Earth retaining walkways waterproofed with TT Vapour Membrane

Landscaping at high spec apartments waterproofed by Triton Ground level landscaping, walkways and balconies at a multi million pound London apartment block have been have been waterproofed using Triton’s elastomeric TT Vapour Membrane. The balconies to all floors were waterproofed with TTVM before finishing, and the liquid applied product was also used as a waterproofing layer below the soft landscaping and paved terrace above the residents’ car park. (The car park was constructed below the block using a watertight concrete system, comprising 450 m3 of concrete waterproofed by the inclusion of Triton’s TT Super Admix – Type B waterproofing as defined by BS 8102 2009 and Triton’s associated construction joint sealing products).

On the walkways, Triton Fillet Seal was applied to any internal angles to provide a smooth transition between horizontal and vertical surfaces that can be prone to settlement/movement and possible cracking. Then two coats of TT Vapour Membrane were applied from the earth retaining wall, across the walkway and up and over the internal concrete upstand to provide a waterproof substrate. A concrete ramp was then constructed over it leading to the entrance lobby. A walkway at the rear of the building providing maintenance access has been treated in the same way but has a Breedon Gravel path laid over it. This gravel is a self binding type which, when compacted, knits together to form a surface that is less susceptible to spreading and separating like loose chippings. It is therefore ideal for application on cycle ways, driveways, college pathways etc as well as in residential areas. The gravel was applied over the TT Vapour Membrane which forms a fully bonded waterproofing system.

Triton TT Vapour Membrane provides an effective waterproof membrane which bonds to porous or non-porous substrates. It is flexible and can be painted, plastered or screeded over. The membrane cannot be punctured as it is fully bonded. Two coats are normally required and the fast drying time means both can usually be applied the same day. TT Vapour Membrane can be applied by brush, roller or airless spray and can also be applied to damp or ‘green’ substrates.

Tri-Seal, Triton’s liquid applied damproofing and waterproofing system, was specified as a guaranteed method of waterproofing to protect the servers in two major new data centres.

The servers will be located at ground floor level within the converted facilities. A total of 19,500m2 of Tri-Seal has been applied as a bunded floor finish over the concrete floor slabs constructed at first floor level.

All concrete surfaces were cleaned, ensuring all joints and cracks had been filled with Triton Fillet Seal. Triton Fillet Seal was also used at the junction between the floor slab and the bund walls.

Following preparation of the surface Tri-Seal was applied in a two coat application at a rate of 4m2/kg for the first coat and 5m2/kg for the second coat giving a total film thickness of 400 microns. The coverage rate of the first coat can vary from the above depending on the porosity of the surface to which is applied. Tri-Seal can be recoated approximately six to eight hours after the first coat application and is touch dry in approximately four to six hours. It is fully cured after seven days.

Where Tri-Seal is applied to bunded areas beneath raised access floors to prevent downward moisture ingress, drainage access points are either incorporated into the floor or the water is retained until it can be pumped out.

Tri-Seal is a solvent free, two part epoxy resin formulation, which can be used in a variety of applications.  In addition to application in bunded situations, it is also suitable for application on damp surfaces such as sand/cement and concrete floors subject to rising damp or containing residual construction moisture. The cured product provides a flexible, but tough barrier suitable for foot or light wheeled traffic.  It can be screeded or blinded with course aggregate as a key for renders, bonded screeds or tiles or with fine aggregate as a slip resistant finish.
