Foundation requirements
General
This net has been designed to allow a rubber safety surface to be used in conjunction
with corner boxes. The surface thickness should be based on the CFH of
850
mm. The
boxes are supplied with a tile glued to the lid, this ensures the finished ground
level is the required 400mm above the concrete.
It is recomended the area is prepared accordingly prior to commencing installation of
the net.
Equipment & Tools
The following equipment is recommended to assist in the accurate installation of the
foundation anchors.
1) Laser Level 2) 20m Measuring Tape 3) JCB Excavator 4) Set Timber
5) Manual Tools: Spade, Sledge Hammer, Claw Hammer & Nails
Time Management
Day One:
1) Set out the Area 2) Accurately Position and Excavate Holes
3) Secure Central, Corner Foundation & Corner Box positions for concreting
Day Two:
1) Concrete Steelwork
Day Three*:
1) Final erection of Activity Net
2) Laying of rubber safety surface material
*The foundation should be left for approximately seven days to achieve maximum
strength prior to assembling the remaining elements.
Foundation Procedure
Setting Out
There are a total of Five holes that need to be excavated. These include one centre
holes (the final position of the central mast) and four holes at each corner (the net
will be attached to the subsequently concreted corner anchors by means of rigging
screws supplied).
All foundation concrete blocks must be at the same level
It is important to maintain 400mm between the finished surface level of the safety
surface and the top surface level of the concrete. Once the correct position of the
holes has been marked prior to excavation, The use of a datum peg (point (b)) is
recommended in order to easily relocate the exact foundation position (both
horizontally and vertically) which was originally established during setting out.
