Thank you!

SlideRuleEra this is what i was worried about. The new piles will be going into the mat pressure zone that you showed.

Thanks for the responses. The piles nearest the mat are single piles and not groups. So the spacing is relatively far between the piles. I was thinking the existing mat is wide so the influence goes deep as well.

Auger cast in place. 2foot diameter drilled out then grouted then rebar placed inside. Mostly single piles nearest the mat

Next door is an existing mat foundation about 4.5 feet thick and embedded a couple feet. Designers are planning 20-80 foot deep auger cast piles very nearby. Maybe 5 feet away? I’m concerned about any effects on the existing mat when we put in the ACIP. Any suggestions?

Thank you all

Hello I see in ibc 2012 1810.4.10 says 4. Subsequent micropiles shall not be drilled near elements that have been grouted until the grout has had sufficient time to harden. I take that to mean that if you drill and grout a micropile, you can't drill another one nearby and within some time. Is...

anyone have recommendations on getting testing equipment for shear wave velocity testing to determine IBC site class? id like to get the equipment and do it myself. specifically from the surface not down the hole. pros/cons?

thank you for the replies. yes the bearing and strength of the soil is not really the issue. just the protection of the surface from loose gravels and erosion. how long could we expect the sprayed asphalt to last under these conditions? right now the sprayed on product in use needs to be...

so there is info on the starting dimensions for the liquid limit grooving tool but is there an official replace the tool guideline? thanks

update: m% Dryden 76.6 38.3 53.2 44.4 40.1 50.2 32.3 52.2 giving specific gravity around 1.1 and still no max dry den. but at least we are back into a more "normal" range. like i said earlier the soil compacts well at very high moisture and was not muddy or mushy at all. just by...

Ok sorry guys... I think I have to chaulk this up to lab error. After I got those results I asked them to keep drying the soil and pound some proctors alog the way... I don't have the exact numbers in front of me but... The max dry den laity kept going up as it got drier. Last I saw was around...

well im not going to use it anymore... im just curious if it is even possible to have these results
