What happens if I puncture the floor membrane and how much is the repair cost?
If it's a studded plastic cavity drainage membrane on the floor and you puncture it, in principle the waterpoofing protection will fail. In practice the consequences will depend on the extent of the underlying water pressure and the efficiency of the sump and pump drainage system which is designed to remove any running water that may occur.
If this is working properly and has the required capacity, it should give some protection against water breaking through to the finished floor level. But if the property is susceptible to floods, this could easily be overwhelmed.
If there's no sump and pump, you potentially have a serious problem.
It calls for a specialist surveyor with the necessary waterproofing qualifications to assess the damage, advise on the best method of repair and provide a quotation.
