Grey Block Retaining Walls

When it comes to making the most of your available space, homeowners and landscape contractors agree that grey block retaining walls can be an affordable and reliable solution. As we stock a wide range of grey blocks, chances are good that we’ll have the perfect block for you to build yourself a retaining wall.

If constructed in the proper manner, grey block retaining walls can add style and value to any outdoor area.

Grey block retaining walls are also available in a “dry stack” configuration, eliminating the need for jointing, and in some cases , a concrete footing.

  • Ideal for DIY weekend projects
  • Cost effective
  • Long lasting
  • Environmental benefits
  • Can be topped in wood or with cap blocks

While some might say that grey block retaining walls won’t be stylish enough, modern designs and craftsmanship mean that our range of blocks will suit any desired aesthetic. Just look for yourself below:
