An extra thick clay liner on the pond side next to the house would be worth the extra expense. I put a double thick clay liner in front of my house that sits 5ft - 10ft from the waters edge. He house, sump pump, perimetrer drainage system does not operate unless there are very heavy rains and the creek is flooding which indicates that the clay liner is not leaking water out of the pond toward the house.
