Re: Basement Wall Leak

If I read this right you plan to use the hydraulic cement to fix it.

Tom Silva did this on an episode of Ask This Old House. Here's a link to the video and printed instructions.

Hector ... that may do the trick.
Just remember that hydraulic cement will set up quickly ... around 5 minutes ... so be prepared and mix only what you can use in that time.

Good luck.:)

Re: Basement Wall Leak

that video was to patch around a sanitary main, not a water main and not copper. do not do what you proposed and others have endorsed.

patching the hole is done with a flexible waterproof material, such as caulking compounds bitumen, black roof patch cement compound, ductseal, etc. like a gasket. these materials allow the pipe to expand and contract in temperature swings, yet prevent ground water from entering the basement.

you first need to determine if you have seepage from the pipe itself or from the soil on the other side of the foundation and be sure it is from groundwater or rainfall and not a leak from your water main (at the foundation wall or outside underground).

cement or hydraulic cement in direct contact with the copper which is also exposed to air and moisture on the basement side will likely corrode you need a gasketed airtight and water tight seal wherever air (oxygen) is present.

This sure has a familiar tone.

If it is such a bad idea then the existing copper pipe in the concrete foundation will be in jepordy. So according to you , what should be done to that pipe in contact with the concrete foundation ?

she thinks she is being sneaky and everyone won't notice that it is her. I don't know what word you were looking for but several come to my mind. some of them rather discriptive

That's what I was wondering, I have copper pipes in my concrete slab.

Re: Basement Wall Leak

:o I have similar problem in my house. There is moisture on the wall where the water main enters thru the wall. Somebody raised a question: is it ground water or a pipe leaking? Good question, but how to find out if pipe is at least 4 feet deep in the ground and has a porch concrete slab sitting on a top of it. I figured that if it was a bad leakadge in the pipe, water would be showing up at much higher rate than just few drops. It is under pressure in the pipe, right? If this is a case, Home Depot and Lowes has a waterprofing stuff that hardens even under water. You all think I can use it?
