What Is A Plastic Shed Base?

Our individual 330mm x 330mm recycled plastic, interlocking greenhouse base panels can be used to create a full foundation or used as an add on to an existing base to create a base of any size or shape depending on your needs.

What Are The Benefits Of Using A Shed Base?

Manufactured in the UK from 100% recycled polyolefin our plastic bases have been engineered as a lightweight, durable and weatherproof log cabin base system. Environmentally the plastic summerhouse base is one of the best, made in the UK from 100% recycled plastics it is kinder to the environment than other imported competitors and compared to concrete options.

Each panel weighs in at just 0.57kgs each, and because it is light does not mean it is weak. The round cell design without any straight lines means that it is one of the strongest plastic shed base panels on the market. Tested unfilled to 420 tonnes load-bearing capacity per square metre, the playhouse base panel is able to support all types and sizes of sheds, greenhouses, log cabins, summerhouse and more. Our bases are very easy to install too thanks to the specially designed slot and peg system which when paired with its lightweight frame, takes no time at all to lay.

The weather can play a large part in the life of a shed or other garden building so you shouldn’t have to worry about your base not lasting as long as your shed. That is why all of our bases are UV stabilised, resistant to erosion, able to withstand temperatures in excess of 50 degrees C (far hotter than the UK summer), UV stabilised and are fully permeable, meaning any rain or other liquid can drain naturally away from your shed reducing the amount of stagnant surface water that could be absorbed by your shed and lead to rotting.

For assistance in installing your shedbase please read our Install Guide.

What are your Shed Bases suitable foundations for?

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

Can your Shed 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 shed and elevate it away from any potential surface water.

Should I use a damp membrane between my base and my shed?

No, we do not recommend this as although it will keep damp from rising to your shed, any dampness that leaves your shed will then sit on top of the membrane directly under your shed.

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 shed base need to be filled with gravel?

Our shed 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?

No, this particular base comes with neither pins or membrane.

Can shed base panels be cut to size?

Yes they can be cut and we recommend doing so with a fine tooth saw.

If I choose to use a membrane, which should I use?

We recommend using a woven membrane.

Do I need pegs or anchors to secure my base?

Pegs and anchors 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.

What sub-base do I need under my shed 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 create a grass base with the use of your shed base?

Yes, grass can grow in the panels cells when correctly filled with soil and seed.

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 shed base.

Do your plastic shed 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.
