Colorado’s freeze-thaw cycles can be tough on outdoor spaces.

As temperatures repeatedly move above and below freezing, soil can expand and contract, potentially affecting pathways, edging, drainage areas, and other parts of your landscape.

Before winter settles in, take a quick walk around your property and make note of any areas that may need attention come spring.

A little planning now can make your spring project list much easier.

Photos are a great starting point, but landscape materials can look very different once you see them in person.

Color, texture, size, and variation can all affect how a material looks in your finished landscape, especially in different lighting and alongside your home, plants, or other hardscape features.

If you’re deciding between a few options, stop by Colorado Materials and take a look before making your final choice. Seeing the materials up close can make the decision a whole lot easier.

Looking for a material that’s practical, versatile, and works well in a variety of Colorado landscapes?

Breeze is a finely crushed material commonly used for pathways, patios, and other compacted surfaces. Its smaller particles allow it to compact into a firm surface while maintaining a natural look.

Not sure if breeze is right for your project? Our team can help you choose the best material based on how and where you plan to use it.

Summer can be hard on the most-used parts of your landscape.

Before winter arrives, take a look at the areas that saw the most activity this year: pathways, patios, landscape beds, gravel areas, and high-traffic spaces.

Maybe a pathway needs fresh material. Maybe mulch has thinned out. Maybe decorative rock has shifted or a hardscape area needs attention.

Colorado Materials stocks decorative rock, mulch, base materials, sand, flagstone, pavers, edging, and other supplies for projects big and small.

Fall doesn't have to mean starting over. Sometimes it's simply the right time to refresh what you already have.

What makes one landscape rock feel completely different from another?

It's not just color.

Size, shape, texture, and natural variation all influence how stone looks once it's installed.

A smaller rock like 3/8" Grand Mesa Gray creates finer texture and detailed coverage. Rounded Glacier Blue River Rock provides a smoother, more natural look. Larger Pueblo Gray Cobble adds more visual weight and definition.

And because natural stone can vary in color and appearance, seeing materials in person can make choosing much easier.

Come by to compare side by side before making your decision!

When Colorado snow starts melting, where does all that water go?
It's a question worth answering before winter.

Take a look around your property this fall. Areas that already collect water after rain may become trouble spots when snow begins melting. Drainage features can help direct water through the landscape rather than allowing it to sit in low areas.

Rock can play both a functional and visual role. Colorado Materials' cobble stones, for example, are well suited for dry creek beds and drainage swales, while several of its river rock products can work in drainage areas while creating a natural finished look.

Good drainage starts with knowing where the water needs to go.

The part of your patio you never see may be one of the most important parts of the project.

A beautiful paver or stone surface needs a properly prepared foundation beneath it. Compactable base materials create a stable layer that helps support the finished hardscape.

Colorado Materials' Class 6 Road Base is designed as a stable, compactable foundation for pavers, concrete, and asphalt installations. We also stock washed sand, breeze, pavers, flagstone, and other materials for hardscape projects.

The finished patio gets all the attention. The base underneath helps it do its job.

Before ordering material, three measurements can save you a lot of guesswork:

Length. Width. Depth.

It's easy to focus on the square footage of a project and forget that installation depth affects how much material you'll actually need.

Colorado Materials' Material Calculator makes the next step easy. Choose your material, enter your measurements, and estimate the quantity required for rectangular, circular, or triangular areas.

Have an unusual project? You can also call the team with your dimensions for help estimating your order.

A few minutes with a tape measure now can make ordering day much easier.

Rock or mulch? Sometimes the answer is both.

Combining materials can add contrast, texture, and definition to a landscape while allowing each material to serve a different purpose.

Decorative rock can create durable ground cover, borders, pathways, and accents, while mulch works beautifully around plantings and helps retain moisture, regulate soil temperature, and suppress weeds.

Colorado Materials carries everything from neutral 3/8" Grand Mesa Gray and smooth river rocks to cedar, shredded, and colored mulches, making it easy to build a landscape with more than one texture.

A yard and a ton aren't the same thing.

A cubic yard measures volume, or how much space a material takes up. A ton measures weight.

That distinction matters because different landscape materials have different densities. A cubic yard of mulch doesn't weigh the same as a cubic yard of rock, and even different aggregates can vary.

That's why estimating materials isn't always as simple as deciding how many "yards" you need.

Colorado Materials' online Material Calculator lets you enter your material type along with your project's dimensions and depth to help estimate what you'll need. It also includes a Material Conversion tool.

Measure first. Calculate second. Order with a little more confidence.
