Large Block Retaining Wall Construction

When you have a need for a very large retaining wall to hold back earth you need to start looking at much larger retaining wall blocks in order to speed up installation and ultimately lower labor costs as these large scale walls can get expensive quickly.  There are a variety of large format retaining walls products on the market including natural boulders and concrete pre-cast retaining wall blocks.  Both options can work very well when installed properly but the pre-cast, pre-engineered block systems have several advantages over a natural boulder wall.

Alan’s Landscaping and Heather’s Gardens (Shade Group for short!) is a family owned and operated landscape design and construction company based out of Ottawa.  We specialize in the design and construction of large format or block retaining walls using M Con products "Stone Strong" blocks.  These large format pre-cast concrete blocks come in a variety of different colors and styles and are specifically engineered to be lighter than solid concrete blocks and bigger than other concrete block wall products. Their lighter weight, increased size, and interlocking system help reduce overall labour costs and installation time for especially large wall projects.

Large Block Retaining Walls Are Great For:

  • Residential projects requiring large walls
  • Commercial projects requiring large walls
  • Seawalls or lakefront walls
  • Walling the edges of roads or driveways against a slope
  • Retaining walls with heavy surcharges such as carving out space for parking areas for boats, RV's, and vehicles

We have the knowledge, expertise and access to the heavy equipment to construct large format block retaining walls for a variety of different uses.

Retaining Walls & Building Permits in Ottawa

According to the Ottawa building codes a “retaining wall” means a structure which supports and confines a mass of earth or water where there is a change in ground elevation. Retaining walls that are over 1.2 meters (3.9ft) in height will usually require a building permit. In addition any retaining walls over 1.2 meters (3.9ft) in height must be designed and signed off by a geo-technical and/or structural engineer to ensure the wall is properly constructed for your site conditions and intended purpose (like a surcharge load). This does not account for any covenants that might be on your property.

How Our Retaining Wall Construction Process Works

When building a retaining wall on your property that is designed to hold back tonnes of soil and earth there is very little margin for error. Depending on how large your retaining wall and what purpose it is intended to serve, we may need to work directly with a geotechnical engineer to ensure your wall is built the right way.

  1. We start with our initial consultation.
  2. We determine how many feet of retaining wall you need.
  3. We determine the height of the wall and if a building permit or engineer will be required.
  4. We consult with you on the type of look you'd like the finished project to have (e.g. colour, texture, stamped, etc.).
  5. We’ll provide you with an accurate written estimate for the work.
  6. We’ll get to work on the schedule start-date and build your new retaining wall.
  7. We'll maintain open and transparent lines of communication throughout the project, including daily updates on how things are progressing. We believe communication is important and vital to a succesful project!
  8. The end result will be a beautiful new retaining wall on your property.

The amount of work required to build a retaining wall can vary widely from project to project. The slope of your property, the amount of earth your retaining wall must hold back and the overall accessibility of your property will all contribute to the final cost.

Remember:  Retaining walls that are in excess of 1.2 meters in height (3.9 ft) will require a building permit and must be designed by a geotechnical engineer.  We are more than happy to arrange and organize  more complex projects such as this.
