A brochure on its aggregates portfolio has been published by Welsh Slate. A guide to the material’s use as an aggregate has been launched by Welsh Slate, the UK’s leading supplier of natural slate for a peerless range of exterior and interior design applications.
The guide gives a snapshot of Welsh slate’s features and benefits as an aggregate, specifically for civil engineering, house building, the water industry, and precast and ready-mixed concrete.
As a construction aggregate, Welsh slate can be used as a granular sub-base for road building, car parks, footpaths and driveways due to its excellent load bearing qualities. It can also be used as pipe bedding, washed sand for use in precast and ready-mixed concrete, slate sand (as a base for laying block paving), capping layers or crusher runs in road building, and as dug/fill, for filling large voids.
Welsh slate is also ideal as decorative chippings as it does not oxidise and keeps its natural colour indefinitely. Its natural flat shape also provides better coverage per tonne, and therefore better value for money, when compared to other aggregates.
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 four colours (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.
