Check what size your tree is going to grow! Look at this illustration, in all cases the products used were unsuitable for the application. The sad thing is that these situations have not happened overnight, and in all cases something should have been done sooner.

The whole point of tree protection is to aid soil stabilisation, stop soil compaction, ensure the easy passage of nutrients to the root system, aid drainage, and to protect the tree during its early development. Careful specification can avoid the this happening.

Care must be taken if comparing prices from differing manufacturers. There are no British Standards to cover this sector, (or many others), therefore products can often be made to varying standards. We at CIS Street Furniture are trying to implement our own standards, a leaf has been taken from the British Standard for Manholes, and consequently all CIS grilles when combined with medium duty frame will withstand a 6.5 tonne slow moving wheel load, (for occasional traffic areas).
