Supporting Resilient, Sustainable Family Homes

In Gig Harbor, Washington, a collaboration between Heidelberg Materials North America, Tacoma/Pierce County Habitat for Humanity, and their partners has showcased an innovative approach to construction: Insulated Concrete Forms (ICF) using concrete produced with EvoBuild® Low Carbon Concrete and Recycled Concrete Aggregate (RCA). This project was supplied by Corliss Resources LLC, a Heidelberg Materials company which has started its rebranding to Heidelberg Materials this week. 

By leveraging Heidelberg Materials' Revolve™ RCA product, the second and third homes in the development have succeeded in substituting over 90% of virgin coarse aggregate with recycled material. This advancement marks a significant stride within the concrete industry toward sustainable, circular practices, while concurrently delivering secure, economical, and resilient housing options for families and communities.

The advantages of ICF construction are multifaceted, encompassing fire resistance, energy efficiency and sustainability. Notably, the system also excels in noise reduction, owing to the acoustical insulation capabilities of the EPS panels and the substantial concrete walls. Situated adjacent to Hwy 16, mitigating noise pollution emerged as a critical consideration, making the adoption of ICF construction methodologies a prudent departure from conventional building practices.

Clark Construction, hailing from Bainbridge Island, assumed the role of general contractor for all three homes, bringing with them extensive proficiency in ICF construction techniques. A consortium of members from the National Ready Mix Concrete Association (NRMCA) and partners associated with the Build with Strength coalition have generously contributed discounted or donated materials for this endeavor. Noteworthy contributors include the Washington Aggregates & Concrete Association, Quad-Lock, Heidelberg Materials, Airfoam Industries, Brundage Bone, Solid Carbon, American Concrete Pumpers Association and Insulating Concrete Forms Manufacturers Association.

This project forms part of a broader collaboration between Build with Strength and Habitat for Humanity International, aiming to erect at least 50 sustainable concrete homes across 50 states within a span of five years. Presently, according to the NRMCA, the partnership has propelled the construction of 76 homes in various phases across 33 states in less than 2.5 years, underscoring its commitment to sustainable, resilient housing solutions.

Heidelberg Materials has been involved in several of the projects around the country championing sustainability with optimizing concrete mixtures for lower carbon with EvoBuild®, EcoCemPLC™ and Revolve™ recycled aggregates.
