Home / Manhole renovation
Manhole renovation specialist
We restore degraded manholes to a watertight, strong structure that lasts for decades again. On site, without excavation.
Why renovate manholes?
Wastewater and the gases it produces attack concrete and masonry. This causes leaks, loose bricks and voids behind the manhole wall, leading to infiltration, odour nuisance and road subsidence.
- Biogenic sulphuric acid corrosion
- Groundwater infiltration through walls or joints
- Loose bricks or washed-out joints
- Damaged base and flow channel
Manhole coating Chemically resistant
After cleaning and surface preparation, we apply a protective coating to the walls and base.
GRP renovation Glass-fibre reinforced
A glass-fibre reinforced plastic lining that makes the manhole watertight and structurally sound again. Fully chemically resistant and resistant up to 102.2 °C, making it suitable for industry as well.
Geopolymers Structural repair
A mineral mortar applied to the manhole wall for structural reinforcement. From a layer thickness of 2.5 cm it is a structural repair. CO₂-neutral and suitable for large manholes, chambers and industrial applications.
Base and flow channel
We also repair the base and flow channel, so wastewater flows smoothly.
