Usage
Primarily used for decorative horticultural landscaping, 40mm slate's flat, interlocking surface makes it ideal for footpaths and walkways, offering a smoother, more navigable surface than rounded gravel. It is also commonly used for garden bed edging, mulching (with ground membrane to boost moisture retention and suppress weeds), building rockeries, and defining paved patios.

MOT Type 1 has crushed gravel stones that form the granular sublayer for road surfaces and pathways. Hardwearing, this gravel provides a load bearing stable layer and a flat surface prior to laying paving or hard standing areas. The fine mixture also ensures minimal voids in the sublayer when compacted.
