At every joint, different building elements, materials, and trades come together. Proper joint sealing ensures these connections can move as needed while remaining watertight, airtight, and durable. Sika offers professional joint sealants and systems for façade, interior, expansion, and civil engineering joints — protecting your building where it is most vulnerable to leakage.
Why Joint Sealing is Important
The building blocks of your construction - like the concrete slab, the glass facade element, the roofing membrane, the metal cover - generally do not let water, moisture or air enter the building or structure. It is at the joints where a building is weakest to leakage. Only correctly specified and professionally applied high quality joint sealants will manage to keep your building or structure sustainably tight during its entire lifespan.

Sikaflex® Purform®
Polyurethane Technology with Ultra-Low Monomer Content
Purform® is a revolutionary new polyurethane technology, developed by Sika. It is a more sustainable and environmentally friendly alternative to traditional polyurethane based products, thanks to its ultra-low VOC and low monomer content.
Using Purform® in place of traditional polyurethane within two of our key products, Sikaflex®-11 FC and Sikaflex® PRO-3, future-proofs our products.
Purform® technology meets the latest new EU REACH regulations which are coming into force in 2023. Like many polyurethane-based sealants and adhesives, Sika products using Purform also benefit from many attributes including:
- Better tooling and application - particularly in colder weather - than traditional polyurethanes.
- Improved performance in damp surfaces.Resistant to many chemicals and maintains a high level of performance, even in harsh environments.
- Creep resistance.
- Bubble free curing.
