Help for building firms

NHBC, the leading warranty provider and standards setter for UK house-building, has announced the launch of their first-ever app to aid builders calculate the correct foundation depths when building near trees.

It is hoped that the app, which will be available free of charge to all NHBC registered builders, will assist in bringing down foundation-related claims, which over the past four years have cost the industry more than £36m, approximately £9m each year.

The foundation depth calculator provides builders with an effective field-based tool to assess tree types and required NHBC Standards 4.2 foundation depths via their mobile phone or handheld device. The majority of trees in the UK have a significant radial root system, extending one to one-and-a-half times the height of the tree, meaning that the correct foundation depth is crucial.

The app is available free of charge on IOS and Windows OS to all NHBC registered builders. Please visit for further information.
