Waterproofing an Extension with Newton 500 System from Bayset

Old Heritage Style Cottage, Cremorne, Sydney
Waterproofing a large new extension

The owner of this old Australian heritage style cottage wanted to modernise the living style and practicality of the house, while retaining the cottage street appeal. Newton System 500 was installed to all new areas.

Project Description
Two new areas were added to the home. 1 - A new timber workshop was cut-in under the existing home. 2 - A new open-plan living area was extended off the back of the home, which was cut into the gently sloping block, and the retaining walls required a moisture control system.

For the workshop area, excavation to allow for an externally applied membrane was not possible due to structural restrictions, and so an internally installed system was required. For the open-plan living area, the owner and architect wanted a future-proof system that would mitigate all moisture ingress risks, including that of rising damp up through the existing concrete slab. The waterproofing system also had to be compatible with in-slab floor heating system. Newton System 500 was the logical choice as it was compatible with all required elements, and would provide the most long-term reliable results.
