A green roof for Shrek and friends!

Tuesday, April 26th, 2011

Platon DE25 drainage and storage membrane has been specified as part of the green roof construction at the new Universal Studios theme park in Singapore!

Occupying about 35,000 m2, the green roof is one of Asia’s largest. Platon DE 25 was chosen as the drainage/water retention layer because the wide structural spans of the immense roof and the fast track construction of the park demanded that the chosen system was light and easy to install.  The other components of the green roof build up included a fully adhered layer of Evalon PVC-EVA terpolymer waterproofing membrane, and a non-woven filter fabric which was laid over the DE 25, followed by a primarily inorganic substrate and selected drought tolerant plant species which require little or no maintenance.

The excellent insulation properties of green roofs mean they act as heat and sound shields, protecting building interiors from the tropical heat and reducing sound transmission. This not only reduces energy consumption, but also extends the lifespan of the waterproofing on the roofs.

Triton is the exclusive distributor of Platon DE 25 in the UK and Ireland. Read more about green roof construction here.

Triton systems make concrete lift pits watertight

Tuesday, April 26th, 2011

Togher Construction used concrete waterproofing systems from Triton to provide five below ground level, watertight lift pits for a new build housing project in Hertfordshire.   Working closely with concrete supplier, London Concrete, the Triton team calculated the the required dosage of their TT Super Admix (4.1kg/m3) to guarantee a watertight concrete system which also incorporated Triton’s TT Waterstop and Swellseal Mastic construction joint products.  TT Super Admix is a unique chemical treatment for the waterproofing and protection of concrete – and is designed to be used as an admix at the time of batching. The active chemicals react with fresh concrete to generate a non-soluble crystalline formation which seals the concrete itself against the penetration of water or liquid, protecting it from the deterioration effect of harsh environmental conditions.  Triton’s  TT Waterstop (a pre-formed waterstop) and Swellseal Mastic  (sealant) were installed to protect all critical below ground construction joints, and can be seen in situ in the above image prior to the concrete pour. All critical work on site was overseen by Triton’s technical team.

TT Vapour Membrane delivers quick drying , low height waterproofing in library refurb

Tuesday, April 26th, 2011

Two coats of Triton’s TT VapourMembrane were applied by Ward Damp Proofing to the existing 280m2 concrete slab in the refurbishment of Wood Library in West London.  TT Vapour Membrane met the requirement for an effective, rapid drying damp proof membrane without exceeding a thickness of 4mm, which would have affected existing thresholds.

The TT Vapour Membrane was lapped up to meet the newly installed dpc level to provide a totally damp free substrate ready for the application of a specialist polymer modified screed, and subsequent various floor finishes.

Since completion of the project the building has been transformed into a modern community library and children’s centre, where effective waterproofing was of paramount importance due to the nature of the building’s use.

TT Vapour Membrane is a single component, water based elastomeric liquid rubber membrane, which can be applied by brush, roller or airless spray. In normal conditions two coats can be applied in the same day. In addition to providing an effective waterproof membrane TT Vapour Membrane also provides a UKAS approved gas barrier (Methane, Radon and Carbon Dioxide).

The project – step by step:

All traces of Bitumen were grit blasted from the slab

Prepared slab with chemical DPC injected and walls replastered

Slab vacuum cleaned ready to receive TT Vapour Membrane after grit blasting and Fillet Seal applied to wall/floor junction

First coat of TT Vapour Membrane applied as a primer to second coat

Applying the second coat of TT Vapour Membrane

Epoxy primer laid over TT Vapour Membrane prior to specialist Flowcrete screed

After application of specialist latex screed

TT Vapour Membrane, epoxy primer and latex screed visible at wall/floor junction

Interior fit out after refurbishment

John Longdin, who lives in Chadderton, Oldham, secured the Student of the Year Award in the Property Care Association’s highly specialised Certificated Surveyor in Remedial Treatments examination (CSRT).

The award, sponsored by Triton, was presented to John by Triton’s Business Manager, Kevin Dodds, at the PCA’s awards event, held at St James’ Park – home of Newcastle United FC.

John, 43, works as a damp and timber surveyor at Middleton-based Classic Construction in Towney Street, Middleton, part of the nationwide Bar Preservation group.

Noted for its training and technical expertise, the PCA represents the UK’s structural waterproofing, damp control, timber preservation, structural repair and flood restoration sectors

Stephen Hodgson, general manager of the PCA, said: “This award reflects the high standards John brings, not only to his company, but the building preservation industry in general.”

John added: “I was very pleased, surprised and honoured to win the award. The qualification carries a lot of weight in the industry and to be rewarded with the highest marks is very gratifying.”

Combination system used to waterproof 2000 sq ft basement

Friday, April 1st, 2011

Surrey based Main Contracts Ltd used Platon membranes as part of a combined barrier and drained system to waterproof a new 2000 sq ft basement constructed under an existing building. The existing building was underpinned and then the perimeter of the new basement was contiguously piled with a capping beam at the top to form a permanent support to the adjoining land and to form the structural shell. The basement was then excavated to formation level and drainage and sumps installed.

The new 2000 sq ft basement was contiguously piled

Then a reinforced concrete slab was placed and the walls were sprayed with concrete to give a good surface on which to fix the cavity drain membranes. Steelwork was then installed to support the ground floor concrete slabs.

Once the roof of the superstructure was in place, the Platon cavity drain membranes were installed to complete the waterproofing.  Plato P20 was laid to the floor while a combination of Platon Multi and Platon P5 was fixed to the walls.

Insulation, underfloor heating and screed was then added to the floor and insulation and studwork, together with feature brick walls, were added to the interior.  Part of the new basement is covered with a patio and terrace together with a large, walk on glass roof light.
