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.
