About the ProBASE 11x11 Plastic Shed Base Kit

The ProBASE 11x11 Plastic Shed Base Kit is a ground base made of interlocking plastic grids. Looking for a square footprint? The 11x11 kit gives you equal sides. It is a quick alternative to laying slabs or concrete under a new shed.

The 64 squares build an 8 by 8 grid. That is 4m by 4m with the same width and depth. Each square measures 500 x 500 x 40mm. The pack holds 64 squares and a heavy-duty commercial-grade weed membrane. The grids are made from 100% recycled plastic.

Lay it on a firm level area. Interlock the squares then add pea gravel. The advice is 15kg per square (gravel not included). The design lets air and water move under the shed. That helps keep the floor dry. The square layout suits corner plots and square summerhouse-style sheds.

It is lightweight yet strong. You can lift it and reuse it if you move the shed. It carries a 2 year guarantee. It suits square sheds and corner plots.

What It Is Made From

The squares are made from 100% recycled plastic. The material will not rot like timber. The grids are lightweight but strong enough to carry a shed.

Which Sheds It Suits

Made for sheds with a 11' x 11' footprint. It suits square sheds and corner plots.

Good to Know

The base is a set of 64 square grids that clip together. Each grid is 40mm deep. Filled with gravel they spread the load of the shed over the whole area. Open cells let rain drain and air move underneath. That cuts damp and rot risk for the shed floor. The membrane below stops weeds pushing up through the cells.

Laying the Base

Clear and level the ground before laying. Wear gloves when handling grids and gravel. Gravel is heavy so use a barrow and bend your knees. Check the base is flat before building. Follow the supplied instructions.
