Richardson & Starling
This new build design is split onto two levels and has been constructed out of reinforced concrete panels bearing off a structural raft.
The nature of the build sees the property cut into a sloping site making the back elevations of the project earth retaining down two stories and partially on both flank elevations.
This top spec new build project is “live” on site and will be waterproofed to the highest level of structural waterproofing available - Grade 3 - Habitable Accommodation to BS 8012:2009.
Newton Specialist Basement Contractor Richardson and Starling have curtain-hung the Newton 508 membrane to the re-forced concrete panels using minimal MultiPlug fixings.
This technique meant no surface preparation was required meaning there was a significant cost saving when compared to traditional tanking systems.
Once affixed to the retaining walls Newton 508 terminates into the Newton Basedrain conduit. The Basedrain has been recessed into a 50x80mm rebate allowing the Basedrain to sit level in a horseshoe formation.
Any water that enters the structure is diverted into the Newton Basedrain which will then guide it to the front elevation of the property.
At this point the upper ring main of the Basedrain discharges down behind the Newton 508 on the lower level (see diagram).
Once the water is diverted to the lower level, another horseshoe of Basedrain picks up the water and diverts it to the open elevation at the bottom of the property.
Both slabs are protected with Newton 508 which is then sealed to the upstand of the Newton Basedrain in preparation for a screed with underfloor heating incorporated.
Once the screed is installed the client has a mixture of independent dry lining and lightweight block as an internal finish option.
The installation of the Newton System 500 water management system allows for the highest level of waterproofing protection in the UK.
Richardson and Starling are able to offer full design and installation guarantees for the work and their design omitted the use of sump and pumps.
The Basedrain conduit was installed with maintainable jetting points making the system fully maintainable - a mandatory design requirement in accordance with BS8102:2009.
The Newton System was installed with precision and speed and was not inhibited by adverse weather conditions, as with external systems.
