Cost of installing and grouting vertical ground loops
NetLoopCost is spreadsheet to compute the cost of installing and grouting vertical ground loops (total Loop Cost with drilling, piping, and grouting costs).
In column B, input U-tube pipe size and bore diameter in inches, cost of grout per 50 lb. Bag of bentonite, cost per 50 lb. Bag of silica sand, cost to drill and insert the U-tube per ft., cost per ft. of HDPE pipe, grouter hourly wage, and grouter bag handling rate per hour. The last three items are results of required length of bore for ground loop when thermal conductivity of grout is considered.
Output includes amount of materials, costs for grouting and total loop costs.
