Concrete gravel boards are a great way to protect your driveway or patio from cracks and holes. They can be installed over concrete, tar, asphalt, decomposed granite, brick pavers, or other surfaces that would benefit from extra protection.
These boards are often used in commercial applications like parking lots or around pools. However, many people wonder if it is possible to drill into them for drainage purposes.
The answer is yes! With the right tools and techniques, you should have no problem drilling through these materials without damaging the board itself, making your job much easier.
How Can You Drill Concrete Gravel Boards?
We prepared easy-to-follow steps on how to drill concrete gravel boards. You can use the following steps to help guide you through this process:
Step One: Mark the Locations
The first thing you want to do is mark the location where you will be drilling. You should create a small divot to help guide your drill bit. This will ensure that your holes are drilled in exactly the right place, and it can make things easier for yourself as well.
The best way to go about doing this is using a marker, but if you do not have one available to you, there are other options. You can simply push the edge of a screwdriver into the concrete so that it creates an indentation for your drill bit.
Step Two: Create the Holes
Once you have your divots in place, it is time to actually drill. You want to make sure that you use a masonry bit so that the screw will be able to grab onto something when inserted into the hole properly.
If not, there is a good chance that your screws will fall through, and they will just spin around the inside of your concrete gravel boards.
Step Three: Inserting Your Screws
After you have created your holes, it is time to put in the screws themselves. Make sure that when placing them into their respective divots that they are not flush with the surface of the board.
This will make them easier to screw in, but it is also important for safety reasons. If the head of your screws is flush with the surface of your gravel boards and someone trips on top of them they could be injured as a result.
Step Four: Finishing Up
After you have put all of your screws into the place, you should fill them with concrete. Do this by first pouring some of the dry mixtures into a bucket and slowly adding water.
You want to make sure that you stir your mixture thoroughly to evenly distribute everything throughout the mix. Otherwise, there may be pockets where no cement was added, and they will not be as strong as others.
After filling them with concrete, make sure that they are entirely flat when they dry. If there is a raised region in the middle of your gravel boards, even if it’s just an inch high, this can cause issues with installation and prevent water from draining properly, which could result in some damage to surrounding areas.
Make sure that all edges are flush so that everything looks nice and neat before installing your new concrete gravel boards!
