Will it work through cement block walls
1802662
It should, as long as there isn't any metal in the walls, like rebar. I can't try it, but I have a radio/radar background, and plain cement block doesn't interfere. In our house we have a set between the bedroom at one end and the kitchen at the other end, 50 feet away through several walls, and it works fine.

No it will not, you will need to put a virtual wall sensor in that area. You would have to move it yourself.

It will work, as long as you have a clear shot through a window or something (I broadcast hundreds of feet away without a problem). Trying to go through walls impedes it's abilities greatly. You only need one. By the way, the higher you have it, the better.

I have mine in the family room and it has to go through a brick wall that surrounds the patio as well. Once in awhile it does not go off. But other than that it works great. But it should work if its not to far from the transmitter.

Yes. Make sure when you are adjusting the sender and receiver that you are not standing in the path of the signal, or you will create such interference and signal deterioration that you may think the device is not working. It will go through walls and ceilings, but not through people.

yea! well, it should. Remember walls and trees and things cut the transmission strength every time they pass through it, but here's a good rule of thumb I use. measure the distance you need to transmit, then double it. if you're under the max strength of the device (i think its 1000 ft for this one) you're probably okay

I believe it does work thru walls and ceilings. We are very happy with the results....

Yes, the signal will go through walls. It does not have to be a line of sight. It needs fresh batteries often to keep it working all the time. I estimate I am putting in new AA batteries once every couple of months. David

My Hydro-Seal 75 worked perfect for the application I purchased it for. Sealing concrete block. I agree with Rick, For tile application over drywall, use cement backer board between the drywall and tileDan

I'm not sure. I haven't done it but in theory it should work. I do know the signal can't go through several walls.

Generally, I would say no, it will not work for concrete blocks. Having said that, if you are going to be drilling a few holes for example it may work. As an example, I want to mount a board to my basement wall. It would work for that. If you are going to be doing medium to heavy duty drill, you should get a hammer drill. There are several brands out there that would work, Bosch being one of them.Keep in mind that all the 12volt power tools have a couple of advantages. One is their size and the other is their weight. Although I have seen 12 tools in the tool boxes of tradesmen, they are for light duty use or where the above reasons come into play. Generally, I would say no, it will not work for concrete blocks.

it may work intermittently. I dont think it would be reliable. The walls will definitely cause problems at that distance.

I don't think this is powerful enough to use on concrete walls. This is a residential toolkit for minor household projects.

Hi,I am sorry to say, but this unit cannot penetrate through walls. this will make you, or anyone who is in the apt very sick.

I think so. I used it in AC wiring mode on concrete walls covered with plaster.

Yes it does. The transmitter's signal goes both through the outside wall and inside walls.
