CASE STUDY

REFURBISHMENT DAMP PROOFING
St Mary’s Hall – Brighton

Newton Damp Proofing Membranes Designed To Damp
Proof Grade II Listed Private School in Brighton

Project Details

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.

Methodology

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 sulphates 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.

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.

Testimonial

Featured Products

NEWTON SYSTEM 800

Newton System 800 is a range of BBA approved damp proof membranes and ancillaries which are quick and clean to install and offer a permanent solution for damp proofing walls.

Newton 805 Newlath is a composite damp-proofing membrane comprising high density polypropylene membrane with a polythene mesh heat welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.
