About Us


ProtectiFlex, LLC (ProtectiFlex) is a small business based in New York that was established by the primary engineers of Stone Security Engineering and the original developers of the patented material in masonry block product, Enviromate, Ltd.

Protectiflex is a ‘one-stop-shop’ providing innovative and cost-effective concrete-like material solutions for clients who need to meet security and/or industrial safety design requirements in the following areas:

  • blast

  • ballistic

  • forced entry

  • impact

  • weapon effects

  • fire

  • seismic

Our Expertise


ProtectiFlex designs are created by industry leading engineers from Stone Security Engineering and our product developer partners who have expertise in protective design consulting, extreme loading testing (blast, ballistics, forced entry, etc), research and development, conventional and innovative concrete construction and installations.

This expertise has resulted in innovative designs, product lines and construction techniques that meet and exceed security and safety requirements at a competitive price, bringing value to your critical projects.

ProtectiFlex is part of the StoneSmart Solutions product development efforts dedicated to developing innovative products and services for the security industry.


Protectiflex material


ProtectiFlex offers protection against blast, ballistic, forced entry, impact, weapon effects, fire and seismic loads and can be used to mitigate risk against accidents, natural disasters and direct attacks. ProtectiFlex is suitable for new or retrofit construction and can be developed for various applications including façade systems, component shielding, tunnels, anti-ram systems, fully-integrated modular systems and more.

ProtectiFlex is a proprietary technology combining recycled non-biodegradable material, composite fibers and/or rebar in a cement matrix. It can be manufactured in a batching plant using conventional equipment and poured in place or formed into self-stacking blocks, panels or barriers. This adaptability provides a cost effective solution in a wide range of architectural finishes resembling traditional concrete.

ProtectiFlex has undergone rigorous testing and has earned several ballistic, blast and fire accreditations:

·        Blast Testing conducted simulating car bomb explosions in accordance with blast testing methodologies and performance guidelines referenced in

         DoD, GSA, ISO, CPNI and UK Home Office Standards and Reports.

·        Blast Testing conducted simulating hand-carried bomb explosions at close-range.

·        Weapon Effects Testing from various projectiles.

·        NIJ-STD-0108.01 and UL 752 Ballistic Testing and Accreditation to all levels for various thicknesses and mix designs.

·        Ballistic Testing also carried out in accordance with methodologies and guidelines provided in the BS EN1063:2000 and BS EN1522 Standards.

·        2 Hour Fire Testing and Rating in accordance to the BS EN 1364-1 2015 Standard.




Tough – Protection of people and critical assets is at the heart of ProtectiFlex objectives. Its design prevents bullet penetration, reduces spalling and is able to absorb large amounts of energy without diminishing its structural integrity.

One-Solution – ProtectiFlex offers a single material solution for the diverse effects from Blast, Ballistic & Fragmentation, Weapon Effects, Forced Entry, Fire and Seismic loads. In contrast, conventional concrete and masonry material products used for high threat environments are dense, brittle and lack enhanced damping characteristics.

Lightweight – The base material of ProtectiFlex systems is 30% less dense than concrete with enhanced energy absorbing characteristics; Resulting in lighter, thinner structures that are faster to build, cheaper and more usable.

Flexible – Protectiflex is more than 100 times as flexible as concrete and has 20 times the strain capacity of traditional concrete before failure.

Eco-Friendly – ProtectiFlex is created from recycled materials, uses less energy to manufacture, is sustainable and non-biodegradable.

Cost-Effective – ProtectiFlex is designed to utilize existing construction implementation practices in the masonry, cast-in-place and precast concrete industries. Our concrete-like material can be treated like true concrete during manufacturing with no retooling necessary, allowing a wider variety of applications.
