Garden Base Kit With Base Panels, Membrane & Pins - Covers 5x4ft (20ft²)
Suitable for use under garden buildings with a footprint of up to 5ft x 4ft, or multiple can be connected together as part of a larger base.
Our plastic garden base panels are the perfect alternative to traditional concrete or wood bases. Manufactured from a highly durable recycled plastic, our strong, easy-to-install, weatherproof and rot-free panels are easily interlocked without any additional fixings to create a base suitable for use under any garden building.
A 5ft x 4ft plastic base made from recycled plastic covering approximately 5ft x 4ft (20ft²),
A 2m x 1.35m membrane which is laid under the base to prevent weeds and plants from growing up through the foundation whilst allowing rain to drain away naturally,
5 U-pins used to secure the membrane into the ground.
Our eco-friendly bases are manufactured here in the UK from 100% recycled plastic. Owing to their unique formulation, our strong but flexible blend of recycled plastic makes every foundation both UV and weather resistant. Its resilience against the sun, rain and heat means that your garden base will not rot away or break down over time which can be the case with more traditional foundations such as wood or concrete. With a specially designed cell structure our bases have a large load-bearing capacity (up to 420 tonnes) as well as being fully permeable which means that rain and other liquids will drain naturally away from your garden building, reducing the chances of surface water being absorbed and potentially rotting your shed.
On top of the previously mentioned benefits, our base panels are incredibly simple to install thanks to their lightweight frame and slot & peg connection system that allows a full foundation to be laid in no time at all. You also have a choice on how to finish your plastic base installation, you can either just leave the panels unfilled, fill the base with decorative gravel for a french drain system or use soil and seed to create a grass effect!

What sub-base do I need under my garden base?
We recommend you prepare the ground below your base with approximately 100mm of a compact hard base (type 1 or type 3), a weed-suppressing membrane and sand to level.
What is the difference between compact hard base type 1 or type 3?
Compact hard base, type 1 is much finer and can occasionally dust while the compact hard base, type 3 is larger and more permeable.
Can I put the base straight onto grass or soil?
We recommend not installing directly onto grass or soil but instead, install onto a compact hard base as it creates a sturdy, even base. Soil or grass can and most likely will absorb water leading to sinking and creating an uneven sub-base for your garden base.
Can your garden bases be installed on to concrete slabs/pads?
Yes, they can be installed onto concrete slabs or pads as long as the existing ground is strong and level. The base will allow airflow under the structure and elevate it away from any potential surface water.
Should I use a damp membrane between my base and my garden structure?
No, we do not recommend this as although it will keep damp from rising to your structure, any dampness that leaves your structure will then sit on top of the membrane directly under.
How much gravel or aggregate should I use to fill my base?
Approximately 8kg of gravel or aggregate is required to fill each panel, or 72kg per m².
What size gravel should I use?
We recommend using anything up to 20mm in size.
Does the garden base need to be filled with gravel?
Our garden bases are more than strong enough without a gravel fill, able to withstand up to 420 tonnes per sqm. The gravel can be used to compact and enforce even more whilst also being a decorative finish.
Does this product come with pins or membrane?
Yes, our garden base kits come with pins and a sheet of membrane.
Can garden base panels be cut to size?
Yes they can be cut and we recommend doing so with a fine tooth saw.
Do I need pegs or anchors to secure my base?
Pegs and anchors to secure you base are only necessary when installing on areas which have a gradient over 12%.
How do I know which side of the panel to put down?
The bottom of the base has ‘X-Grid’ written on it, indicating the face you put on the ground.
Can the base panels be stacked on top of each other?
No, they are not designed to be stacked.
Where can I find installation instructions?
Install guides can be found on the ‘downloads’ tab. In addition, more information on installations can be found through our blogs and YouTube videos.
Can I create a grass base with the use of your garden base?
Yes, grass can grow in the panels cells when correctly filled with soil and seed.
Do your plastic garden bases have a warranty?
Yes, our bases have a 10 year manufacturer warranty.
Can I be guaranteed the same colour all throughout my product?
Our products are new generation, manufactured entirely from post-consumer recycled plastic; this means you may occasionally find very slightly different shades of colour.
