CIPP renovation liners for pressure lines

CIPP (Cured in Place Pipe) technology has been used for renovating gravity sewers for almost 50 years. Using it on a larger scale to repair pressure pipes covers several years. In our country, this last application is only now beginning to break through to the awareness of awarding entities. This year, e.g. in Silesia, the DN200 water section has been renovated and there should be more and more such installations soon.
