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.Â Â 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 itâ€™s way to appropriate storm drains.

Here is one of many examples of a drainage construction project we completed on Brandon Road in Pleasant Hill:
We will construct a drainage system around your entire home.
The drainage system consists of two pipes in a rock filled trench.Â One is perforated, to collect sub-surface water and the other is non-perforated, to collect water from the roof downspouts.Â 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 30 inches 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.Â The trench will then be then backfilled with drain rock.Â The rock we recommend is Class I, Permeable Type A drain rock per the California State Specifications.Â 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.Â This permits a four inch blanket of rock on each side of the four inch perforated pipe.
The system will discharge 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.Â 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.Â 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.
We will remove and replace the concrete/brickwork around the house as necessary to install the drain.
We will lift the left side of your home from the fireplace to the rear corner, and along the rear up to the right side porch/addition, and interior to make the floors more level.
We will record the differential elevations of your home on a rough plan before leveling and after leveling so you have a record of what was done.
Your home will be leveled from its existing foundation and no additional foundation work is included in this recommendation.Â As the house is raised, a crack will appear between the top of the foundation and the framing.Â We will grout this crack as necessary, with a high strength non-shrink grout, to support the house but it will be visible and will need additional cosmetic work later which is not included in our estimate.
We will replace the wood underpinning blocks with adjustable steel piers and extend the foundation bolts as necessary to provide anchorage.Â If the foundation bolts are missing or for some reason cannot be extended, we will secure the frame to the foundation with another method suited to the particular construction of the building
