Landmark residential tower makes use of Interflow UK’s specialist solutions

Lillie Square will be one of the most high-profile residential developments in London, transforming a 7.4 acre car park on

Seagrave Road into 808 high-end new homes offering modern garden square living.

The Lillie Square scheme will be built in phases with the overall construction taking an estimated five years to complete.

As part of the development, Interflow UK is supplying a range of specialist solutions from DOYMA. Interflow is the UK

distributor and installer of a specialist range of products for the built environment, designed to enhance, add value and

increase sustainability across commercial and public sectors, thereby helping customers save energy and reduce their

carbon footprint.

DOYMA pipe sealing systems prevent structural damage. Wherever service ducts are installed through walls, ceilings or

floors, penetrating water, other liquids or humidity may cause damage to buildings, DOYMA duct sealing systems ensure

professional and perfect sealing, thus presenting excellent preventative measures against structural damage.

Interflow has been asked to supply and install the 8000 and 8000/T range of sleeves, including welding steel, retrofit sleeves

around service pipes passing through the sheet piling. These sleeves enable sealing on the face of any wall and seal

penetrations without a suitable core bore or pipe sleeve. The inside face of the sleeve provides an optimum contact surface

for the elastomer of the Curaflex gasket insert.

DOYMA’s 8000 and 8000/T sleeves are gas-tight and leak-proof against pressing water and non-pressing water. They are

suitable for buildings without tanking membranes (white tank) or with thick mastic coating with the contact surface “bonding

flange” additionally sand coated to optimize keying. They can be used in conjunction with all Curaflex gasket inserts, also

available from Interflow.

The very best in German engineering is used to seal penetration points through walls and floors to permanently prevent any

infiltration of gases and water into the building, and the DOYMA products are guaranteed for 25 years.

DOYMA’s Curaflex gasket inserts with their unique, asymmetric Double Profile System (DPS) generate a differential contact

pressure by means of asymmetric profiled sealing frames which direct greater sealing pressure outwards to the sleeve or

core-drilled concrete and softer pressure inwards to the ducted service without compromising sealing efficiency.

The unique DOYMA grip is a special elastomer with high adhesive contact on the media pipe or cable. Together, they ensure

optimum and permanent sealing of the service entry while still tolerating axial, radial, angular (settlement & ground heave)

movements with no loss of sealing integrity, thus assuring owners and occupiers quiet enjoyment of their home through

years of trouble-free occupancy.

The one million square foot Lillie Square scheme has Sir Robert McApline (SRM) as main contractor to build the first phase.

The scheme is a joint project between CAPCO and KFI.

CAPCO Capital & Counties Properties PLC (‘Capco’) is one of the largest listed property companies in central London with

two landmark estates at Earls Court and Covent Garden. KFI represents interests of certain members of the Kwok family.

Interests of the Kwok family are major shareholders of Sun Hung Kai Properties Limited, one of the largest and most highly

reputable real estate companies listed on the Hong Kong Stock Exchange.
