Now that you’ve met the water bars that are best suited for gravel driveways, let’s discuss one or two things that typically arise when water runs down the gravel driveway.

How to keep pea gravel from washing away

Pea gravel has a number of compelling benefits including being an inexpensive driveway option and being extremely easy to maintain.

But it has a few conspicuous drawbacks with most owners being concerned that it can easily be swept away by a deluge.

The good news is that you can avoid this problem by implementing a few basic measures depending on your topography.

The most foolproof way is probably installing a suitable drain along the edge of the driveway to redirect the water where it won’t wash away the pea gravels.

You could make a trench either down the center of the driveway or next to the edge.

Be sure to slope it properly so the water drains efficiently into the accessory.

How to fix a steep gravel driveway

Too steep a drive is dreadful news for property owners face as far as drainage is concerned.

Not only do you keep worrying that the sharp gradient might cause the driveway to be washed down the street but there’s also a likelihood of it bringing other home damaging problems.

If you’re in this predicament, your foremost solution is sloping your driveway such that all the excess water runs off towards a safe place such as a ditch.

In addition, as seen throughout the article, you may also solve many drainage challenges with the correct placement of driveway drains like water bars.

Of course, you should add a quality grate to the drain system to keep debris away.

The last thing you want is it to get clogged during flooding.

There are other quick-fixes including raking the gravel to make a way for the water to stream off the unwanted locations.

For the water bars to operate well, they have to be correctly installed and in the right place- poorly constructed water bars become an obstacle and blocks the flow of water off the driveway.

It’s also important that you regularly inspect them to be sure that it’s free of silt or other debris because rainwater can carry deposits which often build up choking the water bars.

That way, your water bars will be useful for long.
