Joint Sealing

At the joint, the different building elements, materials and trades meet. A joint occurs where two components meet and may occur within an element of construction or at part of an interface between two elements. Joint sealing facilitates construction, as a number of components made of different materials are used. Joints allow for needed movement of the materials but must remain water, air, heat, cold and vapor tight. Avoid making mistakes where your building is most vulnerable to leakage – the joint.

• for non-porous substrates like metal and glass, choose Sika’s innovative silicone range.
• for porous substrates like concrete, bricks and masonry, choose Sika’s advanced polyurethane sealants.
• for applications where a wide adhesion range is required like for window installations, the unique silane-modified polymer sealants are most suitable.
• for joints which are too wide for applied sealants or requiring substantial waterproofing, Sika joint tapes, swellable profiles, waterbars and injection hose systems are suggested, depending on a project’s specific needs.
