Avloppsrening med relining.
There are many elderly buildings, particularly those constructed during the million program, in need of renovations and plumbing replacement. An alternative to the traditional plumbing replacement is the relatively new and untested technique called relining. The purpose of the study is to thoroughly investigate the different types of relining that are currently available on the market to help enhance Peab?s knowledge before purchasing relining services. The theoretical part of this report is based on relevant information provided from companies, previous studies, investigations and reports within the area. A number of interviews with persons somehow connected to the relining business have also been done. The result is based on the made investigations and experiences various people have from working with relining. It is clear from the study that relining is a good technique if it is used and performed in a correct way and a big responsibility is placed in the hands of the person performing it. There are risks with relining and there are many cases that show a bad end product after relining. Furthermore is it hard to say whether is a good or bad alternative, since there are both good and bad results from using the technique. What can be said is that relining is a good complement to plumbing replacement and if companies based in the relining business may enter the negotiations in an early stage, the risk of problems may decrease considerably
