Waterproof Hardware Designed for Building Envelope Integrity

Eliminate structural failure where it starts: the connection point.

Waterproof hardware plays a critical role in protecting the building envelope—yet most mounting systems and fasteners still rely on sealants, gaskets, or field-applied fixes to manage water intrusion. These methods degrade over time and leave penetrations vulnerable to leaks, corrosion, and structural failure.

At Nill Building Solutions, we engineer mounting and fastening hardware that gives architects, engineers, and builders the ability to properly waterproof penetrations at the attachment point—where failures most often begin.

The NILLWAY® Starts Here

Water damage is what happens when you build the old way.

It’s not just better—it’s the standard with NILLWAY®

ICC-ES Evaluated for Superior Performance

It’s easy for a company to say their products are high-quality. It’s harder to prove it. That’s why NILLWAY® puts every attachment solution through independent third-party evaluation by the International Code Council Evaluation Services — ICC-ES.

ICC-ES testing doesn’t go easy. Products are evaluated for structural load capacity, exposure to extreme weather, and long-term durability — including full compliance with Miami-Dade County standards, one of the toughest building code requirements in the country.

What that means for you: when you spec NILLWAY® waterproof structural fasteners, you know exactly what you’re getting. No surprises. No liability risk. Just products that perform the way they’re supposed to — every single time.

The Fastener for the Fastener®

Engineered for Every Application. Built to Outperform.

Whether you’re building a glass railing mounts on a rooftop deck or running plumbing and electrical fasteners through a waterproofed wall, NILLWAY® has an attachment solution designed specifically for that job. These aren’t adapted, off-the-shelf products — they’re purpose-built for the challenge in front of you.

From windows and doors to concrete structures, from solar panel installations to stucco and façade systems — if a fastener is going through a waterproofing membrane, NILLWAY® has done the engineering work already.

 Trustindex verifies that the original source of the review is Google. Nill Building Solutions is a game changer!
I had a second story roof deck with 30+ posts that the architect wanted to be installed through the rubber roofing.  30+ possible leaks!!
The Nill posts were a life saver. No penetration and no leaks.
Thank you Thomas and thank you Nill Building Solutions for a great product!

 Trustindex verifies that the original source of the review is Google. When I am negotiating connections between and through the varied materials at the cocktail party of personalities otherwise known as building enclosure assemblies, I can always turn to Nill Building Solutions for solutions to address the requirements of all of the component parties, while meeting or typically exceeding the project goals.

 Trustindex verifies that the original source of the review is Google. I recently worked on a large project with multiple roof penetrations for electrical runs, Thomas provided us with mounting solutions that were critical in maintaining the building’s waterproofing. Knowledgeable, practical, and easy to work with—highly recommend.
