There is no denying that trees are a beneficial asset to the environment, our lifestyle and are a symbol of a healthy landscape.

Issues Facing the UK’s Road and Infrastructure Networks

The UK’s road and infrastructure network is in constant need of upkeep and traditional remediation methods are often too slow to keep our networks running in a timely, cost-efficient manner.

Injecting new life into ground improvement

Most subsidence issues in the UK are created by unstable ground, often caused by extreme weather conditions such as hot, dry summers and heavy rainfall or flooding. Other factors such as leaking pipes, vegetation with invasive roots, loosely packed soils or old landfill sites, excavation work and inferior concrete foundations can also be sources of subsidence.
