Concrete Retaining Wall Construction
Concrete is a good alternative to a traditional block retaining wall and when planned and built properly can last for decades. Concrete retaining walls can be colored, textured, and accented using concrete stamps or embedded objects to give them a unique look too. In certain situations concrete retaining walls can also cost less to install.

Concrete Retaining Wall Footing Size
Depending on how large the wall is and what it’s holding back the depth of the footing can be adjusted. The depth for the base slab should usually be kept at a minimum of two feet. In a northern climate like Ottawa where we see very cold weather the footing should extend below the frost line. After viewing your property and the site where you’d like the concrete retaining wall built we can provide you with more detailed information about how the wall should be constructed.
Drainage For Concrete Retaining Walls
Because concrete is impermeable (doesn’t allow water through) special considerations must always be made for proper drainage. This is achieved through using proper course stone for the base of the wall, using a courser backfill behind the wall to allow water to drain more easily, and also by the installation of drains or weepholes in the concrete wall itself. Because of the nature of poured concrete walls they can be very susceptible to hydrostatic pressure or lateral pressure from the surcharge (weight) behind the wall. Without proper drainage it’s not uncommon for a concrete retaining wall to crack if the pressure behind the wall becomes too great.
At ALHG we have the knowledge and expertise to build beautiful, functional, concrete retaining walls that will last a lifetime.
