Tufflon-JF90 (Joint Filler) 

The latest joint-filling technology, using rapid-set, high-strength, pure polyurea to protect concrete floor expansion joints from damage is now here.

Designed by Australia's leading industrial chemists and made under ISO9001, Tufflon-JF90 Joint Filler offers asset owners a solution to the problem of concrete floor slabs having the edges of construction and expansion joints damaged, broken and chipped. It does this by combining extremely high, load-bearing physical properties with a permanent elasticity of 430% and a vice-like grip to the vertical concrete surface of the joint. This allows Tufflon-JF90 to not only support the edges of the joint but to also stretch and contract in order to accommodate the daily cyclical movement of the slabs.

Tufflon-JF90 (Joint Filler) 

This highly-modified, pure polyurea Tufflon-JF90, is in a class of its own by combining these three amazing properties in the one product.


Failure to properly seal or fill concrete floor expansion joints, allows water, debris and harsh contaminants to fill these critical engineered structures, which can cause premature wear and tear to the concrete. When installed by experienced tradesmen, Tufflon-JF90 filled joints can be returned to service in just over 60 minutes. Fast to install, fast to cure, it forms a permanently elastomeric and tough load-bearing joint with high physical properties that cannot be matched by standard single component polyurethane joint sealant. When time is money, there is no other system that can match the speed of installation and quick return to service of Tufflon-JF90 polyurea joint filler.

Applications and Benefits of Tufflon-JF90

Tufflon-JF90 is versatile in its applications and suitable for joint filling and stress crack filling in concrete floors. It excels in environments that bear very heavy loads, making it a preferred choice for warehouses, manufacturing plants, and other high-traffic areas.

Preventing Premature Wear with Effective Joint Filling

Neglecting to properly seal concrete floor expansion joints can lead to water ingress, debris accumulation, and exposure to harsh contaminants. These issues can cause premature wear and tear on concrete. Tufflon-JF90, when installed by skilled professionals, forms a permanently elastomeric and tough load-bearing joint. This effectively prevents the deterioration of concrete, ensuring the longevity of the floor.
