Third party product certification
BES 6001, UKCA, UKNI & CE Marked to BS EN 13164 and conforms with the Construction Products Regulation, BBA 17/5454, Environmental Product Declaration; BBA Certificate 17/5454.
Compressive strength (minimum) at 10% compression
Highly resistant to compression and withstands both occasional and long term static loads. The high compressive strength and rigidity of the product allows a range of ballast material including gravel, soil and concrete slabs to be used as part of the construction.
Load bearing construction elements should be designed to adequately support the combination of imposed and dead loads without creating excessive deflection.
