derwall

thanks for the info cheers

the foundations don't go as far down in the crawlspace to ground level unfortunately, they are about 3 foot above ground level. thanks, there is a brick pile or tower fundation also in the center of the crawlspace, the SE going o look at a design to replace this with a heavy steel post. I'm hoping if i don't dig to close to the wall foundations i can avoid underpinning and then concrete over the soil clay that remains around the room and back to walls. thanks

thanks for the information very helpfull,, does finding this water about 2 foot below my intended new concrete slab floor mean i cannot now plan to dig down and lay a slab in the basement at ground level. if so glad i dug the plot hole down that far. thanks

i dug a trail hole down to about a foot below the ground level, it's 2meters away from any foundations and about 10 x 12 inches wide. There was no signs of water as i dug the hole (even as i was leveling out the the very bottom of the hole. I was surprised the next day to see about 2 inches of very clear water in the hole. ( not muddy at all, and the water never came from above). yes looking forward to hearing what the SE says about our plans, i know hiring professionals is a must with this type of protect. thanks.

hi i have a lower ground level at my home, half is a fullsize basement kitchen the other half is a crawlspace, 4ft plus clearance. i want to dig down another 3.5 foot but without going so close to the foundations that i need to underpin. i have heavy clay soil and was thinking i could go down 3.5 t foot as long as i was 2 foot away from the foundations and then cover the clay with concrete back to the wall and lay a new floor slab. I have an appointment with a structural engineer tomorrow, but was wondering if anyone on here has done this too. Thank you

Hi, im not skilled in any building trades, but like to have a go at diy projects around my house. the lower ground level to our home is divided in two halfs, one half is a full size basement kitchen, the other half of the lower ground floor is a crawlspace. my project is to turn the crawlspace into a basement area but i dont want to dig so close to the foundations that i have to underpin half the house. I have structural engineer comming for a site vist tomorrow and to talk about my plans. Im planning to post in one of the forums to ask if anyone has dome anything similar. My soil is heavy clay. (this will be the largest project ive tackled so far). Thank you
