Diverting water isn’t anything new. Our ancestors have been diverting and controlling water’s flow for thousands of years – but it’s still important today. Imagine an asphalt driveway where the water can’t flow away from your home. You’ll have puddles, miniature streams in your driveway, and your asphalt will quickly deteriorate.
Luckily, we still know how to control the flow of water and much of that control on your asphalt comes from berms. Asphalt berms, also known as curbs, are small hills or curved walls of asphalt that establish a boundary to your asphalt and provide a direction for runoff, so rain and ice don’t accumulate all-around your property. An asphalt berm is normally 6 to 8 inches tall and normally shaped like a loaf of bread.
