Helical piers are a very reliable product. We use them all the time. There is considerable research that correlates the torque to capacity ratio. Torque is a very accurate way to predict capacity. If you are unsure, specify a test to prove it. They can be designed for lateral loads. They...
Look at the Helical Pulldown Micropile by AB Chance. This pile uses grout around the shaft to provide the lateral support to the shaft during an event. Also, Dr. Hesham El Naggar at the University of Western Ontario has done significant research into helical piers and liquifyable soils. Look...
Why not try a helical pier/anchor? They are good in tension and compression. You will have to sleeve it to get the lateral resisitance but you can do that with a Helical Pulldown Micropile from Chance. Used them before, works well.
Fortunately in Canada you cannot use the term "engineer" at all unless you are a registered professional engineer. It is protected under law.
Doesn't stop some people though, but they usually end up in court with a whole bunch of problems.
Ron has it. Get some geotechnical information. Ultimately the soil is causing the problem, so find out what is there. Once you have that, you can make a better decision on how to proceed or what is the best method of repair.
Get a deeper boring. If there is no idication where good soil is, how can one make a guess on a foundation type. Helical piles are certainly a good answer, but in order to get an accurate cost from a contractor, he is going to need to know how deep to go. Helical piers can be battered if...
I have been in engineering/marketing for years and the biggest thing to keep in mind, is tell people in your name what you do. Nothing more frustrating than looking for a company and not being able to tell from their name what they do.
Also think of the potential domain name, and make sure you...
We have used helical piers to support this type of application before. May have to use a helical pulldown micropile from Chance. If the shaft of the helical pier can't take the bending forces when the soil is removed, then an HSS needs to go around the pier with grout in it to support the...
Try the OSMOS monitoring system. It should do exactly what you are looking for and give you a lot more information.
Not sure who represents in your area, so google, "OSMOS Structural Monitoring".
grabens has it. Use helical piers and a grade beam structural slab system provided there is good bearing soil at a reasonable depth. We use helical piers in these situations all the time.
Follow the ICPI specifications. Interlocking pavement systems fail most often due to incorrect installation including base materials. It is not a failure of the technology. There is a ton of research that has been done to show that it works. Europeans have been installing interlocking paving...
