Manhole Sealing

Total Specialist Maintenance (TSM) is a specialised contractor dedicated to manhole sealing, offering refurbishment and preventative enhancement solutions for both existing and newly constructed concrete and brickwork manhole and chamber structures. We provide our manhole sealing services nationwide across a diverse range of market sectors.

At TSM, we employ a variety of manhole sealing systems, including polyurethane and elastomer gel resin injection, cementitious grouting, hybrid silicate lining systems, and sulfate-resistant cementitious render systems. These techniques create a seamless, chemical-resistant waterproof coating that effectively protects against infiltration.

Our manhole sealing services apply to brick and concrete manholes, wet wells, pumping chambers, and below-ground retaining structures.

Manholes, classified as confined spaces, can suffer from neglect over time and are particularly susceptible to serious infiltration issues in the water, petrochemical, and manufacturing industries. Infiltration can occur regardless of volume or pressure, and if not addressed, it can lead to subsidence, increased demand on final effluent treatment systems, and erosion around the manholes, potentially resulting in localised collapses. At TSM, we are committed to providing effective sealing solutions to prevent these issues and ensure the longevity and safety of your manhole structures.
