Trench drains are typically used in areas with high amounts of water runoff such as patios, driveways, and walkways. Concrete trench drains are a great way to improve your home drainage system and protect against flooding.

13 Step-by-step Guidelines on How to Install Trench Drain in Concrete
Step 1: Prepare the Area
First, you will need to prepare the area where your trench drain will be installed. Start by clearing out any debris and loose materials that may obstruct the flow of water.

Make sure all edges are clean and free of dirt or anything that could create a blockage. If necessary, you can use a shovel to dig out any extra space that may be needed.
Step 2: Mark the Drain Location
Next, mark the location of your drain on the concrete with a marker or pen. This will help guide you as you cut and shape the trench at a later step. If possible, try to draw an outline of the entire shape you want your drain to be. It’s a good idea to draw it slightly larger than you need it so that it will fit snugly when installed.
Step 3: Cut the Concrete
Once you have marked off where your trench will be, it’s time to cut into the concrete. Use a circular saw with a diamond blade attached to make straight and precise cuts along the edges of your outline. Be sure to wear safety goggles during this process and keep an eye out for any wires or pipes that may be hidden underneath the surface.
Step 4: Create Anchor Bolt Holes
Using a hammer drill, create holes along the edge of your trench for anchor bolts. Make sure these are evenly spaced and large enough for bolt heads to fit in easily later on.
It’s best to use a drill bit slightly larger than the size of your bolts for the best fit. Otherwise, your trench may be too loose and could lead to flooding.
Step 5: Install Anchor Bolts
Now that you have your anchor bolt holes ready, it’s time to install the bolts. Using a hammer, drive the anchor bolts into place until they are securely secured in the concrete.

If you’re using the right size, they should fit snugly and won’t move around when stepped on. But if they’re too loose, you may need to add more bolts or use a larger bolt.
Step 6: Place Trench Drain System
Take your pre-made trench drain system and slide it into place along the edge of your trench. Make sure everything is level and aligned correctly before moving on to the next step. If necessary, use a leveler to double check your work. Because these systems are pre-made, they should fit perfectly into your trench without any extra work.
Step 7: Secure Trench Drain System with Mortar Mix
Mix together mortar according to package instructions and begin spreading it evenly over the surface of your trench drain system. This will help secure it in place and make sure no water can seep out from underneath. After the mortar has dried, your trench drain should be securely in place and ready for use.
Step 8: Install Drain Cover
Place the drain cover over the top of your trench drain and use mortar mix to secure it in place. This will also help keep any debris and pests from entering through the drain system. It’s important to make sure this cover is properly sealed in order to keep your system working efficiently.
Step 9: Backfill Your Trench
Using a shovel, begin to backfill the trench with soil or gravel around the edges of your trench drain and cover up any remaining mortar mix. Make sure everything is level and fill in any extra space that may be needed. If necessary, use a tamper or other tool to pack down the soil and get it ready for use.
Step 10: Connect Drain Pipe(s)
Attach a connecting pipe to one end of your trench drain. This will allow for water to flow into your new drainage system instead of pooling near your foundation or elsewhere on your property. If you need to, use extra connectors and pieces of piping to make sure everything is connected correctly.
Step 11: Add Gravel and Soil Cover
Once your connecting pipe is securely in place, add some gravel around it to help keep soil from entering the pipe. Then, cover up any remaining parts of your trench with soil or other suitable material.

Then, you will be ready to enjoy the benefits of your newly installed trench drain system. It should help keep water away from your home and other areas of your property with ease.
Step 12: Test for Leaks
Now that you have installed your trench drain system, it’s time to test for leaks. Start by turning on a hose near the drain and make sure no water is spilling out anywhere.
If there are any leaks, make sure to seal them up as soon as possible in order to keep your system working properly. It’s also a good idea to check your system every few months just to make sure everything is still in working order.
Step 13: Clean Up Excess Material
Once you’re finished testing for leaks, clean up any excess materials that may be lying around the area. This includes mortar mix, gravel and soil. That way, your property will remain neat and tidy and you won’t have to worry about any potential hazards. After you have cleaned up, your installation is now complete!
