Timber Preservation

Pressure impregnation is the only reliable method of increasing the durability and service life of softwood timber.

At Calders and Grandidge we carry out all our third party treatment services to the same exacting standards we use for our products, and offer treatment for User Class 3 (no ground contact), User Class 4 (in ground contact), and Highways (Sector Scheme 4).
