A question from a friend of mine. His house was built around 30 years back. The area has seen lot of develoopment during this time and now his ground floor level is below road level. Olinth beam has also gone under the road level. This has led to permanent dampness of gf walls, which i believe is a risk to structure. Wondering if there is a solution to fix this?

Check solutions to lift house using hydraulic jack and raising the plinth. House is lifted using multiple hydraulic jacks slowly and placed on raised foundation, You can find many such videos in YouTube India with contact numbers of contractors.

I rememer As per one such link a house in Gurgaon was lifted for 6L seeing it may be a rosy picture and location is different budget should be higher I guess .

good to hear from you after a long time. Hopefully you are soon going to be planning for moving in.

He did explore lifting up. However there are houses with a gap of not more than 5 feet on 3 sides of his house. So lifting was ruled out. Was wondering if there is way to replace wall at the GF level with concrete in steps. Say break 4 feet of wall and put concrete there. Let it cure and then move to do the same with next 4 feet.

Why not remove mud around the foundation and do water proofing ? I am no expert, just asking.

I believe foundation has become weak due to all the dampness. So they are concerned that the building may fall if they play with foundation.
