Hey guys, so I just had the drain line replaced and now I need to patch up this wall. Any advice on how to go about it for someone new to this? Thanks a bunch!
They have a cement patch kit available.
I suggest hiring a professional to avoid causing a major issue if you’re unsure of what to do.
However, if you’re set on doing it yourself, I would recommend breaking it down below the hole and starting from the ground up with blocks, then adding a scratch coat and painting it.
To fix the wall, attach plywood and seal the edges with tape. Create a funnel using angled plywood at the top, apply bonding agent to the old surface, mix and pour Sika 262 (vertical patch) while gently tapping the plywood to distribute evenly and remove air bubbles. After 24 hours, remove the plywood and touch up any areas, especially the top. Allow it to cure before painting with suitable cement paint.
It’s best to seek help from a professional. Those cinder blocks look beyond repair 😳
Wrap some foam expansion joint around the pipes before pouring anything in there (you could even use foam cans if needed). Rapidset cement all is a good option to fill the gap once it’s formed. If you’re skilled with a trowel, you might not even need to pour anything – just make sure to use stucco mesh to cover the gaps across the pipes. You can trowel in rapidset mortar mix or apply it as a finish coat (after pouring), then use a sponge to create a stucco-like finish.
Square off the edges and use ‘soap’ on the pavers. Begin by separating the pipes from touching the mortar mix that will be packed into the gaps. Fill the voids so that the flat pieces you are inserting make contact with each other. Smooth out the flat surface. There are plenty of helpful videos available for guidance on this repair. While this may be more challenging for a beginner, it is definitely achievable, especially if you have experience with tile and grout work. Best of luck!
Add more rocks.
Apply spray foam and stucco patch.
If it were me, I’d hire a professional to deal with anything load-bearing on an exterior wall.
I’m not a plumber, but I wouldn’t risk putting something heavy near the pipe, even if it’s 10 years away. If it’s close to the outside, I’d be concerned about freezing, but drains do hold water so maybe it’s not a problem.
Oh wow!
I really hope this is just a prank.
I personally believe plumbing should not run through an exterior wall! Inspection failed!
Enjoys the warm weather, which is great.
Have a plumber relocate that line to the inside.
I know this may not be the news you were hoping for, but those cinder blocks were essential for supporting everything above, including the window and roof. Without them, there’s nothing to bear the weight from above. Eventually, the weight will cause sagging and affect the operation of your window. It’s crucial to rebuild and reinforce that section of the wall around the pipe to prevent future issues. Seeking professional advice is the best way to move forward. Simply patching the hole with mortar won’t solve the problem.
Put a bush in front of it and give a shout to a real estate agent.
It looks like the cinder block under the window is broken open. You’re pretty lucky because usually cinder blocks need support before breaking like that.
It would have been better if they had replaced the entire waste arm
Offers an inexpensive home warranty, but they lack customer care.
Can you toss a few broken cinder blocks inside?
Wow, that’s incredible!
I’d suggest using a cement blade on a grinder to make it square, possibly adding a 2×10 board and then applying stucco over it.
Try using some sturdy plywood and securely attach it to the foundation before filling it up with reet
