Ground Improvement and Subsidence Resources
Subsidence. Settlement. Ground stability. Geopolymer injection. Unless you have an engineering background, understanding subsidence, settlement, and geopolymer injection can be difficult. We've assembled a collection of settlement and subsidence resources for you to learn more about the causes, symptoms, and treatment options for subsidence and settlement.
Subsidence and Settlement
Ground stability issues occur most commonly due to subsidence and settlement. Both subsidence and settlement are forms of soil displacement that lead to elevation changes. Simply put, subsidence is when the elevation of land is lowered due to underground changes. Learn more about subsidence and settlement.
Causes of Settlement and Subsidence
In the US, 80% of subsidence is directly related to groundwater pumping according to a report from the United States Geological Survey. There are several potential causes of subsidence or settlement of the ground underneath a property. Learn more about the most common causes of settlement and subsidence.
Common Signs of Subsidence
Subsidence comes with a variety of warning signs. Some of the most common signs of subsidence or settlement under your home are cracks in the walls, sinking floors, sticking doors or windows, and cracks in concrete driveways or patios. Learn how to spot the common warning signs in your home.
California Subsidence Maps
While we can’t map all of the causes of subsidence in the US, the United States Geological Survey works to document the most common cause of subsidence in the US. The maps on this page show where subsidence is known to be an issue and has been measured over the last twenty years. Download a map of known subsidence areas in California.
Explore Treatment Options
When you notice some of the signs of subsidence, it can be an overwhelming problem to deal with. If you don't know about geopolymer injection or underpinning, learning about your options is the first step. To get started, read more about your options for treating subsidence and settlement on your residential property.
Choosing a Subsidence Contractor
With so many choices, it’s important to understand how to make the best decision when it comes to choosing a ground improvement contractor. Ultimately, your decision should be based on your specific situation. Learn more about the six key considerations for choosing a contractor to fix your subsidence.
What to Expect During Treatment
What is it like to treat your home for subsidence? Our global team put together this short video to help you understand what to expect from Geobear. When we come to work on your property, it will be much like the video. This was created on a live project over the course of one day and the procedure will be similar on the majority of projects.
Geopolymer vs. Underpinning
How does geopolymer injection compare to the most common solution for subsidence or settlement? Check out this simple table to compare geopolymer injection to underpinning. Learn more about both options and compare process, costs, disruption, and more with our simple comparison chart.
Primary Methods of Underpinning
Underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning typically involves extending the foundation depth or distributing the load across a greater area. In order to choose the correct method, you need to understand the current situation and any problems concerning the entire foundation.
