Basement Drainage Lines Cost
Construction ITEM DESCRIPTION
Construction unit cost for installing perforated drain lines along basement walls. This work is done from the inside on older buildings that have inadequate exterior foundation drainage.
One lineal foot of foundation wall drainage.
We figure 16 lineal feet of drain per hour for a crew consisting of one skilled worker and two unskilled ones.
NOTE-- You may need to use a smaller crew, but the person-hour figures ought to be about the same.
The cost includes one foot of perforated drain line, some gravel to cover it, and 4" concrete to replace the floor material that was removed. We figured the concrete cover for about a 9" trench width-- increase the material by 33% if you dig a 12" trench instead.
NOTE-- This price does not include drainage to daylight or a sump pump to remove the water collected by the new drainage system.
We suggested the entire basement perimeter. You can adjust the length if the entire cellar does not require drainage.
Source of Construction Pricing
Based on job cost data from several basement remodeling projects done by Turtle Creek Construction.
Most of the projects were in buildings built around the turn of the century, so the concrete flooring was easily removed. If you are doing this in newer concrete floors, you'll probably need a jackhammer and some additional labor for removing the old concrete.
