How Do You Fill A Void In A Concrete Wall?
There’s something about concrete that makes it seem impenetrable. But if you have a hole in your concrete, it can become a major problem. Not only can the hole cause your concrete to buckle and crack, but it can also lead to water damage and even structural failure.
A few options are available if you need to fill a void in a concrete slab. One option is to use a sand-cement slurry called “mud.”
This mixture of sand, cement, and water is pumped through holes drilled in a slab foundation to fill voids underneath. While this type of slab jacking can be cost-effective, there are some potential drawbacks to this type of repair.
One potential downside is that mud can be difficult to clean up. Additionally, if the void is located near a water line, water intrusion could be a problem. Another potential problem is that a heavy layer of mud can make the slab unstable.
If you’re considering using mud to fill a void in your concrete slab, be sure to consult with a professional. They’ll be able to provide you with a variety of options and advice that will help you select the best solution for your situation.
How Do You Seal A Pipe In A Concrete Wall?
When pipes run underground through concrete walls, groundwater can seep around the pipes and through the concrete.
Shifting earth or home movement can frequently create a space around the pipe and provide an escape route for water before it reaches the foundation drain pipe. Most repair products do not bind well with concrete, making it difficult to fill the gap firmly and fully, but hydraulic cement does.
Step 1
Locate the leaky pipe in the basement wall. Blot out any water that has leaked from the hole using a dry towel.
Postpone the project until the water stops flowing through the hole if there is a significant flow.
Step 2
Carefully remove portions of the surrounding wall near the pipe using a chisel or a drill fitted with a masonry bit. The aperture should be about a half-inch in diameter and three-quarters to one inch deep for proper repair.
Step 3
Using a moist sponge, remove any debris or dirt from the hole. A slight wetness will assist the repair substance to bind better.
Step 4
Press hydraulic cement into the hole with a tiny trowel or putty knife. Tightly pack the material in and ensure that the cement attaches to the pipe and the surrounding wall. If necessary, fill the gap with layers of cement to gradually build up the space.
Step 5
Because hydraulic cement hardens quickly, it works swiftly. Spread the material across the wall to strengthen the connection and conceal the repair work. Do not touch or change the pipe’s location until the cement has fully set, as directed by the manufacturer.
