Demolition and recycling - Options for recycled brick material

Tennis court sand

Sand for surfacing tennis courts is produced by crushing red bricks and roof tiles.

The material is produced by crushing in hammer mills to a grain size of 0-2 or 0-4 minimum. The process is most efficient when it occurs at brick or tile factories where there is an abundance of scrap material. Different bricks will give different qualities and colours of tennis sand. Clinker quality will have numerous benefits:

• Better water drainage
• Unique colour
• Greater density (less wind scatter)
• No moss problems

Dust may arise during production but the problem can be minimised by enclosing the crushing equipment and if necessary, using water sprayers.

The requirements for sand and other materials used in tennis courts may be laid down in standards and specifications stipulated by tennis governing bodies. The main requirements are water permeability, grain size distribution, surface shear stability and a satisfactory proctor test. The fine surface layer is laid over courser-grained layers that can comprise crushed clay brick matter.
