Viking Johnson wall couplings are designed to provide secure, leak-free connections where pipes pass through walls or structures.
\n\n\n\n
They create a reliable seal between the pipeline and the wall opening, preventing the ingress of groundwater and contaminants while maintaining system integrity.

The Problem
\n\n\n\n
The normal procedure for passing pipes through walls is to leave a substantial cut-out in the wall during the original concrete pouring process. Later, the contractor will pass a ‘puddle pipe’ through the cut-out and build an intricate ‘letter-box’ shutter around it. New concrete is then poured into the void to encapsulate the puddle pipe. Not only is this a time-consuming process, but very often the puddle pipe moves with the pour and settles to a less than suitable alignment.

The Viking Johnson Solution
\n\n\n\n
By utilising a Viking Johnson wall coupling which is held rigidly between the shutters, the ‘boxing out’ process is eliminated. This means that pouring the wall is a simplified and is a single step process. It also guarantees that leak paths, which are inevitably set up when new concrete is poured onto old, are eliminated.
Using a standard Type 1 Viking Johnson wall coupling gives a versatile coupling either side of the wall where pipes can either be passed through or inserted into each side.
In addition, the use of a Viking Johnson wall coupling ensures that, on the outside of the structure, the first ‘rocker’ or settlement coupling is built into the shear face of the wall – exactly where it is required.
Consequently, the installed cost can be drastically reduced, particularly where a large number of through the wall joints appear on a building, for instance in a gravity treatment works.

Multiple Connections
\n\n\n\n
The Viking Johnson Wall Coupling is available in nine variations.
Metal components are coated with Rilsan Nylon 11 which is WRAS approved for use with potable water and offers a long term protection to corrosion, impact and abrasion to ensures continued reliable performance.
Using a standard Type 1 Viking Johnson wall coupling gives a flexible coupling either side of the wall where pipes can either be passed through or inserted into \u2028each side. This allows for slight misalignment or \u2028angular deflection on each side of the wall.
Purpose-designed seals for pipes passing through walls, chambers and structures, helping maintain a watertight connection and prevent leakage.
