Proposal 2

Concrete paving slabs laid in a sand-bed:

An effective and economical solution can be achieved by using paving slabs laid in a bed of sand. Paving slabs are available in a variety of colours and finishes from almost every Home worker- and DIY market. Even when the paving slabs are firmly and evenly stamped down in a bed of sand we would still recommend the use of the Biohort Floor Frame (attention: please ensure that a plastic-sheet is placed underneath the sand to protect against rising damp).

Preparation work

		1) The erection site (lawn or earth) is excavated to a depth of roughly 10 cm. (Size of Floor Frame plus desired all round clearance). Where the ground is uneven or the shed is to be erected into a slope or hillside, sufficient compensation must be made to ensure a level foundation.

		2) Plastic sheet should be laid out and the foundation pit filled to within 3 cm of the top edge of the pit with fine gravel. (Depth of the concrete slabs should be at least 4 cm).

		3) The gravel should be evenly distributed throughout the pit. The concrete slabs may now be laid in the gravel and levelled with the aid of a spirit level and a rubber mallet.
