St Mary’s Hall is a prestigious private school in Brighton that required several damp proofing treatments as part of a refurbishment.
Miller Bourne Architects, in conjunction with Newton’s technical department, designed a scheme to damp proof the building using a suite of Newton materials.
Newton Specialist Basement Contractor Cavity Tech Systems Ltd was commissioned to carry out the works as they have extensive experience of damp proofing Brighton properties.
The building required treatment for driving and penetrating moisture as well as rising damp. Different construction elements within the structure as well as space constraints needed to be considered when designing the solution.
Newton 803 Mesh, a BBA certified, dimpled meshed membrane, was mechanically fixed to the substrate using Newton Mesh plugs. The dimples face the damp structure and create an air gap that allows moisture to move behind the membrane.
The membrane also provides a physical barrier to prevent staining new surface finishes, which often happens when structures heat up following the refurbishment process. Nitrates and sulfates are prevented from passing through, without the need to inject a chemical damp proof course.
Cavity Tech Systems Ltd were able to liaise with the main contractor, the architects and Newton Technical on a daily basis to overcome any issues that arose when dealing with historic building restoration guidelines.
The use of the Newton Membranes allowed a sympathetic approach to refurbishing this listed building and is deemed a reversible treatment in accordance with listed building guidelines.
“The Newton System 800 was easily installed in a timely manner enabling the project to move forward quickly without the need for drying out time. We were able to provide the client with an insured backed guarantee for damproofing this historic school.”
