Tuck pointing involves the removal of damaged or deteriorated mortar from between bricks or stones, followed by the application of new mortar in a specific pattern. This technique is distinct because it aims not only to repair but also to enhance the aesthetic quality of the masonry work.
Many buildings requiring tuck pointing are historic or listed structures. This means the work must adhere to preservation standards, which often dictate the exact materials and methods used. This adds another layer of complexity to the job.
Why is Tuck Pointing Necessary
Structural Integrity
Over time, mortar joints can erode due to weather exposure, leading to weakened structural support. Tuck pointing restores these joints, preventing further damage or water infiltration which could lead to more severe issues like cracks or collapses
Aesthetic Enhancement
Tuck pointing can make old or uneven brickwork look new again. It’s particularly useful in historic structures where maintaining the original appearance is crucial. The technique involves creating an illusion of finely jointed brickwork where it might not exist, enhancing the visual appeal.
The Process
Inspection: Before starting, we will assesses the condition of the mortar joints to determine the extent of repair needed.
Grinding Out Old Mortar: Using a grinder or Arbortech the old / damaged mortar is removed to a depth typically around 25mm or deeper if necessary. This step is crucial for ensuring a good bond with the new mortar.
Preparation of Mortar: The new mortar should match the old in color and composition as closely as possible, especially for historic preservation. The mix often includes lime for flexibility and compatibility with old bricks and pigments to attain the correct colour.
