Drainage construction in El Cerrito often involves drainage design in order to protect basement from flooding, dry out wet crawlspaces, avoid mud slide, protect 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 it’s way to appropriate storm drains.

Actual drainage job completed in El Cerrito:
Here is one of many examples of a drainage construction project we completed on Everett Street in El Cerrito:
We will construct a drainage system along the rear and both sides of the residence.
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 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 through two 4 inch solid pipes across the front yard to the street.
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.
We will remove and replace the existing rear deck boards as necessary.
It will be necessary to have 1 or 2 trees removed along the right side prior to installing the drain. The cost of tree removal is not included.
We will remove and replace the 33 feet long portion of damaged public walk along the front of the residence.
We will install 50 Simpson UFP straps in the sub-area, along the perimeter of the original portion of the residence to connect it to the foundation. We will strap the existing interior posts top and bottom.
We will install an access hole through the rear closet floor to inspect the sub-area of the addition, and make additional recommendations as necessary.
We will grade the sub-area for clearance on a time and materials basis
