Earth Contact Products introduces a new foundation repair underpinning bracket for micropiles. This bracket was designed to be used with TEI's MP-250 Rock Drill.

bullshit, your pumping watery grout into a hole like that is nothing...

i would have cut core holes and used all thread to hold a series of lifts brackets on a single pieve of angle gaped at crack and lifted with rams. polyurathaned the cracks. then add footings,some cheap jacks, removed the rams and poured 6000 lb mix on a heavy duty cage. done and solid not this little stuff

i wanna see numbers...what could a small diameter pile really support anyway? i'd like to know.seriously?

40mm hollow bar micropiles have an ultimate capacity of 148 kips. Obviously this is a fairly high capacity for underpinning. We also do not recommend using "cheap jacks" for underpinning but rather using high quality hydraulic cylinders that are manifolded together to provide an uniform lift. While the micropile rod is slender, the grout column that is created around the rod is not. Once you see micropiles installed I believe that you will change your mind.

i've underpinned malls before, and this isn't how i did it.

please correct me if i'm wrong. i'm being serious because i'm always learning.

what maes this so special? your putting a piece of steel pipe in the dirt. pressing it in with a ram, then putting this high speed/carbon allthread into the pipe...

thats what i don't get....the allthread is supposed to provide some upward tension or something? and if so, how much could you get from that little pilon?

and for lat restraint, too thin

The micropile is rotated into the soil, through the underpinning bracket, and grouted the whole length. So, you will not just have a pipe with rebar down the center. You will have a grouted column with a structural member encased its complete length. The steel pipe at top only provides a conduit for the grout to the top of the bracketing system. The lift or stabilization will be preformed off of this encasement.

The micropile can drill through cobbles, debris and rock layers to provide support.

Wow yer getting the joj done right

[dekonfrost7]

@engineered11 the fact is that a 20-40 ton bottle jack is 1-2 hundred dollars and it will lift independantly from the other jacks in the lineset. sometime this is a serious advantage, when reorienting something...also you can pour with leaving them in place...that was my point, i just felt the need to clearify this point, so as to people believing you were som kind of expert or something...base on my choice of tooling differing from yours....

@lucy9359

about 30,000 more or less depending on what part of the country your in. i'm on the esat coast baltimore....

@dekonfrost7 what do u think it would cost us to repair our foundation the way you just described? the kitchen has sunk down about 4 inches on the old place but the repo will sell it to us for the place of the building lot....of course we have a company that can go in on it for us but not sure if it is worth it....some one cut out a window on the reno...already put new windows in did 95% of renos before they compromised the foundation????

I have been pushing cylinders and steel pipe in the ground for 10 years.... This is the most rediculous system I have ever seen!!!
