NEW BUILD BASEMENT

Newton System 500 used to waterproof to Grade 3habitable environment in accordance with BS8102

Project Details

The main contractor O Hare & McGovern were commissioned to build a

brand new school in the Belfast area.

As a part of the major works a new reinforced concrete part basement area

was designed to house the dining hall areas for the student body. Newton

Specialist Basement Contractor Ulster Damp Proong Group (UDPG) were

commissioned by the main contractor to provide a waterproong design

and installation to create a Grade 3 Habitable environment in accordance

with BS8102:2009.

Methodology

Once the reinforced concrete superstructure was built, UDPG installed

the Newton System 500 drained cavity system to all retaining walls. The

membrane was curtain hung with minimal xings and terminated at thewall oor junction. As a means of removing any water that did ingress the

structure, Newton Basedrain was installed into a shuttered of margin of

100mm x 80mm.

The wall membrane (Newton 508) was tucked down behind Basedrain

and, because the property was only retaining on two elevations, any

water ingress could be managed by gravity out to the open elevations on

both anks. As the water was being captured at the wall oor junction in a

margin, a liquid vapour barrier was applied to the oor area.

Benefits

This prestigious project was protected by an internal maintainable

waterproong system which was not dependant on dry conditions - as

is the case with external waterproong options.

The unique dimpled prole of the Newton 508 waterproof membrane

means for ease of jointing the material with no negative pressure

being able to push the membrane of the wall as with internal applied

barrier system.

The open elevations available means no mechanical extraction was

required the ingress could simply be removed via gravity.
