  • foundation repair and maintenance

    Drilled and Grouted Tie-Back Anchors

    These can be from 1 inch diameter up to 8 inch diameter typically range from 10 feet deep to 100 feet deep in tension capacities of a thousand pounds to 1 million pounds.

  • pile driving new support beams

    Helical Anchors and Piles

    In the right soil conditions these are quick and efficient at developing tension or compression loads from a thousand pounds to 500 thousand pounds.  Depths typically range from 10 feet to about 100 feet deep and can be installed vertically or horizontally.  Square shaft helices come in 1.25”, 1.5”, 1.75”, and 2.25” material. Pipe Helices are made in many sizes such as 2-7/8”, 3-1/2”, 4”, 5”, 6”, 7”, 8”, 9’”, 10”, 12”, 14”, 24” diameters.

  • hillside remediation and landslide prevention

    Landslide Remediation / Hillside Stabilization

    Whether they were created by acts of nature or caused by breaking of water lines, PLIsystems has many tools and equipment to repair the landslides.  We incorporate tie-back anchors, drill piles shotcrete, soil nails and many other techniques to solve the problem.

  • retaining wall repair and maintenance

    Wall Construction

    Walls maybe built with driven pipe piles, driven wide flange piles drilled piles tie-back anchors, concrete or shotcrete, soil nails and shotcrete, gabion baskets, small concrete blocks or large concrete blocks such as ultra-block, or other geo-grid.

  • foundation repair


    Underpinning is the process of strengthening the foundation of an existing building or other structure. Underpinning may be necessary for a variety of reasons:

    • The original foundation is simply not strong or stable enough.
    • The usage of the structure has changed.
    • The properties of the soil supporting the foundation may have changed (possibly through subsidence) or were mischaracterized during design.
    • The construction of nearby structures necessitates the excavation of soil supporting existing foundations.
    • To increase the depth or load capacity of existing foundations to support the addition of another storey to the building (above or below grade).
    • It is more economical, due to land price or otherwise, to work on the present structure’s foundation than to build a new one.
    • Earthquake, flood, drought or other natural causes have caused the structure to move, thereby requiring stabilisation of foundation soils and/or footings.
  • foundation repair and construction


    Micropiles, also called mini piles, are often used for underpinning. They are also used to create foundations for a variety of project types, including highway, bridge and transmission tower projects. They are especially useful at sites with difficult or restricted access, or with environmental sensitivity.[8][9] Micropiles are made of steel with diameters of 60 to 200 mm. Installation of micropiles through top soil, sand and cobblestones overburden and into soil rock can be achieved using Air Rotary or Mud Rotary drilling, impact driving, jacking, vibrating or screwing machinery.

  • landslide prevention and erosion maintenance

    Soil Nails

    Soil nailing is a construction technique that can be used as a remedial measure to treat unstable natural soil slopes or as a construction technique that allows the safe over-steepening of new or existing soil slopes. The technique involves the insertion of relatively slender reinforcing elements into the slope – often general purpose reinforcing bars (rebar) although proprietary solid or hollow-system bars are also available. Solid bars are usually installed into pre-drilled holes and then grouted into place using a separate grout line, whereas hollow bars may be drilled and grouted simultaneously by the use of a sacrificial drill bit and by pumping grout down the hollow bar as drilling progresses.

Commercial Projects

Willamette Fishway

Installed case micropiles to support a fish ladder at Willamette Falls. Also faced gabion rock cages with shotcrete. All equipment, material ad personnel had to be transported to the site either by barge or boat.


Drove pipe piles to support new warehouse.


Supported existing foundations and added new deep foundations using micropiles. Difficult restricted access to work areas.
