    air in sidewalk

    dik; If you haven't got strength, air entrainment is all that works. A lot of old (50+ years) sidewalks in Gunnison, Colorado that never had sufficient air.

    air in sidewalk

    Colorado, desert & mountain areas - assuming 3/4" aggregate, moderate curing before hard freezes - I have never seen obvious freeze-thaw problems if the concrete strength is over 4500 psi, unless the concrete is fresh (recently placed, less than 45 days old) and has not 'dried' out, usually...

    High Snow Load on Deck

    My thought would be yes. I will add that my experience in Ski Areas is if woodburning fireplaces are allowed. Allow for a pile of firewood, even with the snow load.

    Retaining Wall Design Sanity Check

    1/2 inch movement in an 8 to 10 ft high wall is not out of the normal. The idea there will not be movement during and after backfill compaction behind this type of wall is not reasonable.

    Crushed Stone Footing For Residential Concrete Foundation Wall

    As one who deals with frost heave, as well as insulation issues, I ask: What are the shallow ground water issues? What are the site drainage conditions? Can shallow or deeper soil moisture continually migrate beneath the slabs or foundation elements and freeze? Will the "ledge below the soil"...

    Form release agent pooling in keyway

    Yes, if excessive quantities are present, it could be a detriment. My father, back in the 1960's, considered a wall base keyway to be an excellent collector of construction debris and such. He taught me to avoid them.

    Can someone help me better understand "mobilization" of deep foundation capacities?

    Driven Piling overcome both skin-friction and end bearing during the driving process. The driving process ends when the element has encountered sufficient bearing, side & end OR the depths are beyond the project budget. A drilled pier can be placed under a number of criteria for length but...

    Drylock on CMU basement walls

    Removal of the clay backfill area and replacement with a free-draining material (A57 stone is one such) would be my recommendation. After the wall has dried, the staining on the CMU can be 'washed' off, over a period of time. Assuming the staining in the basement corner is adjacent to an...
