Damp Proofing Project Pontardawe Swansea South Wales - Curing Aggressive Damp Penetration Externally with Newlath 2000.

Client

Neath and Port Talbot County Council.

History

This School is located in a extremely exposed area which resulted in driving and penetrating dampness hitting the outer fabric of the building and spoiling the internal render and finish to the classrooms. As this local authority has used Newton Newlath 2000 successfully on other school projects, where the same problem existed, they specified Newlath 2000 be applied externally to eradicate this problem. The membrane could not be applied internally because of the disruption it would cause to teachers and pupils.

Methodology

The Newton Newlath 2000 membrane was applied by a Newton contractor with skill and competence as the project required intricate detailing in particular to the window coins.

The fixing centers were generally spaced at 200mm but reduced to 100-150mm in the demanding areas. A 6:1:1 clean sharp sand, cement, lime mix was then applied in 2 coats to the membrane with a rubbed float finish in preparation for decoration.

Result

This contract was in excess of 250 square meters and the local authority were delighted that the project came within their budget and was completed ahead of schedule using the externally applied technique.

The Benefits

The existing substrate which was constantly saturated is now in the process of drying out aided by the 5mm air gap created by the Newton Newlath 2000. In addition any further attempts of moisture entering the building fabric is repelled by membrane.
Great U Values are now being achieved with the membrane warming the interior of the school.
No expensive re-pointing was required.
