SPIE has agreed to acquire the Czech-based BLOCK Group, a specialist in cleanroom design, engineering and construction.
The move is aimed at strengthening its position in high-specification industrial and healthcare environments across Central Europe.
“Becoming part of a strong international organisation will allow us to accelerate our development, expand our offering and deliver even more ambitious projects to our clients,” said Lukáš Vachala, CEO of BLOCK Group.
Announced last week, the deal will see SPIE integrate a business known for delivering turnkey cleanroom solutions spanning design, engineering, installation, validation and ongoing services.
BLOCK also brings capabilities in process automation and high-voltage systems, supporting clients in pharmaceuticals, biotechnology, healthcare, microelectronics and optics.
Founded in 1991, BLOCK generated approximately €50m in revenue in FY2025 and employs around 160 staff.
The transaction is expected to complete in Q2 2026, subject to customary regulatory approvals.
A subsidiary of BLOCK Group
Last December, a subsidiary of BLOCK Group, BLOCK Technology was rebranded as Timotec Reinraumtechnik and expanded its capabilities from cleanroom solutions to prototype monitoring systems for gene therapy isolators.
The rebrand of TIMOTEC Reinraumtechnik as a German entity of BLOCK Group’s former operations follows earlier strategic changes and ownership restructuring prior to this deal.
Cleanroom Technology reached out to representatives at Timotec Rinraumtechnik to understand how SPIE’s current acquisition of BLOCK Group sits outside of the TIMOTEC acquisition.
The company responded saying that TIMOTEC has already been positioned independently in the German market through different investment activity, and sits outside the scope of SPIE’s current acquisition of the Czech-based BLOCK Group.
