About M-Tech

Built on Three Decades of Solving the Impossible

M-TECH was founded in 1992 by Bundit Klinwitthaya, a pioneer in applying robotic technologies to structural demolition in Thailand.

For over 30 years, we have delivered demolition, concrete cutting, drilling, and structural modification solutions for complex projects across Thailand and overseas—from confined spaces and occupied buildings to post-tension and underwater structures.

Real-world project experience has shaped our engineering expertise, driving the development of proprietary tools, techniques, and specialized machinery. Every machine is designed, built, and operated by M-TECH's own engineering team, ensuring each project's unique challenges are met efficiently.

Today, we continue to deliver safe, precise, and low-impact demolition solutions, setting new standards through engineering excellence and continuous innovation.
