No state license for this trade. New Hampshire doesn't license or register waterproofing / foundationbusinesses, so there's no state registry to check. That's true of every waterproofing / foundation business in the state, not a mark against this one. Insurance is self-reported.

Highlights
- Established commercial track record — 54 tracked projects on Procore since 2023
- Would not recommend — one Google review gave no reason
- Mostly commercial focus — residential ICF work is only occasional
Key Industries LLC is a commercial concrete contractor based in New Ipswich, NH, co-founded by Joshua Salmonson and Matthew Salmonson, who describe the business as veteran-owned. Its focus is Insulated Concrete Form (ICF) construction, concrete tilt-up work and foundations for commercial and industrial projects across New England, with occasional residential ICF jobs. The company tracks 54 projects on Procore Construction Network since joining the platform in 2023, averaging roughly $9 million per project — evidence of an established commercial book of work, though that figure measures project scale, not customer satisfaction. Customer feedback is very thin: the only rating on file is a single 1★ Google review from February 2026, in which the customer wrote only that they 'would not recommend' the company, without giving a reason. Given the company's primarily commercial focus, a homeowner considering them for a residential ICF foundation should confirm they're taking on residential work and ask directly about that one negative review before booking.
