Sealing around beams with TorchOn Tanking Membrane

Visqueen TorchOn Tanking Membrane is a heavy duty waterproofing membrane for above & below ground applications, in both vertical and horizontal situations. This photo gallery shows the benefit of TorchOn membrane versus any polymeric or SAM system.

Visqueen TorchOn prevents the ingress of water and is ideal for use in cold weather conditions due to the hot bonding (torch bonding) installation process. The use of hot bonding in cold and sub-zero temperatures provides a homogenously sealed junction, which can otherwise be difficult to achieve in cold weather.

These photos show a good method of application when sealing around beams with TorchOn Tanking Membrane, it certainly shows the benefit of torch on versus any polymeric or SAM system.

These images are part of a large housing development by Birch Homes. They show a high level of application and show our products correctly installed. Continue reading

Visqueen TorchOn Tanking Membrane – A heavy duty waterproofing membrane

Visqueen TorchOn Tanking Membrane is a robust waterproofing membrane, used for heavy duty tanking and gas proofing applications. It can be used both vertically and horizontally above and below ground level to prevent the ingress of water.

  • Robust tanking membrane
  • Suitable for gas protection applications
  • Torch bonded laps provide a homogenously sealed junction
  • Ideal for cold weather application
  • Used to waterproof basements, car parks, lift pits, reinforced concrete slabs, retaining walls

Visqueen TorchOn Tanking Membrane should be applied as a two layer system when used as a tanking system for below ground structures where high levels of hydrostatic (water) pressure exist in conjunction with an internal waterproof render in accordance with BS8102: 2009 type A structures.

Visqueen TorchOn Tanking Membrane can be used as a single layer system when used as a horizontal damp proofing membrane or in low risk situations. All laps should be a minimum of 150mm. The loading screed or floor slab which is laid on top of the membrane should be adequate to resist any hydrostatic water pressure.

Visqueen Gas Protection Systems supplied for prestigious Library of Birmingham project

Client:             Carillion
Location:       Library of Birmingham
Date:               June 2013
Sector:            Education

About the project:

One of the most prestigious projects that Visqueen Building Products supplied products to in 2013 was the Library of Birmingham in the city’s Centenary Square.

The library is situated in one of the city’s most important public open spaces in the heart of Birmingham city centre’s Westside.

The new library features many innovative design and construction techniques. It has two elevated outdoor garden terraces which offer an environment for visitors to unwind, socialize and learn, as well as bringing environmental benefits through offsetting carbon emissions and attracting wildlife and local ecology.

Key facts

  • Opened in September 2013
  • Overall building cost – £188.8 million
  • Main contractor – Carillion
  • Designer – internationally acclaimed Dutch architects, Mecanoo
  • Expected to attract around 3.5 million visitors annually

Project challenges:

The build site was contaminated with CO2 gas, which posed a key challenge for Carillion as a specialist gas protection system would be required to make the development safe for construction. As a leading technical authority in the provision of gas protection systems, Visqueen was called in to provide knowledge and expertise in specifying the correct gas and damp protection solutions for the site conditions.

Visqueen worked closely with site managers and personnel, providing consultative support throughout the project. This involved advising on the correct products and system accessories, supplying accurate CAD details and overseeing installation.

Chris Hayes, Technical Support Manager at Visqueen who worked with Carillion on site explains further:

“We supported the team from start to finish, ensuring that all gas and waterproofing products were installed in accordance with the latest building regulations, and we were able to provide technical sign off of the finished installation.”

Michael Heir, Masonry Advisor at Carillion Technical Services commented:

“The decision to use Visqueen Zedex High Bond DPC to waterproof the base of the cavity at Birmingham Library proved correct. Visqueen technical support at Birmingham Library was excellent.”
