- Details of vegetation in the vicinity and its management since discovery of the damage. Include a plan showing the vegetation and affected building
- Measurement of the extent and distribution of vertical movement using level monitoring Where level monitoring is not possible, state why and provide crack-monitoring data
- A profile of a trial/bore hole dug to identify foundation type and depth and soil characteristics
- The sub-soil characteristics including soil type -liquid limit, plastic limit and plasticity index
- The location and identification of roots found
- Proposals and estimated costs of options to repair the damage
Tree planting advice
If you are thinking of planting a tree in your garden and are concerned about it causing subsidence, a qualified arborist can provide advice on species selection and suitable planting distances from your property. Your local tree nursery may also be able to help.
