Question 1

What is the process for building a retaining wall?

Accepted Answer

Our process is meticulous to ensure longevity. It begins with a site assessment and detailed design plan. Next is excavation and the pouring of steel-reinforced concrete footings below the frost line. Then, our masons construct the wall, course by course, while simultaneously installing a critical drainage system behind it, which includes proper backfill and weep holes to relieve water pressure. The final steps are adding capstones, final grading of the surrounding area for water runoff, and a complete site cleanup. This systematic approach to retaining wall construction guarantees a stable and durable final structure.

Question 2

How do you ensure a wall can handle Burnaby's heavy rain?

Accepted Answer

Managing water is the most critical aspect of building a lasting wall in our climate. We engineer a multi-layered drainage solution for every project. This starts with a perforated drain pipe at the base, embedded in clear-crush gravel. We then backfill the entire area behind the wall with free-draining gravel, separated from the native soil by a geotextile fabric to prevent clogging. Finally, we install weep holes at regular intervals along the base of the wall. This entire system works together to intercept water, relieve hydrostatic pressure, and safely channel it away, which is essential for any successful retaining wall construction in this region.

Question 3

Are your masons insured and BC code compliant?

Accepted Answer

Absolutely. Our entire team is fully covered by WSBC insurance, protecting both our workers and you as the homeowner. We are deeply familiar with the BC Building Code and all local Burnaby municipal regulations pertaining to retaining walls. For any wall designed to be over 1.2 meters (4 feet) in height, we work with a structural engineer to develop certified plans and manage the entire permitting process with the city. This commitment to compliance ensures your retaining wall construction is not only safe and structurally sound but also fully legal and approved.

Question 4

How long does it take to build a retaining wall?

Accepted Answer

The timeline for a retaining wall construction project depends on its size, complexity, and weather conditions. A straightforward residential wall under 50 feet long might take our team 5 to 7 working days from excavation to completion. Larger, more complex projects, especially those requiring engineering and permits, can take 2 to 4 weeks or more. During our initial consultation, we provide a realistic project timeline based on the specifics of your site, ensuring you have a clear expectation of the construction schedule from start to finish.

Question 5

What materials are best for retaining walls in our climate?

Accepted Answer

The best material depends on both aesthetics and structural requirements. Interlocking concrete blocks are a very popular and durable choice, engineered to withstand freeze-thaw cycles and resist moisture. For a more natural look, quarried stone like basalt or granite offers incredible longevity and a classic appearance. We also construct poured concrete walls for modern designs or very high-load applications. We guide you through the pros and cons of each material, ensuring the choice for your retaining wall construction meets both your design vision and the demands of the Burnaby environment.

Question 6

Do I need a permit for a retaining wall in Burnaby?

Accepted Answer

In the City of Burnaby, a building permit is generally required for any retaining wall that is over 1.2 meters (approximately 4 feet) in height at any point along its length. Walls of this size or greater also require plans stamped by a professional engineer. We are very experienced with this process. If your project requires a permit, we handle the coordination with the engineer and the submission to the city on your behalf. For smaller, decorative walls under this height, a permit is typically not needed, but we still build them to the same high structural standards.

Question 7

What are the common causes of retaining wall failure?

Accepted Answer

In our 14 years of experience, the primary cause of failure is improper water management. Without adequate drainage, hydrostatic pressure builds up behind the wall, pushing it outwards until it cracks or collapses. Other common causes we see are inadequate concrete footings that are too shallow or lack rebar reinforcement, leading to settling and shifting. Using the wrong backfill material can also trap water instead of letting it drain. Our professional retaining wall construction process directly addresses and eliminates every one of these potential failure points for a lasting result.

Question 8

Can you repair an existing cracked retaining wall?

Accepted Answer

Yes, we often perform cracked retaining wall repair, but the viability depends on the cause of the damage. Minor cracking or failing mortar joints can sometimes be addressed with repointing or patching. However, if the wall is leaning, bulging, or has major structural cracks, it's usually a sign of a fundamental failure in the drainage or footing. In these severe cases, a simple repair is not a safe long-term solution. We provide an honest assessment; if a repair is feasible we will do it, but if a rebuild is necessary for safety and stability, we will recommend that course of action for your retaining wall construction.
