Jointfill N1

Jointfill N1 is a polymer modified, bituminous, hot applied joint sealant compound. It is designed to be tough, flexible and have good extension properties over a wide range of ambient temperatures. Jointfill N1 is suitable for joints between concrete and bituminous surfacing preventing entry of water and other materials. It has excellent recovery properties and low temperature flexibility.

Jointfill N1 is not recommended for overbanding due to its lack of skid resistance. Jointgrip OB is recommended for overbanding due to its superior skid resistance properties.

Damaged joints must be repaired using an epoxy mortar approved by Colas. If necessary joints should also be treated by grit blasting. Joints and cracks should always be thoroughly cleaned and dried with a hot compressed air lance in order to remove all moisture and dirt. This process should be carried out immediately prior to the application of Jointfill N1.

 

Concrete joints should be primed with CP Primer before applying Jointfill N1.

Jointfill N1 should be heated indirectly and agitated in a purpose-built sealant preheater unit with thermostatic control. Ensuring that the temperature does not exceed 190°C. The heater unit should be air-jacketed or oil-jacketed. The materials should then be pumped in to the joint, or poured at temperatures between 170-190°C using a melter pourer or bucket with a 'V' lip, with the minimum loss of temperature. Joints should be sealed to a level of at least 3mm below the surface.
