Paver Driveway Installation
For many years, the drive leading to a home in Scottsdale, Arizona was gravel, concrete, or perhaps asphalt. These materials, although practical, pale in comparison to driveway paving stones. There is a great deal more to choosing interlocking driveway pavers than what one might think.
In many cases, a poured concrete drive can cost a little less than a paver driveway. However, alternative materials, such as asphalt are far less durable and difficult to repair without destroying the overall appearance. Durability and ease of repair are issues that must be factored in when deciding on the driveway surface.
Brick Paver Benefits
Brick pavers provide several real benefits, making them great value, even when compared to a travertine driveway. Concrete driveway pavers are readily available in various shapes, colors, and surface finishes, and can be laid in interesting patterns to compliment the style of the home. The design possibilities are virtually endless.
There are benefits to a brick paver driveway, including:
Durability and Strength:
A brick driveway can withstand years of high-load situations, making them suitable for many different landscape designs. Modern driveway pavers last considerably longer than what might be expected from a poured concrete or asphalt surface.
Bricks, by far, are the best pavers for a driveway. Maintenance is minimal, and the durability is not in doubt. Bricks have been used for centuries, many brick roads are still in existence. Poured concrete, even when liberally laced with reinforcing mesh tends to crack.
The Surface is Non-Slip:
Brick pavers are manufactured from abrasive material, and have a textured surface, making them slip and skid resistant.
The pavers used in a pavestone driveway are produced from natural clay. Clay does not lose color under the Arizona sun, as such a driveway paved with brick is not only beautiful, it is environmentally sound and appreciates the value of the home.
Setting Brick Pavers on a Sand base
Paver installation begins when Artisan Block Masonry Scottsdale start grading and compacting the soil on which the pavers eventually sit. Paver driveway installation includes a drainage layer under a layer of aggregate.
Firstly, the aggregate is rough screeded. This step gets the level close to the design level. The depth of aggregate depends a great deal on the intended usage. In areas where heavy vehicles are expected, the aggregate base may be as deep as 12 inches. However, for light vehicular and pedestrian traffic, four to six inches is ideal. It is this base layer that serves as a support for the pavers which are set on sand.
In addition to establishing the grade, the aggregate base facilitates drainage and water run-off.
Once the sand layer has been compacted and screeded to the correct height, the pavers are set.
Many homeowners opt for a pervious driveway. Pervious pavers or permeable driveway pavers are one in the same thing. Pervious and permeable are often confused with porosity. Although the words are somewhat similar, they mean something very different. Porosity refers to the open spaces and cavities, both of which tend to hold water. Permeability, on the other hand, is a measure of how easy it is for rainwater to move through a porous paver.
When installed by professionals, pervious pavers do have many real benefits. When used on a driveway, localized replacement of individual pavers can be made without leaving unsightly patches. These pavers are also safer as they provide better traction for both people and vehicles.
Regardless of the specific pavers, once they have been placed on the sand base, they are compacted using a vibratory tamper. To ensure that the tamper does not damage the paving stones, a rubber mat is used to isolate the compacter from the pavers.
Once the individual pavers have been placed and compacter, the joints are filled with sand. Once the sand has been swept into the joints, the entire driveway is compacted again, filling the joints. This process helps to retain the pavers in place.
Although the cost is a little higher, many homeowners opt for polymeric sand. Polymeric sand, once exposed to moisture, hardens and sets firmly. Polymeric sand resists wash-out and erosion as well as helping to prevent weed growth between pavers.
A critical concern with any block paving driveway is edge restraint. There are a few ways to go about this, all of which are well known and used by paver installation companies near me. Edge restraints range from commercially available paver edging strips to spikes driven into the ground, to poured concrete sidewalks and curbs.
The majority of issues that arise with sand set paver installation arise from maintaining edge level, and sinking pavers. Edge restraints hold pavers in place.
The Advantages of Pavers Set in Sand
There are numerous advantages to sand set pavers, including:
Steps for Driveway Paver Installation
First off, installing driveway pavers is not an easy or simple task, it is always best to give the job to a team of professionals, people who have the right tools and know the proper installation techniques.
As a note of caution. Before the start of any work, contact the utility companies. Have them visit the site and check for underground piping or cables. Once utilities, if any, have been located and identified, stake out the location and depth.
Once the location of the driveway has been determined and marked, existing pavement and turf must be removed. Excavate to the correct depth. The correct depth includes the thickness of the paver, the depth of the sand setting bed, and the depth of the base material.
The installation company knows how much soil must be removed, a lot depends on the propensity of the soil in the driveway area to hold water or saturate. Depending on the specifics of the site, the base thickness ranges from 6 to 12 inches.
Compaction of the Subgrade:
Once the excavation has been completed, and before the geotextile fabric is laid, the subgrade must be properly compacted. The type of compactor used by professionals depends on the soil. If the subsoil is clay, a roller is used. If the subsoil is sand, a plate compactor is sufficient.
In the event, the installation is pavers over a concrete driveway, a level layer of sand, one to two inches thick is all that is needed. Many people, especially those with active youngsters prefer rubber pavers for their driveway.
Install Geotextile Fabric:
Geotextile fabric is often used in moist or wet areas, or in areas where the soil is expansive. If geotextile fabric is used, it must be used to separate virgin soil from the built-up base.
Base Material Installation:
The base material, which, depending on conditions, can be as much as 12 inches deep, must be installed in layers not exceeding four inches per lift. The material used for the base should be easily compactable granular type, the most common is gravel. Once the base material has been spread appropriately, it is compacted.
Edge Restraint Installation:
Edge restraints are set and secured with steel spikes. The importance of edge restraints cannot be over-emphasized as they provide lateral resistance to driveway loading, maintain continuity, and interlock the pavers.
Spread the Setting Bed and Install the Pavers:
Once the base material has been compacted, the contractor spreads a one to a two-inch sand base. The ideal base material is coarse-washed concrete sand or granite stone dust. Over this, a herringbone driveway or other pattern is installed.
Once the pavers have been laid, polymeric sand is swept into the joints and then compacted. This process continues until the joints are full, making for a solid surface. Many homeowners take the final step of sealing the drive, helping to protect the pavers from staining.
Pavers are ideal for driveways and other low-traffic areas. However, they are not recommended for use in areas that must accommodate high-speed or high-volume vehicle movement.
