New passive ventilation unit from Triton

Saturday, June 4th, 2011

Triton has added the new Ultrovent passive ventilation unit to its range of anti-condensation products.   The triple action filter and specially designed thermal core allow minimal heat loss. Ultrovent is also quick to install and there are no ongoing costs! Extension kits are available to suit all wall thicknesses.

Triton Ultrovent is designed to ventilate bedrooms and living rooms where the constant background ventilation it provides allows water vapour to escape. One air brick ventilator is usually sufficient for a singe room of up to 20m² floor area, alternatively two core drill ventilators can be installed. Each unit is supplied with positioning and installation instructions.

A watertight concrete basement for luxury Wembley development

Saturday, June 4th, 2011

Two 20 storey buildings, one a hotel and the other a luxury residential and commercial apartment block, are being constructed a stone’s throw from London’s Wembley Stadium.  Triton has been appointed by main contractor, Donban Construction, to supply a watertight concrete system (comprising types A and B methods of waterproofing as defined in BS 8102 2009) for the large underground car park which will serve both buildings.

Dig out

The watertight basement measures 80m x 70m x 4.5m deep and is being constructed from 2,000m3 of concrete which incorporates Triton’s TT Super Admix to create a waterproof floor slab and liner wall.

Triton Super Admix is a unique chemical treatment for the waterproofing and protection of concrete – 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, inhibiting the ingress of water through small cracks, shrinkage etc. and protecting it from the deterioration effect of harsh environmental conditions. Triton TT Super Admix is supplied in soluble packs to make dosing easier.

Triton’s technical team worked closely with concrete suppliers, Cemex, and recommended a dosage rate of 4.1kg of TT Super Admix per m3 of concrete.  Triton will continue to provide support and advice to the main contractor and concreting sub contractor (JNC Utilities) as the job progresses.

Preparing to pour the floor slab

Triton TT Waterstop (a water bar) and  Triton TT Swellseal Mastic, will be applied to all concrete construction joints and concrete interface. The application of these products will also be overseen by Triton’s technical team who will monitor and record the application of every waterproofing element of the basement’s construction up to ground level prior to providing a warranty on the system.
