Retaining Walls
Don’t let your retaining wall become a dam
Concrete block or natural stone?
We have the expertise and equipment to build any type of retaining wall from natural stone to large concrete blocks. Our walls are built using pre-engineered blocks and designed to last. It’s important to note that blocks are rated for specific heights. Exceeding this rating can lead to instability. we can also be customized to include steps, if needed. We work with a variety of materials, including limestone, granite, boulders, and concrete block.
Retaining walls along side driveways can be tricky because you have the added weight of vehicles. If the wall is above a driveway it could be hit by plows or damaged from water run off. It’s usally best to have a buffer area between a driveway and the neighbouring wall to allow for drainage and the area can be used to stage plants or shrubs. It’s best to find a contractor that can spot potential problems areas and can provide alternative solutions to these situations.
Waterfront breakwalls
If you’re planning a waterfront project, we can help. With extensive experience collaborating with the Mattawa Conservation Authority, we actively assist in securing the necessary permits for your project. We have a diverse range of natural stone options for break walls on waterfront properties. Natural stone is a pricer option but a requirement when dealing with water. Nothing last longer in water than a piece of the Canadian shield.
In areas with harsh freeze-thaw cycles like northern Ontario, using the proper blocks is essential to ensure the retaining wall remains sturdy. If there is clay present then the use of a ridge foam insulation may be required to prevent frost heaving. Our walls include an extra-wide base, geogrid reinforcement every second course to tie these rows back into the existing slope. We also use a geo-textile fabric in the sub-base to ensure minimal settle and maximum stability.
Backfilling and water drainage
Backfilling is also crucial when building a retaining wall. Using a material that won’t hold water is important. Retaining walls that hold back water can fail due to the extra weight created by water damming. Knowing whether you’ll require drainage tile behind the wall or an outdoor sump pit for excessive water issues is crucial. Improper construction could be the cause if you’re experiencing issues with your retaining wall, such as leaning or pushing out. Don’t hesitate to contact NorthStead for assistance.
