Brickwork Services Project
Tower Mill – Manchester brickwork services project. The 45 meter high circular brick chimney was originally linked to Lancashire coal fired boilers, yet due to the introduction of gas generating boiler systems, the chimney became obsolete. This drastic changeover eliminated all sources of heat, allowing total saturation of the brickwork that resulted in excessive deterioration both internally and externally.
The main area of concern was the condition of the brickwork in the top 15mtrs, where the jointing mortar had deteriorated receding back to a depth of 30mm. The brickwork was loose, fractured and a high proportion of the brick face had eroded. The remainder of the chimney contained numerous deep fractures, diminishing the overall structural stability.
We submitted our findings and recommendations for repair to the client and the Local Metropolitan Borough Conservation Controlling Officer, who sanctioned an immediate repair program.
To provide a safe system of work, and provide protection for the clients’ personnel, scaffolding was erected to the top 17mtrs of the chimney.
Approximately 570NO defective bricks were removed and replaced with the exact dimension and colour match, embedded with a putty, lime, cement and sand mortar to be in keeping with the original construction design.
The top 13mtrs of brickwork and deep fractures were cleaned back and re-pointed with the putty, lime, sand and cement mortar. Mild steel retaining bands were fabricated and fitted to the lower section of the barrel, and a termination mild steel cap was fitted.
Throughout the project periodical inspections were carried out by the Metropolitan Borough Controlling Officers who, upon completion, gave acceptance with a professional Grade A accreditation.
