foundation underpinning
Foundation underpinning is the process of strengthening an existing foundation through the use of different materials such as steel piers and concrete. These different types of materials are placed in the ground below the existing foundation, into either soil or bedrock to provide stronger support for the foundation, anchoring it into place to prevent any movement in it that can affect the structures built on top of the foundation. Our expert team can help inspect and plan the repair of your foundation, using new techniques and technology that make the job easier, quicker and more cost effective.
Inspections Before any construction can begin or even planning can commence, our technicians need to inspect your existing foundation to see where and how it needs to be supported. There are tell-tale signs around your foundation that our professional technicians will be able to spot, allowing them to start to make a plan for the repair process. We have access to many different products for use in repairing foundations so its an important opportunity for our team to see which areas will need which products to get the best result for you. We are careful to inspect closely to spot every issue and thoroughly resolve them. Applications Foundation underpinning can be applied to many different kinds of foundations of all sizes and applications. At San Francisco Foundation Specialists, we have a broad range of products available for use we can apply them differently to each project as required, allowing us to be able to assist in a huge variety of foundations of all shapes and sizes. Because there is a wide range of products available, we're able to apply these products and techniques to residential, commercial and industrial applications regardless of their size and complexity, so for your upcoming repair project make sure you consider our underpinning service. Methods The method chosen for your specific job will depend wholly on what has happened to your foundation. In most cases, there isn't one method that applies to all, which is why it's so important to have a professional that can properly identify the problem that's being caused to your foundation so they can select the correct repair method. Once they have established if the issue is a fracture that has developed in the bedrock, or perhaps the soil is shifting due to moisture or erosion, they can then use any one of our products to start to stabilize the foundation. Products Every site for construction is different and varies in its own way, which is why we have multiple options available to cater to each unique foundation type. Depending on the individual needs of the project, we can provide helical piers, push piers, and even concrete permeation if required. These products can be used individually or in conjunction with each other to provide the most secure solution for your site, preventing it from shifting and securing the foundation and the construction built on top of it. We aren't in the business of quick fixes, we want to provide a permanent and stable solution that will stand the test of time. |

How do you underpin a house foundation?
Underpinning a structure is a very involved project that will heavy equipment to install foundation piers beneath the footer of a home. If Underpinning piers are not properly installed, then further damage may occur in the future. A foundation contractor and their crew will install anything needed to repair your foundation, and they will know what needs to be done. Contractors will often use a series of piers that are placed beneath a structure either through pushing, drilling, or pouring them below the foundation walls. These piers will create a new firm foundation for the structure to rest on, and will provide support so that no additional settling or shifting occurs.
There are a number of different methods that can be used to underpin a foundation that will all vary depending on the damage, soil conditions, and the amount you are willing to pay. There are steel piers, concrete piers, high-density polyurethane foam, and spot piers that can be installed to a foundation to give extra support. Structures that sit on loose or moist soil may need stronger and deeper support as soil conditions could be more challenging. Dry clay like dirt may not need as deep of supports as the soil can better support piers. The most popular underpinning micro piles that are available are steel helical and push piers. Although push piers and helical piers will both perform slightly different, they will provide the same results. Both of these piers are made of galvanized steel to protect them from rusting, and will be more expensive than other grout or concrete support systems. However, steel helical and push piers will both be permanent and sturdy supports for residential and commercial buildings in any location.

How long does it take to underpin a house?
Underpinning a foundation can be a lot of work to prepare the area around a structure, dig down to the foundation, install the piers, and then clean up afterwards. Normally the repair process can take about 2-3 days to complete the entire project. However, there are a number of issues that may happen that will cause construction to take a bit longer than usual. Plants, trees, concrete, or any other type of landscaping may need to be removed from around the structure before crews can begin to dig down to the foundation. Bad weather can also cause delays as it may create poor working conditions. This could be rain, snow, or extreme heat. Also the square footage of a structure will change the time to finish construction Foundation repair could also take longer because some structures may have deeper footings because of a basement.
Foundation repair will be a long lasting fix that will stay firm over time. It is estimated that steel piers will last for about 150 years before rusting or giving out. Galvanized steel will allow the piers to avoid damage from rust and corrosion over time making them great for the long term. Grout piers may be a bit cheaper, but they will support less weight. Nevertheless grout piers will still last a long time. It will be best to ask your contractor based on the conditions of your foundation how long your piers may last. However, you will not have to worry about them giving out any time soon.
