                  Haddonstone also manufactures products by a wet-cast process, called
                  TecStone.  Here, the mix is poured into the mould. This process gives   While experts have, more than once, confused Haddonstone with

                  and contemporary designs where clients prefer a surface finish which
                  does not weather quickly.  TecStone is a high specification stone
                  incorporating reinforcement if required in structural situations as well as
                  cast in fixings.  Designed to meet demanding design and performance
                  criteria for commercial projects and large or small scale individual private
                  developments.  Hand finishing is required to ensure a quality product.

                  TecLite (fibre-reinforced)
                  Although TecLite closely resembles traditional cast stone and natural
                  stone in appearance, the use of thin wall construction and GRC/GFRC
                  technology means component weight is reduced by approximately two
                  thirds when compared with similar Haddonstone and TecStone pieces.

                  TecLite is a cement based material containing alkali-resistant glass
                  fibre which benefits from a high strength to weight ratio. Architectural
                  products made by the TecLite process are ideal for retro-fit, timber-
                  frame and new build projects.

                  TecLite products are robust and lightweight and can be used in
                  conjunction with Haddonstone architectural components.  TecLite
                  products can be used to achieve the same crisp detailing normally only
                  associated with Haddonstone designs.
