Concrete dust in pool?

[langerking]

I am planning to remove portions of an 18 inch wall that is only 6 ft away from my pool. We will need to cut the wall in several places and I was wondering if the dust from cutting the block and stucco is very bad for my pool chemistry and filtration. I just got a new liner and fresh water in the pool and everything is wonderfully balanced. When the wall is subsequently being knocked down, there is of course the potential for debris to make its way into the water as well, so I have to be careful to not damage my new liner when removing building materials from the pool.

Is the dust a major concern, or will a thorough backwash and filter cleaning take care of it?

A pool cover would help a lot.

If you get dust in the pool, the filter should take care of it. The bigger problem is keeping the larger, sharper chunks on concrete from piercing the liner. You might trying buying one or more large tarps from Home Depot to cover the pool with. Just be sure to mark the boundary of the pool so people can safely walk around it.

If you are cutting the concrete, dust is your only concern, especially with a wet saw. If you take a sledge hammer to the wall, you will be surprised how far bits of concrete can travel. JoyfulNoise recommendation of a cover may be your best option to protect the new liner. Outside of this, I would shut down the main drain, pull from the skimmers and add skimmer socks to pick up all the debris & dust before it gets to the filter.

If you could take a picture of the pool and wall you are taking down, this would be great. If not, what exactly are the dimensions of the wall and is it all concrete or something else. Another idea is to place a 4'*8' piece of plywood ($25) in front of what you cutting, etc. Any piece of concrete will not go up, but outwards towards to the plywood, etc. Thanks!.

Tarps and some kind of 4 X 8 sheet goods are the ticket. Go cheap on the lumber; 3/8" OSB will work fine. Lay it against a couple of saw horses and seal the bottom with a run of duct tape if necessary. As already said, the debris with travel further than you think, so go big.

Thanks for all the tips, I was considering some type of barrier and the 4X8 sheets of OSB are a good idea.

I will be removing a little more than 21' of this 18 inch high wall (right up to the far left post in this picture) and we will replace with sliding sectional glass doors. Of course we will be replacing the posts with longer posts to support the trusses above.

Is it a cinder block wall or is it 100% filled with concrete? If it is a block wall, cutting at the joints could make your life easier.

 

[langerking]

I am not sure if the block is filled. I will need to drill a few holes and see. It's possible that the builder filled them, but I don't know why they would waste concrete that way. It is probably filled where the posts are.

 

[Catanzaro]

Sorry, I meant only a block coarse with a type of stucco coating. If so, then you can find the joint and easily break each one part without causing such a mess.

I wouldn't worry about dust, just large debris. If it were me, I'd set up some saw horses or anything tall around the perimeter of the pool and drape tarps or painters plastic over them to form a temporary barrier between your work zone and the pool water. I'd demo that wall out in the direction of the house, broom it up, shop vac the dust, and be done.
