Galvanized steel push piers transfer a structure’s load to soil that can support it. Push piers stabilize and re-level settled foundations. The piers are driven into the ground using the structure’s weight and a hydraulic ram until they reach the load-bearing strata. Once they’re in place, synchronized hydraulic cylinders raise the building back to maximum practical recovery. In other words, the building is leveled as much as possible without causing structural damage. Other names for steel push piers include piles, push piles, and resistance push piers.
Galvanized Helical Piers
Galvanized helical piers are shaped something like giant corkscrews. They’re mainly used for new construction projects requiring a deep foundation. However, they’re also sometimes used for underpinning structures that are too lightweight for steel push piers. The piers are turned into the soil until they reach the required depth and torque determined by a geotechnical engineer.
Polyurethane Injection – Tripping Hazards & Deep Injection
Uneven concrete sidewalks, driveways, pool decks, and patios are a trip hazard and a liability. You could face an unpleasant lawsuit if someone trips and gets injured on your property.
Polyurethane injection is a way of quickly lifting and leveling uneven concrete slabs. Most jobs take only a few hours, and then 15 minutes after the repair is complete, the slab is ready for use again. It’s less expensive than digging up and replacing the concrete and lasts longer than mudjacking. The general procedure is as follows:
Small, dime-sized holes are drilled into the uneven slab.
The polyurethane foam is injected under the concrete, expands to fill all voids, and lifts the slab.
The holes are patched with a compound that matches the color of the slab.
New Construction Helical Piers
When a new construction project needs a deep foundation system, helical piers are a cost-effective alternative to traditional concrete piers. Installation is quick, doesn’t require heavy excavation, and has minimal disruption.
Helical piers are turned into the soil until they reach the necessary depth and torque requirement specified by a geotechnical engineer. They come in various sizes and configurations and will support a deep foundation and prevent it from settling.
Helical tiebacks are steel rods that stabilize, strengthen, and straighten bowed basement and retaining walls. Installation is quick, done from inside the basement, and with minimal disturbance to your yard. Helical tiebacks can straighten a bowed basement wall over time without excavation or immediately with excavation.
Carbon Fiber Reinforcement
Carbon fiber is an extremely strong, non-stretchable material that’s just about impossible to break. That’s why it’s used in the construction of commercial aircraft. It’s also used to stabilize cracked and bowed concrete block and poured concrete foundation walls. Installation is quick, and there’s no mess to clean up. The straps attach to the footing, wall, and sill plate. Once they’re in place, they’ll prevent further movement in the wall.
Drilled Concrete Piers
Homes and other structures built on hillsides sometimes experience problems related to soil creep, a phenomenon where the soil at the top of a hill eventually ends up at the bottom. This movement in the ground can cause the foundation to settle or move laterally. Structures experiencing problems due to soil creep can be stabilized using drilled, cast-in-place concrete piers.
Drilled concrete piers are also suitable for retaining walls and new construction projects requiring a deep foundation. The piers are created by drilling holes into bedrock, inserting steel reinforcement cages, and pouring concrete into the holes.
Semi-rigid, hydrophobic polyurethane foams fill voids, seal seawall cracks and other defects, and stabilize the soil by forming a solid, impermeable mass. Polyurethane foams, along with good drainage, will extend the life of your seawall. We also offer seawall maintenance, including routine inspection, weep hole cleaning, and root eradication.
