THERMOLASTIC Joint Filler for expansion joints is a permanently flexible, polysulfide rubber-base material for filling vertical joints in concrete. (Horizontal Joint Filler also available; sold separately.) THERMOLASTIC will pay for its installation many times due to the water saved and the long life expectancy.

Leaky expansion and construction joints result in greatly increased water consumption. THERMOLASTIC, after the addition of the catalyst, cures to a resilient solid rubber material within 48 hours after mixing. It will stretch to double its original dimensions without failing and will return to its original dimensions when the stress is relieved.

Being approximately 100% solids, it will completely fill an opening without shrinking, cracking, or losing adhesion, provided it is properly installed by an experienced person. It has remarkable adhesion on all primed concrete surfaces. It offers a permanent attachment as these surfaces expand and contract. Its tensile strength is over 100 PSI. It also has excellent weathering qualities remaining flexible and in its original condition for 20 years or more in sunlight and water.
