Augercast piles are vibration free foundation piles that can be rapidly installed and are highly cost efficient in comparison to other piling options. Augercast piles are capable of carrying working loads up to 200 tons and lengths up to 140 feet or more depending on soil conditions. Smooth, powerful augers can install piles close to adjacent buildings and underground utilities without the risk of ground heave or settlement of existing foundations.
Installed by soil extraction, continuous flight augercast piles are available in a range of 12" – 42" diameters. First, the auger advances to the depth determined by geotechnical design requirements, removing little, if any, soil. Concrete is then pumped under pressure down the hollow stem of the auger to the bottom of the hole. Once pumping starts, the auger is progressively withdrawn, bringing soil with it. These carefully-controlled, simultaneous operations maintain the drilled hole profile. Using a high cement concrete and a plasticizing additive ensures complete integrity of the pile, even in very unstable ground.
When the auger and its load of soil are finally removed, reinforcement is placed in the concrete pile to meet design requirements.Hardman Construction’s quiet and efficient augercast drilling equipment is beneficial for use in even the most sensitive neighborhoods since the noise and vibration associated with driven piles are eliminated. Concrete mixing and pumping operations can be located away from the point of drilling, resulting in minimal disturbance in congested areas. Using our specialty equipment, augercast piles can be installed in areas with restricted headroom by adding additional auger sections to achieve greater pile lengths.
 H-piles |
In addition to our expertise in constructing augercast piles, Hardman Construction uses a variety of traditional driven foundation pile types to carry loads to underlying hard soil or rock layers for building and infrastructure projects. Timber piles, H-piles and pipe piles are suitable foundations for many types of land and marine-based structures. Each of these pile types offers unique benefits, and the decision about which type to use should be made after carefully considering the loads to be carried, structural and soil requirements and budget constraints. We often assist engineers during the initial planning stages of a project, ensuring its overall success.
 Mini pile installation |
Mini piles are high capacity 5" - 12" diameter drilled and grouted-in-place piles designed with steel reinforcement. Mini piles — also known as micro piles — can be used for new construction, remediation or enhancement. Mini piles are rapidly gaining in popularity for use in urban areas, locations with low headroom and in other places where heavy machinery cannot be used. They are an ideal alternative for underpinning and emergency repairs since they’re well suited for the most difficult natural or artificial ground conditions with little to no vibration or disturbance to existing structures.
 Helical foundation anchor installation |
Helical foundation anchors are another vibration-free foundation option for new construction or restoration requiring little space for installation. These anchors are screw pile foundations installed vertically through problem soils until load-bearing soils are reached. They protect new structures built on marginal soils and serve as underpinning to stabilize and restore slabs damaged by expansive soils, erosion or poorly-compacted fill soils. Installed laterally as tiebacks, helical foundation anchors can stabilize walls that have been improperly constructed and can restore walls that have been damaged by poor drainage or expansive soils.
Hardman Construction installs different types of drilled and driven earth retention systems including steel sheeting, soldier piles and wood lagging, tangent augercast walls, soil nail walls and earth anchors. Installed in all types of soil to provide horizontal and vertical restraint of earth, water or existing structures during excavation and construction of below-grade facilities, our earth retention systems can be installed in top-down, cantilevered, braced or tied-back fashion to meet our clients’ specific needs.
 Soldier piles and wood lagging installation |
Soldier piles and wood lagging systems are commonly used and are extremely cost efficient. Soldier piles are driven or predrilled at intervals along the wall’s baseline. If a predrilled approach is used, holes are drilled, grout is placed and an H-pile is installed in the hole, thereby providing a vibration-free installation. As the excavation in front of the wall proceeds, wood lagging is installed between the soldier piles in lifts. Tieback anchors may be installed and stressed to provide lateral restraint.
 Tangent augercast wall installation |
Tangent augercast walls are constructed by drilling low-vibration augercast piles at spaced intervals followed by installation of additional augercast piles between those spaces. This forms a continuous wall, sealing off the excavation. While these walls may be tied back or internally braced, tangent augercast walls are often a good solution when seeking a vibrationless earth retention system adjacent to existing structures or critical utilities.
 Soil nail wall installation |
Soil nail walls are an excellent solution when vibration-free foundation installations are required such as construction next to existing structures, reconstruction projects and reinforcement of existing embankments. Soil nail walls are installed in a continuous excavation method whereby shallow 3' - 6' vertical cuts are made in the soil, holes are drilled for the nails, soil nail tendons are installed and grouted, a shotcrete layer is applied and bearing plates and nuts are attached. This process is repeated until the final grade is reached. The grouted nails increase the shear strength of the overall soil mass and limit displacement during and after excavation.
 Earth anchor installation |
Earth anchors can be used to limit lateral movement of retention walls or soils that have been vertically shored, allowing the face of the soil to remain free from obstruction. Earth anchors are beneficial when conventional tiebacks or excavation with internal bracing cannot be used. A variety of materials, designs and installation lengths are used depending upon the load to be carried and the bearing strength of the soil.
