining walls — especially those holding up a driveway, a structure, or a significant slope — typically require engineering and a permit on the North Shore. That's protection: the wall is designed for the actual soil loads and inspected. We coordinate the engineering and permitting for walls that need it, and build them to last on ground that tests them.
