Why PermaBASE

The PermaBASE difference

Features & Benefits

Helping you build better

The PermaBASE family of products provide performance and peace of mind with valuable features and applications that save you time and money. We have the size you need and the product quality you expect for all your applications.


PermaBASE Building Products innovated the use of lightweight polystyrene beads within the Portland cement core to provide performance benefits unique to only PermaBASE.


The use of polystyrene aggregate makes PermaBASE significantly lighter and easy to cut. The beads also contribute to the industry's lowest water absorption, preventing the adhering mortar from drying prematurely.


PermaBASE Building Products provides the industry’s best warranties with a lifetime interior warranty and 15-year exterior warranty.
