There are three types of matting in use:-
75mm thick Rubber crumb is recommended for use beneath roped climbing walls. It can be provided in the form of tiles or as a very viscous poured preparation which sets on cooling. It is important to realise that the rubber crumb is not a ‘safety’ mat, but simply minimises the degree of injuries should a fall occur.
Crash mats are 300mm thick made of two densities of foam encapsulated in a hard wearing cover with a separate carpet topping are required below bouldering walls. They are a specialist item which we source from a reliable manufacturer.
When climbing walls are built in sports halls and gymnasiums it is customary to immobilise the lower 2 metres of the climbing wall with 80mm thick foam hanging mats. These protect games players from accidental injury when in position. When the climbing wall is in use they would be unhooked and placed on the floor below the climbing wall as something of a soft landing for climbers.
