Over 3,500 tennis courts renovated since January 2000
Resurfacing a tarmacadam tennis court with new tarmac is a major expense and if a court is probably maintained the tarmacadm surface should last 15-20 years.
Unfortunately we have seen brand new surfaces wrecked in four years just due to non existent maintenance. What happens is the moss and algae attacks the surface first destroying the acrylic paint and then attacking the actual tarmac. This destroys the binder which holds the tarmac together and it starts to break up (Fretting). Once this happens it will not belong before a new tarmac surface is required.
Before a court surface can be re laid the surface has to be pressure cleaned to remove all the moss / algae and dead matter which has fallen into the surface. If this is not completed it will seriously effect the drainage on the new surface. It will quickly become blocked as there is poor drainage underneath it.
The surface also has to be “Spiked” with 1” holes drilled at one metre intervals to open the old surface and allow the drainage to be complete. These holes are then filled to ensure an even surface. Only then can the new tarmacadam be laid.
Spiking the Surface
The surface also has to be “Spiked” with 1” holes drilled at one metre intervals to open the old surface and allow the drainage to be complete. These holes are then filled with “pea” gravel to ensure an even surface. Only then can the new tarmacadam be laid.
Resurfacing with new tarmac
This is an extremely skilled operation and is completely undertaken by hand laying and then power rollering to provide an exceptionally flat even surface.
Failure to have an even surface will result in hollows “Bird Bath,s” which just collect moss and algae and can ruin the tarmacadm surface.
