Policord is suitable to support sealants in expansion joints.
Policord polyethylene foam back-up cords have the ability to perform several functions. They enable the correct width to depth ratio of the sealing slot to be maintained and provide a firm backing for the sealant to be tooled.
The use of Policord will also act as a bond breaker at the base of the joint thus preventing three side adhesion and the accompanying additional stress during joint movement.
