Linde-Griffith Construction Co. realizes the importance of on-time project starts and early project completions. Linde-Griffith Construction Co. believes we demonstrate the care for our customers and the expertise for their projects better than anyone else does. To insure this, Linde-Griffith Construction Co. employs a strict level of control over all our operations.
Linde-Griffith Construction Co. is self-reliant. This is evidenced by every aspect of our project management and control, from our in-house capacity to mobilize cranes and equipment, to our on-staff construction and layout services, to our ability to adjust immediately to varying material requirements, to our daily supervision of each project. Linde-Griffith Construction Co. employs our own personnel and utilizes our own equipment, depending on no outside vendor to service our projects.
Linde-Griffith Construction Co., with our fleet of heavy-duty tractors and trailers, moves our own cranes and equipment, sometimes within hours of our customer’s order. Linde-Griffith Construction Co. is mobilized and ready to commence construction operations, often times, in less than one day after receiving the notice to proceed.
An owner of Linde-Griffith Construction Co. supervises each of our projects. This on-site executive management and supervision allows for timely, accurate, and committed field decisions. This practice further demonstrates to each of our customers that their project is being constructed by a professional pile driving company that has a vested interest in mutual success.
Driven piles are deep foundation elements driven to a design depth or resistance. If penetration of dense soil is required, predrilling may be required for the pile to penetrate to the design depth. Types include timber, pre-cast concrete, steel H-piles, and pipe piles. The finished foundation element resists compressive, uplift and lateral loads. The technique has been used to support buildings, tanks, towers and bridges. Driven piles can also be used to provide lateral support for earth retention walls. Steel sheet piles and soldier piles are the most common type of driven piles for this application.
Micropiles, also known as minipiles, (and less commonly as pin piles, needle piles and root piles) are deep foundation elements constructed using high-strength, small-diameter steel casing and/or threaded bar. Capacities vary depending on the micropile size and subsurface profile. Allowable micropile capacities in excess of 1,000 tons have been achieved.
Sheet piling is an earth retention and excavation support technique that retains soil, using steel sheet sections with interlocking edges. Sheet piles are installed in sequence to design depth along the planned excavation perimeter or seawall alignment. The interlocked sheet piles form a wall for permanent or temporary lateral earth support with reduced groundwater inflow. Anchors can be included to provide additional lateral support if required.
Anchors are stabilization and support elements that transfer tension loads, using high-strength steel bars or steel strand tendons. A full-length hole is drilled through the soil and into the bond zone in soil or rock using casing if necessary. Threadbar or strand tendon is inserted into the hole and the hole is filled with high-strength grout. Any casing used is then extracted. The length of bar or strand above the bond zone is covered by a bond breaker to eliminate load transfer above the bond zone. The anchor head is then generally tensioned and connected to the structure requiring the support.
Augercast piles, also known as continuous flight auger piles (CFA), are deep foundation elements that are cast-in-place, using a hollow stem auger with continuous flights. The auger is drilled into the soil and/or rock to design depth. The auger is then slowly extracted, removing the drilled soil/rock as concrete or grout is pumped through the hollow stem. The grout pressure and volume must be carefully controlled to construct a continuous pile without defects. Reinforcing steel is then lowered into the wet concrete or grout. The finished foundation element resists compressive, uplift and lateral loads. The technique has been used to support buildings, tanks, towers and bridges.
Drilled shafts, also known as caissons, are typically high-capacity cast-in-place deep foundation elements constructed using an auger. A hole having the design diameter of planned shaft is first drilled to the design depth. If the hole requires assistance to remain open, casing or drilling fluid is used. Full-length reinforcing steel is then lowered into the hole and the hole is filled with concrete. The finished foundation element resists compressive, uplift and lateral loads. The technique has been used to support buildings, tanks, towers and bridges.
Soldier Piles & Lagging
Soldier piles and lagging is an earth retention technique that retains soil, using vertical steel piles with horizontal lagging. Typically, H-piles are drilled or driven at regular intervals along the planned excavation perimeter. Lagging consisting of wood, steel or precast concrete panels is inserted behind the front pile flanges as the excavation proceeds. The lagging effectively resists the load of the retained soil and transfers it to the piles. The walls can be designed as cantilever walls, or receive additional lateral support from anchors or bracing. The technique has been used to provide support of excavation in many situations.
Helical piles, also known as helical piers, are deep foundation underpinning elements constructed using steel shafts with helical flights. The shafts are advanced to bearing depth by twisting them into the soil while monitoring torque to estimate the pile capacity. A thorough understanding of the subsurface conditions is necessary to properly interpret the torque conversion. After reaching design capacity, the tops of the shafts are bracketed to the structure's footing. The finished piles effectively underpin the footing, stopping settlement.
Soil nailing is an earth retention technique using grouted tension-resisting steel elements (nails) that can be design for permanent or temporary support. The walls are generally constructed from the top down. Typically, 3 to 6 feet of soil is excavated from the top of the planned excavation. Near-horizontal holes are drilled into the exposed face at typically 3 to 6 foot centers.
Compaction Grouting (Low Mobility Grouting)
Compaction grouting, also known as Low Mobility Grouting, is a grouting technique that displaces and densifies loose granular soils, reinforces fine grained soils and stabilizes subsurface voids or sinkholes, by the staged injection of low-slump, low mobility aggregate grout. Typically, an injection pipe is first advanced to the maximum treatment depth. The low mobility grout is then injected as the pipe is slowly extracted in lifts, creating a column of overlapping grout bulbs.
Jet grouting is a grouting technique that creates in situ geometries of soilcrete (grouted soil), using a grouting monitor attached to the end of a drill stem. The jet grout monitor is advanced to the maximum treatment depth, at which time high velocity grout jets (and sometimes water and air) are initiated from ports in the side of the monitor. The jets erode and mix the in situ soil as the drill stem and jet grout monitor are rotated and raised.
Secant or Tangent Piles
Secant or tangent piles are columns constructed adjacent (tangent) or overlapping (secant) each other to form structural walls that resist lateral pressures and groundwater inflow for bulkhead support, earth retention, groundwater control, or slope stability. The columns are constructed with soil mixing, jet grouting, augercast, or drilled shaft methods. Sequenced construction of the individual elements that comprise the finished barrier helps to ensure a tight seal between elements for complete water cut off.
