Water leak / rec room


When it rains medium/heavy we gets small amount of water in one area where the wall meets the floor in our basement rec room which has drywall. The small backyard patio we have is slightly pitched towards the house. Mudjacking the patio slab is putting a bandaid on the problem, digging and regrading the dirt against the home is an expensive option or we can have someone do epoxy injection on the basement wall where the crack is which is also expensive.

What if we pour sand and add pavers on the patio and pitch all the water away from the home?

Mudjacking the slab would be a solution. I don't understand your "bandaid" characterization.

What happens to a cement slab after a few years when its mudjacked no matter what "filler" underneath is used? Stay in place or dip down back to where it was over time?

What I am trying to figure out is if epoxy injection is better than mud jacking at this point. I truly do not know if there is a crack in the wall because the drywall is 2' away from the poured concrete basement wall. Water comes in where the wall meets the floor. Mud jacking will hopefully divert the water away, but let's say I mud jack it....and I still have the same problem....?

I'm thinking, the success of the injected material, whatever it is, will depend on the base it rests on.

Would you recommend mudjacking which would pitch the patio slab away from the house? If there truly is a crack on the basement wall behind the drywall would that just get left alone? I ask because if I can divert the water away the problem is solved.....until the patio slab dips back down.

What if we pour sand and add pavers on the patio and pitch all the water away from the home?

water will simply soak through the sand to concrete slab and run right back toward the house.

if you have the 3-4" for sand and pavers? why not just pour a cap onto slab pitching the water away?

a always, just my thoughts

good luck

Can you explain what you mean by a cap?

If you mean pouring concrete over the existing slab the issue would be cost.

I don't think adding additional weight to a compromised slab will help.
Will repitching the slab keep all the water out of the basement? I don't think so, but you can do an experiment to see what happens.
Are you in a snow zone?

yes, I mean pour concrete slab on top of existing slab. the cost of a few yards of concrete seems to me to be the least costly way to go! depending on size? it's a do it yourself project.

as always, just my thoughts.

good luck

Thanks. I'm just trying to figure out the best way to go. Maybe someone else has had a similar experience.

So that's a yes about the snow zone. Too bad. In a temperate zone, i'd try setting up a plastic sheet(s) with a pitch away from the house, keeping the rain off the patio and away from the house to see what happened.
This time of year, you'd need a fairly sturdy structure to place the plastic over.

I don't know if mudjacking is ok to do this time of the year. Milwaukee is supposed to get an inch of rain on Wed.
