Manhole base liners
The plastic or glass fibre reinforced (GRP) manhole bottom is the ideal protection for the concrete shaft in the area of the channel and the berm from the negative effects of sewage waters.
The shaft bottom has excellent hydraulic properties and is found to provide smooth sewage system operation, easy maintenance, cleaning and wear resistance.
High-quality materials and manufacturing processes guarantee a long service life.
A huge range of variants can meet every customer requirement.
WHY PP/GFK MANHOLE BASE LINER?
- resistance to corrosion and mechanical action
- hydraulically optimal shapes
- minimum maintenance requirements
- seamless bonding to concrete
- possibility of connecting all types of pipes
- Infinite variability in Fibreglass laminate products
Manhole base liner from PP (PE)
Large range of standardized types in dimensions DN 800, DN 1000 and DN 1200, channel diameter DN 150 to DN 400.
We manufacture manhole base liners made of thermoplastic materials – polypropylene (PP) or polyethylene (PE) – using the wacuum heatforming method.
