Liner repair work maintains this lake

We were contacted by this lovely client who, in her 80’s, didn’t want the trauma of a rip-out and replace. This lake was lined with HDPE plastic not a long time ago, she had a bad experience with the contractor and we found this damage caused (probably) by ground movement. Our Firestone EPDM liner moves with the ground; HDPE plastic doesn’t as evidenced by the resultant tear. We dropped the level of the lake to get in and stick on a Firestone FormFlash patch which, whilst not warranted or recommended, appears to have done the trick! A little turf edge repair and she’s good to go.
