Manufacturing process
Production procedures follow a multiphase process in an off-site facility. First, production plans are created by CAD designers from architectural blueprints. Forms are prepared with steel rebar and styrofoam. The concrete mix is created at 5,000 psi and bonds directly to the foam insulation. The panels are then finished with the application of a vibrating screen to assist flow and fill potential voids, while creating greater surface consistency.

Installation
Completed wall panels are transported to the job site via special carrier trucks and lowered into place by cranes. Crews install and permanently secure the foundation on a bed of crushed stone. Panels are joined together by stainless-steel bolts and sealed at joints with urethane sealant. The company claims that installations typically take less than one day and can be completed in adverse weather.
