Sikaflex® Construction Purform

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.
