Drainage construction in Tiburon 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 Tiburon:
Here is one of many examples of a drainage construction project we completed on Juno Road, in Tiburon:
We will connect all the downspouts along the rear and both sides of the residence into 2 solid pipes and run them directly to the street. We will also install several 6-inch surface drains along the path of the pipe. 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.
There appears to be enough slope on the property to accomplish the above-mentioned work, if for any reason there is not, a sump pump will be needed at an additional cost.
In conjunction with the above, we will construct a drainage system along the back and right sides of the residence, ( a portion of the system located along the rear will be constructed along the edge of the back patio.)
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 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 construct a drainage system along the rear and right sides of the back yard to collect water that flows down from the neighboring properties.
