Find out everything about our extensive DELTA®- Foundation protection range, from damp-proof and sub-base courses to dimpled sheets.

Beyond that, DELTA® offers numerous drainage sheets which will safely drain off water and protect buildings reliably from moisture even when installed comparatively deep below ground. Dimpled sheets specially developed for extremely severe requirements have been installed in, for example, the building project of the century – the Gotthard tunnel.
