SuperCEDEC® is a durable, free-draining footpath gravel that was first developed in 1991 as the CEDEC® range. Originally designed to pack tightly rather than set, CED has now developed SuperCEDEC® for situations where this is not desirable, such as high usage areas and places where it adjoins hard paving. SuperCEDEC® has the same natural appearance as CEDEC® but only a slight loose crumb on the surface. It is much firmer than CEDEC®, but equally permeable.

Applications

Although both CEDEC® and SuperCEDEC® are footpath gravels designed for pedestrian application, occasional use by emergency vehicles, cars, lorries or maintenance equipment will not cause any significant damage, providing the laying instructions have been adhered to.

The permeable nature of SuperCEDEC® combined with its more stable structure make SuperCEDEC® ideally suited for use in urban tree-pits and footpaths.

Materials

CEDEC® and SuperCEDEC® footpath gravels are comprised of granite and quartzite, which are chemically inert and durable and will not affect the pH value of the surrounding soil. This is important where newly planted trees or pH-sensitive plants are sited. As SuperCEDEC® has the base ingredients of CEDEC®, it retains the porosity of CEDEC® but the additives make it much firmer.

Like CEDEC®, in order to function effectively SuperCEDEC® needs to be used and rained upon. However, it will also function under cover if watered.

Coverage

After compaction, coverage of SuperCEDEC®, either in tree pits or as a footpath gravel, is approximately 10m2 per tonne at 50mm thick, compaction being about 25%. So, in order to compact to 50mm, an initial non-compacted layer of 65mm is required.
