Built With Foam

Built With Foam is proud to be a US Veteran owned business based in Houston, Texas.

As former contractors, we know what you need to make a job successful. Our team has a combined 90+ years of experience in the building trades including tile installation, high-end homes, historic properties, and commercial spaces.

Over our decades in the industry we’ve witnessed the evolution and prevalence of foam products on the jobsite. Not only is custom foam cheaper as a building material, it can cut down on labor, substantially speeds projects, and can remove a lot of the typical hurdles faced daily. We’ve put our experience into designing and manufacturing quality products which can make the lives of our fellow tradesmen and tradeswomen much easier.

Exclusive Products

Our exclusive Tub Arch™, Shower Arch™, Tub Dome™, Shower Dome™, products eliminate the need for complicated, time consuming, and expensive framing along with the usual jobsite “discussions” that inevitably happen.

Wall Shims

Our wall shims are flattering, easy to install, need no special tools, and can be left to set overnight making them ideal for busy contractors or DIY weekend warriors. You can check your flatness without a making a mess, without risk of overdriving screws, and without waiting for setting to finalize waterproofing!

Why EPS...

Built With Foam brings any construction or remodeling vision to life through the power of Expanded Polystyrene (EPS), a rigid, high-density foam plastic that is completely customizable, lightweight, moisture-resistant, durable, easy-to-install, and cost-effective.

EPS is a perfect substrate for bath tile and stone, but it can be used to create furniture and architectural detail for any room of the home or application at a fraction of the cost of traditional wood framing.

I’ve been using the Built with Foam shims for over 6 months now and I can honestly say that I won’t do a shower without them. For me straightening walls has always been a challenge, this system makes the process a lot simpler. I like the fact that when I’m finished I have plumb and square walls to set my tile on. Thanks Paul for designing a great product.

Built With Foam has come through for our company in a big way! We needed a huge pan and fast, Cabot answered our call in the middle of a convention and got us set up same day. It showed up quickly and fit like a glove. Perfect is what I aim for and Built With Foam helped us achieve it flawlessly!

They make it easy as can be, sent in my measurements I was contacted the next day with a few questions just to clarify I was getting exactly what I wanted and was shipped and on my doorstep within a week and fit perfectly. Very satisfied 10/10
