How To Compact Gravel For Concrete
When compacting gravel designated for a foundation of a concrete slab, it is best to use a machine. A plate compactor or jumping jack will compact the gravel in a fraction of the time that it would use to use a hand tamper.
If you have more than 5 of gravel, youll have to compact gravel more than once. It is recommended to compact every 5 to ensure even compaction throughout the bed of crushed rock.
Compactors are widely available at any rental store. Big box stores that do rentals will almost certainly have one or many to rent by the hour. While heavy, they are small enough to be loaded into the back of a family van or truck without much hassle.
The job takes about an afternoon, depending on the size of your slab, and youll find the cost justified considering the time youll save versus hand tamping. Compacting manually takes much longer, as youll need to tamp every inch or so to achieve, or come close to achieving, compaction anywhere near what the machine compactors can accomplish.
Compact The Soil And Lay Landscaping Fabric
Once youve got the soil cleared away, compact the soil with a tamper.
Then roll weed blocking landscaping fabric across the entire area and secure with stakes. This will prevent dirt from mixing with the gravel and making a muddy mess in the rain, and will stop weeds and roots from growing through.
Flagstone Patios That Are Set In Sand Are Vulnerable To Ants And Wash
Occasionally Ive seen a paver patio messed up by ants. But with flagstone patios that are set in sand ants always attack. I suppose its because the joints are inevitably wider with flagstone and/or because the flagstones are varying in thickness meaning you end up with deeper sand in some places. Whatever the exact reason, I can tell you that all of the flagstone patios that I have seen that are set in sand eventually get run amok by ants.
Another reason to use screenings is because screenings also make an excellent joint filler.
You do not want to use sand, even course sand between your flagstone joints because it can wash awayunless of course your flagstones are absurdly tight. For pattern-cut flagstone, yes, you can maybe get away with using sand as the joint-filler. Just make sure the base is course sand, not fine. You will need to use fine sand for the joints however because of how tight they are. Again, ants love fine sandbut in this application, pattern-cut stones, tiny jointsfine sand will not be the end of the worldso long as the base is course, of course. Thats for pattern-cut flagstoneor any flagstone where the joints are super tightin those cases you can maybe get away with sand, so long as you follow the guidelines that Ive set earlier in this paragraph. For irregular flagstone, or any flagstone with a joint wider than a quarter of an inch, you really really should try and avoid sand, and instead use stone dust.

Crushed Stone Vs Pea Gravel: Whats The Difference
Whether youre looking to add some landscaping or are trying to find the best aggregate for a project, two popular options you will consider are crushed stone and pea gravel. Some people may believe that these two products are interchangeable, and while each can be used for similar applications, theyre not entirely the same.
To the untrained eye, crushed stone and pea gravel may both just be some form of rock, but each one serves its own purpose and has its own specific set of uses. From shape and size, to applications, to even cost, these two materials are different. Thankfully, if youre stuck in the crushed stone vs. pea gravel debate, well clarify it all for you below.
What are the size and shape differences?
When you compare the two, the biggest differences youll notice are the sizes and shapes. Although gravel can come in a variety of sizes, pea gravel is typically 3/8. It is often softer to the touch too, thanks to its rounded and smooth sides. Plus, pea gravel comes in a variety of different colors, including neutral colors like brown and gray, as well as more eye-catching colors like red and blue.
Crushed stone is available in a variety of sizes, from 3/8 to 4. Because it is literally crushed stone, there is no consistency to its shape. The edges tend to be sharper and it feels rougher to the touch than pea gravel. Also, most crushed stone will either be in a white or gray hue, giving you a more neutral look than the colorful pea gravel.

Can I Use Gravel As A Paver Base
If youre thinking of laying a new patio then this article should help ensure you get strong, level foundations for your pavers.
You can use gravel as a paver base as it performs the same function as paver base itself. While paver base is coarser and locks together more tightly than gravel, they are both used to form a thick layer over your landscape fabric which is then covered with sand that you lay the pavers on.

List Of The Pros Of A Pea Gravel Patio
1. It is a low-cost option that can produce exceptional results.You can usually create an entire patio from pea gravel from 1 ton of material.

Building A Gravel Patio
Gravel can make an attractive, long-lasting and economical material for patios or garden seating areas. Before you select a gravel material, though, you need to spend some time preparing the base. Typically, gravel patios are surrounded by an enclosure made of cement, stone or brick, or a combination of materials. The strongest enclosures have a base of cement, topped with decorative elements, such as slate or stone.
Once the enclosures complete, youll excavate the patio area, removing the topsoil so youre left with the hardpan. This soil makes a sturdier base for your gravel patio than soft, spongy topsoil. When excavating, keep in mind that your gravel should be at least 4 inches deep from the bottom of the enclosure. Use square shovels and a level to ensure an even surface and install drainage pipes, if necessary.
The next step in making a gravel patio is installing a gravel base. Spread a layer of road rock over the patio surface, filling the area three-fourths full. Road rock, sometimes called road base, contains larger pieces of gravel that are angular in shape. Road rock is not only less expensive than other types of gravel, but the angular pieces lock together, forming a strong base for your patio. Most landscaping firms or contractors can supply this for you. After laying the foundation, tamp it down with a plate compactor, which is a small machine available for rental at rental supply stores.

How Thick Should The Gravel Layer Be
Again, this depends on your application, as something like a heavy-traffic driveway will need tougher foundations than a low-footfall walkway. And , different soils behave differently, and you may need to compensate for inadequate natural drainage.
Well look at the anatomy of the paver base in more detail later, but here are the basic rules for gravel layers.
Most experts suggest at least 4 inches for the gravel or crushed stone layer, then an extra inch for a layer of sand. Weve always gone for at least 6 inches for the gravel layer: yes, its a bit more digging, but we reckon its worth the effort for that extra peace of mind. For driveways, some builders insist on digging down a foot, ensuring that you have one tough and reliable paver base layer.
Of course, the local dirt has as big a part to play in paver construction as the actual application itself. If you live in one of the rainier states or have clay soil, the deeper the drainage layer, the better.
Even if youre lucky enough to live in a dry or temperate climate, its wise to overcompensate when it comes to drainage. You may experience a burst water main, flash flood or unexpected runoff, and its best to be prepared .
Once youve decided on the depth of gravel you need, its a simple calculation to decide how much paver gravel you need to order. Our usual rule is to add 10% on top of that as a contingency you may need it, and if you dont, gravel rarely goes to waste in the busy gardeners world.
Do You Need Gravel Under Concrete Patio Slab Footings
Ive been watching some of my neighbors recently pour small concrete slabs in their backyards for various projects. From what I can tell, it seems like everyone has gone about the job differently. One of the main differences is if you need gravel under the concrete patio, slab, or footing.
You do need gravel under a concrete slab, footing, or patio. Gravel provides a solid foundation for your concrete as it can be compacted. It also improves drainage, preventing water from pooling beneath the concrete.
While some may argue that very solid soils such as clay provide just as good a base as gravel, they still do not provide adequate drainage. This leads to pooling moisture and erosion, which causes a slab to sink and crack.
In this article, well go over all the reasons to add gravel beneath your concrete slab. Well also briefly go over the process of what making a concrete slab entails and some instances when pouring concrete right onto bare earth might be appropriate.

Place The Gravel And Prepare For The Shed
The process is coming along nicely. You have the permits and the right shed plans. The ground is properly level and the gravel shed base is dug to a 4-6 inch base. The foundation is framed with a 2 foot extra length and width frame. The frame is squared and the soil is tamped. The right gravel is bought and delivered into the framed area.
Lots of work done already and a little more to go. Now place some sand on the vapor barrier to protect it from the gravel. Then place the gravel in the foundation and tamp it again with your Ames manual tamper. If it is a large area to tamp then go with the the one by Dirty Hand Tools as we discussed above. The gravel is now tamped and level so move on to the building process.
