Above-Ground Swimming Pool Base for Slopes 4.125 x 4.125 x 0.65m

Transform your garden slope into the perfect spot for an above-ground swimming pool! Whatever your pool size, this clever kit can be customised to your exact needs - just use our Free Design Service

Designed to level a sloping area by building up on one side, this low retaining wall kit has internal buttresses that make it super strong. There’s minimal digging required to install your pool base too, just follow the layer by layer instructions and backfill with suitable material as you build. This kit builds the SURROUND ONLY - you will need to source suitable infill.

If you are looking to create an above-ground pool base using the reverse ‘dig-out’ method where you’ll need to cut away into the slope, WoodBlocX retaining walls can be used for that too! Contact us with your measurements and we’ll design you a retaining wall that works for your garden project. 

Our pressure-treated timber and unique interlocking dowel system ensure this pool base for slopes will be durable for many years to come. There’s no power tools or cutting required when building this retaining wall, a lump hammer is all you need!  

This pool base retaining wall kit is 4.125m long x 4.125m wide x 0.65m high at the tallest end reducing down to 0.25m where it meets the slope. Design your own size using our Free Design Service

PLEASE NOTE: Swimming pool, infill and grass are not included. This kit includes the components to build a wooden C-shaped retaining wall only.

Do you require a protective liner? (+£30) ?

To maximise the lifespan of your structure we strongly recommend you install a protective liner to provide a damp-proof barrier between WoodBlocX timber and soil. Learn about how to install a liner.

When you select ‘Yes’ on this option your kit will include 1 x liner per structure (4 x 5 metres, 20m2) which is made from 100% recycled plastic and costs an additional £30.

When ordering multiple raised beds with the same dimensions, if you select 'Yes' on this option, each kit will include a liner i.e Qty x 2 = 2 liners included.  

Alternatively, to choose your own quantity of liner, you can add Protective Liners individually to your order.
