The nightmare of Quebec landlords

Every spring, thousands of Quebec homeowners are shocked to discover that their retaining walls have sunk, cracked, or completely collapsed over the winter. This phenomenon, far from being isolated, represents a recurring problem that is costly for homeowners. But why are Quebec winters so devastating to poorly constructed block walls? The answer lies in a deadly combination of freezing, thawing, and accumulated water. Duvernay Asphalte.We have long understood that the construction of a low wall made of blocks Sustainable construction in Quebec requires much more than just traditional masonry skills.

The freeze-thaw cycles characteristic of our climate create considerable pressure on outdoor structures. Water that seeps into microscopic cracks freezes, expands, and exerts a force capable of moving tons of concrete. Without a solid foundation and one drainage adequate, even the most beautiful low wall made of blocks will eventually give way under these repeated assaults.

The fatal mistakes that will doom your low wall

The lack of an adequate foundation

The first mistake made by many installers is to install the blocs talus built directly on the ground, without digging a proper foundation. This practice, while economical in the short term, inevitably dooms the retaining wall. Quebec soil, particularly clayey in several regions, swells and contracts with the seasons. According to the Régie du bâtiment du Québec (Quebec Building Authority), clay soils are highly compressible and can undergo volume changes during climatic shifts such as periods of drought. Without a base set below the frost line, generally about 1.2 to 1.5 meters deep in our region, soil movements are transmitted directly to the structure.

A solid foundation for a retaining wall It must rest on a bed of compacted crushed stone, itself installed in a sufficiently sized excavation. This drainage base absorbs soil movement while allowing water to flow freely. Duvernay Asphalte.We have mastered this fundamental technique which distinguishes our installations from hasty constructions.

Drainage: the great forgotten element

Water is the number one enemy of everything low wall made of blocksHowever, drainage is frequently neglected during installation. Behind a retaining wall, hydrostatic pressure can reach hundreds of kilograms per square meter. This pressure, amplified by the freezing of water retained in the soil, gradually pushes the blocks outwards until the structure collapses.

The Quebec Construction Code requires that the base of exterior foundation walls be drained using pipes or drains installed outside the foundation. An effective drainage system must include several essential elements: a drainage geotextile membrane applied to the wall, a perforated drainage pipe collecting water at the base of the wall, and a layer of crushed stone allowing this water to flow to a discharge point away from the structure. This multi-layered approach ensures that water never stagnates behind the wall. low wall made of blocks, thus eliminating the risk of destructive hydrostatic pressure.

The quality of the materials

All the blocs talus They are not all created equal. The market offers a wide range of products whose quality varies considerably. Lower-quality blocks absorb more water, making them vulnerable to frost damage. Furthermore, their compressive strength may be insufficient for retaining wall applications.

Duvernay Asphalte. We exclusively select blocks that meet the strictest industry standards. Our suppliers are carefully chosen for the consistent quality of their products and the reliability of their certifications. This rigorous approach to material selection, combined with installation adhering to best practices, ensures the sustainability of each projectlandscaping that we are realizing.

The secrets of a sustainable installation

Preparing the ground

Before even laying the first block, a thorough site analysis is essential. The soil type, its composition, permeability, and the possible presence of groundwater determine the installation's technical specifications. Clay soil will require different measures than sandy soil. The proximity of trees whose roots could disturb the structure must also be assessed, because, as experts point out, trees can cause ground movement that affects foundations.

At Duvernay Asphalte.Our team systematically conducts this preliminary assessment. This proactive approach allows us to anticipate the specific challenges of each site and adapt our installation method accordingly. It is this attention to detail that guarantees the sustainability of us low walls made of blocks faced with the rigors of the Quebec climate.

Alignment and leveling

And retaining wall A poorly aligned or uneven wall is doomed. Each block must be perfectly level both lengthwise and crosswise. The slightest misalignment will have repercussions and amplify throughout the installation, creating structural weaknesses.

Our technicians use precision instruments to constantly check alignment and leveling. Each block is individually adjusted before the next is laid. This meticulous work, while more time-consuming and requiring expertise, produces impeccable results that withstand the test of time and the harshest winters.

The locking system

THE blocs talus Modern concrete block walls are designed with an interlocking system that ensures overall stability. However, this system is only effective if each row is correctly positioned according to the manufacturer's specifications. Failure to follow these guidelines compromises the wall's structural integrity. According to building experts, concrete block walls are susceptible to lateral soil pressure and can easily lose their structural integrity if the loads are not properly accounted for.

Our team has mastered the installation techniques recommended by block manufacturers. We use special connectors and integrated drainage systems that reinforce the structure while allowing water to escape. This dual function—mechanical support and water management—is the hallmark of our expertise in the field of low wall made of blocks.

“I had a retaining wall installed by another contractor three years ago. This winter, it literally collapsed after the first few weeks of frost. The Duvernay Asphalte team completely redid my landscaping with block walls. I was impressed by their professionalism and attention to detail. The result is not only beautiful, but I know it will last for decades.” — Satisfied customer
