Civil Engineering Developments (CED) Limited was formed in 1959 to devise applications for calcined flint within resin technology, but it was soon clear that the venture was unfortunately beyond the resources of the family. It was in 1978 that Michael Heap recognised that the company had the basis to become a supplier of specialist aggregate and stone.

The family's involvement with stone, specifically flint, dates back to the middle of the 19th century, supplying raw flint from France to the ceramic industry by ship and canal boat. When similar flint became available in Essex as a by-product from chalk extractions for cement manufacture, Michael's grandfather A.L Walley installed a small processing unit at West Thurrock in 1931. When his death soon after was followed almost immediately by both sons, Nora Walley, then a 23-year-old budding tennis player, bravely took over the management. Flint supplies from France were cut off by the war and West Thurrock production became vital to the ceramic industry. Many other applications for calcined (cooked) flint were developed in the 1050s and 1960s and the business prospered but after the closure in the late 1970s of the last local cement works, the calcined flint production business was sold.


From very small beginnings, CED has grown by fulfilling market needs within the field of natural materials ranging from technical uses for fine dried aggregates to beautiful pebbles and huge boulders. By making the relatively unusual readily available, CED has enabled landscape architects to effect exciting designs for lakes, rivers and specialist water features. In the field of paving, first by buying and holding in stock large quantities of reclaimed granite setts, kerbs and York flags, these materials became practical for specifiers to consider, and secondly, by actively marketing a whole variety of new stone. CED has prompted, encouraged and led the moves to improve the hard surfacing of public and private areas alike.

Now with five depots spread nationwide, together with a broad exciting range of products, CED has the foundation prepared to deal with the growth in demand which it has itself done so much to foster and which is so welcome in the improvements being made to urban paving. At last it is again recognised that stone is not only aesthetically pleasing but it is often cheaper when compared on whole-life costing
