What Is Drainage Tile, And What Are The Benefits Of Including It In Your Parking Lot Design?

If you're considering getting your parking lot redone or having a new one installed, one feature that your paving team may recommend is drainage tile. Understanding what this feature is and what benefits it offers when used in a parking lot design will help you make a more informed decision as to whether or not it is the best choice for you.

What is drainage tile?

Drainage tile is precisely what it sounds like. It is tile, typically made from metal when it is used in parking lot design, that has holes in it that allow water to pass through from above the tile to below it. There are several different ways drainage tile can be integrated into a parking lot. Often, it is placed along the edges of a lot and the lot is banked so that water runs towards the tile, and then drains through it into underground reservoirs. In larger parking lots, sections of drainage tile are often included centrally throughout the lot so water does not have to drain as far.

When is drainage tile needed?

Drainage tile prevents water from pooling, and is thus most important in areas where there is significant rainfall or snow. If you live in a very dry climate, drainage tile may be optional.

It is most important in larger parking lots, since the large amount of water that runs off them would often flood the surrounding land if the parking lot were simply banked to encourage the water to run off the edges. In smaller lots (think the type with three or four parking spots in front of a small store), drainage tile is not always as essential. The small amount of water that runs off these lots can sometimes be directed to storm drains simply by banking the lot properly.

What issues does drainage tile prevent?

In addition to keeping large puddles from forming in your parking lot (which would certainly be frustrating to customers), including drain tile in your design ensures your parking lot lasts longer. Allowing water to pool on the surface of the lot weakens it, making it more prone to cracks and potholes. Also, drain tile prevents slip and fall accidents in the winter when any water that stays on the lot may freeze and become slippery.

If your parking lot designer recommends drain tile, it is wise to take them up on the offer to include this feature in the lot. However, if you have a very small lot and live in a dry environment, you should talk to your contractor about whether or not the drain tile is absolutely necessary.
