Trevor May has completed work on converting 10 old tennis courts at Eton College in the UK to the Smashcourt surface.

A porous macadam surface, the courts were built on a porous stone foundation to provide a stable, free draining base.

Designed to play like a natural clay court with slow and high bounce, the surface enables play all year round and is fast-draining to allow play immediately following rainfall.

The Smashcourt surface requires no irrigation, meaning there is less capital outlay to begin with and water bills are made redundant.

Maintenance is intended to be simple through the use of drag brushes - designed to keep the surface flat and true - which come as part of the Smashcourt package.

The work was the second stage of a contract the company had with the college, which consisted of the conversion of five courts into an impervious acrylic surface.

Since the work has been carried out, the number of pupils playing tennis at Eton is said to have increased significantly.
