PLI Systems, has helped hundreds of home owners with needs from stabilizing foundations with underpinnings to mitigating landslides. With nearly 30 years of experience, PLI Systems has the expertise and equipment to handle almost any residential soil and foundation stabilization problem. We have gathered specialized equipment from all over the world and have hired experts from various fields to train our employees. From stabilizing settling foundations to remediating landslides, PLI Systems is the one company that does it all.

Here are some of the services we provide to homeowners:

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.

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.

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.

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.

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.
  • 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
    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.
