Full description


Viega has supplied its German-engineered press connection systems, Profipress and industry first Megapress, to the regeneration of Tollgate Gardens in the London Borough of Westminster. The Viega products, for copper pipe and thick-walled steel tube respectively, provided speed, simplicity and reliability for the domestic water distribution and heating systems.

The new Tollgate Gardens scheme in Maida Vale consists of 198 new-build homes and primarily replaces existing residential blocks constructed in the late 1960s. Specialist M&E contractor Promech was responsible for the design and installation of mechanical services on the ENGIE project. Following an evaluation of the available options, Viega’s Megapress press connection system was selected for use on the thick-walled steel tube heating systems. Viega’s Profipress system for copper pipe was also used on the hot and cold-water distribution pipework across the site.

Greg Martin, M&E Services Manager for ENGIE explained: “For the heating systems we wanted to ensure superior strength, durability and longevity. After contemplating the benefits, our preference was the thick-walled steel over a polypropylene pipe alternative.”

Steve Pearce, Director at Promech Services said: “We were very familiar with press connection systems but had not used them on thick-walled steel before. Following a consultation with Viega’s Technical staff and the M&E team at ENGIE, we were confident that the system met our requirements.”

Megapress was the first system launched to the market to enable thick-walled steel tube with diameters between ⅜ inch and 4 inches to be press connected. It is cleaner, safer and more reliable than traditional installation methods and provides between a 60% and 80% time saving when compared with welding, grooving or threading tube.

Steve added: “We are very happy with the Viega systems, which have been quick, easy to use and reliable. The installation at Tollgate Gardens has been very straightforward, especially with Megapress which has sped up the process significantly.”
