How To Treat Damp Problems In A Listed Building

Newton have treated damp in many listed buildings including Windsor Castle

When waterproofing or damp proofing a listed building it is important to adhere to Listed Building Regulations. Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990, states that "no person shall execute or cause to be executed any works for the demolition of a listed building or for its alteration or extension in any manner which would affect its character [emphasis added] as a building of special architectural or historic interest, unless the works are authorised ".

The fundamental challenge when dealing with buildings of special architectural or historic interest is therefore to maintain structural and aesthetic integrity, whilst remaining sympathetic in the product application and still achieving the desired effect.

Newton offer damp proofing and cavity drain membranes which are ideal for listed buildings and can be installed to be reversible – do contact us about your project and we can advise on the most suitable products.

Advantages Of Applying Damp Proofing or Cavity Drain Membranes

The Newtonite System for damp proofing, and the Newton CDM System for below ground scenarios can be sympathetically applied with little or no preparation at all and depending on the chosen wall finish, often only require the very minimum of strategically placed fixings to hold the membrane in place. 
Newton Waterproofing and Damp Proofing Systems have been used in many notable Grade I and Grade 2 Listed Buildings including: 

Grade 1 Listed Buildings

British Museum, London
Reform Club, London
St Georges Hall, Liverpool
Windsor Palace, Berkshire 
Houses of Parliament, London

Grade 2 Listed Buildings:

Ixworth Abbey, Suffolk
Douai Abbey , Berkshire 
Kings College, Taunton
Royal York Hotel, Bath
Wallis House, Middlesex

And Outside The UK:

Menin Gate, Ypres
Limerick Court House

Case Study: The Royal Courts of Justice

This Grade I listed structure had a labyrinth of unused basement areas. With space at a premium, a large part of the brick basement area was converted into habitable space. 

A full Cavity Drain System was installed by a Newton Specialist Waterproofing Contractor, Stonehouse Basements. The System was quick to install and sympathetic to the structure, making it the ideal waterproofing solution.

The convoluted Victorian Bird Beak Arches were sympathetically waterproofed whilst retaining the original features of this historic property, thus meeting Listed Building Requirements. The vaults are now fully refurbished and provide a habitable area to Grade 3 of the environmental table within the British Standard 8102:2009 Code of Practice for Protection of Below Ground Structures Against Water From The Ground.

Following the success of this project, Stonehouse Basements was commissioned to complete a second area to the same specification, with plans to renovate further areas of the immense below ground infrastructure in the future. 
“We were delighted to be involved again in the next phase of this development, following the success of the first phase a few years ago. Newton System 500 is very suitable for listed buildings and meets the stringent requirements for waterproofing structures of this stature”
