| Tree damage to building foundations
Does any one know anything about this subject, or know of any good references?
I have a wonderful copper birch growing on the border between my garden and my neighbours, who have started making rumblings of concern that the tree could be causing foundation damage. The tree is about 20 foot high (reaches 1st floor windows about mid way) and has probably doubled in height since we bought the house 2 years ago - the previous owner used to cut it back each year, but we wanted to let it gain some height to screen our garden a bit, so most of the height is from thin, new growth.
I think that arborologists use a reference document that allows an approximation of root radius based on crown condition, height and species, but I’ve no idea what it is - it might even be a British Standard.
Also, does anyone know how the tree root system will react if I undertake some severe pruning - if I coppice the tree, will the roots die off / stop growing / grow more to compensate?
If the tree roots do extend up to the building foundations, will their growth be powerful enough to cause damage anyway?
Any thoughts appreciated.
