Core-Fill 500 can be retrofitted into any existing block structure. Core-fill 500 fills the cavities completely and seals all air penetrations.  It also helps to keep rodents and insects out, and helps maintain a stable environment inside the structure.


We retrofitted foam into all of the Casitas at the Scottsdale Camelback Resort  

This is a typical Arizona Slump Block home that we are retrofitting with Foam.  It’s an easy one-day job that provides a lifetime of savings.
