Expansion joints allow parts of a building to accommodate movement caused by temperature changes, material expansion, structural movement and settlement. A correctly functioning joint helps reduce uncontrolled cracking and water ingress.
Common warning signs include cracking, splitting, hardening, separation from the joint edges, missing sections and water entering around windows, façade panels or external building joints.
The existing failed sealant is removed, the joint is cleaned and prepared, backing rod or bond-breaking material is installed where required, and a compatible façade sealant is applied using the correct joint profile.
Yes. Rope access is often suitable for sealant and expansion-joint replacement on high-rise façades, allowing technicians to reach difficult areas without installing extensive scaffolding.
Yes. Failed, separated or incorrectly installed sealants can allow water to enter behind façade finishes, around windows and through building joints. The source and extent of the defect should be assessed before replacement work begins.
