Completely change the look of your yard

Your home and yard are important to you, and you want to create more space to entertain family and friends.

When you replace your existing wood retaining wall you completely transform the look of your property.

If you choose to add a terrace between walls you will create an ideal space for plants, and birds.

Because of its height, depth, and color your new retaining wall will be a focal point in your new space.

These are some of the most common purposes, and features of your retaining wall:

Confidence in your project

When planning for your retaining wall build, there are many unknowns. You have never taken on a project like this, and you are not sure who can build one. What you do know is that you want a wall that not only looks great, but will last.

Whether your retaining wall is large or small, your wall needs to be built to Allan Block specifications. Failing walls do not have drainage, the proper depth of excavation, or enough gravel behind them.

Back40Landscaping’s staff are trained and certified by Allan Block, with ongoing training from Allan Block professionals after every single retaining wall build.

Trust that when a wall is built to Allan Block best practices you can focus on what flowers and plants to put in your garden, and planning what to grill for tonight’s get together, instead of wondering when your wall will fail.

From the moment Back40 started my perimeter drainage and retaining wall project, I could see Sam and Victor’s dedication. 

They arrived early and stayed late; one day I came home and Victor was still filling Allan Blocks at 19:00 on a Friday because he wanted to finish the first row (now, that is commitment!).

Despite the endless water and excavation, Sam continued to strive to find the solution when many would have given up. 

I found comfort knowing that he would continue to explore his options until he found a solution he had confidence in. 

Back40 has transformed my backyard into an oasis for years to come. 

They will definitely be back to attack the front retaining walls once I have restocked the renovation fund 😉

I am very happy with the experience and the final product of our project with Back40 Landscaping. 

My project included a two-tier Allan Block retaining wall, large interlocking brick patio, walkways, and driveway. All looks amazing! 

Sam and Andrew were efficient, skillful, and made sure to ‘do it right’. They built to, or exceeded, Code with everything they built and they were very thoughtful of the workplace. 

They were careful of where they staged their equipment and materials to minimize impact for myself and my neighbours. 

After every shift, they cleaned up behind themselves going so far as to sweep the street if needed. 

Very impressed and can’t recommend them enough!

Sam and his crew from Back 40 Landscaping replaced a rotten and fallen wooden retaining wall with a beautiful Allan Block wall. 

I found everyone to be very polite, courteous and extremely professional. 

They all worked hard and took pride in their work. 

Sam was meticulous placing each Allan block. He strove for perfection and the finished wall exceeded my expectations. 

Sam and Natasha were wonderful and helped to make this a great experience. 

Thank you to everyone at Back 40 Landscaping for my beautiful new wall!
