Root Protection Areas: No Go Zones?

The British Standard (BS5937: Trees in Relation to Construction and Demolition – Recommendations) sets out that the radius of an RPA from a tree is calculated as twelve times the diameter of that tree as measured at 1.5m high. Inevitably…

However, they are crucial for your plans to achieve planning permission and to provide the information that the LPA need…

Validating Gas Membranes

Gas proof resistant membranes are installed to provide protection against harmful ground gases, including; methane, carbon dioxide, volatiles, hydrogen sulphide, carbon monoxide and radon gas, from being drawn into buildings by the pressure difference that exists between the inside and outside. These gases can accumulate to dangerous concentrations and should therefore be prevented from effecting…
