PEinc,
Thank you. Apologize for the wording, I "meant" to not mess with placing drypack around a pvc pipe. No intention to leave it out. On the contrary, I wanted to maximize it's presence. By placing them in the pier, it adds the benefit of increased drainage behind the pier as you mentioned...
PEinc,
Much appreciated. I had not thought about adding weep holes. Great idea that makes a lot of sense. I'd rather stay away from disturbing the new pier footing soil. What are your thoughts on just adding 1" pvc to the say top 1/3 of the pier pour and not messing with the dry pack?
With the...
SlideRuleEra,
Thanks for taking the time to look at my post and respond. I'm certainly not a Geotechnical Engineer (I'm sure that was/is obvious). I have found this forum to be very helpful. My question about the lateral soil pressure is more for my curiosity as a Mechanical/Civil Engineer on...
Thanks Oldestguy. After sketching all those ideas out, the underpinning sure is the least complex. My hesitancy has been around digging the dirt out from under the wall, potential loose stones, and settling. That got me thinking about other viable solutions that would acted more like a bench...
I have an older home that requires an internal french drain in the basement around the perimeter to provide drainage. The walls are field stone ~ 7 feet tall that are parged on the inside. The base of the walls is ~ 3 inches from the top of the floor. So my concern with the french drain is...
I see. So if you leave the earth side boards and cleats, do you just attach another face cleat to the previously embedded cleat when you come to the final piers between cured poured piers? Thanks.
PEinc,
Thank you so much for the extra photos and wisdom. This helps considerably. Looking at this and your presentation, I'm wondering what type of wood you are using. Would standard untreated pine suffice or do I need something else as a minimum? Also, since I won't have access to the exterior...
PEinc,
Great information. Can you provide any further details on the "shelf" material, construction, and placement during the digout? The wall stones appear to be generally 1 ft in length and 6" to 9" into the wall and they are around 4" thick. Would you still recommend drypack with such large...
Hi PEinc - Really appreciate and respect your inputs. A couple things about the existing drain/situation...
1) Not sure how long it was installed prior to buying the home
2) Installed with very shallow pitch with not much stone - assuming they knew enough to limit amount of soil removed under...
Thanks for the replies. I got the drawing from a local Structural Engineer. I would like to get ideas/advise here to discuss these aspects before proceeding with the job. I've attached some sketches. The first is the drawing for my house from the structural engineer (disregard my chicken scratch...
Hello,
I live in a 1950's single family brick cape cod home (30' x 30') just outside Philadelphia. We have always dealt with a wet basement and in particular mud/clay and silt coming in at the basement floor to wall joints. The basement height and height to ground are both 7 feet. The basement...
