    PE lining of pond - our trial pond at KC

    Hi,

    as mentioned in another thread I imported special equipment to do PE pond lining (or construction). We started working on our D1 pond 2 days ago to test how the system (and our equipment) works. The D1 pond was leaking again after it has been repaired twice. Now I give the PE system a try because if it proves successful I will not have to repair anything anymore for at least 10-15 years

    The basics of this PE-system are simple. As in our case we simply weld PE sheets (2mm) into the existing pond and create a "shell" or a "pond in a pond". As the outer structure is already there (normal brick construction) it serves as the support to hold the PE in place. The PE sheets are placed into the pond and there is some "overlapping"of about 20-30mm between the sheets. They are finally weld together with a welding rod. The first welding is done with a hot gas welding machine. The final layer for the strength is done with an extrusion welding machine. To finish the bottom of the pond we have worked about 10 hours. This was mainly because the shape on the bottom of our pond is a bit tricky and we needed to shape the sheets into place first.

    we expect to finish the pond beginning of next week (need to stop working on it because of many RDF orders he...he ) and fill the water in. Once everythings works well we will order the PE material in black colour and we can do pond repairs for customers. We were using the white PE because that's the only colour currently available. After filling the water the material will be closed by algae anyway but we do not know yet how long this will take. If we have the black material available it willlook much better right from the beginning

    Here are some pics of the project

    The corner of the bottom (will be closed by another layer later)


    I will post more pics and keep you updated about the results
    Cheers
