Does your driveway sit on a fairly steep slope? Every time it rains, do you have water running down your driveway into the street? Even worse, does the driveway slope towards your house, driving water into your garage after every storm? All that running water can do serious damage to your driveway. It can cause cracks in the asphalt or concrete. This is especially true if there's a low point in the driveway where water tends to sit. Here are three common methods for handling driveway water runoff:
Install a catch basin. This is simply a hole that's cut into the driveway. The hole is covered with a removable grate. Water runs through the grate and into the basin. There should be a pipe inside the catch basin that directs water to the local drainage system.
A catch basin works best when the water tends to flow to one spot or if there's an area where water pools. If water runs all over your driveway, a catch basin may not catch all of it. A catch basin is one of the least expensive water management options.
Install a channel drain. A channel drain is much like a catch basin. The difference is that the channel drain is cut all the way across the driveway. It's a strip that's usually a few inches wide. It has a grate over the top and a drainage pipe inside. As water runs down your driveway, it hits the grate and is flushed away through the pipe.
A channel drain is a little bit more expensive and complex than a catch basin, so you'll likely need a professional to install it. One issue with a channel drain is that it can sometimes get clogged by rocks and pebbles.
Install permeable driveway pavers. This isn't just a water management solution, but rather an entirely new driveway surface. Permeable pavers are those that can absorb and drain water. They're usually made from brick, stone, or concrete. They're laid over a water-absorbent layer of material, like crushed stone. Rather than running down your driveway, rain water seeps into the cracks between the pavers. It's then absorbed into the crushed stone before it works its way into the surrounding soil. This is a great way to prevent any runoff. It can also be an effective irrigation system for surrounding landscaping.
