If your home is located on a hill, you may have struggled with finding the right type of driveway. Building a driveway on a steep incline presents a number of challenges — rainwater will drain quickly towards the base of the driveway and vehicles exiting the driveway become difficult to control if the surface has poor traction. Unfortunately, not all materials are suitable for steep driveways. Which material is the best choice for building a safe driveway on a steep incline?
While gravel is often a great choice for driveways, it's unsuitable for driveways with a steep slope. While gravel driveways are compacted into the soil by a presser, there's nothing that adheres the bits of gravel together — vehicles driving on your driveway will slowly loosen the gravel, where gravity will cause it to roll downhill and build up on the base of your driveway. Maintenance is often an expensive nuisance, as you'll need to continually add more gravel to the driveway and compact it.
Concrete pavers are another poor choice for a steep driveway. Pavers are permeable — the small gaps between the paving stones allow water to pass through the driveway and enter the gravel base underneath. On a steep incline, all of this water will begin to rush downwards towards the base of the driveway, which quickly causes the gravel underneath the pavers to shift and erode. When the gravel base underneath the pavers erodes away, your pavers will begin to pop out of place — you'll spend substantial time and money periodically replacing and seating your pavers, making them a poor choice for a steep driveway.
Concrete is a durable, long-lasting choice that's suitable for a steep driveway. However, it does suffer from a glaring issue — concrete becomes very slippery when it's wet or when it snows. Additionally, stamped concrete won't solve this issue. Ice, snow and dirt can build up in the grooves created from the stamping process and render a stamped concrete driveway as slippery as a smooth one. When you're driving on a steep incline, a driveway with poor traction is a major safety issue — it can be difficult to control your speed when you're driving down the driveway. If your breaks fail while going down your driveway, you may accidentally enter into the road at high speeds.
Asphalt is the best overall choice for a steep driveway. Asphalt provides better traction in rainy or snowy weather conditions than concrete, and it's an impermeable surface that isn't prone to wearing away like gravel or concrete pavers. It's also very easy to install on a steep incline — concrete trucks are very heavy and have difficulty backing up slopes, so installing a concrete driveway on a sloped surface can be a very difficult process.
If your home is on a hill and you need to build a driveway on a steep incline, asphalt is the ideal choice. It's a less expensive option than concrete that retains its traction better in the ice and snow. Contact an asphalt paving contractor by looking online like sites like http://www.phend-brown.com and provide them with the dimensions of your current driveway along with its grade of incline for a cost estimate.Share
