I have ordered twice now, a pleasure to deal with, easy and fast delivery, beautiful mulch!

One cubic yard covers about 324 square feet at a 1 inch depth, which is the typical install depth for mortar work and paver joints, so a small patio project might only need a fraction of a yard. For pool bases or larger paver jobs running closer to 2 inches, plan on roughly half that coverage per yard. Measure your square footage first, then decide on depth based on the specific job, mortar mixing and joint filling use less material than a full base course.

A yard is approximately 27 cubic feet. As a general guideline, one yard of material can cover an area of about 100-160 square feet at a 2-3 inch depth.

A ton is 2,000 pounds of material. As a general guideline, one ton of rock covers roughly 100 square feet at 2 inches deep, depending on rock size and density.

I needed 3 yards of top soil and that's what I got! Right on time and right where I asked it to be placed (Order# 2041).

Complete Your Outdoor Project

Most hardscape jobs pair this sand with pavers or flagstone and a base layer of crushed gravel underneath for drainage, since clay loam soils need that extra drainage layer to keep patios from heaving over Boulder's long freeze thaw season. If you're mixing mortar on site, you'll also want portland cement on hand. Some crews are shifting paver joints to clean chip stone instead of sand since it won't pump out, worth asking about if that's your project.

Mulch Mound Pro Tip

For mortar mixing at elevation, keep your water ratio slightly lower than sea level recipes call for, Boulder's dry air pulls moisture out of the mix faster than you'd expect, which can make mortar set unevenly if you're not watching it. Mix smaller batches more often rather than one large batch that starts drying before you've used it, especially on hot, dry afternoons in July and August.

Mulch Mound Pro Tip

A common mistake is using this sand as a paver base fill instead of joint fill, it's too fine and uniform for that job and will wash out or shift under clay loam's freeze thaw movement. Save it for mortar and joints, and use a proper crushed base material underneath the pavers themselves. Mixing up the two is the single biggest reason paver patios settle unevenly within a year or two.

Mulch Mound Pro Tip

If you're doing a hardscape project this spring, order your sand and your base gravel in the same delivery window so you're not paying for two separate trips, since hardscape season here runs hard from May through the first frost in October. Planning material drops around that window also means you're not stuck waiting on a supplier mid project when the weather is finally cooperating.

Working With Sand in Boulder

Boulder's clay loam soil holds water and drains slowly, so sand plays a specific role here rather than a general one, it is not a soil amendment on most jobs, it is a structural material for mortar and joint work. With clay loam underneath, patios and walkways settle unevenly if the base isn't right, and clean sand in the joints resists that shifting better than loose fines. At 5430 feet the freeze thaw cycle is aggressive from October through May, and a properly bedded joint holds up to that better than one packed with dirty or pit run sand.

Masonry vs Fill Sand

Masonry sand is washed and finely screened, the right choice for mortar work, paver joints, and sandboxes. Fill sand is coarser and less processed, better suited to leveling, bedding pipe, and filling low spots.

Bedding and Leveling

For pavers, screed a 1 inch sand bed over a compacted base rather than using sand to fix deep grade problems. A thin, even bed locks pavers in place. A thick one shifts underfoot.

Working With Moisture

Slightly damp sand spreads, screeds, and compacts far more easily than bone dry sand, which just flows back into your screed lines. Lightly wetting the pile before you work it saves real effort.

Answer

What's the difference between this sand and regular fill sand?

This is washed and finely screened, so it's much more uniform than pit run or fill sand. That consistency is what makes it workable for mortar mixing and tight enough for paver joints. Fill sand is coarser and less consistent, fine for grading or leveling but not for mortar or joint work where texture matters.

Answer

How much sand do I need for a small paver patio's joints?

Joint filling uses very little material, often well under a quarter yard for an average patio, since you're only filling narrow gaps, not covering the whole surface. One cubic yard covers about 324 square feet at 1 inch, and joints use a fraction of that depth spread across a small total area, so most homeowners order a partial yard.

Answer

When's the best time to install pavers with sand joints in Boulder?

Late spring through early fall works best, once the ground has fully thawed after the last frost around May 5 and before the first hard frost in early October. Installing outside that window risks the base shifting before it's had time to settle, and mortar work in particular needs stable, warmer temperatures to cure properly.

Answer

Can your truck get into a tighter Boulder neighborhood for delivery?

In most cases yes, but older neighborhoods near downtown sometimes have narrower streets or limited turnaround space. Let us know about any access concerns when you schedule, and make sure the drop spot is clear and reachable. Delivery is scheduled at checkout, and we'll work out placement details with you before the truck arrives.

Answer

Should I use this sand or chip stone for my paver joints?

Sand has been the traditional choice and still works well for most residential jobs, but chip stone is gaining ground because it resists pumping out under freeze thaw movement, which matters at Boulder's elevation. If you want the classic look and are comfortable with occasional joint top offs, sand is fine, if you want a lower maintenance option, ask about chip stone instead.'''}
