Walings are designed to transmit all loads from the soil through the retaining wall to the steel tie bars and to align and brace the wall in its position. In many applications, a steel waler or reinforced concrete beam is used to transfer retained loads evenly between tie rod connection points.
A steel waling system provides greater flexibility in positioning of the tie rod system enabling optimum design and on-site installation.
Waller beams are fabricated using either back to back channel sections or structural beam sections, depending on the tie rod loads. Spacer plates between the sections are sized and fabricated to allow the tie rod to pass through the waler with sufficient space for rotation of the tie rod where articulation is part of the design.
Walers are used to hold form work panels / shuttering plates / shuttering ply. They act as primary beams to use with Tie Rod to hold the form work.
