The different neighborhoods of Hayward, including the hilly streets of Fairview to the leafy areas around Burbank and the old-fashioned streets of the areas near the Mission Boulevard, have loose soils which vary across the year. Houses close to the Hayward Japanese Gardens in Upper B Street or on the sloping landscape of Garin Regional Park are usually built on heavy soils predominantly made up of clay that swell when it rains and contract when it dries up. In the meantime, those properties that are nearer to the industrial areas or to the reclaimed lands can be located on soil which has a different degree of compaction, which is likely to result in an uneven settlement.
In the neighborhoods such as Harder-Tennyson, Jackson Triangle and Southgate, there could be initial signs of settlement such as hairline cracks and small dips on the floor or even windows that do not open smoothly as before. Such little movements can be the precursor to the fact that the ground under the house is rearranging. Through close inspections and specific reinforcement strategies, we assist Hayward people owning homes to put them on track again and ensure that structural motion does not develop.

You have to make sure that your foundation would bear extra weight before you add a new room, convert a garage, or grow upwards. A lot of Hayward houses – particularly the older ones in Cherryland or long-established areas around Tennyson Road- are houses that were not originally intended to have big structural additions made.
We start with the analysis of load paths, stability of the soil, and the well-being of the existing foundation. Our team strengthens the places that will carry the excess weight to ensure that the future remodeling projects will be placed on a solid background. Having the right as the foundation, property owners will be able to make changes without worrying about the foundation keeping its proper hold and position.
Permanent underpinning solutions provide reinforcement to weakened regions and settlement prevention in the future. The soils of hayward differ considerably depending on the area, especially the hillside and clay-rich areas which is why stability over time is a critical component of safeguarding your home.
We stabilize those areas of the ground that have been most influenced by water, and regain the reliable year-round assistance.
In case some of the foundation has fallen more than others we level and stabilize the house so as to avoid new cracks and misalignment.
The properties close to Fairview or Garin may need deeper support to resist the pressure and the soil changes on the hills.

Beneath the surface, technical knowledge is insufficient, it should be precise, well planned, and not lacking in knowledge about the local soil conditions. We assess the whole system of foundation to find the safest and most efficient reinforcement plan.
Indications that your house might require underpinning are:
This will ensure that your home does not suffer permanent degradation by fixing these problems at an early stage.
Proper diagnosis is the first step towards every successful reinforcement project. Our team research on the state of soil, humidity, nature of foundation, and the initial construction plan of the house. In the residential places close to the Hayward BART, the old foundations might be experiencing some weakening caused by age, drainage adjustments, or previous settlement.
Using both the modern tools of diagnosis and the local knowledge will help us not only to find out where the foundation has broken but also why. Such a cautious consideration would guarantee that every foundational solution would be focused on dealing with the source of settlement and provide structural security on a long-term basis.
Had a great experience working with Kyndell from Golden Bay Foundation Builders. I recently purchased the home and was looking for help with earthquake retrofitting options. He inspected my foundation carefully and determined that past bolting was likely adequate. He had suggestions about monitoring the foundation. He was very thoughtful and detailed in his approach, and worked to determine what was best for the home. In this case, that meant no need for additional work now. But if I need any additional assistance in the future, will be calling him again.
