When you notice that it's time to get a new water well at your house, then there are things that you are going to need to do. One is to make sure that your old well is properly capped off. There are a lot of reasons why you should cap off an old, unused well. The biggest of which is safety. There are stories of children falling down into unused wells and being stuck. Many of those stories don't have good results, but a few, like Baby Jessica McClure, have had good turnouts. You want to make sure that any children who wander around on your property don't end up as one of their stories, and sealing up your well is the easiest way to do it. So, what do you need to do to seal up an old well?

Remove Any Equipment

Before anything happens, you need to make sure that you have taken out any equipment that may be in the well. That means taking out the pump, any pipes, or anything else. That will help the cap stick better and help to make sure that nothing contaminates the soil around the well. 

Research Fill Requirements

Different states require different kinds of fill to go into the well. Many of them require bentonite clay or a mix of bentonite and cement. Bentonite clay is a very fine clay that is formed from volcanic ash. If you are going to DIY the sealing, you should have no problem getting a hold of the amount of bentonite that you will need. 

Work From the Bottom Up

You can't just put something over the top and plan for it to render the well safe. Leaving the hole underneath, no matter how deep it is, will cause any kind of cap to eventually fail. If your state allows it, you can get some kind of fill that you can dump down into the well. For example, if you have a quarry in the area, you can ask if you can have or buy some of their leftovers and scraps to dump down your well. Then when they have put some down there, you can mix cement and bentonite together and start pouring it on top of the fill until you reach the top. You will have to leave time for cement layers to dry, so it may take a few days to completely cap off the well, so make sure you have restricted activity to the area while you are working. 

If you have an old well, it is your job to make sure that it is properly sealed off so no one can get hurt. For more information, reach out to companies like Wells Water Well Drilling & Repair.
