INDIA’S FIRST DEFENSE-GRADE
PORTABLE BUNKER SYSTEM
PORTABLE BUNKER is a modular, rifle-resistant, high-strength concrete structure engineered for rapid deployment and superior protection. Developed in collaboration with the Indian Army (52 Engineer Regiment), this system is a breakthrough in mobile defense infrastructure — Made in India, Designed for the Field.
WHAT IS PORTABLE BUNKER?
Portable Bunker is a patented defense-grade shelter system manufactured by Roschcrete Technologies Pvt. Ltd. It features a 3D interlocking modular design made from M80–M120 grade high-performance concrete, enabling rapid installation without cranes or heavy machinery.
Tested by TBRL and validated in Northern Command field trials, the system provides reliable ballistic protection and unmatched mobility across terrains and scenarios.

Kill house construction
Live-fire training rooms that take the hits and stay quiet
A kill house is a CQB facility your teams shoot inside, day after day. That puts two demands on the building at once: stop the round where it lands, and keep the noise from wrecking the people training. Roschcrete builds the shell and the six systems that line it as one package. Point at a system to find it in the plan.
-
Fixed wall panels
The permanent ballistic skin of the shell, sized to the room and anchored to the structure.
-
Modular walls
Repositionable partitions, so instructors can rebuild the floor plan between serials.
-
Ceiling
A base lining that catches upward strikes, with an acoustic layer above it.
-
Floor panels
Anti-ricochet flooring that absorbs downward rounds instead of throwing them back.
-
Acoustic insulation
Sound treatment worked to a target of 80 dB or lower inside the training space.
-
Glazing
Observation and door glass rated to EN 1063 BR6 and NIJ Level III.
