NHBC  Foundation Depth Calculator

 

NHBC used to provide a Foundation Depth calculator that allowed users to simply line up a tree height and tree distance, then read off the foundation depth.  It may not be available now?

There is however  a useful free NHBC foundation guide booklet:     nhbc foundation guide – FREE BOOKLET

Or check foundation depths with Local Authority Building Control – LABC’s foundation depth calculator
