    Curing of Shotcrete

    Hi BigH: I haven't been around for awhile, but kinda got an urge to have a look at this forum. Having done a lot of inspections of concrete over the years, it is a very common occurrence to encounter concrete not being cured. There are the various standard replies like "we used a curing...

    Quebec, Canada: Landslide

    This is obviously the famous quick clay of the St. Lawerence valley somewhat the same as the quick clays of Norway. Any takes by any body else?

    Ground Subsidence

    Hello Moe333: This strike me as a very interesting project. Is it done very often? I suppose it must be in which case there would be some peer information/assistance available. I would say you have a legitimate concern about subsidence. A lot depends on the insitu conditions and you have...

    Footing and Foundations on surface Bedrock

    Hi answersthatwork. You've got pretty massive bedrock that wouldn't soak much water, nor bump around too much from frost, I shouldn't think. Still, It would be prudent to drain the grade away from the foundations with impermeable soil, or synthetic and maybe add foam insulation, but thats...

    Welcome Ecanuck

    Gentlemen thanks for the welcome! I just got back from vacation - not cell, no computer, only a fishing rod. Ecunuck was just a quick choice to hint of my origions and like most maritimers I have returned here in the most prosperous area of Canada. Yea, really, see...

    Test Pits May No Longer Be Viable Investigation Tool

    Years back, while managing a geotech office, I was responsible for a number of eng's and tech's doing pits. The rule is common sense - stay out if it is deep or liable to collapse. If sufficient data cannot be obtained then we would recommend borings to supplement the pits (although that would...

    bearing capacity for fill over muskeg

    Well Gwkwong the bearing capacities mentioned by others verify that you would have no problem and I think you are o.k. IF: 1 The muskeg/fill combination can support a decent dozer and loaded trucks. 2 The clay fill is good - not soft can be placed, and it also supports the dozer OK. (If the...

    bearing capacity for fill over muskeg

    Gwkwong just wants to put a tank, no problems with settlements. Some geotextile, a few feet of fill using light equipment - the biggest concern is support for equipment, I should think. The actual weight of the tank and footprint was not mentioned, but it would be nice to comment on that...

    residential foundations in peat

    Hi 3of12 (Civil/Environme) You say you want to support single family home foundations. If you are doing a sub-division, you have to consider services, etc. Just to get on the peat is a consideration. You must start with perhaps geofabric using light machinery. I would not even consider...

    Actual frost depths

    Hi Pbonarrigo: Finding a map of the "average" frost depths should give you a fundamental idea of frost penetration which can vary with: 1: Nature of the soil - is it fine grained or granular is is satuated or dry above the water table? Is there groundwater flow - sometimes the...

    Pile Seating

    One way I have overcome the potential problem of pile "kick-out" from an underlying sloping bedrock was to use a well drill rig. This can be a cheap option where you can socket into the rock. The other way is to use pile shoes or pins to "bite" the rock; that is, if the...
