Where soil conditions are poor, quite often the only way to prevent leakage from a dam is with a dam liner. With the proper preparation it is possible to install a dam liners yourself. But there are some considerations:
- You must prepare the site, and there must be no water in it
- You will need a number of helpers, usually at least 1 person for every 8 m of dam liner that will have to be pulled. So if you are pulling an edge that is 40 m wide, we recommend at least 5 people help out.
- You will need to dig a suitable trench all the around to anchor the liner
- After installation you should cover or backfill liner to extend its life and protect the liner against UV degradation.
Multiple Piece Installation – On-site Welding
For very large liners, joining on site may be necessary. This is something that a professional must do as you risk leaks in the seams. A professional installation team from Fabric Solutions (or authorised installer), will be responsible for all on-site material welding. When directed by the professional installer, position the liners as explained above. Overlap panel edges approximately 200 mm.
