Wall coupling simplifies through-wall
connections
The new Viking Johnson wall coupling turns the complicated process of passing pipes through the concrete walls of wastewater treatment works into a single operation
The new Viking Johnson wall coupling turns the complicated process of passing pipes through the concrete walls of wastewater treatment works into a single operation The coupling is installed in a concrete wall by holding it rigidly between the shutters before pouring concrete to the wall

Viking Johnson coupling slashes time and effort
The new AquaFast couplings and flange adaptors for polyethylene and PVC pipes from Viking Johnson make the installation of pipe joints simpler and quicker than ever
This eliminates either the normal two-stage procedure of leaving a "box-out" in a wall, whereby the puddle pipe can be cast in at a later date; or the expensive cutting and patching of formwork to cast the puddle-pipe in at the initial pour.
Use of wall couplings over the traditional methods not only substantially reduces the total installed cost of puddle pipes to the civil contractor, but also ensures leak tight bonds between concrete and cast in pipes - an essential attribute of water-retaining structures.
The Viking Johnson range of wall couplings offer several end configurations, including coupling, flanged, plain end and man entry, thus offering the civil and mechanical contractor full flexibility in the pipework design.
In addition, the use of a coupling end on the outside wall face acts as the first flexible coupling to the pipeline entering a structure, thereby reducing the number of Viking Johnson couplings in the standard 'rocker pipe ' configuration required to accommodate ground settlement.
Taken together, all these benefits offer significant savings on installed cost and programme time, especially where a large number of through-the-wall joints are involved, for example in a gravity treatment works. Request a free brochure from Viking Johnson ...
