External Damp Proofing Swansea

John Newton & Company commended by the local council for providing a damp proofing solution which came within their budget and was completed ahead of schedule with no loss to classroom operation

History
This school in South Wales was located in an extremely exposed area to driving and penetrating rain. Moisture subsequently entered the building

fabric damaging internal finishes within the classrooms. An external approach was needed as internal damp proofing would cause massive disruption to staff and pupils.

Methodology
Newlath 2000 meshed membrane was applied externally to the school buildings. Mechanically fixed at 100mm – 150mm centres the meshed membrane was applied and a 6:1:1 clean sharp sand, cement, lime mix was then applied in two 6mm coats. A rubbed float finish was then applied prior to decoration.

Result
The contract was in excess of 250 square metres and the local authority were delighted that the project came within their budget and was completed ahead of schedule with no loss to classroom operation.

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 Newlath 2000. In addition, any further attempts of moisture entering the building fabric is repelled by the membrane system.
Significant U Value benefits are being achieved with the internal of the classrooms being warmer.
No expensive repointing was required.
