Drainage Contractors
Drainage construction in Piedmont often involves drainage design in order to protect the basement from flooding, dry out wet crawlspaces, avoid mudslides, protect the retaining wall, and stop the yard from flooding. Water under a house or home can be very damaging, causing mold, bad smells, mildew, and dry rot. Drain repair and drainage repair may involve the installation of French drain or French drains, and sometimes it is necessary to install sub drains, and a catch basin and sump pump to divert water from low areas under a home. Rainwater and stormwater should run off the roof through gutters and downspouts, onto concrete tile or through grates then into the French drain, through piping and find its way to appropriate storm drains.
As competent drainage contractors, we offer a professional estimate in Piedmont, provide advice on drainage design, provide an estimate or bid for your drainage job, and perform the work quickly and efficiently, with minimum intrusion on your lifestyle. Most drainage problems are too much for the do-it-yourself project. They often involve structural design, concrete pour into wood forms, underground drainage, and more.
Actual drainage job completed in Piedmont:
Here is one of many examples of a drainage construction project we completed in Piedmont:
We will construct a drainage system along the north side of your home with the exception of the 20 feet closest the northeast corner. The starting depth will be 4 feet, but will increase to 9 feet within the first 16 lineal feet.
The drainage system consists of two pipes in a rock-filled trench. One is perforated, to collect sub-surface water and the other is non-perforated, to collect water from the roof downspouts. At the upper end or start of both lines, as well as at the major corners, a clean-out will be provided so that both lines can be tested or cleaned as necessary.
The minimum depth for the perforated pipe will be below the grade of the soil under the house adjacent the trench, this system will not be lower than the lowest sub-area or living space, and both the perforated and non-perforated pipe will fall at least 1/8 inch per foot for the total length of the system to the point of discharge.
The perforated pipe will be installed on top of a bed of gravel, two inches deep, with the perforations pointed down. The trench will then be then backfilled with drain rock. The rock we recommend is Class I, Permeable Type A drain rock per the California State Specifications. The drain rock is clean gravel that varies in size from 1/4 to 1/2 inch.
The trench will be a minimum of 12 inches wide. This permits a four-inch blanket of rock on each side of the four-inch perforated pipe.
The system will discharge through a 4-inch solid pipe across the front yard up to the stairs that lead down along the left side of the garage to the street where we will attempt to find and connect to the existing drain pipe. If this is not possible at this location and depth, additional costs will be incurred.
We will remove and not replace a strip of the concrete patio next to the house, and the path leading up to the lower stairs.
In conjunction with the above, we will connect downspouts 1,2, and 3, and two new 8-inch surface drains to be installed in the low areas of the front yard, into a separate 4-inch solid pipe that will connect to the above-mentioned drainage system.
We will plug the existing pipe that leads away from the sump adjacent the laundry room and fill the sump hole with concrete.
