    deep crawlspace in SC home below water table

    Thank you all for the input. I am still awaiting a visit from the geotechnical. He has rescheduled on me twice. In the meantime, I have had a structural engineer take a look. He advised the same as many of you though he did ask a few questions in which my answers seemed to help with. A little...

    deep crawlspace in SC home below water table

    Terratek: there is a storm shelter type door on the back for access with a ladder. I was going to use a cement chute to dump in the fill sand along with a wheelbarrow. I haven't thought through compacting yet, but if sand were used as fill would it need much compacting? Sand was my thought for...

    deep crawlspace in SC home below water table

    SlideRuleEra: Interesting how you would run the poly. I have had many people tell me when I put down the poly to cover the entire crawlspace floor, but they also weren't mentioning installing a blower in the crawlspace. I have a call in to a Geotech. I will see what he has to say and report...

    deep crawlspace in SC home below water table

    oldestguy: Thanks for the tips/info regarding the drain system. I will give you the backstory which may help. We had a significant amount of rain back on Oct 3 & 4 here and collapsed the curtain wall on one side of this deep crawlspace from all the hydrostatic pressure on the outside of that...

    deep crawlspace in SC home below water table

    I had planned on removing the sump pump and reinstalling it with a new French drain inside the crawl space at the elevated crawl space floor. That way if there was ever water in the crawl it could still be pumped out, but the water would need to rise significantly higher before the pump would...

    deep crawlspace in SC home below water table

    @JAE Thanks for the reply. Should I direct this to a structural or geotechnical engineer? The 3 foot depth is consistent with the rest of the crawlspace and I would add vents to that section of the foundation. I will also remove the sump pump prior to filling. The load was something the...

    deep crawlspace in SC home below water table

    I have a portion of my crawlspace, 19'x12' that is dug out 7 feet below ground surface. It has a French drain system which runs to a sump pit. The sump pump runs every 2-5 minutes most of the year. I have spoken to a couple of engineers(one structural and one civil) who were unsure about the...
