Almost every component of your property, including the driveway, gives you the opportunity to make eco-friendly choices, so why not take advantage of them? There are a few specific objectives that should be met by a “green” alternative to an asphalt driveway. By enabling water to permeate through the driveway rather of allowing it to flow off the top, it helps manage runoff, which in turn helps avoid floods and replenish ground water. Because the surface water is absorbed by the permeable driveway material, and the water is then filtered by the soil below, this prevents pollutants from your automobile and other sources from getting into the ground water or polluting the water in storm drain systems.
Additionally, the accumulation of heat that might occur with more conventional materials is avoided by these driveways. The approach that is most suitable for you will be determined by the laws that govern your region, the preferences you have, and whether or not you want a method that you can do on your own. Because green driveways are not the standard, it is possible that you will need to pay someone for consulting, or you may need to have an expert design or build your green driveway. Driveways of this kind are suitable for both newly constructed residences and those that have previously been erected.
Grass Paver Driveway
Grass may seem to be an unusual material for a driveway given that one of the primary functions of a driveway is to divert vehicles off of a homeowner’s yard. However, the operation of a grass paver driveway is rather unlike to that of a conventional lawn. A grass driveway is not created by merely growing grass in the ground; rather, it consists of multiple layers. The very first stratum is composed of sand. On top of this layer of sand is a plastic mesh that has holes in it that have been filled with sandy loam. Through the holes in the mesh, the grass grows. The automobile is held up by the mesh, which at the same time shields the grass’s roots from damage. Because of the perforations, water is able to travel through the soil, and the layers of grass and sand filter any runoff that may occur.
Permeable Concrete Pavers
Consider using concrete pavers that are permeable rather than a solid surface that blocks drainage if you want your driveway to have a more classic appearance. Water is able to drain through the driveway surface because the pavers have spaces between them. In the same manner that you would require an adequate layer below the pavers if you had a grass driveway, you would need a bed of crushed stone. You may create the appearance of tiles by leaving the pavers unadorned, or you can go for a more natural effect by allowing grass to grow in the spaces between the stones. The grass prevents dirt and other debris from getting into the spaces. If you choose not to use grass for this driveway, you will need to sweep the pavers once a year to prevent debris from becoming lodged in the spaces between them. Bricks are another viable choice to consider.
Porous Concrete Pavement
Concrete that is porous or permeable is an excellent option to go with if you want an environmentally friendly driveway that has the appearance of a regular driveway and will blend in well with the others on the street. The composition of porous concrete is comparable to that of conventional concrete in many respects. According to Biofriendly Planet, however, porous pavement contains very little to no sand or other finer components like those found in the less environmentally friendly variant. Instead, it is mostly made out of crushed rock with sufficient cement to keep the material together. The voids that are produced make it possible for water to move through. Because it seems to be practically indistinguishable from conventional concrete, this option is likely to be in compliance with any requirements that exist in your region governing the building and appearance of the driveway.
Gravel and Sand Driveways
The passage of water is made possible by the use of sand and smaller stones, both of which are elements that are extremely kind to the environment. In addition, they are not costly and can be put in place in a driveway in a short amount of time. According to the website Driveway Guide, both types of driveways need regular care in the form of raking or sweeping to return the gravel or sand to its proper location. Stones and sand may be found in a number of hues, and although this option might not be as aesthetically attractive as some of the other possibilities, it does have the advantage of seeming less cluttered and disorganised. This makes it much simpler to choose a material that suits both your aesthetic and functional needs. It is recommended to use smooth stones rather than gravel since smooth stones enable water to flow more efficiently into the ground than gravel does.
