trees and structures

[Stephen Blair]

how close can a tree be beside a building? i have taken lots of trees away beside houses because it is better safe than sorry, but is this really the case. i read a really good article that que gardens had wrote, and it had a recomendation for species and size.but i lost it:thumbdown:thanks in advance. stevie:001_smile:

Take a look at this its give you a break down on foundation depth in relation to distance from a tree and different species.

Until it touches, because then it wouldnt be close, it would be actually touching.

Go to Oz. Observe trees living in harmony with buildings.

 

Then try and talk to an insurance company over here.

 

AAAAARRRRRRRGGGGGHHHHHHHH!

in nz there were trees growing through houses, it was amazing, and they were a good size too:001_smile:they had built the new houses around them

How do they get past BS5837 with that one:001_tongue:

There's no straight answer. It will depend on the species / size of tree, the type of stucture, and the ground conditions.

 

Species / size of tree: Damage can be caused directly by the tree - eg by limbs falling onto the structure, increase in girth of stem, branches or roots that are touching the structure. The likelehood of this kind of damage will be influenced by the species / size of the tree.

 

Type of Structure: Old buildings that don't have footings, or that are flexible stuctures, such as timber frame may not be compromised by soil movement. Modern buildings with piled, raft or suitable strip foundations may also not be affected. On the other hand, rigid structures with inadequate concrete foundations can be cracked if the ground moves.

 

Ground conditions: Clay soils expand when they are wet and they shrink / crack when they dry out. Trees can increase the shrinkage effect by removing additional water. Modern buildings with strip foundations, normally have their foundations designed to avoid the additional shrinkage caused by existing trees. Problems can occur if new trees are planted within an influencing distance of the building and the foundations haven't been designed to accommodate them.
