To install waterproofing on 3 walls for a total of 100 linear feet would cost $386.00 plus 100 times $22.00 which equals.$2586.00. Add the cost of a discharge method for a complete system. Adding a sump pump installation as shown below the total cost becomes $2886.00

Discharge methods are:

• Sump pump system- Discharges at the grade line above the pump cost $300.00
