Triton supplies ground gas protection system to new build primary school

Friday, February 24th, 2017

Triton Systems designed and supplied a ground gas protection system for a new build primary school site in Bridgwater, on instruction from engineers, Stride Treglown.

Certus Construction Ltd installed the system to protect the site from ground gasses on the contaminated, brown field site in accordance with BS8485, CIRIA 665, NHBC and the Local Authority Ground Gas Handbook.

The system comprised Triton’s TGS-GV25, a 25mm thick, single sided geo-composite that provides a void beneath the floor slab and, when connected to the air venting system, allows sufficient air changes to dilute any gases present. The TGS-GV25 was installed in strips at 6 metre centres across the site and linked to ground level vent boxes before the installation of insulation and Triton’s TGS-HP750 membrane as a gas and waterproofing barrier.

BBA approved TGS-HP750 is a high performance reinforced gas barrier, that incorporates a 12 micron aluminium foil layer, for maximum protection against ground gases. Due to its unique composition, the membrane is extremely robust and flexible and easy to install on site.  As it also provides protection from damp when placed below the slab, there is no need to install a separate DPM.

The steel intense ring beam was treated with Triton’s liquid applied TT Vapour Membrane, which is easily applied around awkward details, before the TGS-HP750 was sealed to it to create a fully sealed gas-proof and waterproof system.

Triton announces 2017 Training Course dates

Wednesday, November 23rd, 2016

Triton has announced the 2017 dates for its popular courses aimed at professionals involved in the installation of waterproofing systems and damp proofing works.  There are also two new courses in the Triton programme next year on Ground Gas Protection and Pumps & Drainage.

The Ground Gas Protection course provides an introduction to ground gases, what they are and where they are found. It covers the relevant standards and associated guidance documents – BS8485:2015, CIRIA 735, 748 and BRE 211. The course also covers site investigation and design of gas protection measures along with an introduction to Triton’s comprehensive range of gas protection products.

The new Pumps & Drainage course has been designed for all involved with the installation of Type C cavity drain systems where pumps and drainage are a critical part of the waterpoofing design. Although this subject is covered in brief in the Type C training course, this new course goes into the subject in more depth, to cover drainage design, selection of pumps, calculating the number and size of pumps required, impact of friction loss, installation of pump systems and commissioning and maintenance.

Courses last one full day and take place at Triton’s head office near Dartford, Kent. They should be booked  using the downloadable training course booking form here Each course takes place throughout 2017 and dates are set out on the booking form.

Further details about all courses offered by Triton can be found on the website.

Triton’s TWS-Fastcoat delivers fast track elastomeric waterproofing

Monday, November 14th, 2016

Triton’s elastomeric, liquid applied TWS-Fastcoat, has provided a rapid drying waterproofing solution for the floor slabs of the subterranean light wells at the Material Store housing development in Hayes.

The material Store development is part of the £250 million regeneration of The Old Vinyl Factory in Hayes, West London, where thousands of people worked for EMI, pressing and packaging vinyl records and making everything from radio sets to bicycles.

The slabs were constructed approximately 1.5m below ground level and although the new concrete incorporated a watertight concrete admixture would have remained gas and vapour permeable.  Two coats of Triton’s TWS- Fastcoat, (which can be applied effectively in ambient temperatures even when substrate temperatures are as low as 0o), therefore provided an impervious barrier which will also lower the potential risks of corrosion of the steelwork in the slabs as well as protecting the outer surfaces.

TWS-Fastcoat is a single pack, moisture curing, elastomeric resin. The membrane cures in a continuous and elastic form, as a totally adhered layer. It guarantees total water tightness and withstands minor building movements and vibrations. TWS-Fastcoat can be used as a base coat, a reinforcing layer or a top-coat. Other typical applications include podium decks, low pitch and flat roof areas with pedestrian traffic, wet rooms, lightly trafficked flooring, water channels and ponds. In green roof applications, the addition of Triton’s geotextile fleece between the two coats of TWS-Fastcoat provides an effective root barrier and waterproofing layer.

At the Material Store development, as part of the preparation for the application of TWS-Fastcoat, Triton’s Fillet Seal was applied in 25mm beads to all internal angles that eliminates 90o angles at wall/floor transitions and minimises the risk of leaving gaps or holes unsealed. It was also important to ensure that the concrete surface was clean and dust free. On porous or friable surfaces, Triton’s TWS-PU Primer should be applied before the application of TWS-Fastcoat.

The slabs will receive raised access floors over the TWS-Fastcoat layer, allowing any potential water/rain ingress to enter the drainage systems of the individual dwellings beneath the raised floor.

Triton supplies Type C waterproofing for landmark London scheme

Thursday, June 23rd, 2016

The White Collar Factory will be a mixed-use area of workspace, residential and retail, designed by architects, AHMM.  The development, sited on London’s City Road, comprises a new 16-storey office tower, a new public square and refurbished existing buildings to the rear.

The new 2-storey basement has been waterproofed using a Type C system applied internally, to provide drained protection in accordance with BS 8102: 2009. The waterproofing system has been supplied by Triton Systems.

During demolition of the existing structure, the sub-contractor (Dunne Group) worked closely with Triton’s CSSW qualified technical team, to design the most appropriate and cost effective waterproofing system that was subsequently approved by all relevant parties as the most suitable protection against potential ground water ingress.  2,000 m2 of Platon P20 cavity drain membrane was subsequently specified for all earth retaining basement walls on both levels and the ground bearing slab at lower level.  BBA certified Platon P20 membrane is a high capacity drainage membrane recommended for use where it is important to significantly reduce the risk of blockages behind the membrane caused by lime deposits.

Prior to the installation of the membrane, all fresh concrete at earth retaining elevations was treated with Triton’s Anti Lime solution. This treatment hardens and dust proofs the concrete as well as locks in free lime to further reduce the risk of blockages in the drainage elements of the system.

Any water entering the construction at upper and intermediate basement levels is gravity drained behind the studded P20 membrane down to a waterproof concrete bund/upstand which provides a 100mm cavity, onto which internal block walls can be built.

A series of 40mm holes at 900mm centres were drilled within the bund to allow any water to drain down behind the membrane installed to the walls at lower level. The bund was also waterproofed with Triton’s cold liquid applied TT Vapour Membrane (TTVM) that will prevent potential damp patches being visible on the internal block wall faces. A band of TTVM was also applied around the perimeter of the lower soffit dressing down behind the P20 membrane installed to the external walls and sealed with Triton Corner Strip (butyl tape).

Bunded detail

In line with the requirements of BS 8102: 2009, removable panels were installed in the bund to allow access to flushing ports. These allow the system to be regularly maintained and flushed through to ensure a clear passage of water is maintained to the sump/pumps that are set within the lower floor slab.

Vertical joints in the Platon P20 were sealed using Platon Sealing Rope and Brick Plugs, with all wall/ floor junctions sealed using Platon Corner Strip Tape – a wider waterproof butyl tape. Platon Sealing Rope was used to seal joints in the P20 membrane that was loose laid to the floor slab.

Water draining from the system to the lower floor slab is drained via gulleys in the slab to the installed sumps. These gulleys also incorporate rodding eyes at approximately 12LM intervals to allow for maintenance of the system.

The P20 membrane on the floor has been screeded over ready to accept finishes and the construction of internal walls.
