About Our Garden Base Kits

With each kit you will receive the following:

  • 8 garden base panels manufactured from recycled plastic covering approximately 2ft x 4ft (8ft²),
  • A 2m x 1.35m membrane which is laid under the base to prevent weeds from growing up and through the foundation whilst still allowing rain and nutrients to reach the ground below,
  • 5 U-pins used to secure the membrane into the ground.

You can use the 2ft x 4ft kit alone or combine multiple kits to create larger base sizes.

Our eco-friendly garden foundations are manufactured in the UK from 100% recycled plastic. Owing to their unique formulation, the flexible but incredibly strong blend of recycled plastic makes every foundation both weather and UV resistant. Its resilience against the sun, rain and heat means that your plastic shed base will not break down or rot away over time which may be the case with more traditional foundations such as concrete or wood. With a specially designed cell structure too, 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 structure, reducing the likelihood of surface water being absorbed and potentially rotting your shed or hot tub.

As well as the previously mentioned benefits, our hot tub base panels are incredibly simple to install due to their lightweight frame and slot and peg connection system which allows a full foundation to be laid in no time at all. You also have a choice on how to finish your garden base installation, you can fill the panels with decorative gravel for a french drain system finish, fill with soil and seed to create a grass effect or simply leave unfilled!

Will My Garden Building Or Hot Tub Be Compatible With Your Base Kit?

Simply, yes. Our bases can be used as a solid foundation for almost any garden building or hot tub regardless of their size, shape or purpose. They will support sheds, hot tubs, log cabins, greenhouses, summerhouses and so much more – as long as the base is the correct size!

Our versatile base kit is suitable for use under:

  • Sheds
  • Hot Tubs
  • Swim Spas
  • Greenhouses
  • Log Cabins
  • Summerhouses
  • Playhouses

For information on how to correctly install your base, take a look at our Installation Guide which will help you through the process of laying your own garden building foundation. If you cannot find the correct sized plastic base for your garden structure or have any questions regarding our base or other products then please do not hesitate to contact us, you can call us, live chat to a member of our staff now or leave us a message.

What are your Garden Bases suitable foundations for?

Our plastic garden bases are incredibly versatile and can be a suitable base for almost all sheds, greenhouses, log cabins, summerhouses, wendy houses, hot tubs, swim spas and more. Please contact us if you are unsure of compatibility.

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.

How much is delivery?

The cost for delivery can be seen when you add your product to basket and at checkout.
