2 Options to Use for Paver Sand DoItYourself

Silica Sand. This was once the most popular type of paver sand, but it had many disadvantages. The sand was generally placed between the pavers after fitting, and this improved the fitting of the pavers, but it had to be kept stable by adding a sealant over the top, and was often washed away during storms.

Beryllium copper Wikipedia

Beryllium copper is a non-ferrous alloy used in springs, spring wire, load cells, and other parts that must retain their shape under repeated stress and strain. It has high electrical conductivity, and is used in low-current contacts for batteries and electrical connectors. Beryllium copper is non-sparking but physically tough and nonmagnetic, fulfilling the requirements of ATEX directive for Zones 0, 1, and 2.
