Polymeric Surfaces
Courts consist of a Permeable Foundation of crushed, graded stone, topped with Porous Macadam. The polyurethane surface is then applied directly to the macadam, or to a polyurethane and rubber cushion layer.

Polymeric surfaces are formed from a complex mix of polyurethane binders and rubber granules with a top coating. The materials are either mixed on site and laid as a wet pour material, normally through a small paving machine, (although hand laying is sometimes used) onto a macadam base or supplied in factory produced rolls that are bonded to a macadam base.

Colour Coating & Sports Lining
When installed a s a wet pour system the resulting rubber mat may be colour coated to improve appearance and additional texture added to provide the high degree of slip resistance required by sports such as tennis and netball. Play lines are normally applied using a compatible polyurethane paint.

At present only Solvent based Polyurethane Paints possesses the inherent strength and necessary flexibility required to adhere correctly to a Polymeric Surface.

Maintenance Requirements
Polymeric courts also have periodic maintenance requirements. A newly laid surface should give firm foothold and good medium-paced ball speed.

As the surface is used over the years, however, it will become smoother and more polished and this may result in increased ball speed and some impairment of grip when the surface is damp.

When this happens it is time for the surface to be re-painted. Normally this may need to be carried out every four years. It can only usually be carried out on three occasions before the surface water infiltration rates are reduced below an acceptable standard.
