What's The Best Material For Sloping Driveway?

best-material-for-sloping-driveway.jpg

Any driveway project will come up against challenges and one of the most challenging has to be a driveway that is on a significant slope. These steep driveways can be difficult to drive onto, to park on and especially to get the right material for good practical use. There are a few options for creating the very best and longest lasting sloping driveway, and some you want to avoid at all costs!

Some of the most beautiful houses are built into hillsides. These tend to have the most amazing views and therefore are often at a premium when it comes to price.

However, if you spend a lot of money on a beautiful hillside property, you will expect there to be somewhere to park your car.

The creation of a driveway that is suitable for the site is likely to mean it will be steeper than average and therefore a trickier project for your contractor.

Key Consideration No.1: Drainage

Choosing the right material is incredibly important when it comes to the longevity and good looks of your driveway and of course, the safety of using it. Water drainage is probably the most important factor as run-off of water down the slope can be a huge issue and will affect the driveway condition.

It is important that the sub-base is well drained and that water is directed as best as possible towards the sides of the driveway and away from the centre. The water should then be channelled towards a drain if possible.

If this is not done and water is allowed to pool anywhere or run excessively along the length of the driveway it could freeze causing safety issues or it may cause subsidence and lead to instability of the surface.

The result is a driveway that is steadily slipping down the slope.

One of the main reasons you are improving your current driveway or adding a new one is to improve how your property looks. By adding the right surface, those looks will be maintained

Key Consideration No.2: Safety

The chosen material needs to provide more than the average amount of traction for your car. The steeper the driveway the more traction and grip that will be needed.

You may also want to provide a parking area that is slightly more level than the driveway itself. This can be done by digging out a parking spot or turning area. There are number of materials that will add grip to the surface of your driveway and these will be discussed later.

Key Consideration No.3: Good Looks

One of the main reasons you are improving your current driveway or adding a new one is to improve how your property looks. By adding the right surface, those looks will be maintained.

A surface that quickly starts to slip or develops holes or cracks will soon start to look unsightly and your hard work will be for nothing.

The best approach is always to use different grades of gravel, starting with larger stones and working up towards the smaller gravel that is the top layer. This provides good drainage. Obviously, gravel will move and may slip down a steep driveway easily, especially when driven over

Driveway Surfacing Solutions: What Are My Options?

Option 1: Gravel

Gravel may seem like one of the worst options for a sloping driveway however it may be possible in some situations. Gravel driveways are built by adding stones to a base that has been created using soil and a fabric barrier that can prevent weeds from growing through.

The best approach is always to use different grades of gravel, starting with larger stones and working up towards the smaller gravel that is the top layer. This provides good drainage. Obviously, gravel will move and may slip down a steep driveway easily, especially when driven over.

However on a very gentle slope, you may still be able to use this material. By adding a plastic grid construction to your driveway base, you can compartmentalise the gravel, keeping it more or less in place.

These grids allow you to have the stones sit within the structure, rather than lie over the entire surface. On a slight slope this should be enough to keep the surface from slipping.

Both concrete and asphalt will be prone to becoming slippery, especially if there are dips that might pool water. Sheets of ice running down the length of a steep driveway will be dangerous for both cars and pedestrians

Option 2: Concrete/Asphalt:

Concrete and asphalt are laid in a very similar manner and onto a similar base. Both require good drainage that includes aggregate for drainage and an even earth base. Most steep driveways can be laid with concrete or asphalt, provided the layer is not too thick and will set before it starts to slip.

To prevent this, most contractors will split the driveway into sections and lay each with a gap or join between - allowing each to set independently.

There are a number of reasons this might not be the best material. Both will be prone to becoming slippery, especially if there are dips that might pool water. Sheets of ice running down the length of a steep driveway will be dangerous for both cars and pedestrians.

You may also find that water will run down the length of this type of driveway surface, running into the road at the bottom, causing issues for local drainage systems. Drainage channels are essential for these driveways.

In heavy rains, the sand can be eroded, and your paving stones may start to slip and move. This can happen on even a non-sloping driveway, but the effect is much worse on one that is steeper

Option 3: Paving Stones:

Paving stones are one of the most expensive options for a driveway, however they do offer some good practical solutions for a sloping driveway. If you choose a highly textured paving stone, you will get the grip you need and the stones can be laid in such as way as to provide grip where needed. The flexibility makes this a good option.

However, paving stones are generally laid onto a base of sand and therefore have less staying power than some other choices.

In heavy rains, the sand can be eroded, and your paving stones may start to slip and move. This can happen on even a non-sloping driveway, but the effect is much worse on one that is steeper.

Paving stones also take a long time to lay and are therefore more labour intensive. A slope only increases this downside.

Option 4: Resin Bound Surfacing:

This material offers one of the best choices for a steep driveway. A resin bound driveway is created using a mixture of aggregate stone and resin. This is mixed together, allowing each stone to be coating in the resin.

The mix is then pressed into an asphalt base that has been laid onto aggregate stone for excellent drainage. The overall result is a continuous stretch of driveway that has excellent grip and drainage.

●    Resin bound driveways are porous and will allow water to seep through them, preventing ice formation and ensuring the sub-base does not erode. If laid with the addition of drainage to the edges, even a very steep driveway will effectively deal with water build-up.
●    Resin bound driveways are not prone to being slippery, in fact, you can choose an aggregate that is slightly larger in size, to give even more grip where needed. The surface is similar to a road surface and therefore provides more than enough grip for even a very steep driveway.
●    The construction of a resin bound driveway is continuous - there are no joins or cracks and therefore it maintains its good looks and is not prone to slippage.
●    Your resin bound driveway will last for 30 years - even if it is laid on a slope.
