How to line your WoodBlocX raised bed (2024)

Ground types and drainage

For WoodBlocX raised beds built on open soil or grass (soft ground), you should add liner to the side walls including buttresses and leave the base of the raised bed open to allow for good drainage. If the soil or grass you are building on is damp, we advise our customers to build the raised bed on a breathable plastic liner to add that extra bit of protection underneath the structure.

To reduce the volume of soil needed, you could add a drainage layer such as hardcore, sand, logs, twigs or stones - this also helps to prevent weeds from growing up from the ground.

For WoodBlocX raised beds built on patios, paving, concrete or tarmac (hard ground) we recommend fully lining the raised bed including across the base and buttresses. This lining method creates the space to hold soil and adding a few pin holes at the bottom can help with drainage if the soil becomes waterlogged.

When building on hard ground, we recommend adding a drainage layer before adding soil, this could be made up of pea-gravel, sand, rubble or small stones (you really can use whatever you have around in your garden!).
