As a construction aggregate, Welsh slate can be used as a granular sub-base for footpaths and driveways due to its excellent load-bearing qualities. It can also be used as pipe bedding, washed sand for use in concrete and slate sand as a base for laying block paving.
Welsh slate can also be used as decorative chipping as it does not oxidise and keeps its natural colour indefinitely. Its natural flat shape also provides good coverage per tonne and thus value for money.
Billed as an attractive practical mulch for gardeners and landscapers, it is suitable for domestic and commercial applications including garden footpaths, flower/shrub beds, weed suppression, pond lining, municipal car parks and footpaths, caravan parks, golf courses, and cycle and forest tracks.
And when blended with sterilised PAS100 compost Welsh slate aggregate makes a high-quality topsoil suitable for all landscaping requirements including grass sowing, trees, shrubs, turfing, herbaceous borders and other plantings. It can be used on brownfield land to help improve previously contaminated sites.
Available in blue, plum, grey and green and two grades (50-30mm and 30-10mm), Welsh Slate aggregate samples are available on request, complete with full gradation certificates and Health and Safety data sheets.
