We provide everything you need for your next project.

RST is a full service ICF (Insulated Concrete Form) construction developer with offices in Mexico, Uruguay, Peru and United States specializing in modern residential, cultural, and commercial architecture.

We work with our clients on designing their structure from concept through completion. From initial planning and defining the scope of work, we remain closely involved in the project through construction to Final Completion.

Building is an extensive process. With the RSTMEX system, you can rely on our speed, low cost, durability, and ease to build. We can reduce construction times by  at least 50%.

The RSTMEX Construction System

The RSTMEX construction system is based on patented ICF (Insulated Concrete Form) technology. This technology reinforces concrete by encapsulating it in non-toxic expanded polystyrene pearls molded in the form of a  “Lego” block. These blocks are fire resistant, mold resistant, they have thermal and acoustic insulation properties and much, much more.

ICF Buildings Can Stand Up to the Toughest Disasters.

It's time to build disaster-proof homes before storms strike, not afterward. ICF´s solid foam exterior and concrete core will provide your family with the protection they need. Our system provides protection from winds as high as 250 mph. RSTMEX structures have endured an 8.3 richter scale earthquake without taking any damage. The RSTMEX system is fire resistant and it does not provide any food or moisture for mold to grow.

Make Your Vision Into a Reality.

Work with our experienced team and create a detail driven structure that will last for generations. Choose from our wide array of products, finishes and services that best suit your project needs.


Versatile System.

From pools and water treatment plants to residential housing and multi story buildings, we love taking on challenging projects and seeing them through to the end. We strive to create architecture that is simple, beautiful, and economical of both means and gestures. We see the value in going above and beyond on every project, in every phase, to bring our client’s visions to life.
