1. Applicators' Favorite for Over 40 Years
Sealing joints on the construction sites all over the world since over 40 years.
Sikaflex® Construction is sold globally in over 100 countries for projects of every size. The new Sikaflex® Construction Purform® offers an exceptional balance of properties that ensure reliable and durable sealing while minimizing exposure for the applicator.
2. Reliable and Durable
Polyurethane offers the best balance of properties for sealing and bonding in construction.
A reliable and durable sealed joint is the sum of such mechanical properties combined with best hydrolysis resistance and thus making it the first choice of professional applicators where durability counts.
3. Purform® Polyurethane Technology
Purform® is Sika’s new future-proof polyurethane platform that allows us to make better products with the lowest exposure for the applicators.
Purform® Polyurethane Technology builds on the strengths of polyurethane, empowering our engineers to craft Sikaflex® sealants and adhesives that strike the right balance of properties, all while maintaining low monomer diisocyanate contents for optimal overall performance.
4. Wide Range of Applications
Sikaflex® Construction Purform® can be used across a wide variety of construction application areas, both interior and exterior.

1. Facade movement joints
Buildings are permanently in movement, mainly due to temperature differences from day-night or seasonal. To avoid uncontrolled cracking movement joints are designed all over the building. These joints need to be sealed with an elastic sealant that can compensate for the movement and durably avoid water ingress. Otherwise, water will enter and decay the building substance.
Make it right, make it tight.
2. Window connection/ perimeter joints
For a tight connection between the rough brick-cement, wood or concrete construction and window frame. All these materials have very different thermal expansion properties which can be bridged by the elastic sealant. A non-airtight and leaking connection to the building leads to energy loss and moist areas around the window on which mold can grow, for example.
Make it right, make it tight.
3. Concrete construction Joints
Concrete slabs have limited dimensions due to shrinking and cracking issues. Therefore, there are always joints that need to be waterproofed between concrete slabs. The joint width also varies due to the thermal movement of the concrete slabs.
Therefore, only an elastic and hydrolysis resistant sealant can durably waterproof such joints. As Sikaflex® sealants are available in several colors, the joints naturally integrate into the structure.
4. Interior sealing, crack-free
Interior connection joints can show considerable movement during construction (drying) or seasons (dry air in winter from heating allows wood to shrink, humid air in summer allows wood to swell).
5. Connection joints
It’s at the joints where your building is most vulnerable to water ingress! Only elastic sealants such as Sikaflex® Construction Purform® can compensate for movement and vibration, ongoing shrinking, and imperfections and roughness between the building blocks.
