Need a flat start for a wide building? The ProBASE 18x11 Plastic Shed Base Kit covers 18' x 11', or 6 x 3.5m. Inside the pack are 84 grids and a roll of weed membrane. It replaces a slab or concrete job.
The grids measure 500 x 500 x 40mm. Interlocking edges link them into a single mat. Once laid, the base lets air and water flow under the shed. That helps keep the floor dry. For best results the makers suggest 15kg of pea gravel per square. You buy the gravel separately.
Pick a firm, level site and lay the membrane first. Then click the grids together. It is simple to lay and assemble. The finished base is light yet strong. If you shift the shed one day you can lift and reuse the whole kit.
It suits owners of wide sheds and outbuildings. Recycled plastic makes it kinder to the planet than poured concrete. Heavy-duty membrane and a 2 year guarantee round out the kit. Instructions and customer service support come with it.
