Permacell™ Weather Resistant Solid Aggregate Drainage Material

Water freely draining through a Permacell™ brick.

Goodson & Associates has developed and patented a method for creating a strong, permeable cellular concrete material composed of open-graded aggregate (ranging from about .25" to 2") and a cementitious compound. This material can be used in projects where drainage along with stability are required. Our patented method correctly injects air to prevent aggregate "pop out" due to freeze/thaw cycles. This problem was previously believed to be inevitable in material of this kind. Some typical applications include the following:

Drainage structures
Permeable Road Base
Scour Protection
Retaining Walls/Retaining Wall Backing
Patios
Foundation Drains
Pipeline Beds
Greenhouse Flooring/Flatwork
