The gravel should be placed in layers and wetted to help with its compaction. Fill the trench until you are left with a space of about 3.5 inches (8.89 cm) for sand and the pavers. Add about 2 inches (5.08 cm) of sand on the gravel to help compact it further.
When pavers are set directly in sand – liquid falls on the pavers. This water seeps through the cracks and it keeps on going. Sand is permeable. Look at the beach. The wave washes over the sand. When the wave retreats all the liquid seems to disappear.
There are broadly three sizes of paver base gravel: fine, medium and coarse. Which one you use depends on your project: a fire pit will need a different type of gravel to your driveway, for example.
If you have poor drainage (clay soil, for instance, provides very little drainage) or want to build a driveway for multiple cars, this is by far the best and safest option. We’d also suggest using coarse gravel under your pavers if you experience heavy rainfall where you live, or if you have problems with runoff water.
Paver thickness is generally about 3- to 3 1/2-inches. Therefore, you need to dig a paver patio base depth of about 9 inches (22.86 cm) to accommodate any kind of paver. 5 inches (12.7 cm) of the hole will be filled with the base material for the base such sand or gravel.
1.5 inches thickAs you lay your concrete sand base, aim to make it less than 1.5 inches thick. Once the sand is laid, you'll need to level, or screed, it.
The most common gravel used for paver base are fine, about 3/8-inch, medium 1/2 to 3/4 inch, and heavy or coarse (1.5 inches). Bigger gravel stones are available but they're usually not used for paver bases.
The depth of the mortar bed should be approximately 35-40mm deep. Ideally starting from a right angle or straight edge, place the slab down. Gently tap with a rubber mallet or press down with your hands and use a spirit level to ensure to make sure the slab is level and in line with your proposed design.
Sinking pavers The sand should be 1 inch thick when laid. This is just the right amount of sand for the pavers to nestle in once they have been compacted. When too much sand is used, the pavers can sink further than they should as the support from the subbase is too low down.
A minimum of 100 mm of compacted base course (AP20) is required for under paving, this may need to be thicker in some situations (a stable concrete pad can be used instead of base course). Area to be paved (m2) x 0.1 (allows for 100mm of base course) x 1.3 (allows for compaction) = m3 of base course required.
Roughly crushed stone makes a good base for pavers that will be used more regularly. A base of 4 to 6 inches of well-compacted stone pieces provides a sturdy and stable foundation for nearly any type of paver installation, notes Concrete Construction, an industry website.
A long-lasting stone patio reqires a stable base. Pea gravel is a loose landscaping material composed of smooth, rounded stones between 1/8 and 1/4 inch. While pea gravel can be used as a mulch alternative, garden border and other landscaping purposes, it is not the best choice for a patio base.

How deep should my sub-base be? Generally, a flexible sub-base of unbound material needs to be at least 100mm deep, as does a bound sub-base of CBM/HBM. For bitumen-bound material, then 50mm is a typical minimum thickness.
0-20mm ballast is perfect for sub-base and concrete foundations. 20mm screened ballast is versatile and can be used on driveways, footpaths, oversite fill as well as sub-bases.
4 inches thickThe entire subbase and base system should be at least 4 inches thick—thicker if the engineer feels it is needed for proper support.
In climates that experience freeze-thaw cycles, the depth of a patio base would be 6 to 8 inches and the depth of a driveway base could be as much as 12 inches in depth on more cohesive soils.
The best gravel for a paver base depends entirely on the application. As long as you opt for any of the above noted installation methods or with a synthetic base installation which will use paver base panels and follow the proper installation of interlocking pavement, your project will stand the test of time.
Knowing how much paver base that your project will need requires that you have three measurements from your project. You need the length in feet, the width in feet, and the depth in inches that your gravel will fill. Using these measurements, you can complete the formula below to calculate the amount of gravel that you will need in cubic yards.
Thickness of Sand. The sand should not be thicker than 1-1 ½ inches once it has been smoothed and leveled. Creating a very thick layer will make the base soft and the pavers will sink in or move from their place.
Here are some important things to consider when choosing sand for creating a base for your pavers. You will be able to create the best and most durable base if you keep these factors in mind. 1. The Type of Sand for Pavers. There is only type of sand recommended by experts when it comes ...
The best kind of sand for this purpose is concrete sand. Cement is often combined with concrete sand and this mixture is then used to construct septic systems. This concrete sand is usually a mixture of brown, tan, and beige colors.
It is the most commonly used sand for pavers because of its high quality and durability. Other sands may be used but they aren’t durable and will crack in some time which will destroy your pavers as well. 2. Consistency of Sand.
Once you have placed two layers of crushed stone to create the base, the next step is to level it using a compactor. This will help your concrete sand lay down in an even layer. It will form a finishing cover for all the base elements and the pavers will be placed in a definite position that you want.
One of the most important things needed for the proper installation of pavers is sand. It is necessary to prevent the joints of the pavers from moving. Just like all other construction installations, you also need a base for pavers if you want them to not move from their place.
2. Consistency of Sand. You also need to pick the right consistency of sand to create the best base for your pavers. Use coarse sand underneath the pavers. This will allow for a flatter surface, strength, and tight compaction. 3.
Paver thickness is generally about 3- to 3 1/2-inches. Therefore, you need to dig a paver patio base depth of about 9 inches (22.86 cm) to accommodate any kind of paver. 5 inches (12.7 cm) of the hole will be filled with the base material for the base such sand or gravel.
Restraints are normally made from back polymer or plastic and can be purchased from any gardening center. Place the restraints along the edges of your pavers. They should be dug in every 16 inches and dig them into the base at different angles to secure them.
Pavers are stones used to create external flooring. Paver stones are extraordinarily strong and durable which is why they can support outdoor installations such as driveways, walkways, steps, and decks. In order to ensure the durability of your pavers project, the planning and layout process has to be well-thought-out. It is arguably the most important step when laying new pavers.
Before excavating, you can use spray paint to mark the areas that need to be dug. Make sure you make plans for water efficient landscaping and proper draining so that the pavers don’t hold water under them. Also take note of whether there are any underground cables or plumbing so that they can avoided while digging.
Your base will determine whether your pavers remain smooth and level or grow uneven with time. Qualities of a suitable base material include:
Choosing a paver base material is only one aspect of creating a quality base. The way you construct the paver base ultimately impacts its effectiveness and longevity. Perhaps the most practical tip for base construction is to take your time.
However you lay the foundation for your project, Nitterhouse Masonry has durable pavers to match. Our paver selection covers a broad range of styles and uses, ensuring you’ll find a versatile and affordable option. As a family-owned and operated business for five generations, we understand longevity.
Determining the paver base depth is actually very simple. For pedestrian only applications, it is adequate to have a 6″ paver base depth. For light to medium duty vehicle applications it is adequate to have 10″ of paver base. In some locations paver base is deemed unnecessary, i.e. Florida. However, I say paver base is necessary regardless of the location.
A long lasting brick patio, driveway, or walkway is the result of a properly installed base. As with anything, foundation is the key. By the time you’ve finished reading this post on paver base installation you should know almost everything you need to know about properly installing paver base.
Notes: It is important that during compaction the entire plate be in contact with paver base material. Fill in any low areas or level off any high areas in the paver base prior to compacting. If a compactor approaches a small low spot, the plate of the compactor will bridge over the low spot and that particular spot may never receive compaction resulting in future settling of the paver surface.
Before you start to build a paver base, you’re gonna need the following tools and materials:
The paver base is nothing more than the foundation for your pavers, the base consists of coats of aggregate under the pavers that give stability and strength.
The thin and fine texture of the material makes it more difficult to compact properly and, over time, the pavers can be uneven and sink. Another factor is the drainage of stone dust, it is very easy for pavers installed over stone dust to swamp during heavy rain.
Edge restraints are what helps to hold everything in place for years and they can be made of plastic, aluminum, or steel. Place the restraints around the area you want to cover with pavers and secure them into the ground with 12″ spikes.
S&S Pavers has been around the counties of Manatee and Sarasota for the last 10+ years. If you live in Florida, don’t hesitate to give us a call!
But it’s important to say a base of sand alone is not a good choice for areas with heavy traffic, like driveways or even patios, because the material can shift.
Preparing a good base for your pavers requires a lot of attention, so the best choice here is to count on the help of professionals. And if you are worried about the price, you can get a free estimate for your project.
Before moving on, your gravel base needs to be flat, without any bellies or rises of more than 1/8″. Any imperfections of more than this are noticeable in the final product.
To accomplish this, you’ll need to compact your gravel with a steel tamper (for small projects) or a plate compactor (for large projects). Compact your gravel in 2″ lifts, which means, compact your gravel 2″ at a time until the desired thickness is achieved. For example, if you’re laying a circle patio for your backyard, you’ll need to spread a total of 4” of gravel, 2” at a time.
In hardscape, your base includes the layers of aggregate directly under your paving stones that give your hardscape stability, strength, and permeable power.
Now, lay geotextile down over the soil. This material will provide a barrier between the gravel and the ground, keeping dirt and gravel from mixing.
In hardscape, your base includes the layers of aggregate directly under your paving stones that give your hardscape stability, strength, and permeable power.
We recommend excavating this deep because vehicular traffic requires a super sturdy base. The deeper the base is excavated, the more gravel you can add and compact.
You may be wondering, what does that mean? Setting grade (or grading) is simple—it’s how you control or manipulate a slope to ensure that surface drainage runs in a particular direction.
But if the paver is set onto sand which has been laid over a concrete surface, any moisture that seeps in has no place to go. It’s trapped between the paver and the concrete. This can lead to Efflorescence.
Once tile is glued to the floor, this does not happen. The same goes for thin marble. A porcelain tile needs to be at least 2 cm (a little over ¾ of an inch) thick in order to be set in sand. Marble is generally thicker – 3 cm. Also, there are some do’s and don’ts when using tile outside in freeze thaw areas.
This method of installation is similar to setting any interior floor tile. An adhesive mortar (made of cement and fine sand) is used to attach the tile to the concrete.
Many pavers are not subject to these issues. But some are. Material which is a light, consistent color could become blotchy as a result of efflorescense.
This thicker bed of setting materials allows installers to raise and lower individual pieces to avoid lippage.
Generally, marble and pavers are not installed using thinset.
Many pavers can be set using this method with no problems. But some natural stones could develop issues if set using this installation method.
