Haddonstone (semi-dry cast limestone)

This is a unique form of cast limestone, with a surface texture, feel and strength similar to Portland or natural limestone. The principal materials for this are limestone, white cement and sand, a mix which has a feel of damp sand or earth. This stone is packed into the mould either by hand or a pneumatic hand rammer. No finishing is required with this material due to the quality of the mould manufacture and casting, resulting in a look that’s virtually indistinguishable from natural quarried stone and weathers beautifully.

While displaying similar properties to that of natural stone, cast stone is significantly more cost effective piece for piece, making it the ideal choice for many ornamental and architectural products. Our vapour curing process gives the stone the equivalent of 14 days’ strength overnight, which results in reduced delivery lead times and improved handling.

TecStone (wet-cast limestone)

We also manufacture products using a wet-cast production process – this material is called TecStone. Denser than our standard Haddonstone, it’s made of much larger particle sizes and exhibits a higher water content, which means it doesn’t need vapour curing. Hand finishing is necessary at the end to ensure a high quality product. The TecStone mix is poured into a mould. This process gives a finish, once acid etched, much more akin to Coade stone. It has a smooth and sealed surface, which makes it ideal for flooring, fireplaces, complex statuary, larger architectural products and contemporary designs where clients prefer a surface finish that does not weather quickly. It’s also usually easier to clean for this reason.

We use TecStone for a number of our products, particularly those used in larger architectural projects, such as columns and paving. TecStone is designed to meet demanding performance criteria and as it can incorporate structural reinforcement, it tends to be the preferred material for architectural projects requiring structural strength as well as cast-in fixings.

TecLite (fibre-reinforced)

This revolutionary cement-based material contains alkali-resistant glass fibre (Glass Fibre Reinforced Concrete). Although it closely resembles cast stone in appearance, the use of thin wall construction teamed with GRC/GFRC technology means the component weight is reduced by approximately two thirds when compared with similar Haddonstone and TecStone pieces. Its high strength to weight ratio makes it ideal for new build, retro-fit, timber frame and new build projects. It can also be used to achieve the same crisp detailing normally only achieved with Haddonstone designs. Robust and lightweight, TecLite can be used in conjunction with Haddonstone architectural components.

Haddonstone for building

Our TecStone material can be reinforced with structural steelwork to make it suitable for structural projects. We’re able to work in conjunction with architects and structural engineers to manufacture TecStone components to fulfil clients’ requirements for specified application.

Bespoke stonework capabilities

We’re able to manufacture architectural stone pieces to bespoke shape and size requirements. We’ll replicate simple or intricate designs to individual specifications in any quantity. Both our UK and USA manufactories have in-house studios that specialise in creating moulds for this purpose. We’re dedicated to ongoing investment in research and development in this area, to ensure we’re always at the forefront of solution development for our clients.
