This is not just our opinion, but also the opinion of many, if not the vast majority of, independent engineers (structural engineers and geotechnical engineers). A concrete pressed pile or push pile foundation repair consists of cylindrical concrete pieces, usually 6" in diameter x 12" in length, which are pushed or pressed down into the soil and below the existing foundation beams through the use of a hydraulic jack using the weight of the house.


These cylinders are considered precast concrete driven piles, which the building code says would need to be at least 8? in diameter in order to meet code (yes, without their explanation even going into calculations and formulas and complicated Engineering stuff, this system is code non-compliant already). The intended purpose of this repair system is that as you push down these round concrete sections eventually you will reach soil that is very hard or stiff, not necessarily rock (actually, most of the times it is not rock, especially in San Antonio).


Indicators on House Leveling Austin You Need To Know


Once you have reached this very stiff stratum of soil (supposedly), the hydraulic jack won't be able to keep on pushing the sections of concrete down because the force required to push the piles down is more than the proportional weight of the house; at this point, the hydraulic jack will start lifting (leveling) the existing foundation of the house.




There are different types of systems but all they are is mainly a slight variation of the same push pile or press pile foundation leveling repair system - pier and beam foundation austin. Some companies put a cable through the different cylindrical sections, other companies put a steel pipe at the bottom and then put the typical push piles on top.


The reason there are different systems that are basically slight variations of the original system has to do mainly with competition. Foundation repair companies need to differentiate themselves from each other because after all there are literally dozens and dozens of foundation repair companies in Austin and San Antonio, so they need to claim their system is better than their competitors.

Mostly all of these systems do not effectively repair or level a foundation because they mainly share the same flaw. This flaw is that the piles themselves are not deep enough and do not act monolithically (i. e. don not act as one piece), and because they are surrounded by bad soil, then the piles will be subjected to the same heaving and settlement that the original slab is subjected to.


There is a zone in the soil known by geotechnical learn this here now and Structural Engineers as the active zone. This zone is simply a certain depth of soil in which variations in moisture content (i. e. water) varies as the environmental conditions change (e. g. click to read change in temperature, rain, exposure to sun, etc.).


If the soil is dry then the soil (clay) will shrink and the foundation will settle; if the soil is wet the soil (clay) will expand and the foundation will heave. But the problem of bad soil in the active region also affects piers and pile foundations, regardless whether they bear below the active soil. foundation repair austin tx.

e. swelling of the soil pushes on the pile through skin friction), thus making the pile or pier heave up. Yes, you read right, the pile or pier will move up! The problem also with press piles is that although the piles are pushed into much harder soil (or so they claim), this soil is still bad soil within the active zone and therefore, will move up or down as moisture in the soil changes.
