What is Kiln Dried Sand?

You may refer to kiln dried sand by a variety of different names. While it is commonly called paving sand, various companies will use different names including silica sand, silver sand, jointing sand and dry aggregate sand. In any case, they are all one of the same. These sands come in various colours although you wouldn’t typically have a choice in this and would normally go with what your supplier has in stock. But it isn’t the aesthetic of the sand that makes it so effective for block paving, but rather the texture. Kiln dried sand contains no moisture at all and is dried in a kiln to ensure that none remains. This, along with its very fine texture makes it ideal for packing between paving slabs and block paving blocks to keep the structure stable and strong. Moreover, being dry means that it will more easily penetrate down between the blocks rather than clumping together as wet sand would. When present, your driveway is far less likely to move.
