In areas where the local geology is made up of shrinkable clay sub-soils, significant structural damage can be caused by tree roots undermining the foundations and extracting water to feed tree growth. Root barriers are installed to stop foundation damage associated with mature trees in close proximity to the structure. They are a physical barrier placed between the tree and the property in question. Root barriers are designed in consultation with our geotechnical team and arborists. The barriers can be installed to depths as great as 4 metres below ground.
Our specialist technique allows a root trench to be safely installed close to an existing building. With care it is possible to minimise damage to the area of installation to an area of excavation no wider than 400mm. Trees are often in close proximity to a home, and the roots can threaten to undermine the foundations. Gardens and drives are always carefully protected to minimise damage during the remedial work. Root barriers are installed to pre-determined depths & lengths, even as close as alongside an affected wall. Where sheet piles are installed, they are then cut off just below ground level and capped with concrete prior to reinstatement of the surface finishes.
Root barriers are available in many forms: steel, copper, fabric, concrete. Our experts can determine the right form, length & depth for each specific project. Expert care is needed to also protect the tree roots to prevent destabilising the tree and causing further potential risk of damage from falling.

Civil & Structural Engineering
Engineering Innovation is at the heart of our approach to structural engineering. Shire were formed during 1988 in the belief that many clients were dissatisfied with the traditional reactive response of some Engineers.Find out more
Shire have a vast array of in-house design skills and expertise. Our dedicated telecoms team are often driving a gold design standard in the industry for others to follow. Our commitment is to provide quality design in a proactive, forward-thinking way & quickly! Our services also include site surveying, building analysis, tower analysis and line of sight surveys.Find out more
Shire originally started the geotechnical service to provide our own engineers with information on site, while the structural surveys were being carried out. This allowed us to offer a reactive, rapid response to our clients as a ‘one-stop shop’ for Design, Investigation and Construction.Find out more
As Structural Engineers, we have worked with the Property Insurance sector since 1998. We conduct structural inspections, impact damage analysis, specialist investigations and root cause analysis. All of which is engineer-led using straightforward language. Our experienced engineers are also asked to conduct Expert Reports and Expert Witness Service for homeowners and clients alike.Find out more
Shire offer a specialist building repair service registered under the Safe Contractor Accreditation and the Contractors Health & Safety Assessments schemes. In conjunction with our inspection & investigation services, we can offer a full solution from initial cause analysis through to structural repair.Find out more
Research & Development
We love a challenge! We were first asked to find a solution for repairing terraced houses in the City of London that had restricted access but needed structural support. That was in 1998 and the Shire Pile was created. Since then the R&D team at Shire have developed more products with a focus on restricted access, concrete-free, easy to install, removable and recyclable for a wide variety of applications. And there are plenty more solutions on the way. Contact us if you have an engineering challenge we can help to solve.Find out more
