I had a company encapsulate my crawlspace with 20 mil liner. The liner installed has 3 dime size holes as well as a 4-5 inch gash they covered with tape. They now would like to cover the holes with tape as a fix. They also mentioned they are going to foam then since they have to come back. Is the only real fix for them to reinstall a new liner or is there an actual fix to this? What issues can I have in the future?
