They’re also helpful for washing things inside the garage or cleaning up after minor leaks and spills. A garage floor drain can prevent water from soaking into your concrete or running onto your driveway. When the concrete floor is pitched into a drain, all of the water flows into it and away from your home’s foundation.

Installation of garage drain

1: Locate Your Drain Line

When you’re ready to install a new drain line, start by locating where you want to put it in your garage. Make sure that there isn’t already one on the ground and measure it out (length, width, and depth).

2: Install a Drain Line

Install a PVC drain line by pouring concrete around the pipe. For added protection, run a bead of caulk around the bottom of the access cover before positioning it into place on top of your new drain line. Ensure that there’s an excess pool of water before covering the opening with sand or soil for drainage purposes.

3: Prepare Your Site

Prepare your site where you’re planning to install your drain standpipe by digging out about three inches around it (this will give you enough room for rainwater) and then adding gravel below grade for better drainage. After placing larger rocks at the base, fill the hole with soil, making sure to tamp it down as you go.

4: Cover the Drain

Cover your newly installed drain with a piece of metal or concrete. Use a level to ensure that it’s even before attaching it permanently in place.

5: Finish Up

Finish up by attaching your drain hose and testing for proper drainage. Once everything is in order, reattach the door to your garage. Now you can safely wash your car or motorcycles on the garage floor without worrying about water damage!

Types Of Garage Drains

Garage floor drains are used to collect water from the garage floor. The drain is simply a hole in your garage floor with an attached pipe that carries the water away. There are two main types of drain systems – perimeter or trench drains, and slab (or “French”) /Sump style drains.

Perimeter Drain System

A perimeter drain system works well for most garages. A perimeter drain system consists of perforated underground piping installed at the edge of a concrete slab underneath a layer of sand which functions as a filter.

Perimeter drains should always be located on the exterior side of any wall or divider within your garage so that all water flows towards its center—the focus being downspout(s). The downspouts will discharge the water away from your garage and foundation.

Trench Drain System

A trench drain system is designed for areas where the surface water drainage is poor or for higher driveways than the garage. A trench drain system consists of trenches filled with gravel, which collect and carry the water away.

Slab / French Drain Style

A slab or French drain style is a more sophisticated drainage system that can be used in place of or in addition to a perimeter drain system. This system collects water through drilled holes in the concrete slab and funnels it into a sump basin where it is pumped out and away from the building.

The type of garage floor drain you choose will depend on the layout of your garage, the slope of the ground, and the severity of the water problem.

No matter what type of garage floor drain you choose, be sure to keep it clean and clear of debris so that it can function correctly. Be sure to regularly check your downspouts and gutters to ensure they are doing their job and directing the water away from your home.
