The product can be installed by using two methods of fixing a) surface mounted by bolting down with rubber expanding bolts or b) laying a concrete raft and fixing with anker bolts.
Asphalt surface mounting:
This method should only be used if the asphalt surface is older than 6 months and has a crust of asphalt depth of 50mm or greater. The benefits of using rubber bolts are that they offer a “dampening” effect when traffic passes over. Rubber fixing plugs have an out side diameter of 22mm and are 75mm in depth, the actual bolt size is an M12 x 100mm.
The product should be laid in desired location, drill hole area should then be marked out. All holes should be drilled prior installation, do not fit the product until all of the surface holes have been drilled out.
Important note: The rubber plugs and fixing bolt should be fitted to the product prior being dropped into location. Once the bolts have been loosely fitted drop the entire unit into the pre-drilled holes, you will save hours of time!
Fitting a concrete raft:
This method should be used if the road surface is in poor condition, is newer than six months old or has a asphalt surface depth of less than 50mm.
A concrete foundation/slab should be laid, reinforcing should not be used. Once the concrete has set the product should be fitted as per the diagram below.
