Which trees damage foundations UK?
The oak tree is responsible for the largest number of subsidence claims in the UK. The ash tree is another fast growing deciduous tree which prefers moist conditions and whose roots will spread wide distances to find water. Again these are best avoided near houses.
Can a tree be too close to House Foundation?

What are the worst trees for subsidence?
The Solution
Research has shown that the majority of subsidence problems involve trees to some degree. Trees more likely to cause problems than other have fine root structures longer than other species, such as poplars, willows, elms and oaks.
What trees roots grow straight down?
Sinker roots are much smaller roots which grow straight down from the lateral root system to find nutrients. Some species of trees, like weeping willows, eastern cottonwood, and golden bamboo, have very aggressive lateral root systems.

How close does a tree have to be to cause subsidence?
If a tree grows very close (typically within 1.5m) of a lightly loaded wall or structure, then as it grows, the base of the stem or the large diameter roots very close to the trunk may exert pressure and cause it to collapse or lift.
How far should large trees be from a house?

- Buckling in the floor’s surface.
Can removing a tree cause foundation problems?
Removing a tree that has sent invasive roots around or under your foundation causes the soil to rise. This “upheaval” is due to the fact the water that was previously taken up by tree roots is now allowed to percolate into the ground. In rare cases, upheaval can lead to foundation flooding or erosion.
How deep do foundations need to be near trees?
In general, 80-90 per cent of all tree roots are found in the top 600mm of soil and almost 99 per cent of the tree’s total root length occurs within the topmost 1m of soil, with some variations depending on soil porosity.
Which plants can damage foundation?
Poplars, Cottonwoods and Aspens (Populus): These seek out water with their wide-spreading root systems. They are one of the worst to plant near homes. Silver Maple (Acer saccharinum): Shallow and dense roots can invade foundations.

Will removing tree stop subsidence?
If the trees are removed their roots will no longer extract moisture from the soil and it is possible that ‘heave’ could occur. As we have said ‘subsidence’ in clay soils tends to be cyclical with shrinkage and expansion taking place on a seasonal basis.
How far should a tree be from a house UK?
Having said this it is not wise to plant a tree that has the capacity to grow to beyond 20 feet within 10 metres of a building. Tree roots want an equal blend of both oxygen and water in which to thrive and colonize.
