Hycrete Inc., a green building materials company, has completed its 100th project, the New Jersey-based company announced.

Hycrete produces an environmentally friendly admixture that integrally waterproofs concrete used in commercial construction. Developed over the span of nearly four decades, the Hycrete technology was first used in 2003 for a pre-cast barrier project.

The company began pouring its 100th project, a Seattle parking garage, earlier this fall. In 100 projects, the company estimated it has treated more than 5 million square feet of concrete.

The Hycrete Element admixture is certified Cradle-to-Cradle by McDonough Braungart Design Chemistry, LLC (MBDC) and part of the larger Hycrete IntegraTek Waterproofing System. The system combines service with the admixture to waterproof entire concrete structures, and eliminates the need for external membranes typically used to waterproof concrete. This approach also makes the concrete more-easily recyclable following demolition, and can eliminate thousands of pounds of Volatile Organic Compounds (VOCs), CO2, and non-renewable content.
