Summary

Newton System 800 used to damp proof a school in Brighton which required multiple damp proofing treatments as part of its refurbishment. Installed by Newton Specialist Basement Contractor CavityTech.

The Project

St Mary’s Hall in Brighton is a prestigious private school which required multiple damp proofing treatments as part of its refurbishment. Miller Bourne Architects, in conjunction with Newton’s technical department, put together a scheme to successfully damp proof the building using a portfolio 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 Solution

The building required treatment for driving and penetrating moisture as well as rising damp. The different construction elements within the structure and the space constraints needed to be considered when designing the damp proofing solution. BBA certified Newton 803 Mesh (dimpled meshed membrane) was mechanically fixed to the substrate using Newton Mesh plugs. The dimples face the damp structure producing an air gap which allows for moisture to move behind the membrane.

In addition the membrane provides a physical barrier to prevent staining to new surfaces which is often the case when heating up structures after the refurbishment process. Nitrates and sulfates are prevented from passing through to the new finishes without the need in injected a chemical damp proof course. Cavity Tech Systems Ltd were able to liaise with the main contractor, architects and Newton Technical on a daily basis to overcome any issues that arise when dealing with historic building restoration guidelines.

The Result

The use of the Newton Membranes offered a sympathetic approach to the listed building and is deemed reversible in accordance with listed building guidelines.

The Newton System 800 was easily installed in a timely manner enabling the project to move forward at a pace without the need for drying out time. We were able to provide the client with an insured backed guarantee for damproofing this historic school.
