Subsidence and Trees

Geobear can prevent structural movement and put an end to subsidence without the need to remove trees

Buildings with foundations in clay soils, close to trees, are commonly affected by subsidence due to the trees’ withdrawal of moisture from the soil. This phenomenon is known as clay shrinkage and commonly results in crack damage to buildings, particularly around window and doorway openings in summer and autumn.

In more highly shrinkable clays, the reverse happens in winter and spring when the return of moisture into the soil results in the closure of crack damage due to clay swelling.
