Sharp sand in mortar makes a harsh, difficult mix that will not spread or hold on the trowel; building sand in concrete or beneath paving produces a weak slab and a bed that settles under load. The simple rule is soft sand for mortar and pointing, sharp sand for concrete, screeds, and paving beds. The 25kg bag suits smaller jobs, repairs, and DIY projects where a bulk bag would be more than is needed, and keeps the sand clean and dry until use.\u003c\/p\u003e","brand":"Home \u0026 Trade","offers":[{"title":"Default Title","offer_id":55403665719623,"sku":"TRADE005","price":3.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/7759\/6999\/files\/TRADE005.jpg?v=1791879100"},{"product_id":"mot-type-1-scalpings-bulk-bag","title":"MOT Type 1\/Scalpings Bulk Bag","description":"\u003ch5\u003eProduct Descriptions:\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003eOur MOT Type 1 is a graded crushed limestone sub-base supplied in a bulk bag, used to form the compacted foundation beneath paving, driveways, and hard surfaces.

It is used for laying block paving, setts, and natural stone, bedding slabs and edgings, filling joints between setts and cobbles, topping and binding pathways, and as a fine blinding layer over a coarser sub-base.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eGranite dust compacts to a hard, stable surface in a way that sand cannot. The crushed particles are angular and vary in size, so under a vibrating plate they lock tightly together with very few voids, forming a firm, level bed that holds paving in position and resists the rutting and settlement that occur when blocks are laid on a loose or poorly graded material. That stability is why it is preferred for driveways and trafficked areas, where sand alone will migrate under load over time.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSupplied in a bulk bag containing approximately 850kg, it is ready to spread, screed, and compact. For paving, lay over a compacted sub-base to the required depth, screed level, and compact before laying the units. It also works well brushed into the joints of setts and cobbles, where it binds as it takes up moisture and settles firmer than kiln dried sand. Coverage will vary with the depth laid, so calculate to the bedding depth specified for the job.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eBulk bags contain approximately 850kg.

Supplied in a Maxi Bag, it is used to finish new block paved driveways, patios, paths, and parking areas, and to top up joints on existing paving where the original sand has washed out or been lost to pressure washing.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe kiln drying process is what makes this sand suitable for the job. Removing all moisture leaves the grains loose and free-flowing, so they run fully into the narrow gaps between blocks rather than bridging and clogging at the surface as damp sand does. Once the joints are packed, the sand locks each block against its neighbours, preventing sideways movement and distributing load across the whole paved area. Without it, blocks shift, rock, and gradually work loose under foot and vehicle traffic.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTo apply, make sure the paving is completely dry, then spread the sand across the surface and brush it into the joints in several directions until they are full. Run a vibrating plate over the paving with a protective mat fitted to settle the sand down into the joints, then brush in more sand and repeat until the joints stay full. Sweep off any excess from the surface. Well-filled joints also help resist weed growth and ant activity. One bag covers approximately 5m² of standard block paving.\u003c\/p\u003e","brand":"Home \u0026 Trade","offers":[{"title":"Default Title","offer_id":55403702321479,"sku":"WHITE003","price":5.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/7759\/6999\/files\/BuildItKilnDriedSandMaxiBag.jpg?v=1791879256"}],"url":"https:\/\/homeandtrade.co.uk\/collections\/aggregate-sub-bases.oembed","provider":"Home \u0026 Trade","version":"1.0","type":"link"}
