Buyer Picks a Date, We Handle the Rest

How It Works

Materials

Browse certified surplus with LEED, Passive House, and ESG impact visible on every listing. Sellers list in minutes with AI-assisted spec sheets, no manual paperwork required.

Storage

When a seller's availability and a buyer's delivery date don't line up, ReMat coordinates interim storage through a network of warehouses and private space, invisibly and at no extra step for either side.

Hauling

Vetted logistics partners handle every pickup, transfer, and delivery. Each handoff is photo-documented, so liability and condition are never in question.

We built the ReMat™ platform to handle not just the transaction, but the storage, the pickup, the delivery, and the documentation that lets every material count toward a project’s LEED, Passive House, or ESG targets.

Numbers speak volumes

Up to 30% of materials delivered to a construction site end up as waste

600M tons

Of construction and demolition waste generated in North America in 2023

Source: CMAA – Turning Construction Waste Into Resources

The construction industry creates 30-40% of the world's solid waste, yet most companies treat this as a disposal problem rather than a revenue opportunity. McKinsey & Company's 2023 report projects that recycling and reusing construction materials alone will generate €80 billion in annual value by 2050. This growth is driven not by environmental regulation, but by rising landfill costs, carbon pricing, and infrastructure spending that requires ESG compliance. The companies capturing this value aren't waiting until 2050. They're tracking waste today, converting it to certifications, and using these credentials to win the federal contracts and height permits their competition can't access. The question isn't whether construction waste has value. The question is whether your company will capture that value or continue paying to throw it away.

Turn every ton into progress.

Build tomorrow's infrastructure with today's materials. Tracked, certified, and impossible to ignore.

Real Impact in Numbers

We Saw Where the System Breaks

Our Story

A contractor finishes a project with surplus materials that have nowhere to go. Another project down the road is buying the exact same materials brand new. The only thing standing between them is timing.

We saw this pattern through years of working in real estate finance and construction management across Boston and New York. The market for surplus construction material existed in theory. The infrastructure to make it work did not. We built ReMat to close that gap. Every transaction gives surplus material a paper trail and a second project.
