PMA-Liner-Manhole 

PMA-Liner with CORPROTECT full lining

Concrete and PREDL manhole-base-liner have always been the perfect match. PREDL's new PMA-Liner-Manhole System now allows for a fully lined manhole system without joint welding. 

The PMA-Liner-Manhole system features a lined joint connection with integral seal and load transfer. Bundling the PREDL manhole-base-liner with CORPROTECT and the new joint connection now also allows corrosion protection in the joint area. 

  • No more joint welding
  • Standard handling as precast concrete part
