Heres an example of a foundation repair job we did in Livermore :
We will remove and replace the entire perimeter foundations of the original portion and rear addition of your home. We will also remove and replace all the independent interior piers.
The new foundations shall conform to the UBC standards for a 2 story home. On top of the new foundations we will secure a pressure treated sill with 5/8 inch anchor bolts. We will re-level your entire home to within approximately 1 inch of level. To accomplish this we will construct 2 jacking pads beneath the existing fireplace footing to allow us to lift it. No work to any porches, stairs, or utilities is included.
We will construct new retaining walls and a slab floor in the sub-area utility area.
We will surround the new foundations 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
