Vancouver's climate, which provides for period of heavy rains, provides challenges to engineer lasting retaining walls. During winter months, constant relative humidity conditions of near 100% - in addition to an average of over five feet of rain annually – can create serious issues for retaining walls. Saturated soils are often 3 to 4 times heavier than dry soils and thus demand far more structural integrity of retaining walls. Timber retaining walls, while less expensive, also tend to have a shorter life expectancy in this climate than in drier climates. Landesign provides engineered retaining walls to meet the structural needs of your property and desired elevations. The aesthetic component of retaining walls is not over looked, as we can help you to choose the right material and the right elevations and placement to maximize the shape, liveability and appeal of your garden.
