The Problem
ASRS repaired vertical cracking in 16 masonry piers using Helibar crack reinforcement and Dryfix pinning ties. Recommended by Helifix, ASRS was approached by BMW, which needed a contractor to design a specification and carry out the installation to restore the structural integrity of the 16 masonry piers that had experienced vertical cracking due to thermal expansion. The work was conducted over weekends to ensure that the plant could operate normally without disruption.
The Solution
On completion of our survey at the plant ASRS proposed a design for the necessary remedial works required. The specification was to install 322 single bands of Helibar crack reinforcing horizontally across the cracks and to reconnect the masonry piers back to the main structure thus offering substantial resistance to further cracking.
ASRS completed the works within the time scale allowing the plant to operate without any disruption to the day to day running of the plant.
Completed Project
Once all Helifix crack stitches and Dryfix pinning ties had been installed, general repairs were carried out and existing cracks were raked out and injected with thixotropic cementitious grout. All disturbed mortar was made good and the cracked bricks were tinted to match near as practicable.
