The topography of Pleasanton is varying between the smoothly pitched houses at Kottinger Ranch and Ruby Hill to the older flat houses located at the area of the Downtown Pleasanton, Valley Trails, and Del Prado. The behavior of soil is also very diverse. Areas with high clay content increase in the rainy season and shrink in dry seasons, whereas resident areas close to Arroyo del Valle or Bernal Avenue experience issues like retention of moisture, loosened soil formations, and subsidence. The combination of old and modern subdivisions in Pleasanton contributes to the ground stability being one of the primary priorities in ensuring structural safety.
Small symptoms such as sinking walkways, shifting pavements, or cracks along the lower walls are frequent signs that show that the soil is losing its capacity to sustain the weight in a constant manner. Our team offers soil stabilization solutions aimed at stabilizing the ground underneath the Pleasanton properties to minimize the chances of settlement and permanent damage of the foundations.

Concrete blends reinforce soil by forming a more compact, homogeneous base that is not compactible and does not expand due to moisture. This technique is especially used in older Pleasanton neighborhoods in the process of enhancing ground reliability under foundations and exterior slabs.
We test the soil composition, calculate the optimal ratio of the mix, and cement stabilization in the zones where the ratios and moisture of the soil should be improved considerably.
Lime stabilization suits Pleasanton heavy Clay areas. Our preliminary step is to measure the plasticity of the soil and the moisture content of the soil given the fact that we can decide on the amount of lime that is to be used to strengthen the soil appropriately.
Clay minerals are reacted with lime and this decreases the swelling during wet seasons.
Strengthened soil is able to support better the structural weight.
When treated, stiffer soil will be more resilient to the seasonal cycle of moisture.

Pleasanton is located in an area where the stability in the soil has a direct influence on the seismic performance. Weak or soft soils may enhance structural stress in the course of movement particularly in multi-story or soft-story buildings.
Owners of properties tend to contact them when they observe:
We strengthen the performance of the soil to enable the structure withstand seismic activity, and remain permanently aligned.
Polymer-engineered treatment is an effective modern technique of soil stabilization without the use of heavy materials. These polymers hold the particles in the soil together making it stronger and less able to absorb water.
The technique is very useful in Pleasanton regions that undergo moisture retention or frequent erosion. The stabilization of polymer assists in the ground support stabilization and decreases the risk of occurrence of soil movements in the future.
We were very happy with the results of our inspection with Ryan! He explained the settling in homes and what things we should look for, and was very professional, friendly, and efficient. Thanks!
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.
