How to Install a Sand Trap Drain

If a character does not have the proper drainage system the consequence can be harsh flooding of the yard, basement, and already the garage. Because soil particles come in a variety of sizes, soil permeability can vary. for example, soils with small particles are called cohesionless soils. in addition, there is soil with large particles such as gravel and sand. If you have problems with flooding of your basement or garage, you may need a specific kind of drain called a sand trap drain.

Structures built on cohesionless soils can ultimately undergo harsh structural damage from flooding which will consequence in a costly repair job. These drains are designed for soils with low permeability. Permeability is the character of the soil hole system that allows water to flow. When it comes to permeability, the general rule of thumb is the smaller the particle size, the lower the permeability of the soils. A sand drain is a hole drilled in a cohesive soil and filled with sand. Because the sand has bigger particles, its permeability is much higher; consequently water will flow by it much more easily allowing it to drain properly.

The following is a general guide on how to install a sand trap drain:

1. When installing this drain, the height of the concrete foundation above the floor should be about 5- 6 inches. It is important to make sure you have adequate height above the floor before you begin the project.

2. Once you have the accurate height measurements, at the identify where you are installing the drain, make a line with a pencil around the areas perimeter. Use a utility knife to cut by the lines on the drywall. Once you have cut by take out the pieces at the bottom.

3. The bottom of the drywall needs to be replaced with plywood. About 2 or 3 inches of the drywall should sufficient. Install the plywood. Any drain pipes will have to be secured above the drain pipe that will be going into the side of the sand trap. in addition, the pipe going into the sand trap should be secured a minimum of six inches above the bottom of the trap. An elbow piece has to be attached to the sand trap drain in order to help transport the water by the drain system and carry the water away from the area that is inclined to flooding. Remember, a 2-inch vent is required for the sand trap.

4. Install the sand trap drain and construct troughs that are about 4 to 6 inches wide on each side that slant into the trap.

Extensive rain and melting snow can cause excessive water to build up if you do not have proper drainage. If you are a homeowner with excess water accumulation, a sand trap drain may be the solution. If the sand trap drain is for the garage, a metal grate secured over the drain will permit people to walk or excursion over the trap without causing damage. Many experts recommend building a custom sand trap drain; however you can buy them as pre-made sand trap drains.
