The territory of Contra Costa County is very diversified: the city communities of Martinez and Crockett and the hills of the state of Walnut Creek, Lafayette, and Orinda. Houses constructed in the areas experience varying soil behavior; the soils in these areas are usually clay-laden and thus tend to swell and contract with the seasons, the old and compacted fill tend to sink, and the hillsides where the soil is prone to gravity as well as water movement drive the soil downward.
There are usually some small indicators of soil movement like interior cracking in buildings, slightly inconsistent floors, or moving trim, but these are usually subtle. Saturation of soil may lead to weakening of slab support in the creek adjacent areas such as those in and around Walnut Creek or Marsh Creek. In the hilly cities like Orinda or Moraga, the movement of the slope in the natural surroundings causes the lateral pressures under the foundations.
There are houses that require deeper repairs. Deep or extensive movement of soil causes us to apply foundational reinforcement which is meant to stabilize the slab forever. These involve the pier systems, deep soil injections and load bearing support based on the soil type.
The techniques prevent seasonal fluctuations in moisture, swellings of clay as well as movements of hillsides so that these residential buildings will be suitable to the changing topography of Contra Costa. This increases the strength of the structure in its most profound level to avoid frequent settlement.
The current slab needs to be analyzed before expansion of a home so that it can be sure that it can hold additional structural weight. This part provides the reason why additions in Contra Costa, particularly in the hilly or the soft-soil regions, need to be evaluated and strengthened to have foundations.
We determine the strength of soil and integrity of slabs prior to construction.
Before the addition of rooms or second stories, the homes constructed on fill or clay might require strengthening.
Strong foundation at the initial phase will minimize risks that will be faced in the long term once the addition is complete.
We are trusted by homeowners in the county as we are not only interested in cracking up the slabs, but also determining the cause of the movement. We adopt modern diagnostic equipment in studying the behavior of soils, moisture and the distribution of loads.
The indications that are likely to show that you have a slab that requires repairing include:
We also offer long-lasting and accurate repairs to bring stability.
The first thing that happens when the soil is shifting under the house is the appearance of cracks. The cracks also widen in areas of the city of Contra Costa that are heavy in clay as the soil absorbs water which then dries up.
The reason behind cracking is determined by our team, its depth and direction are assessed, and the foundation is stabilized to eliminate additional destruction. Early sealing of cracks helps the homeowners to save expensive structural complications and increase the life of their slab.
We’re here to help! Swiftly addressing these concerns is key. Our experts will promptly inspect and repair your foundation, ensuring the lasting strength and safety of your home. Reach out without hesitation for reliable assistance.
