Rail Waterproofing
Permanent waterproofing for live rail assets
Seal Smart delivers injectable waterproofing engineered for high-risk, restricted-access rail environments. From tunnels and platforms to chambers, shafts and trackside structures, we seal water at the source with minimal disruption to operations.
RISQS approved, every job
Fully RISQS registered with all staff holding PTS and CSCS, and COSS-qualified staff available for possession working.
Turnkey possession delivery
We work alongside a planning and possession company to offer a full turnkey package — from planning and possession booking through to sign-off.
Deep penetration formular
Our formular penetrates cracks, joints and voids that surface coatings cannot reach, sealing the water path itself — permanently.
Fully guaranteed
Every installation is fully guaranteed and documented, with a specification written for the structure in front of us.
