Alternative Treatment for Historic Buildings


Historic buildings are part of our built environment. Many are important icons of our past and form part of our heritage and culture. They also provide excellent opportunities for reuse and development and can serve as the focal point for the regeneration of many rundown, post industrial areas.

A holistic approach to the investigation of historic timber using non-destructive techniques to inspect and examine timber in situ for strength reducing defects, combined with repairs undertaken with the minimum of interventions, where practicable, can facilitate the re-use of original structural timber and can contribute to the 'recycling' of historic buildings.

The remedial treatment of timber decay in British buildings is a comparatively recent activity. Previously, if any action was deemed necessary, infected or infested timber was cut out and replaced. Construction professionals, contractors and specialists from the wood preservation industry employed basic and often damaging methods to the assessment and treatment of fungal and insect infestations in historic buildings.

For example, the slightest suspicion of dry rot often resulted in masonry walls being peppered with bore holes for injecting fungicides, while plasterwork and other decorative features were damaged during invasive survey works.

Our role in the preservation and renovation of historic buildings is in the blending of a lightweight filler formulation which is used for reinforcing traditional timber frame buildings.  Our lightweight microspheres are integral to the mix to enable the filler to adhere to the existing timber without slumping. This is a particularly important contribution for ceiling joist and wall studs where the filler may not be supported.

Consistent with all our bespoke blending services, we engage with our lightweight filler customers to assure that the blending methodology and product packaging are consistent with their requirement and expectation.
