Original Post: Foundation Repair Help

Sardis333 Member

Hello all,

I have a corner to my home that has a crack in the foundation. It looks like it is starting to tilt and sink. Trying to figure out the best way to repair this.

I have had two companies come out to give me estimates, all in the thousands of dollars range. My question is if I am able to do it myself or if I need a company to come in and do it.

I would like to bring the foundation back up again so it is level, then pour self-leveling concrete over to finish it up. But I don't know if raising the corner or just stopping the movement altogether is the right course of action. My main concern is having that corner sink further causing the beams holding the roof up to crack and fall down.

Any help in making the decision is much appreciated.

There is a problem with your footer. Either there is no footer or it was done improperly or over soft soil. So, I would say lifting the wood structure above and inserting a shim or pouring a leveling compound would only be temporary as the lack of support under the slab/footer still exists. You might have luck jacking up that corner of the building, removing the broken concrete corner, excavating to the hard virgin ground, then pouring a new footer in that area.

Or, a mud jacking company could do it relatively easy. Mud jacking will fill any void underneath that corner. If the problem is poor soil, quality mud jacking might displace the soft soil under the corner and provide the support needed for a permanent repair.

Original Post: Foundation Leaking into Basement

tick33183 Member

Hello,

I have a slow but steady infiltration of water at the interface of the slab and foundation wall. I applied hydraulic cement yesterday evening and I can now clearly see 7 or 8 fresh wet spots ranging in size from about 1 to 3 inches. The worst of it is in an area that originally had 4 to 5 steps and an entryway. The area has been blocked-in and the steps filled to grade on the exterior.

When I bought the home I installed a French drain, part of which runs past the former doorway at an elevation above the basement floor. I don’t have a good handle on when the interior leak began or if it was leaking at all before the drain. I’m beginning to wonder if the blocked in doorway is an issue to begin with and the drain going right by it is making it worse. Should I dig it up and install non-perforated pipe through that section?

Thanks in advance,

Tom

Sounds like a high water table. Usually, that is something that is known. I would start asking neighbors if they have the same issue.

Cement does not stop water. Waterproofing needs to be applied to the exterior perimeter of any below grade wall/footing in order for it to be waterproof. If no waterproofing was applied before it was backfilled, there's your problem.

I am located in South Seattle and would like to build a 40-inch high retaining wall. I will be using an 8 inch high by 17 inches wide and 12 inch deep decorative cinder block style blocks from Lowe's to complete the project. These blocks also have a lip at the back on the bottom for reinforcement. I will be placing a 3-foot tall chain link fence on top and filling the center holes with concrete at a 5-foot spacing. What kind of footer or foundation, if any, will I need?

You can never go wrong pouring some sort of footer, whether you use a stone base or concrete. Don't know much about landscape block, but regular block definitely needs a concrete footer below the frost line if you have that issue there.
