This cradle system is not only designed to increase the build height of the floor but also to deal an un level subfloor, a great option as opposed to screeding an entire sports venue. There are 4/5 cradles per sports batten length and are laser levelled every row that goes down.
70-140mm build height
un level sub floor control
Area elastic qualities
This low build option is designed for arenas where a sprung build height cannot be accomidated. The boards are given sufficient backing with sports grade underlay and adhered to each other with flexible adhesive to allow flex movement and expansion. This system is not area elastic but point elastic.
Low build height allowance
30mm build height
This system is very similair to the last however has a double bat instead of a single counter batten. This gives the system extra height. The counter batten can be swapped out for T&G plywood, this would be advisable for when a venue has bleachers or seating. Takes a long time to install.

Extra durability if T&G ply subfloor is installed
good sports performance
