Natural Stone Repairs
Historic buildings made from natural stone contain varying materials with different static functions. Damp and saline-laden supporting walls, cracks, spallings and cavities are where the most damage occurs.

We match product systems and injection methods to ensure that your repair lasts for years to come.

Unreinforced Masonry Repairs
Brickwork can be injected to fill cavities and stabilise the substrate. All brickwork has its own requirements and must be treated accordingly, with the right systems. Matching injection materials to the brickwork and building substance ensures the integration of different chemical and physical properties.

A flexible, lightweight FRP system may also be used to confine existing substrates
