CASE STUDY 1
Curing Aggressive Damp In A Grade II Listed Building With Newlath 2000

 

Newlath 2000 Damp Proof Membrane Used To Cure Aggressive Damp Problems

This property had been derelict for a considerable time and had significant house damp problems. House damp of this kind needed to be treated sympathetically, and due to the listed status, English Heritage had certain constraints. They required a system that would be sympathetic to the original structure and that would accept a lime render.

Newlath 2000 was deemed the best solution. The Newton damp proof membrane was deemed removable so was suitable for use on Listed Buildings with damp problems. In this case it was especially advantageous because of its ability to accept lime renders.

CASE STUDY 2
The Solution for Rising and Penetrating Damp in an External Damp Proofing Project

 

Newlath 2000 Damp Proof Membrane used to cure penetrating damp problems in a school in South Wales

This school in South Wales was located in an extremely exposed area to driving and penetrating rain, causing major damp problems and penetrating damp. Moisture subsequently entered the building fabric damaging internal finishes within the classrooms and the penetrating damp was causing major problems. An external approach was needed as internal damp proofing would cause massive disruption to staff and pupils.

Newlath 2000 was used, and the local authority was delighted that the damp proofing project came within their budget and was completed ahead of schedule with no loss to classroom operation.

CASE STUDY 3
Curing Aggressive Penetrating Damp Internally With Newlath 2000

 

Newlath 2000 Used To Solve Penetrating Damp Problems

Newlath 2000 was used to combat severe penetrating damp in a 15th Century building in Berkshire. Due to the severe damp problems, this Grade II Listed Building was uninhabitable and in need of total refurbishment. Newton’s technical department advised to apply Newlath 2000 internally to the external walls and finish with an independent dry lining system. After 2-4 weeks the building had been successfully converted into a complex of luxury apartments free from the effects of penetrating damp.

Newlath 2000 is ideal for this type of refurbishment project as minimal surface preparation is required and the system is totally reversible meaning it is highly sympathetic to the building fabric. The damp proof membrane allows the wall to breathe thus not trapping any previous moisture within the structure.

CASE STUDY 4
Newton 503 Mesh Cures Aggressive Damp Penetration Externally in an Exposed Seaside Cottage

Newton 503 Being Installed To The External Walls

Talmine Cottage is located on the edge of the Atlantic coast. The stone structure was suffering from aggressive moisture penetration from the elements. Driving rain and salt air was forcing its way through the structure. The client had tried repointing the stonework, using traditional lime mortars, but this did not prevent the ingress of damp. An extensive infra red survey discovered that there was no infill of the cavity, which was the traditional means of construction at the time of the build. This meant that the driving rain was soaking through the external stone leaf and filtering through to the internal finishes, without impediment.

John Newton & Company’s technical department recommended installing Newton 503 Mesh to the external face of the building. This would create a physical barrier against the elements and allow the structure to dry out over time. The existing substrate is now protected from further moisture penetration, and the process of drying out the structure was made possible by the 3mm air gap, created by the Newton 503 Mesh.
