The ProBASE 11x9 Plastic Shed Base Kit is a ground base made of interlocking plastic grids. Got a small shed to site? This one suits 11x9 buildings. It is a quick alternative to laying slabs or concrete under a new shed.
The 42 squares build a footprint of 3.5m by 3m. That fits the common 11x9 sheds and anything a bit smaller. Each square measures 500 x 500 x 40mm. The pack holds 42 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. It is the smallest kit in this set. Fewer squares means less gravel to buy and a shorter job.
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 small to mid-size garden sheds.
