From localised flooding, to contaminated supplies, we explore the problems of inadequate drainage, and why a permeable driveway material offers the ultimate surfacing solution…
What Is A Permeable Driveway?
What is a permeable driveway? Put simply, one which radically reduces rainwater run-off, enabling it to drain far more effectively as a result.
By controlling stormwater at the source, additional problems, such as the infiltration of pollutants, are prevented, and water quality maintained.
In terms of permeable materials, porous surfaces such as dry-laid pavers and gravel offer the best prospect for drainage, although they often work best when combined with additional measures. Resin is the only permeable solution that functions effectively alone.
What Isn’t A Permeable Driveway?
Unfortunately, current building regulations don’t adequately differentiate between permeable and non-permeable surfaces, making it difficult to provide a definitive answer.
To achieve this, an absorbent substrate needs to be laid, with extra attention paid to ensuring that there are adequate gaps between individual flags and blocks. Each gap should be filled with either gravel or sand, enabling water to flow down into the soil below.
SUDs Compliance And Why It Matters
It’s no secret that building requirements change as often as British weather. Since 2008, stricter stipulations have come into effect, in response to persistently heavy rainfall and a rise in localised flooding.
Although the new regulations emphasise the importance of permeable paving, they do make a few exceptions, with non-permeable surfaces accepted as long as they’re complemented by adequate drainage solutions, such as soakaways or tanks.
However, this is very much on a case by case basis. In most instances, planning permission will be necessary, which involves a long and laborious process, with little chance of success. Moral of the story? Save yourself future hassle and heartache and plump for a permeable driveway solution instead.
Permeable Driveway Solutions: The Key Contenders
As one of the most cost-friendly materials available, gravel definitely courts all round affordability. What’s not quite so obvious is that it also offers a permeable driveway solution-if it’s combined with a reinforcing cellular structure as well.
Such combinations have a fair degree of drainage success, although it’s best to ensure that the foundations are higher in the centre, and gradually sloping away to the sides to increase water dispersion, and consequently speed up the rate of drainage.
Another advantage of mixing gravel with cellular structure is that it prevents constant gravel displacements, pinning the gravel in place, so that it remains completely compacted.
In terms of permeability, a combination of stones or pavers over a bed of sand can work well. This technique is known as dry-laying, and involves installing a paved or stone surface over a sand and gravel sub-base.
By implementing this measure, water can easily pass through the openings between each individual paver, improving drainage capacity all round.
-Resin: A Perfectly Porous Solution!
For traditional surfaces, heavy rainfall can prove hazardous, with pooling and puddling resulting in a shockingly slippy surface. And the problems don’t end there. At a deeper level, this excess water puts driveways at risk of localised flooding,
Thankfully, you can prevent this perilous proposition by replacing your surface with resin.
Fully SUDs compliant, resin offers a perfectly porous solution, enabling water to soak through the surface, and into the surrounding ground.
We hope that knowing exactly – What is a permeable driveway? – will now help you decide on your next home improvement project in terms of materials used.
Why Our Resin Bound Driveways Take SUDs Compliance In Their Stride
You can’t control the weather, but you can control what happens to your driveway during torrential downpours, by opting for a resin bound surface.
Resin’s sophisticated, cellular structure contains a high concentration of surface voids, making it far more effective in practice than other permeable alternatives.
It’s important to note that SUDs compliance doesn’t just concern the surface; the sub-base needs to be completely SUDs compliant as well. To achieve this, our resin bound driveways are constructed using precise specifications for the sub-base, encouraging water to drain away naturally.
Don’t let rain get the better of your driveway-opt for resin instead! This superlative surface material combats climatic conditions with style. Intrigued? Book your free site survey today by calling: 0800 1700 636.
