PlumbingWaterproofing & Water Intrusion4HighHomeowner$ implied
Waterproofing crew overcut sump pump basin liner holes, causing water ingress behind the liner, and the sump pump float cannot be adjusted to prevent water from reaching the gap.
No easy DIY waterproof sealant that reliably bonds to wet surfaces in a sump basin environment; existing solutions like Flex Seal or Bondo are not designed for permanent submersion or structural repair of liner holes.
