Subsidence Reports


SUBSIDENCE IS A CHANGE IN THE CONDITION OF THE GROUND ON WHICH A BUILDING IS SUPPORTED. THIS CAN RESULT IN CRACK DAMAGE APPEARING IN WALLS AND CEILINGS OF THE PROPERTY. IN LONDON AND THE SOUTHEAST THIS DAMAGE IS MOST COMMONLY CAUSED TO BUILDINGS FOUNDED ON SHRINKABLE CLAY SUB-SOILS DURING VERY DRY WEATHER CONDITIONS. MAINLY AS A RESULT OF EXTRACTION OF MOISTURE FROM THE CLAY BY ROOTS FROM TREES AND LARGE SHRUBS, THE CLAY SHRINKS AND THE BUILDING SUBSIDES.

When Subsidence of a building occurs, a careful and thorough investigation by experienced Chartered Structural Engineers and Surveyors is required to accurately assess the area of foundation movement and establish the precise cause. Once this has been established then a course of action can be decided and the correct remedial action taken.

Since 1976 the Chartered Structural Engineers and Surveyors at Angell Thompson & Partners Ltd have been successfully addressing subsidence damage to domestic and commercial properties. As a result we have built an unrivaled wealth of experience and a highly regarded reputation in this very specialised field. As panel Engineers for several of the leading Loss Adjusters we have also for the last 15 years provided an independent opinion on Subsidence causes and remedies direct to Insurers.

Once a Subsidence problem has been initially appraised our good working relationship with experienced site investigation Contractors enables us to quickly establish the cause of movement. Having established the cause a concise and clear report with recommendations for remedial action is then prepared and issued.

Dependant on the level of damage that has occurred and the ability to address the underlying cause a period of monitoring is normally required to establish stability of the building. Once the building is stable then remedial works are specified so that those can be completed by experienced Contractors. Such works can range from simple super structure repairs and redecoration to more extensive works by way of underpinning if the building cannot be stabilised by other means.

At Angell Thompson & Partners Ltd we have the experience and knowledge to provide the complete range of services following Subsidence damage from an initial report through to overseeing all of the remedial works.
