Drainage construction in Union City often involves drainage design in order to protect the basement from flooding, dry out wet crawlspaces, avoid mudslide, 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 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. Rain water and storm water 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.

Actual drainage job completed in Union City:
Here is one of many examples of a drainage construction project we completed on Perry Road in Union City:
We will construct a drainage system along a 19 feet long portion of the front side of your home.
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 the perforated pipe, a clean-out will be provided so the pipe can be tested or cleaned as necessary.
The minimum depth for the perforated pipe will be 3 feet or below the grade of the soil under the house 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 into a sump located on the left side adjacent to the front corner, from where the water will be pumped to the street. We will connect the downspout located at the front left corner and the pipe that comes from the left side yard into a solid pipe and run them across your front yard to the street. The sump will be constructed deep enough to accept future drainage from the rear yard.
The pump we will use is a high quality 1/3 H.P. 115 volt submersible with a 1 1/4 inch discharge. The performance rating is 42 GPM at a head of 10 feet.
A check valve will be installed in the discharge line to keep water from running back into the sump when the pump turns off. The pump does not pump the sump dry and there will usually be water standing in the bottom.
The installation will be made so that it will be as easy as possible to service or replace the pump when this becomes necessary
We will cut the sidewalk, install a drain pipe under the sidewalk and through the curb to discharge into the gutter and repair the concrete.
