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.

What are your garden bases suitable for?

Our plastic shed bases can hold up to 420 tonnes per square meter. They are a suitable foundation for almost all greenhouses, log cabins, summerhouses, wendy houses and even sheds with heavy equipment inside. Please contact us on live chat if you are unsure.

Can Shed Bases be installed on to concrete slabs/pads?

Yes, they can be installed onto concrete slabs or pads. The base allows airflow under the shed and elevates it out of any potential surface water.

Should I use a damp proof membrane between by 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 aggregate/gravel should I use?

8kg of aggregate/gravel per panel or 72kg per m2

What size gravel/shingle/pea shingle should I use?

We recommend using anything up to 20mm.

Does the shed base need to be filled with gravel or is it strong enough without it?

The shed base is strong enough without gravel. The gravel can be used to compact and enforce even more and for decorative use.

Does this product come with pins or membrane?

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

Which membrane should I use?

We recommend using a woven membrane with a plastic shed base

Can I cut the shed base panels?

Yes they can be cut and we recommend using a fine tooth saw.

Do I need pegs to secure my base?

Only areas which have a gradient over 12% will require pegs.

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, the bases were not designed for to be stacked when installed.

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.

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.

Will the shed base allow grass to grow in its cells?

Yes, grass can grow in the panels cells when 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 or similar 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.

How much is delivery?

Delivery is £10 for any quantity of grids, bases, mats, tiles and accessories.

How quick is shipping?

We typically endeavour your product to be delivered within 3-5 working days but the expected delivery time of your purchase will be displayed clearly at checkout.
