Different Types of Driveway Paving
A paved driveway should be durable and withstand frequent traffic. The right pavement choice will also depend on your climate and your style preferences.
Consider consulting a professional paving contractor to ensure the project is completed correctly. A qualified paving professional will have the expertise, equipment and resources to handle the job efficiently and quickly. Contact Long Island Driveway Paving now!
Permeable pavers allow rainwater to pass through the surface of paved areas, seeping into the soil and gravel layers beneath. This allows for the natural replenishment of groundwater levels, reduction of local flooding and pollution, and even provides water filtration capabilities. This unique construction material is becoming a sought-after solution for urban planners and property owners.
While permeable paving is typically used to create driveways, patios and other types of outdoor spaces, it can also be used for roadways and parking lots. Using porous pavement can help reduce traffic noise, as it does not reflect sound waves like traditional paved surfaces. This can be beneficial to home and business owners who want to keep the interior of their buildings and properties free from distracting noises.
In addition to their environmental benefits, permeable pavers can reduce the amount of maintenance and repairs needed for your paved area. For example, they can help you eliminate the need for resurfacing and resealing, which saves time and money. They also provide a more stable, long-lasting surface that is less likely to crack or crumble. This type of paving also helps reduce mosquito populations by eliminating access to the standing water they need for breeding.
A permeable paved area requires a unique foundation to support the pavers and ensure that water can drain properly. The foundation is made up of a base layer and an infiltration layer, which are then covered by an aggregate base and topped with a permeable membrane. The pavers are then installed over this foundation, and an outflow pipe containing holes along its length is placed in the bottom layer of the permeable membrane. Water is slowly released into these overflow pipes and back into the drainage system.
Using permeable pavers for your driveway can reduce the amount of puddles and ice that forms during heavy rainfall, which can be a safety risk. These pavers can also help you avoid the need for salt and other de-icing products, which are harmful to the environment. Permeable paving also tends to melt snow and ice more quickly than other paved surfaces, as it has a higher surface temperature due to tempered airflow in the base drainage layer of the paving system.
Concrete
Concrete is a long-standing and cost-effective choice for driveway paving, and can be made to look unique with borders, colors, stamped patterns and other custom finishes. It’s also durable and can withstand traffic loads of up to three tonnes.
Unlike asphalt, which can crack and stain over time, a properly installed concrete slab has an expected lifespan of 30 years or more. Concrete is also more versatile than other options, such as pavers or gravel, and can be designed to resemble brick, stone, tile, slate or even wood.
Like any major construction project, a concrete driveway requires thorough planning. The subsurface must be graded and prepared to ensure a firm base, while drainage must be considered to avoid pooling water or moisture in the slab. Before placing the concrete, the ground must be stabilized with a mix of gravel and crushed rock to provide support and prevent movement in the future.
Once the subsurface is ready, a formwork must be constructed to hold the concrete in place while it cures. The forms should be sprayed or brushed with form oil to prevent leaks. A concrete pour can be very messy, but a professional crew will work quickly to fill and compact the wet material. During the concrete pour, it is important to use the correct ratio of cement to water to maintain a strong and dense slab.
After the concrete has been poured, the paving stones can be laid. The laying pattern is critical to the long-term durability of a residential driveway, as the bond line must be discontinuous to resist repeated stress from wheel loads. The industry recommends herringbone paving patterns, which feature alternating bond lines that are short and long to minimize the number of joints.
Once the paving stones are in place, they can be leveled and smoothed with various tools, such as screeds, rollers or hand floats. The resulting finish is both functional and attractive, with a surface that reflects the natural textures of the individual paving stones. If desired, a final coat of sealer can be applied to protect the stones from weathering and UV radiation.
Exposed Aggregate
Concrete aggregate – also known as exposed aggregate or rock gravel concrete – is a beautiful and extremely durable paving option. It’s a great choice for driveways, as it provides leading traction and can be customised with different stone sizes to suit your taste. You can also use this style of paving for pathways, patios and entranceways for a consistent look that blends into your landscaping or existing structures.
Exposed aggregate involves removing the top’skin’ of concrete to reveal decorative coarse aggregate (which may be batched into the concrete mix or added after). There are thousands of possible combinations of deco-aggs, including natural stones like granite and limestone as well as recycled building materials, crushed glass, brushed concrete, terrazzo and even industrial byproducts like slag. A variety of colour and texture options are available, too.
An exposed aggregate finish makes the concrete surface more rugged and textured, which is both eye-catching and highly practical. The rougher surface helps to reduce the risk of slipping on a wet or dirty surface, and it’s also easier for cars to grip the surface compared to standard concrete. This type of concrete is particularly suited to areas around pools and patios, as it’s an ideal choice for wet surfaces that often see heavy foot traffic.
This type of paving is relatively low-maintenance, requiring only annual re-sealing and occasional sweeping to keep the surface in tip-top shape. However, due to the rougher surface it can be more difficult to repair if damaged than a smooth, painted or stamped concrete finish would be.
Exposed aggregate concrete is more expensive than a standard concrete finish, but it can add a lot to the visual appeal of your home. It requires specialised techniques to pour and finish the concrete, so it’s essential to use an experienced professional for this type of work. Additionally, it’s more difficult to match the exact texture and finish of this type of paving if repairs are needed in future, but this isn’t something that can’t be overcome with careful planning. If you want to ensure your exposed aggregate paving is always looking its best, you should consider using a quality sealer.
Tar & Chip
Although it is less common than concrete, asphalt, or gravel driveways, tar and chip (also known as “chipping seal,” “chip-and-seal,” or “asphalt and stone”) can be an excellent choice for your home. In addition to their classic look, tar and chip driveways are generally cheaper than other options. This is because tar and chip is not as thick as traditional blacktop, so it does not require as much material to build.
To create a tar and chip driveway, the surface of your existing driveway is thoroughly cleaned, then graded so that water drains away from the property. After that, a layer of hot liquid asphalt is applied to the prepared area. This is followed by a layer of roughly crushed, similarly-sized gravel. This is then compacted using heavy machinery to ensure that the stones are securely embedded in the asphalt.
The surface of a tar and chip driveway is slightly rough, which provides good tire traction in rain or snow. It is also easy to maintain, as it can be swept clean of leaves and other debris. However, the rough surface can be scraped by snowplows that apply too much pressure, so it is important to plan your plow route carefully.
Another great benefit of a tar and chip driveway is that you can choose from a wide variety of colors of stone to create the desired aesthetic. This gives you a unique opportunity to make a personal touch to your home and driveway that sets it apart from other properties in the neighborhood.
As with other types of paving materials, the prices for tar and chip are influenced by a number of factors. Labor and material costs, location, and market demand all play a role in pricing. Additionally, since the bitumen liquid poured on the stone chips derives from oil, fluctuating energy prices can impact overall costs. As a result, accurate pricing for a tar and chip driveway can only be given after an on-site assessment. For this reason, it is typically best to work with a professional contractor familiar with the specific material and installation process.
