You've seen it many times I'm sure, a slab poured next to the house which wasn't supported on the foundation wall or pinned on the house side of the slab-the soil settles and the slab tilts in toward the house.

I'm looking at fixing one on a 16yr old home which has settled almost 2" next to the house (covered porch over), 0" on the furthest part of the slab since it was built on a proper foundation stem wall. The slab looks as if it were poured against the plywood rim joist, which is showing signs of rot.

Has anyone installed a new 'cap' on a situation such as this?

Hey Chevy,

I found a mechanic to change my tdi timing belt for $250. He is a dealership mechanic and I'm going with a 100,000 mile timing belt.

What do you mean by a "cap"? Do you mean just pouring over the existing sunk sidewalk?

What is width of the slab (sidewalk)?

Sounds like the water is draining towards the rim joist and this won't be good.

I would try to talk them into simply removing the slab. I don't believe in pouring concrete next to a foundation.

If it must remain, I guess you could remove it and replace it for $5/square foot. Any chance to keep it out 2' from the foundation and put some plantings in there? It would be a good idea to keep it away from where the excavated area was.

it's about 6' wide, it's a covered porch intregral to the house design that leads to the front door. There is a Quickcrete product for going overtop concrete-only good to I think 1-2". That and a bonding agent, thought may be an appropriate low budget fix.

great price on the belt. I was driving the TDI today-nice and peppy and the mileage aint bad either :) Mine has 303k on the clock!

My Father-In-Law had a back sagging set of 5 steps. the very front is a step on top of the sidewalk and the back settled about 4" I crawled in behind it dug a trench in the middle to stand a 6 ton bottle jack on a 4x6 and jacked it up 5" and with a 2x4 shoved dirt underneath packing it as much as possible and let the jack back down and told him he was good for the next 5 to 10 years!.

He was Happy, I was Happy it was a Happy Day!

Cool!
Does anyone here do MudJacking?

I'm curious about how much pressure is going through the grout hose since they are simply holding it down with their knee.

Grout jacking is well and good,
but it begs the question.....
What about this?
