Tree Advice for Engineers, Loss Adjusters and Insurers
JCA has dealt with over 4000 tree related subsidence cases for a range of leading
insurers, loss adjusters and consulting engineers.
Our comprehensive services for tree related subsidence claims include specialized
arboricultural survey, heave assessment, root identification, management/supervision
of tree works contracts (including installation of root barriers), risk assessment
for local authority street trees, and expert witness service for litigating claims.
Arboricultural Survey for Subsidence Claims
Our subsidence survey report is competitively priced and generally completed within
15 to 20 working days of instruction. The report is a comprehensive and easy to
read document with a clear, colour
plan usually printed at 1:200 scale. Digital photographs are supplied to help
illustrate particular trees or problems.
Heave Assessment
Heave, an upward movement of the ground resulting from soil rehydration following
tree removal, is a possibility in some cases but it is not common. Potential for
heave depends on the age of the building compared with the age of the tree, the
nature of the soil and how close the tree is. We are happy to provide advice regarding
heave and where appropriate provide a comprehensive heave assessment.
Litigating Subsidence Claims
Jonathan Cocking is an experienced expert witness with an excellent track record
with both insurance companies and local authorities in litigating subsidence claims.
