When compared to conventional brick & block construction, the Waffle-Crete precast concrete building system will:

Reduce material & labor costs

Slash construction time

Eliminate the need for skilled labor

Very low life cycle cost (low ongoing maintenance)

The Waffle-Crete Advantage9

At the heart of the Waffle-Crete Building

System

Insulated Waffle-Crete Mold

Insulated Waffle-Crete Curing Cover

Waffle-Crete molds are lightweight and portable

Concrete panels can be cast right on the job site

Panels can be cast one day and erected the next

Unparalleled Construction Speed

The horizontal ribs act like beams

The Strength Is In the Ribs!

04/12/2023Waffle-Crete International, Inc.

14

Up to 60% of the concrete and steel is eliminated between the ribs.

60% Less Material Without Loss of Strength

First Waffle-Crete Project in the Marshall Islands

Completed Well Ahead of Schedule and Under Budget

Waffle-Crete International, Inc.

PII chose Waffle-Crete

because it makes

concrete construction on

the islands faster and

more affordable.

PII erected its first
