LONG JUMP RUNWAY - Key Persons
Nearly every site in Chalfont St Peter will follow the same long jump runway construction process; step one in installing a long-jump is to ensure the area has been prepared.
Typically a geotextile layer will be fitted to prevent weeds from growing beneath, through or on the surface of the run-up track, then the sub-base layer is laid on top.
A polymeric surface sub-base is made with a layer of stones and macadam which creates a sturdy foundation.
