We have installed 6 dry wells around the building as there was no empty space for drainage water.
We did this as per the engineer's advice.
- It's clay
- Water table 2 ( During rainy season ) to 4 feet ( During summer )
- Ground water is saline
I asked my engineer if it will impact ( Differential Settlement ) the building foundation he said it's not a problem as all the buildings in the town are standing in wet ground ( 5 feet ground water table ).
But I'm worried about the building foundation such as
- Capillary effect
- Hydrostatic pressure on walls
- Water seepage on the walls
- Differential settlement
What should I do ?
- Should I keep plants around the building wall and dry well ?
- What kind of Plant's root would not damage the wall ?
Here is the photo of sample retaining wall that builder has in mind. Any suggestions are welcome
Here is how the dry wells ( 5 feet depth ) are going to be connected sequentially
I'm happy with the whole but I'm worried about my building foundation like I mentioned earlier and I want to take all the steps to make sure my building is safe and sound.
Our house is built like in the below picture [ Framed structure not Load bearing wall structure ]
Please find the video of dry wells on the south side of the building here
Please find the video of dry wells on the north side of the building here
According to local engineers , I have nothing to worry about this whole cement ring well drainage set up , because ground water table level is already at 3 to 5 feet so every building in the town is practically standing at wet ground so this drainage well will not do any harm. But I'm not convinced this dry well can saturate the soil bit more and could cause settlement which can lead to fraction in the wall ?
Somebody please give their wisdom in this.
