Product Choice

Opt for products aligning with both your budget and aesthetic preferences. Also keep in mind functionality – what do you want from your retaining wall block? Do you need something for dual purpose? It’s important to consider every aspect before choosing your product.

Handling and installation

You need to consider how you intend to handle and install concrete sleepers as they tend to be around 2 metres or more and can weigh as much as a person. Concrete sleepers and cement sleepers require multiple people to handle and install them because they are difficult and heavy to manoeuvre.

Retaining wall blocks are much easier to use, only requires one person to handle and install which makes the job easier.
