A helical pier is really a superior-ability deep foundation engineering very first invented in the early 1830's. It replaces foundation options like poured concrete or pushed piers and presents superb foundation guidance to any framework. They can be employed as ground anchors to aid guy wires, tie-downs, and much more.
Screw pile steel shaft sections are subjected to design and style parameters and setting up codes benchmarks with the area of manufacture.
Other negatives vs substitute pile selections dependant upon An array of aspects such as the availability of steel, familiarity of community engineers or building authority with helical piles, and many others.
Helical piers are also most popular in spots with restricted Place for equipment, building them well-suited to compact urban destinations.
Tim’s knowledge of the enterprise is exceptional, and all of his workers are first level. I will be recommending Techno Steel Submit Pikes Peak to all of my future consumers.
Could be galvanized, manufactured thicker or have anode methods additional to increase the lifetime of the piles by hundreds of years;
You will find several tasks wherever the soil circumstances would show more challenging than creating in an ocean. Recognizing that helical piles had been undertaking effectively in this type of hard surroundings, the engineering community inside the late 1800’s started to leverage helical piles mainland.
ECP’s patented Helical Pier helical piles Process completely stabilizes foundations, and we manufacture and engineer them to perform. Professionals mechanically “drill” the helical piers, also called helical piles, from the shifting soil to the secure, load-bearing strata.
They are really clean up – there is absolutely no predrilling or tailings/spoils, the pile is simply changed into the bottom;
A normal property can need to have among five to 10 helical piers. The amount of piers needed varies based upon the scale from the structure and its excess weight.
Calls for minimum amounts of typical tools like excavators and skidsteers to set up, minimizing mobilization expenditures.
Places which has a high water table will likely require further depths and regions at distinct altitudes call for supplemental thought.
In developing any foundation, It's a very best exercise to engineer into the weakest link and that is predominantly the soil, and thus it is highly advise to start with a geotechnical investigation and Evaluation.
My suggestions is all determined by my experience right here to the milder West Coastline where by the frost amount is all over a foot. There might be additional productive techniques to deal with protecting the Main when it should go as deep while you must.
