Summary
🏗 Preparation & Assessment: Roger inspects the chimney stack and explains the damage. The cement pointing had failed due to frost, leading to loose mortar and bricks.
🔨 Chasing Out Mortar: The old mortar is removed using a grinder and chisel, ensuring a clean depth of 20-25mm for reporting.
🏠 Lime vs. Cement: The issue with cement pointing is that it traps moisture, damaging the structure. Lime mortar (NHL 5) is selected for flexibility and durability.
🧱 Brick Replacement & Color Matching: New imperial-size bricks are chosen to match the existing structure for an aesthetically seamless repair.
🏺 Pot Reinstallation & Flaunching: The old flaunching is removed, and the pots are checked for cracks. They are reset securely using slates for added support.
🔗 Structural Tying: To correct the chimney’s outward lean (15mm deviation), helical ties are installed into the brickwork to reinforce stability.
🏗 Resin Bonding: The helical ties are embedded in resin and concealed under the pointing to blend with the original chimney.
🌧 Final Coating: A storm dry coating is applied to keep moisture out while allowing the chimney to breathe, preserving its longevity.
Insights Based on Numbers
📏 20-25mm Depth: The mortar was carefully chiselled out to this depth, ensuring a solid repointing foundation.
🌡 15mm Lean: The chimney had shifted over time, necessitating structural reinforcement.
🔩 Every Fourth Course: Helical ties were installed at every fourth brick course to secure the structure effectively.
