What do retaining walls do?

What do retaining walls do?

Retaining walls serve to organise a piece of land that is sloped or on a hill. Its organisation can come in the form of digging and creating a structure that ‘retains’ the land behind it. THe size of the retaining wall can be small or large, and can serve to make way for additional features such as safe paths, stairs, seating areas and more.

Without retaining walls, it would be harder to safely traverse across some areas, especially those at risk of landslides. The hills that a retaining wall replaces is also a health hazard for anyone on it, especially in bad weather conditions. This causes a problem in public places such as parks, or even in your own back garden.

Do I need a retaining wall?

If you find yourself identifying with the following points, you may need to consider a retaining wall.

  • Your garden or land you own has a hill that is dangerous or slippery.
  • The hills in your land or garden makes it difficult to use the garden or organise it.
  • The uneven state of your land or in your garden means you can’t plant flowers or vegetables, or build there.
  • Your children or guests can’t freely use the garden due to the uneven floor.
  • Rain pools into the deeper levels of your garden or land

–       Somewhat durable.

–       Generally doesn’t require heavy lifting equipment.

–       Can break with a high velocity impact.

–       Weather resistance must be amplified.

Our Interlocking Concrete Blocks can be used in the construction of retaining walls. They are a reliable and durable form of pre-cast concrete blocks. Featuring a unique interlocking feature, this provides not only a heavyweight reinforced structure, but also the ability to be used as a wall without binding elements such as cement.

This makes it a perfect, relatively quick and simple to install alternative to traditional brick or wooden retaining walls. The durable heavyweight nature of these concrete blocks enable them to stand the test of time, and stand the collective weight of the land it is holding behind it. Once interlocked, this potential only increases.

There are many advantages of Interlocking Concrete Blocks, one of which being their multiple methods of application, they can be used for a variety of projects.

Is it worth using wood for a retaining wall?

If you know what you’re doing, it can be worth using wood for the construction of your retaining wall. Especially if you want a much more bespoke design, although this comes with compromising against the structural integrity, durability, and longevity that is provided by a concrete retaining wall.

Concrete retaining walls can feature bespoke designs too, but would require a specialist which will definitely end up costing more.

Can water affect a wooden retaining wall?

If the wood waterproofed, and the drainage system of the retaining wall is not properly constructed, water will affect a wooden retaining wall in the one, many of the following ways.

  • The wood can rot over time
  • The wood can break
  • The wall can become slanted due to the weakening of the wood, and the pull of gravity on the retained soil behind the wall.
  • It has the potential to house mould or fungus.

Additionally, fire can destroy your wooden retaining wall, and has a limited durability, when put up against a concrete retaining wall, which doesn’t suffer from any of those issues. Consequently, concrete is the superior material for a retaining wall.
