Polypropylene Joint Filler

Polypropylene is an expansion joint filler product used in
residential, commercial, civil, municipal and industrial
applications. It is easy to handle and extends the service life
of concrete by acting as an insulator for contraction and
expansion joints. It can be used with hot-pour or coldapplied
sealants. Polypropylene prevents three-sided
adhesion and can be used without a bond breaker. It also
has no odor or sticky residue and is resistant to oils, gas,
salts and other chemicals.
