Subsidence Reports

What are Subsidence Reports?

Subsidence reports identify the cause of any subsidence This includes pinpointing which tree is causing the subsidence and offering recommendations.

Subsidence can be caused by clay soils, which can expand or shrink depending upon the moisture content. This usually occurs due to the trees drawing water from the soil during a dry period of the year. This causes the soil to shrink. As a result, the foundations of any neighbouring properties move and cracks start to appear.

A typical subsidence crack is a minimum of 3mm wide and becomes wider nearer to the bottom. As they develop over time, these cracks can become quite significant and can cause a range of damage as they grow.

The most common causes of subsidence are trees, large bushes or hedgerows. These amount to 60 % of recorded cases. A further 15% of recorded cases are caused by drainage problems.


So, how does it work?

We are happy to work with a wide range of people including insurance companies, solicitors, surveyors, local authorities and loss adjusters. Upon receipt of your enquiry, we will provide you with any advice you may need. We will also arrange for one of our expert consultants to meet you on site.

Within the meeting on site, our consultant will be able to carry out a BS5837:2012 tree survey and survey the surrounding landscape. This will allow them to assess the cause of the subsidence. At this point measurements, photographs and various tests will be taken at the site. Our consultant may request further plans or details from yourself to support the assessment.

Upon completion of the report, you will be provided with a digital PDF pack. This can either be branded under ProHort or provided as a White Label document to incorporate into your own documentation.
