Kiln Dried Sand 25kg Bags For a reliable supply of quality kiln-dried sand in Basildon, Chelmsford and Southend, our experts can help. Kiln-dried sand is a fine, moisture-free sand which is ideal for filling the gaps between paving slabs – making them strong, sturdy and water-tight.

The sand is created by being dried out in a kiln, and must also be applied in dry conditions to be totally effective.
