Repointing lime mortar
Repointing lime mortar is a process of renewing the mortar joints between bricks, blocks, or stones in a building, typically to restore their structural integrity and aesthetic appearance. Lime mortar repointing involves removing the old, deteriorated mortar and replacing it with a new mixture of lime putty and sand. This is done to address issues such as water damage, crumbling, or cracking, and to ensure the structure remains safe and durable for years to come. The process typically involves cleaning the joints, removing old mortar, mixing and applying the new lime mortar, and tooling it to achieve a smooth finish.
Brick poiting
Brick pointing is a crucial aspect of masonry construction, involving the process of filling the gaps between bricks with mortar to create a strong and durable bond. It requires precision and attention to detail, as the joint must be filled correctly to ensure the structure's stability and weather resistance. A well-pointed joint should be smooth, consistent, and slightly concave, allowing for easy cleaning and reducing the risk of water infiltration. Skilled bricklayers use specialized tools, such as trowels and pointing tamps, to apply and shape the mortar, ensuring a professional-looking finish that will last for years to come.
Pebbledash removal
Pebbledash removal is a popular exterior renovation project that involves removing the existing pebbledash coating from a building's exterior walls and replacing it with a new finish, such as render or cladding. The process typically starts with preparing the surface by cleaning and repairing any damaged areas, followed by applying a primer to ensure a strong bond between the old and new coatings. Next, the pebbledash is carefully removed using hand tools or mechanical scrapers, taking care not to damage the underlying substrate. Once removed, the surface is then cleaned and prepared for the new coating application.
External wall isolation
External wall insulation (EWI) is a technique used to improve the energy efficiency and thermal performance of buildings by insulating the exterior of the building envelope. It involves applying insulation materials, such as foam board, fiberglass, or spray foam, to the exterior walls of a building, typically to a depth of 50-100 mm (2-4 inches). EWI can be installed over existing walls or as part of a new build, and can be finished with various exterior cladding options, such as render, brick slips, or rainscreen systems. The benefits of EWI include improved thermal insulation, reduced heat loss, and a more consistent internal temperature, as well as increased building durability and reduced maintenance requirements.
