Timber walls are a very DIY-friendly option. Treated pine sleepers are popular as they’re easy to work with and decent value for money. Sleepers are another choice. Dig holes and add vertical supports using sleepers 75mm thick to build your wall. Space the supports every 1.2m for 2.4m long sleepers, and 1.5m for 3m long sleepers. The flat sleepers can be 50mm thick. Set them make sure they’re level then bolt the two together. To finish you off can paint or stain the wall to match your garden or outdoor area.

Concrete blocks

A great DIY alternative for a masonry wall are interlocking cubes that don’t need any mortar. As a bonus the cubes come so once you put the wall there saving you time and money. Dig a footing then put roadbase in compact and the trench it, making sure the level of it. All you do is simply lay out the blocks, as you move locking them together. It’s that easy.

Go natural

To create a feature in your backyard that formal than blocks or wood, use a pure rock such as granite or sandstone. Building the wall is as you try to find pieces of stone that lock 21, similar to performing a jigsaw puzzle that is vertical. Mortar the first stones down then lay a bed of mortar between the rocks as you build it up. Finish off by filling the joints with more mortar, wiping with a sponge for a smooth finish in the front of the stones.


So that it’s important you provide for drainage behind it, significant pressure can be built up by water behind a wall. Lay a a drain and fill above it. Encase the entire lot in fabric, that allows water through but prevents dirt from washing in and clogging up your drain.
