how to lay pavers on crusher run stone | home guides | sf gate

Crusher run stone is crushed limestone used to create a base under landscape pavers. The texture of the crusher run stone allows for excellent compaction, which in turn creates a solid, steady base that will support pavers exposed to constant traffic. This dry method of laying pavers is more straightforward and less messy than using mortar. If installed correctly, pavers with a crusher run stone base will last years without any need for maintenance.

If installed correctly, pavers with a crusher run stone base will last years without any need for maintenance.

Call local utility companies to inform them of your intended digging. Wait for representatives to come and identify any buried water pipes, phone lines or electrical wires in your marked area. Adjust the position of the digging area if needed to avoid areas with buried utility lines.

Remove any plants or sod with a shovel. Dig down to a depth of 6 to 8 inches. Pile the excavated dirt in an out-of-the-way area. Smooth the bottom of the trench using a rake. Lay a two-by-four on the bottom of the trench. Place a level on the board. Check to ensure that the width of the trench is level and that the length of the trench slopes away from any nearby buildings at a rate of 1/4 inch per foot. Fill in any dips or impressions with some of the removed dirt, tamping it down in place.

Lay a piece of landscape fabric over the bottom of the trench. Pull on the edges of the fabric to remove any wrinkles or creases. Press the sides of the landscape fabric against the walls of the trench.

Pour a 1-inch layer of crusher run stone into the trench. Spread the stone out as evenly as possible using a rake. Push a plate compactor over the crusher run stone to tamp it down. Place the level on the layer of stone to ensure that it is even. Repeat this process three additional times to create a 4-inch layer of crusher run stone.

Place edging restraint along the sides of the trench. Position the edging restraint tight against the walls of the trench with its bottom edge resting on the layer of crusher run stone. Drive anchor pins into the holes in the bottom of the edging to hold it in place using a rubber mallet. Insert one anchor pin every 6 inches along the length of the edging.

Pour a 1-inch layer of coarse sand on top of the crusher run stone. Rake the sand until it is smooth. Push the plate compactor over the sand to tamp it down. Lay a level on top of the sand to ensure that it is even.

Lay the first row of pavers on top of the sand along one of the trench's shorter edges, working from left to right. Position the pavers as close together as possible in a straight line. Tap each paver in place with the rubber mallet. Lay the second row of pavers against the first row, working from right to left. Tap each paver in place with the rubber mallet. Place the level on each row of pavers in turn to ensure that they are even. Continue to lay pavers in this manner until the entire layer of sand is covered.

Pour a thin layer of jointing sand on top of the pavers. Brush the sand around over the pavers with a broom, allowing the sand to fall in any gaps between the pavers. Push the plate compactor over the pavers in north-south rows. Then push it over the pavers again but this time in east-west rows. Repeat this process until the gaps are completely full with jointing sand. Brush off any excess loose sand.

stone dust doesn't belong under pavers. heres why. - unilock contractors

When it comes to building walkways or patios with interlocking concrete pavers, theres one material commonly used for bedding thats fallen out of favor (although not with everyone) in a big way: stone dust.

Stone dust, sometimes called rock dust, is a byproduct of crusher run thats provided the bedding layer for many a paver project over the years. While it can work in some construction applications, theres a growing recognition that sand washed concrete sand in particular has proven far more stable and exhibits properties that make it superior to stone dust for bedding in a number of ways.

One would be hard-pressed to find stone dust underlying major municipal or commercial projects, for instance. Not because of overbearing or arbitrary regulation, but because best practices reflect the fact that its ill-suited to that purpose.

Stone dust poses some well understood threats to the physical integrity of paver projects. Water retention is one, and a pH level that can steadily eat away at the pavers themselves is another. These are objective material properties that cant be refuted, certainly not with anecdotes.

Stone dust is a fine material that absorbs moisture readily, then releases it slowly. The same properties that work wonders for organic gardening can wreak havoc underneath pavers, causing efflorescence and allowing them to settle or shift easily under load. In extreme frost-thaw cycles, water-soaked stone dust can actually pump up through the joints, shifting pavers in the process. A garden path that went unscathed through last years mild winter can suddenly shift and heave when more extreme conditions arise.

The Interlocking Concrete Pavement Institute (ICPI) offers web-based resources specifically designed to educate contractors and homeowners about the recommended materials and techniques to use for paver projects. Their mission couldnt be more focused.

They, and many others, recommend whats commonly referred to as washed concrete sand, a coarse-grained sand that complies with CSA A23.1 and ASTM C33 standards. Without doing a deep dive into material specifications, arguably the most important property of that sand is that it wont pass through a #200 screen at least no more than 1% of it for a given volume. Your local supplier should be able to confirm that the sand they sell complies with the appropriate material standard.

In contrast to stone dust, concrete sand provides superior performance over time. It doesnt eat away at pavers, it affords excellent drainage, and it compacts well. The coarse texture also acts to hold pavers in position, providing a stabilizing buffer that allows the ground underneath to shift without shifting pavers.

Alas, pavers have been set in stone dust for years, and some contractors just arent convinced theres a reason to change. A quick Internet search reveals all kinds of opinions on the topic from folksy advice to dreary academic analysis. But there are just too many variables to put significant stock in anecdotes that contradict materials science.

Admittedly, a full understanding of what works best is somewhat elusive. Part of it is time noticeable material problems dont appear immediately. As noted previously, part of it is weather mild conditions may hide the inferiority of materials until theres a shift to more inclement weather. Part of it is load bedding thats fine for a garden path wont hold up on a well-traveled public courtyard. Shaped by only the partial intrusion of any of these effects, pavers laid in stone dust can last for years without significant heaving, settling, or shifting.

For one thing, the use of stone dust as a bedding layer voids the product warranty of many paver manufacturers. This is largely due to the sizeable increase in efflorescence the chalky white salt deposits that form on pavers when excessive moisture is present underneath.

More subtly, saying that coarse sand performs better over time is not the same as saying stone dust never works. What it says is that the risk of settling, shifting, efflorescence-related problems, or heaving is simply higher with stone dust than with sand. Drier climates and the absence of a hard frost-thaw cycle can mask the inferior properties of stone dust to one degree or another.

No matter which side you favor, its important to recognize that the quality and success of a paver project is determined by many variables. So, if your business is based on relationships and the strength of your reputation, theres no better argument for eliminating controversial bedding material as a risk factor, regardless of what has worked in the past.

With your business at stake, its something to consider carefully before your next big job a simple choice between materials might determine whether it becomes a showcase project, or just another cautionary tale.

choosing the right paver base material | nitterhouse masonry

Concrete pavers are aversatile, attractive additionto any outdoor residential project. Their ease of installation makes for simple, efficient and timely home set-up with the ability to use the space immediately. To reap the full benefits of your hardscaping for years to come, its essential to select and use proper paver foundation materials.

When selecting a base, youre choosing the materials that will anchor your pavers. Each material exhibits properties that either helps or hinders your paver arrangement. For long-lasting, resilient pavers, consider the different types of paver bases to make the best decision for your budget and project.

A sand paver base is one of the most popular options due to sands accessibility and spreadability. However, sand is not an ideal base on its own. Over time, sand shifts and can create an uneven foundation. If your foundation is anything but level, your pavers will show it.

Sand is often used in conjunction with crushed stone for increased durability. Because sand comes in many degrees of fineness and coarseness, not all types are suited for use as a paver base. TheInterlocking Concrete Pavement Institute recommendswashed concrete sand as the best base sand for pavers.

Concrete sand, also known as bedding sand, is coarse and doesnt trap excess moisture beneath the paver surface. This allows pavers to drain after a heavy rain and maintain their structural integrity over time.

A crushed stone paver base is made of small stone pieces that have been broken and screened for uniformity. According tothe Minerals Education Coalition, common rock types processed into crushed stone include limestone, dolomite, granite and trap rock. Stone aggregate comes in a variety of sizes, but most expertsrecommend 3/4-inch gravel for paver bases.

Crushed stone makes a solid paver base because it allows water drainage and is easy to work with. Like sand, crushed stone comes in several varieties. The best aggregate for paver bases is a quarry processed dense grade aggregate. Quarry processing creates a combination of 3/4-inch crushed stone and stone dust. This mixture binds well and increases durability, making it one of the best materials for maximum strength and cohesion.

Recycled concrete aggregate (RCA) is a crushed stone alternative with environmental benefits. Crushed stone is mined as virgin aggregate before it is broken into pieces and sold. RCA is made by breaking down existing concrete into gravel. The RCA process has a smaller carbon output and takes less energy than mining virgin aggregate, making it a sustainable option.

Though RCA functions similarly to crushed stone in a paver base, it is impossible to know the different rock mixtures it contains. This unpredictability may make RCA a less reliable base choice when compared to crushed stone. If youre interested in an RCA paver base, talk to your provider about the quality of their materials to ensure your project runs as smoothly as possible.

Stone dust is a powdery mixture of finely ground stones that has a sand-like texture. Though it can be a helpful base ingredient when mixed with other materials, most professionals recommend that you never use stone dust on its own as a base.

Stone dust and finely ground stone called screenings fall into a material category that has excessive amounts of dust particles called fines. The fines trap large quantities of water that prevent the base layer from adequately draining. According to the Interlocking Concrete Pavement Institute, this water storage compromises a bases ability to bear and distribute loads. To keep your pavers safe and prevent them from shifting, opt for a base material with a little more durability.

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.

Laboring over three base layers before you even begin to lay pavers may seem like a wasteful task. But the amount of time and precision you put into making your base layers the correct thickness, compactness and evenness will pay off. A proper base can keep your pavers beautiful and functionalfor 20-25 years. If youre looking for stunning results, base building is not something to be rushed.

Paver bases require several inches of excavation. Before you start digging, youll want to ensure you wont hit any underground utility equipment. Calling the number 811 will automatically direct you to your states call center and allow you toset up an inspectiontwo to three days in advance.

When your utilities are marked, its time to dig a base. The purpose of this digging is twofold. It exposes area for the pavers to nestle into, and it clears loose dirt from the installation site. Loose soil is unstable and cant bear as much weight as hard, compacted earth. Removing this layer provides a strong foundation for your paver base.

For added security, its crucial to compact your subgrade soil with a vibrating plate compactor. The more compressed your subgrade soil is, the less it will shift and settle over time. This will help keep your pavers level and in place for longer.

In addition to removing loose soil and compacting the subgrade soil, remove any grass, roots, large rocks or other debris from the paver installation site. This gives you an even surface to layer and build upon.

Granular soils make strong subgrades that drain well, whereas clay soils are weaker. For that reason, the Interlocking Concrete Pavement Institute recommendsa seven-inch subgrade thickness for granular soiland a nine-inch subgrade for clay soil. Be sure to match your soil with your excavation depth to keep your base sturdy.

In addition to depth, youll need to incorporate a slight slope gradient in your base for water drainage. With your pavers location and use in mind, determine which way the subgrade will need to slope to direct water away from the areas youll use the most. Your paver site should besloped 1/4-inch per footto allow proper runoff. This will prevent water buildup on the pavers themselves and help keep water away from your home.

As detailed above, the best paver base is a quarry processed crushed stone subbase and a washed concrete sand base. Crushed stones stability paired with sands spreadability makes a manageable, long-lasting base duo.

For best results, use a dense grade stone aggregate and concrete sand that complies with American Society for Testing and Materials standards.ASTM C33andCSA A23.1is the recommended sand quality, butASTM C-144andCSA 179graded masons sand is also acceptable. Talk to your supplier to make sure your materials align with these standards.

When you begin to build your subbase, youll want to scatter thin layers of crushed stone and then compact and slope them. Compacting increases your bases load-bearing abilities, while sloping maintains the proper water drainage plane.

To compact subbase layers, youll need to rent a vibrating plate compactor. These machines look like small, simplified push mowers and are typically manually operated. Their engines vibrate a base plate, which can be used to compress your subbase particles closer together. Vibrating plate compactors come in a variety of sizes, so be sure to rent a machine that makes sense for the size of your paver project.

For maximum effectiveness, complete your compaction one thin layer at a time. Slightly wetting your crushed stone subbase may aid the compaction process. The more tightly-packed your subbase begins, the less likely youll experience long-term settling underneath your pavers.

Your subbase thickness will depend on the type of subgrade soil youre covering and the way your pavers will be used. Because its weaker, clay soil requires a thicker subbase than granular soil. It is standard to usea four-inch crushed stone subbaseover granular soil and a six-inch subbase over clay soil. These thicknesses work well for everyday pedestrian traffic.

If your pavers are located around a pool or will receive vehicle traffic, your subbase should besix to eight inches thick. Extra thickness beyond six to eight inches may help reinforce pavers that will support extremely heavy vehicles like semi-trailers or campers.

To protect your pavers from unevenness, double your subbase thickness in areas that might freeze during the winter. The extra distance between the subgrade soil and the actual pavers will help mitigate any movement due to the ground freezing and thawing.

As you lay your concrete sand base, aim to make itless than 1.5 inches thick. Once the sand is laid, youll need to level, or screed, it. There are many types of tools to help level the sand base. You can use a flat, heavy 24 with an attached handle to smooth out the sand, or you may consider renting a dedicated screed rail for the project. Whatever you decide, the end goal is to have a completely smooth surface for your pavers.

When youve screeded your base, its important to install your pavers quickly and carefully. Leaving your base out overnight increases the chances that wind, debris or people will disturb the flat surface. Your base may not be the only structure at stake if you dont work quickly. Leaving pavers out overnight can increase their moisture content, which may make themsusceptible to efflorescenceafter installation. Efflorescence is the presence of salt deposits on your pavers, which gives them a white or greyish tint.

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 youll find a versatile and affordable option. As a family-owned and operated business for five generations, we understand longevity. You can trust that our pavers will provide years of aesthetic appeal and convenience after installation.
