Earthquake bolting, also known as seismic retrofitting, involves adding reinforced elements to older foundations that were constructed before seismic building codes were enacted. The goal of earthquake bolting is to improve the building’s ability to withstand ground motion during an earthquake and reduce the risk of collapse or other structural damage. Common retrofitting techniques include bracing and bolting the building’s wooden frame to the foundation or adding steel plates to prevent the home from slipping off its foundation. While not all structures require retrofitting, it is important to ensure that older structures are properly evaluated to determine if retrofitting would benefit during seismic activity.
Helical piers, also known as helical piles, are deep foundation systems used to support structures in a wide range of soil conditions. They are composed of steel shafts with helical plates attached to them, similar to a large screw. The helical piers are installed by twisting them into the ground using hydraulic equipment, allowing them to anchor securely into the load competent soil. These piers are commonly used for applications such as residential and commercial foundation repair, new construction, and structural stabilization. Advantages of helical piers include their ease of installation, minimal disturbance to the surrounding soil and environment, and ability to provide immediate load-bearing capacity.
Slab replacement is the process of removing a damaged or cracked concrete slab and installing a new one in its place. A concrete slab replacement is typically necessary when the existing slab has significant cracks, has shifted or settled, or has become uneven. It may also be required when the current slab is unable to support the load it was designed for, or when water is seeping through the slab and causing damage to the structure. This is done by demolishing the old slab, excavating the area to the required depth, installing sand, rebar, moisture barrier and pouring a new concrete slab.
Foundation replacement refers to the process of completely removing and replacing an existing foundation of a home. This is necessary when the foundation is damaged, heavily deteriorated or weakened beyond repair, which can lead to structural issues and compromised safety. Foundation replacement involves removing the existing foundation, trenching soil, installing reinforced steel and pouring a new footing and foundation walls. Signs that a foundation may need replacement include noticeable cracks in the walls or stucco, sagging floors, and doors or windows that don’t open or close properly
Home leveling, also known as house leveling or foundation leveling, refers to the process of correcting the leveling of interior floors. This is often necessary when a home’s foundation has settled or shifted due to soil movements, drainage related issues, or other environmental factors. Home leveling involves hydraulically lifting the framing of the home from the crawlspace and installing new piers, posts and/or additional sill plates to newly adjusted heights.
A pier and post system is used to provide a stable foundation for floor and load bearing wall support. Piers are concrete pads placed in soil and provide a level and stable surface for vertical wooden posts that are then anchored or strapped to the piers. The wooden posts typically support a larger girder beam. This is designed to support the floor joists and internal foundation framing assembly.
