Choosing your blocks
Choose what grade of block you order carefully as the different characteristics of each grade can affect how your wall should be built (more info about each grade is on our A-Grade and B-Grade pages).
The most important thing is to create a solid foundation to ensure your blocks don’t compromise the wall’s structural integrity by shifting. Each case can vary depending on the site. Firstly, It would depend on the composition of the “natural ground” where the blocks are being laid. If it is a basic soil/clay, etc. foundation, and especially with ground water running behind, then we suggest using a compacted road base at a minimum to help stabilise the footing.
Ensure your wall has proper drainage to stop water from collecting and increasing the weight of the earth behind it, therefore increasing the pressure and compromising the structural integrity.
Plan your tiers
For multi-level walls, ensure you plan each tier properly so that the top tiers don’t add too much pressure to the bottom tears.
