The information below is provided to fully understand the considerations when installing a new retaining wall, or replacing an existing retaining wall.

Pressure Treated Timber

Pressure treated 6″ x 6″ timber retaining walls have been installed throughout Vancouver, the Fraser Valley, and Vancouver Island for decades. Correct installation is the KEY to making timber walls last their full lifespan, which is typically 25-30 years. This includes the use of horizontal tiebacks with deadmen (which secure the wall to the earth it is retaining), and effective drainage management. Use of soldier piles can also be incorporated to allow walls to be installed where there is minimal access, or where it is critical that the landscape behind the wall is not damaged.

Biggest Pro
Timber walls are THE MOST cost effective retaining walls		Biggest Con
Timber walls are limited to a 25-30 year lifespan.

Concrete Block

Concrete block retaining walls (the popular Allan Block walls), are the most commonly installed retaining wall system at new construction projects. Not only is it a proven effective method of retaining soil, but it has extreme versatility for conforming to landscape and architectural designs/layouts. It may be considered the most popular retaining wall system of the contemporary world. Concrete block walls also have many color and finish options, which provides great opportunity for an aesthetically pleasing landscape!

PLEASE NOTE: Correct installation is extremely necessary for this wall to last EVEN THOUGH it is concrete. If a gravel base is not packed enough, you will have sinking blocks. If an effective water management system is not put in place, hydrostatic pressure will build after rainfall and collapse an entire wall. Geogrid is the ‘tieback’ system for block walls, and it is primarily required for walls over 4′ high. Walls below 4′ high are typically constructed as gravity walls.

Biggest Pro
Concrete block walls are very versatile and will last a lifetime.
They are the best value for the money.		Biggest Con
Cost is almost double that of timber walls.

Precast Concrete Slab

Precast concrete slab walls are one of the best ways of retaining soil. It is BEST used on long straight runs as it is not as versatile as previously mentioned systems. Precast slab walls are typically cast in manageable sizes, and stacked into steel I-Beam piles. Piles are set in concrete footings and must have a depth equal to the height of the wall. Precast concrete walls are best suited for commercial/new construction applications. Gravels and drainage is still a necessity, and this style of wall has a plastic sheeting on the backside, to avoid leaking/water stains through the front face.

Biggest Pro
Mid-range cost, between timber and concrete block.		Biggest Con
Not as versatile as other options. Best suited on large projects.

The Process

If you have retaining walls that need replacement, or if you need retaining walls you first need to determine the height of the new walls. If they are going to be over 4′ high, it is necessary to contact a Geo Technical Engineer, who will provide engineered drawings of the wall design, installation process and any special requirements for your specific geographical area.

If the walls are below 4′ high – CONTACT US

If the walls are above 4′ high – Reach out to a Geo Technical Engineering company for guidance and drawings.

CONTACT US AS SOON AS YOU HAVE THE DRAWINGS.

If you have space to TERRACE the wall with segments no greater than 4′ high – CONTACT US
