i have a crack in the basement wall and water leaks everythime it rains.How do I repair the crack?

Answer 1

The proper technique is to get yourself a set of masonry bits,and drill out several holes in line of one another.Then you backfill the holes with lag plugs.Add sealant to the lags before putting them into the holes.This will strengthen the crack,and then all you have to do is fill the cracks with water rpoof mortar,and let it dry.This will reinforce the cracked areas,and seal the leaks.If you are unsure of how to do it still,call in a company that does basement leak repairs,and have them estimate doing it for you.It should cost no more than 13-1500.00 at most.If they charge too much more,you are being taken!Good luck!I would call in a handyman if other companies charge too much.You also need to dig around the foundation where the leak is from the inside,and patch the crack from the outside.Be sure to put a vapor barrier on the outside,to seal the crack after patching with a heavy mortar patch.Then put gravel in for your backfill outsideLastly,deflect water from running straight down to the ground by raising the pitch of your gutter,and putting a splash block under the gutter downspout to avoid it from filling up along your foundation.

Answer 2

There is no easy way to do this if the basement is below ground.You will have to know the approximate area of the crack,then dig below the beginning of the crack.After this is finished if it is a block wall and the joints are the problem you will have to re point,meaning grind or chisel the old cement out and put new in.This can be done with a premix you can purchase at most hardware stores along w/the tools that it requires.To be on the safe side you could apply waterproofing cement over this w/a membrane over the actual crack applied w/a thicker water proofing cement.On the other hand,if this is a concrete wall,clean out any loose particle and use a silicone caulk with a 50 year warranty to fill crack with. Good luck.

To stop the leak in the short term buy a bag of hydraulic cement. This is sometimes called instant water cement. It's a concrete that sets very fast and will actually expand inside the crack sealing it. Follow the directions on the bag and remember to mix it right where you'll be using it as this hardens in 5 minutes or less. Using a trowel press it into the crack starting from the bottom of the crack and working up. This will seal it for the short term but you'll still need to dig out the outside of the wall and fill and seal the outside of the crack for a long term repair.

I had a similar problem. UGL Waterlock is quite good at stopping seepage through the walls, but won't really stop leaks through a crack. For that I used hydraulic cement first. It is used in swimming pools, because it expands as it cures and helps block the leakage paths. This combination was effective, but not the complete solution. The best fix is to not let the water enter in the first place. You will need to improve the surface drainage, so rain water drains away from the foundation. If possible, it is also a good idea to repair or replace any damaged footer drains and the water proofing on the exterior of the walls as well.

Good luck

Answer 5

Well you want to get a water resistant filler, i know we had to fill in a crack in our pool and the stuff worked great. You also may want to look into the possibility of the crack being structural. Check and make sure the crack doesn't just continue to open. If something shifts after you cover it up you could be dealing with a bigger problem. Maybe its worth it to have someone come take a look. Even if under the guise of an estimate.

Answer 6

you will have to parge the wall with concrete by this i mean a thin layer must be put on the wall all though the best way is to dig down around the foundation which may require a backhoe put some gravel down run a drain pipe away from the house and once again put a layer of concrete on the wall from the outside then a good coat of tar or the likes of another words there is no easy way out you may come up with a quick fix but that's what it is a quick fix that wont last

Answer 7

dig down to find the crack
take a wire brush and clean out the crack refill the crack with concrete it dry
now if it is a small crack use a tar based filler or compound but only if is small
good luck

Answer 8

Grind or chip it out so its deeper then use a leak stopping cement and then paint with UGL use the oil base not the water base .The water base doesn't hold up

Answer 9

There are several water seals made specifically for this purpose. Go to your town's hardware store, Home Depot or Lowe's and ask.
