Avoid the hassle or mess of laying slabs or concrete with our 14'x14' ProBASE plastic log cabin base kit, when preparing a base for your new garden building. It is very quick to install as its interlocking design makes it easy to put together and, though lightweight, it will provide a very strong and durable base for your log cabin. Made from 100% recycled plastic, this log cabin base is eco-friendly. Also, you can reuse the base if you decide to reposition your garden building. The base allows for ventilation and drainage under the building, helping to keep the shed floor dry. To install the base, you simply interlock the square grids together and lay onto a firm, level area of ground. We recommend using 15kg of 10m pea gravel per square (gravel not included). Each square is 500 x 500 x 40mm. This pack contains 81 squares and heavy-duty, commercially-graded weed membrane.
