When you work in a cleanroom lab, precision and control are everything. Every surface, fixture, and process must meet strict standards to protect both people and the critical work carried out inside.

Recently, we were called to help when a significant leak caused major water ingress in a specialist cleanroom lab. Because the lab is airlocked — designed to stop air (and contaminants) moving freely in or out  the water couldn’t escape. Instead, it built up until the lab was flooded to a depth of 10 inches, damaging floors, walls, and threatening the facility’s strict contamination controls.

A challenging environment calls for a specialist approach:

* Strict access protocols: Our team had to follow the same decontamination rules as lab staff — full protective clothing, showering before and after each entry, and strict movement controls in and out of the airlock

* Controlled removal: Damaged materials had to be carefully stripped out and contained to prevent any contamination spreading to other areas. All waste had to be double-bagged and sealed, then placed in a lockable skip, and quarantined for six months in line with site safety procedures.

* Specialist repairs: All works — from repairing the walls to relaying the floors — used cleanroom-approved, hygienic materials designed for easy cleaning and long-term durability.

* Attention to detail: Every joint, seal and surface was finished to the high standards needed for a controlled environment — nothing left to chance.

Over several stages, we removed all flood-damaged wall and floor finishes, made good the substrate, installed new cleanroom panelling, re-laid sealed flooring, and ensured everything met the lab’s tight operational requirements.

Today, the space is spotless, fully compliant, and ready for sensitive work once again — a huge difference from the soaked, damaged state we first stepped into.

Seeing the before and after side by side shows what’s possible when you combine technical know-how with careful planning and an experienced team willing to work to the highest standards, no matter how demanding the conditions.

Well done to everyone involved for working safely and delivering top-quality results under unique challenges 👏
