FlexProof 106 – High-Performance Flexible Joint Waterproofing
FlexProof 106 is a highly advanced, single-component liquid waterproofing material that forms an elastomeric polymer membrane. It is rainproof within minutes and effectively handles severe building movements and deformations, making it ideal for construction joints.
Product Variants
-
FlexProof 106 X1 – Thixotropic paste for surface sealing over static joints.
-
FlexProof 106 NV – Low-viscosity variant for movement joints in precast concrete.
-
FlexProof 106 Primer (Product Code: 916) – Enhances adhesion to porous surfaces.
-
FoamStop Backing Rods (FS1-FS8) – Used for movement joints.
Key Benefits
✔ No mixing required – Ready-to-use straight from packaging.
✔ Quick application – Can be applied in sub-zero temperatures and on damp surfaces.
✔ Primer-free – Saves additional material and labor costs.
✔ 100% waterproof yet breathable – Allows vapour diffusion while preventing water penetration.
✔ Highly flexible – Resistant to movement and cracks in the substrate.
✔ Temperature resistance – Remains stable between -40ºC and 90ºC.
✔ Strong adhesion – Bonds securely to concrete and other substrates.
✔ Excellent chemical resistance – Withstands the high alkalinity of concrete.
Ideal Applications
🔹 FlexProof 106 X1 – For static construction joints in poured concrete structures.
🔹 FlexProof 106 NV – For non-static movement joints in precast concrete elements.

* EN ISO 11431:2002 specifies a method for the determination of the adhesion/cohesion properties of sealants after cyclic exposure to heat and artificial light followed by a period of exposure to water at a defined temperature. The 10-year figure is an extrapolation of the results of these tests. The product may weather to with a slight yellow tint, but the product itself will not be
affected.
