This plastic shed base kit is suitable for sheds that measure 7x5, creating a stable base for your shed to sit on. The plastic shed base kit is manufactured from 100% recycled plastic which means makes you much more environmentally friendly. Instead of using concrete to create the base or using a timber base that can rot, this plastic shed base kit is a brilliant choice. The simple interlocking design means fitting the base is extremely easy and can be placed on any flat ground surface. When placed we recommend that you add pea gravel to prevent water clogging and aid water distribution. This handy base also allows for ventilation underneath your shed keeping it dry. Each square grid is 500 x 500 x 50mm. This pack contains 15 squares. Please note gravel not included with shed base we recommend using 15kg of 10mm pea gravel per square. Our pro bases are only available for delivery to mainland uk.
