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 Hayward:
Here is one of many examples of a drainage construction project we completed on Oakview Avenue in Hayward:
Per the report we will remove and replace the perimeter and interior foundations of the residence. The new foundation shall conform to the UBC standards for a 2 story home. On top of the new foundations we will secure a 2×6 pressure treated will with 5/8 inch anchor bolts.
We will lift the floors of your home, leaving it within 1 inch of level when we are through.
We will demolish the remainder of the fireplace as necessary to facilitate lifting your home. It will be up to you to contact a remodeling or fireplace contractor to either frame and patch the siding, or install a new metal insert fireplace unit. No repair to the existing hearth, mantle, or surround is included.
We will lift the front and rear porches as necessary and no other work to the porches is included.
We guarantee all of the above work will meet current building codes and pass local inspections.
This warranty is transferable to the new homeowner.
We will surround the new foundation with a perimeter drainage system.
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 be collected into a sump, from where the water will be pumped to the street.
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.
