Paving Sand is very dry fine sand that contains no moisture. The sand is used to fill the joints of block paving and paving slabs. By filling the joints with paving sand you keep the structure of the paving rigid and strong. It also stops the ingress of water & stops the paving from moving and becoming loose.
The sand is dried to remove all the water before it is ready to use. The sand is supplied bagged and dry. It is an extremely fine sand that will flow easily into the joints and gaps in block paving and paving slabs.
Paving Sand is used to lock individual paving blocks together. By doing this you stabilize and strengthen the paving block structure.
The sand in between the joints of block paving prevents water from penetrating the paved area and locks the individual pavers together stopping them from moving. If the joints of block paving are left without paving sand, they may sink due to water penetration and the blocks will become loose over time.
It’s crucial after washing block paving that you replace any lost sand once the paving has dried. This is to prevent water ingress into the paving joints. Unless your paving is designed to be permeable. In which case you should not use kiln dried sand but use clean graded stone chippings.
Crushed concrete is an aggregate composed of clean crushed concrete and brick. The size of this aggregate varies from 75mm down to 40mm.
Sharp sand is typically made from ground rocks and is sometimes referred to as builders sand as its ideal for laying blocks, paving and patios.
Ballast refers to a mixture of sand and gravel that is used to make concrete. Generally, the size of the grains/stones vary from 0.1mm upwards to 20mm.
There are two different types of gravel which are 10mm and 20mm. 10mm gravel, also known as ‘pea gravel’ is primarily used for decorative purposes and drainage.
Topsoil is defined by the top 2-7 inches of soil that has the greatest organic content. Organic matter is what is left after plant roots and leaves.
Building Sand is a finer grade than sharp sand with smaller particles. It’s often mixed with water and cement to make mortar for laying bricks, patio slabs and blocks.
MOT Type 1 is a sub base that is formed using recycled crushed concrete and consists of rubble of varying size. It compacts well to form a solid base which makes it an ideal sub-base.
This sand is used to fill the joints of block paving and paving slabs. By filling the joints with paving sand you keep the structure of the paving rigid and strong.
