Lugar da Muralha de Londres
London Wall Place is large a double tower office development in London built close to the Roman City Wall historical monument.
For this project, Dextra offered contractor Byrne Bros and main consultant WSP a technical solution for the fast installation of precast wall panels.
The concept was to install Groutec couplers in each panel reinforcement, at the bottom of the vertical bars previously prepared with Rolltec thread system, available in the UK through our distributor network.
After bracing the precast panel in its final position, non-shrink grout is injected into the cavity of the coupler, in order to create the rebar connection. Groutec is not reliant on a specific type of grout. Rather, several different brands of grout can be used, facilitating local scouring and helping to keep costs low. The bracing around the panel is then removed after the grout has achieve a prescribed strength.
After straightening and bracing of the precast panel, non-shrink grout is inserted into the cavity by injection. Dextra does not supply grout as Groutec is by design compatible with several brands that can be sourced locally, generating savings and easing project management.After injection, the bracing around the precast panel may then be removed after only 3 days.
The use of Groutec for precast panel is a time-saving and economical way to quickly take advantage of the precast technology. For similar application video, please check The Plum Central Station project page.
