Joint Sealing
Professional sealing of movement, expansion and construction joints to accommodate movement and protect structures against water, moisture and contaminant ingress.
Service overview
Understanding the support available.
Nia Build provides professional joint sealing for concrete structures, floors, façades and other building elements where joints require durable and flexible sealing. We assess the joint type, dimensions, substrate condition, expected movement and exposure before selecting an appropriate sealant system. Our work includes joint preparation, installation of backing material where required, application of primers where specified, sealant installation and finishing. Particular attention is given to correct joint geometry and adhesion so that the installed sealant can perform effectively under its intended service conditions.
