Triton’s TT Super Admix has been used to produce 900m³ of watertight concrete, specified for the construction of the basement at the new DMC Building at Goldsmiths College.

Triton TT Super Admix was 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 is being 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 are to be waterproofed with Triton’s TT Swellmastic and TT Waterstop forming a completely watertight concrete system. Typical cross section detail.

A twin waterproofing 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 – will be backed up by an internal cavity drain system which will be installed when the watertight concrete construction is complete.

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.

The 300ml floor slab was poured in four stages.

Triton’s Trimol epoxy systems offer a fast and effective method of repairing and upgrading structural timbers, whilst at the same time retaining the existing bearing configurations. Normally the external appearance of the original timbers can be maintained, therefore these systems are particularly suited to repairs in historic or listed properties.

Triton approved contractor, Peter Cox Ltd, was contracted to carry out an extensive programme of structural timber repairs in a six storey former dockside warehouse complex in Liverpool, which is being converted into recording studios. Decayed principal rafters and tie beams at roof level and floor beams on all floor levels were cut back to sound timber and new replacement timber installed.

Reinforcing steels were bedded into the new timber sections using Triton’s Trimol 36, a three-component, pourable, epoxy resin system which creeps sufficiently under loading to accommodate movement in complex timber joints.

The team also used Triton’s Trifix Adhesive, a two-component, epoxy resin system to anchor the steels into the end grain of existing timbers. In total 20 roof trusses and nearly 100 floor beam ends were repaired in this way. The technique avoids the need for unsightly steel reinforcement plates and means that the repairs are largely unobtrusive – important when structural timbers are left exposed, as is common in these conversions.

Triton’s Trimol 54 was also used to face off the repaired timber. A two-component epoxy system, it cold sets to form wood-like material, which can be shaped and grained to match the timber being repaired.

A new basement was dug beneath a four storey Victorian property in London and waterproofed with Isola Platon cavity drain membranes and Triton’s TT Vapour Membrane. Providing space for a home cinema, large bedroom suite and plant room, the property is being used as a showcase for similar projects by developers, Michael James Gallagher Projects Ltd.

R & D Management Ltd specified a Platon cavity drain membrane system to the walls with Aqua Channel drainage conduit around the perimeter discharging to sumps to the front and rear of the property. Cavity drain membranes work on the principle of allowing water to continue to penetrate the structure but control it in the air gap and divert it to a suitable drainage point. They do not allow pressure to build up against the internal construction and the air gap behind the membrane allows the structure to breathe. Once the membrane has been fitted, wall surfaces can be dry lined or plastered directly and floors can be screeded or a floating dry board system installed.

The Platon system was installed by MGA Contracts Ltd. As an alternative to using a membrane to waterproof the floor, and to facilitate the installation of under floor heating, two coats of Triton’s liquid-applied TT Vapour Membrane were laid to the floor slab. Sand blinding of the surface provided a key for the subsequent levelling compounds before the installation of the heating system and the feature wood floor.

In addition to its own training courses, Triton also offers training courses which are given by independent industry specialists. The Technicians Foundation Training Course is presented for Triton by the renowned industry consultant, Mr. Graham Coleman, who has over 30 years of investigative and laboratory experience. It is especially suitable for those requiring an introduction to the causes and treatment of dampness and timber infestation, and is especially suitable for technicians.

The next Technicians Foundation Course will be held on Thursday 28th May at Triton’s HQ in South East London.

The course consists of three parts: the first is an introduction to rising dampness, chemical damp proofing, installation and performance of different systems, replastering and performance of replastering systems. The second part deals with the control of rots in buildings and the control of woodworm, materials and methods. Finally a section is included on Health and Safety for the Technician.

This is an independent course and not related to Triton’s or any other manufacturer’s products. Dates and venues for this course are listed on the Training Course booking form  which can be downloaded below. Please complete, print out and return to Triton with your payment of £140 plus VAT per delegate (includes coffee, tea and lunch).

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.

Alan Magee established Thorburn Preservation in 1997.  The company specialises in all types of remedial building works and uses exclusively Triton Chemical’s range of damp proofing and timber preservation systems.  Alan’s team often works in ancient or historically interesting buildings so it was not unusual when he was summoned to Sir William Turner’s Almshouses in Kirkleatham, by architect, Hugh Massey, who had spotted evidence of infestation in several ancient timbers.  Built in 1676, the almshouses still provide accommodation to elderly residents in a complex of cottages, apartments and common areas which are built around a small chapel.  The chapel was remodelled in 1742 and features one of the most unusual ceilings Alan had ever seen.  From below, its vaulted shape appears to be of stone construction, but once in the roof space, it’s obvious that the ceiling is formed of curved wooden lathes which have been plastered with horse hair plaster and decorated to give the effect of stone work.

Thorburn Preservation were contracted to spray all the timbers in the roof space, including the huge 12″ and 18″ oak baulks, the bell tower and adjoining attics.

Due to the proximity of the living accommodation, Alan recommended the use of Triton’s Tritect 121, which is a completely non-hazardous water based system, designed to treat all types of timber affected by wood boring insects.  Tritec 121 is designed to penetrate the timber very quickly and offers a one hour re-entry time.

Before he left the site, Alan was also asked to spray one more item with Tritec 121 - an ancient Jack Hobbs cricket bat, which was infested with woodworm, and belonging to the late husband of an elderly resident!

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.
