What is a retaining wall?

The purpose of a retaining wall is in the name. But what exactly is this wall retaining?

Retaining walls are generally used on lands that have slopes, they are used to effectively remove the slope, creating a wall in-between, which can vary in size from a metre, to a few feet!

Without retaining walls, a sloped area of land can be a health hazard in public areas and some gardens. In the case of a garden, a slope can make it an inconvenience to navigate.

Drainage for retaining walls

All retaining walls should have drainage. Drainage is typically located at the bottom of the retaining wall. It comes in the form of a pipe layered below gravel or other landscape fill, which itself is below the topsoil of the slope the retaining wall was made for.

As rain falls upon the soil, it travels through it, it then travels through the gravel, until it reaches the pipe and drains to the exit that the pipe directs it to. Without drainage, retaining walls will be under a greater amount of weight provided by the rain, in addition to the weight already being supported by the retaining wall.

What makes a bad retaining wall?

A bad retaining wall is one which can not support the area it was designed to. There are the signs of a badly constructed retaining wall.

How to build a garden retaining wall with Interlocking Concrete Blocks

A garden retaining wall helps organise gardens that contain slopes. Aside from aesthetic purposes, it can also practically help by organising your garden into different areas. This is especially handy for horticulture enthusiasts, or those who want to use the extra space for a shed, or other installation. 

Retaining walls can be built with materials such as steel and wood, though the easiest, and fastest method is through using Interlocking Concrete Blocks. Here is a very brief step by step of how to build a retaining wall with Interlocking Concrete Blocks.

*Prior to this, make sure you have your measurements for the height of the wall, in addition to measurements for drainage, and footings. Footings are required for retaining walls to create a solid foundation for the wall itself, neglecting your footings will result in your wall changing shape over time. With that out of the way, here are the next steps.

  1. Dig the area that the retaining wall will be erected, this depth will be dependent on your footings. Using a mini digger will expedite this process.
  2. Once dug, make an additional measurement to ensure you have dug to the correct depth before installing your Interlocking Concrete Blocks.
  3. If your blocks have already been delivered, obtain the relevant heavy lifting equipment to place your foundational blocks and begin placement, making sure there is space for drainage.
  4. Repeat this process, making sure to stack the blocks so that the studs and recesses connect. Do this until you have reached your desired height.

*Please use this guide to gain an understanding of the process of how to build a garden retaining wall with Interlocking Concrete Blocks. It is best to contact a local landscaping professional for guidance concerning your garden specifically.

What Is the Difference Between Concrete Block and Masonry Block?

Do Interlocking Concrete Blocks need glue or cement?

No, our Interlocking Concrete Blocks require no form of binding at all. They are held together by the studs and recesses at the top and bottom of each block. They are connected by placing the blocks on top of each other.

What can dislodge Interlocking Concrete Blocks?

Interlocking Concrete Blocks can be dislodged by lifting the block from the stud it was placed on. This gives Interlocking Concrete Blocks a chance to be reused should that be required. 

Aside from that, there is no natural means that Interlocking Concrete Blocks can be dislodged aside from a natural disaster, or having no drainage or footings.
