Why is the base work important for retaining walls?

Why is the base work important for retaining walls?

Just like concrete and asphalt, the basing supports the structure.


Walls are held together by gravity, pins or lip systems, depending on the material you choose for building your retaining wall.

Retaining walls are made to be floating walls, meaning they move as the ground moves. The better the foundation supporting your wall, the better chance you have of minimizing the movement in your wall. In addition to the basing work, making sure you have a good drainage system in place is very important as well. Water building up behind the wall with nowhere to go just pushes against the back of the wall causing it to push out and even sometime tip over.

  • Excavate & Base

    During the basing phase, it is also the time to develop a drainage plan that dos not leave you with puddles of water or a drainage plan allowing water to flow towards your house or garage.

    We will take the extra step on projects which have drainage issues to shoot elevations and work with the homeowner to make sure the best drainage possible is set before we install asphalt or concrete.
