Triton News

Triton has worked in partnership with Watertight International in the development of part of Watertight’s ‘Total Flood Protection System’ which was launched officially at the House of Lords on February 12^th.

Responding to climate change, the Watertight International Flood Protection System was launched to provide total protection to property that is at risk of damage by flooding. Developed to surpass British Standard PAS 1188 2009 and the only product on the market to achieve this accreditation, the Watertight International Flood Protection System creates a new generation of flood protection products.

“Our patented system is based on the simple premise that if every means by which water might enter your home is blocked effectively, then your building and its contents will remain as safe and dry as possible,” explains Peter Mooney, chief executive for Watertight International.

The Watertight International Flood Protection System comprises three elements: flood barriers that fit over doors and windows; non-return valves to prevent backflow from outside drains; and wall sealants for brickwork. Each element can be purchased separately, but when used together as a complete system, protection of the property against flooding is at a maximum level. Full details of the Watertight International Flood Protection System can be found at www.watertightinternational.com

The Watertight International range of wall sealants

Triton has launched a new water based Concrete Hardener & Sealer which, once applied,increases surface abrasion resistance, dustproofs, hardens and totally seals the concrete surface.

More detailed information is available from the triton-concrete-hardener-sealer-data-sheet and msds-triton-concrete-hardener-sealer which are downloadable here.

Triton’s TT Vapour Membrane has been used by Ward Damp Proofing to waterproof both the new and existing concrete floor slabs throughout the basement at Bethnal Green Town Hall. An important factor in the system’s selection was its ability to be applied over surfaces where there are traces of asphalt – which can lead to compatibility issues. Read the full case study here….

A twin waterproofing system comprising Platon membranes and Triton’s TT Vapour Membrane was installed to waterproof existing and new basement areas in a very high specification development in South West London, which included a below ground level swimming pool, gymnasium and snooker room.

BS 8102 (2009), the Code of Practice for protection of below ground structures against water from the ground, was published in November 2009 and is available for purchase from the BSI bookshop.  Use this link to purchase the document in either PDF or hard copy format. The revised standard replaces BS 8102 (1990).  There are significant revisions and it is recommended that anyone involved in structural waterproofing and basement construction obtains a copy as soon as possible.

STOP PRESS:  While other properties in the area were flooded, the basement described below remained dry and watertight during the severe flooding in Cork during November 2009!

Triton has supplied an internal cavity membrane system to waterproof the basement level of a major new retail, office and accommodation development at Halfmoon Street in Cork. The site is located just ten metres from the city’s tidal River Lee. 3,000 square metres of Platon P20 has been laid to the floor and 210 linear metres of Platon Multi installed to the 5m walls of the new basement. Triton TT Vapour Membrane was also applied to the concrete slab below the P20 membrane to prevent calcification.

The Platon Multi cavity drain membrane was fixed to the sheet piling walls using an ITW nail gun with depth sensor shot, firing steel pins to a maximum depth of 8mm into the 12mm sheet piling.

The membrane system was installed by Tony O’Hea’s Cork based company, Triton Conservation Systems. The company has been involved with all types of conversation work for 25 years including dry rot treatment, timber preservation as well as structural waterproofing to basements using Platon membranes which are supplied exclusively in Ireland by John Banford of Triton Ireland Building Protection Ltd.

The main contractor on this site is Bowens Construction and Triton Conservation Systems were contracted to O’Callaghan Developments.

STOP PRESS!!!   While other properties were flooded, the basement offices described below remained watertight and dry during the recent severe flooding in Cork during November 2009!

Platon cavity drain membranes were specified to waterproof the basement offices of the luxury Jurys Hotel in Cork built alongside the city’s River Lee.

Specified by building engineers, Niall Fitzsimon & Company, the membrane system was installed by Tony O’Hea’s Cork based company, Triton Conservation Systems. The sheet piled walls in the basement were lined with block work and Platon Multi membrane was fixed directly to the face of the block work using Platon Brick Plugs.
Platon Multi is a 5mm thick polypropylene membrane which provides a fast track solution for structural waterproofing of internal walls and floors. In this instance it was used in conjunction with Platon P20 membrane, laid to the floor to provide high capacity drainage with its deeper stud profile. Both Platon Multi and P20 membranes are impermeable to water, gas and water vapour.

To control any water which enters the basement behind or under the membranes, a Triton Drainage System was also installed comprising PVC Aqua Channel around the perimeter of the floor and a Triton Aqua Pump and Sump. The sump was located into the floor with the removable, structural lid finishing flush with the floor level. The submersible pump was then installed inside the sump and is controlled by an automatic integral float switch. Two 12V Battery Back-Up pumps were also installed. The pumps are discharged to an independant outlet running separately from storm drains.

Triton Aqua Pumps should be regularly maintained and Triton Conservation Systems are contracted by Jurys to provide a twice yearly maintenance inspection to the drainage system as well as for 24 hour emergency call out.
The new basement, used as office accommodation for the hotel staff, has remained completely dry since its completion, in spite of its very close proximity to the river.
Triton Conservation Systems undertakes all types of conversation work including dry rot treatment and timber preservation, as well as structural waterproofing using Platon membranes which are supplied exclusively in Ireland by John Banford of Triton Ireland Building Protection Ltd. The main contractor for this project was Bowen Construction for O’Callaghan Properties, who lease the building to Jurys.

This high specification new build development in North London comprises two dwellings, each with a two level basement, detailed as per the CAD detail here. The lower basement level of each property incorporates a swimming pool. A twin waterproofing system was specified to guarantee a watertight basement for each property. An in-depth crystalline concrete waterproofing admixture was incorporated to the concrete mix and waterstops to the construction joints as the primary method of waterproofing.

The secondary waterproofing system comprised the installation of 800m2 of Platon Multi cavity drain membrane to walls, and 800m2 of heavier duty Platon P20 cavity drain membrane to the lower basement floors. In areas where it was inappropriate or impossible to install a sheet membrane system (such as soffits, car lifts, roof deck and service trench between the two properties, Triton TriSeal and Triton TT Vapour Membrane was applied as an alternative. On the upper basement floor level, the cavity drain system drains into the lower system and then to discharge points - in this case six sumps with double pumps in each, monitored by dual assist control panels and telemetric alarms.

Contractors, MGA, installed the secondary waterproofing system and were able to source all elements from a single point of supply – Triton Chemicals.

DMC Building, Goldsmiths, University of London – Waterproofing phases I and II now complete

Triton has supplied both elements of a twin waterproofing system in the construction of the basement at the new DMC Building at Goldsmiths, University of London.  This approach was proposed by City Basements (Toureen Mangan) and Triton and accepted by the architects, Stride Treglown of Bristol and main contractor, Willmott Dixon Construction.

Therefore the Triton watertight concrete system - the primary method of waterproofing – has been backed up by a Platon cavity drain system which was installed after completion of the watertight concrete construction.

Triton’s TT Super Admix was used to produce 900m³ of watertight concrete, added at a rate of 4.1kg/m3 to a mix of 20% PFA blend (minimum cement content 350kg/m3). The concrete was supplied by Hansons Concrete and used in the construction of the concrete capping beam to the top of the piles, the reinforced concrete liner walls (150mm - 200mm) and the reinforced concrete floor slab (300mm). All construction joints to the capping beam, wall capping beam, wall/floor and floor/floor joints were waterproofed with Triton’s TT Swellmastic and TT Waterstop forming a completely watertight concrete system. Typical cross section detail.

The 300ml floor slab was poured in four stages.

Phase II of this waterproofing project involved the installation of a cavity drain membrane system. Although Triton’s TT Super Admix had been incorporated to the concrete as described above, plus TT SwellMastic and TT Waterstop to the construction joints; when this type of system is used alone, it can still be compromised by shrinkage, thermal cracking and poor joint detailing, leading to leaks which need to be repaired - and the leaks will only become apparent when water comes to bear on the structure.

Platon Cavity Drain Membranes were therefore specified as the second element to provide the extra security of a twin waterproofing system.

800m2 of Platon Multi was applied to the walls and 1800m2 of deeper studded Platon P20 to the floors. 300 linear metres of Triton Aquachannel (drainage conduit) was laid to direct any water which may ingress behind the membrane to the sumps.

The basement will house two lecture theatres, TV and photographic studios and associated areas. The basement is 4.5m deep and extends to the complete 1800m² footprint of the new, two storey building above.
