Quick and simple to install, the 5.5 x4m Log Cabin Base Kit is ideal for avoiding the hassle of laying slabs or concrete when preparing a base for a new log cabin. Its interlocking design makes it easy to put together and, though lightweight, it provides a very strong and durable base for the log cabin. Made from 100% recycled plastic, this log cabin base is eco-friendly. Also, it can be reused if the cabin is repositioned. The base allows for ventilation and drainage under the log cabin, helping to keep the floor dry. To install the base, 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 88 squares and heavy-duty, commercially-graded weed membrane.
