Premium Aggregates Available for Ontario Delivery
We maintain a comprehensive inventory of gravel, stone, and aggregate products suited for the Inland Empire's construction demands. Ontario's position as a major logistics hub means we can efficiently source and deliver materials throughout San Bernardino County and beyond.
Crushed Stone and Gravel Products
Crushed stone forms the foundation of most construction projects in Ontario. Our 3/4 inch crushed stone remains the most popular choice for homeowners in Armstrong Park and Mountain Vista areas. This versatile aggregate compacts well and provides excellent drainage for the region's occasional heavy winter rains.
For projects requiring stronger interlocking capability, our #57 stone delivers superior performance. This angular aggregate works exceptionally well for foundation bases in Ontario's expansive clay soils, which can shift during seasonal moisture changes.
- Crushed Stone 3/4 inch - Ideal for driveways and base layers throughout Ontario
- #57 Stone - Angular aggregate perfect for drainage applications
- Crusher Run - Mixed aggregate with fines for maximum compaction
- Road Base - Heavy-duty foundation material for parking areas
- Drain Rock - Clean aggregate for French drains and septic systems
The crusher run we supply contains a blend of stone and fines that creates an incredibly stable base. Contractors in the Vineyard neighborhood and throughout South Ontario rely on this product for commercial parking lots and warehouse access roads.
Decorative Stone and Rock
Ontario's year-round sunshine makes outdoor living spaces essential. Decorative aggregates transform backyards into beautiful retreats while reducing water usage in compliance with local conservation guidelines.
Our river rock comes in multiple sizes to suit any aesthetic preference. Homeowners in the De Anza Park area frequently use larger river rock around drought-tolerant plants, creating stunning low-maintenance gardens that thrive in Ontario's semi-arid climate.
Pea gravel offers a softer alternative for high-traffic areas. The smooth, rounded stones feel comfortable underfoot and work beautifully around patios in the Bon View area. This aggregate also provides excellent drainage, preventing water pooling during Ontario's winter rain season.
For authentic Southwestern charm, decomposed granite creates natural-looking pathways and xeriscaped areas. This material compacts firmly while maintaining permeability, making it perfect for Ontario's Model Colony historic district where preserving neighborhood character matters.
Functional Gravels for Driveways and Walkways
Your driveway endures daily punishment from vehicles, weather, and foot traffic. Selecting the right aggregate ensures longevity and curb appeal for your Ontario property.
Our driveway gravel combines durability with attractive appearance. This carefully graded material compacts tightly to resist rutting while allowing proper drainage. Homes in Ontario's Edenglen neighborhood benefit particularly from this product, as the area's gentle slopes require materials that stay in place during rainstorms.
For pedestrian pathways, our walkway gravel provides a comfortable walking surface that complements any landscape design. The Cucamonga-Guasti Regional Park area inspires many Ontario residents to create meandering garden paths, and this aggregate delivers the perfect texture and stability.
Soil and Fill Materials
Quality soil products complete any landscaping or construction project. Ontario's native soils often require amendment or supplementation for optimal results.
Our topsoil contains rich organic matter essential for healthy plant growth. Gardeners establishing lawns and flower beds in the College Park neighborhood depend on premium topsoil to overcome the region's naturally alkaline soil conditions.
For grading and leveling applications, our fill dirt provides economical volume without unnecessary organic content. Construction projects near the Ontario Mills area frequently require substantial fill to prepare sites for foundations and parking structures.
Sustainable Aggregate Options
Environmental responsibility matters to Ontario residents. Our crushed concrete offers an eco-friendly alternative that performs comparably to virgin aggregates. This recycled material works exceptionally well for base layers and drainage applications throughout the Inland Empire.
Using recycled aggregates reduces landfill burden while decreasing demand for quarried materials. Contractors working on LEED-certified projects near Ontario's downtown revitalization areas increasingly specify crushed concrete for its environmental benefits.
Sand Products for Every Application
We supply multiple sand varieties to meet diverse project requirements throughout Ontario and San Bernardino County.
Mason sand provides the fine, consistent texture required for mortar mixing and brick laying. Block wall construction remains popular in Ontario for security and noise reduction, making quality mason sand essential for local masons.
For family-friendly applications, our playground sand meets safety standards for play areas. Ontario's numerous community parks and residential developments prioritize child safety, and our sand provides the soft, clean surface parents expect.
Our washed sand serves versatile purposes from concrete mixing to pipe bedding. This thoroughly cleaned aggregate ensures optimal performance in demanding construction applications throughout the Inland Empire.
Choosing the Right Aggregate for Ontario Projects
Understanding which material suits your specific application saves time and money. The following comparison helps Ontario property owners and contractors make informed decisions.
| Material Type | Best Applications | Drainage Rating | Heat Reflection | Compaction |
|---|---|---|---|---|
| Crushed Stone 3/4 inch | Driveways, foundations, base layers | Excellent | Moderate | Excellent |
| #57 Stone | Drainage, pipe bedding, French drains | Excellent | Moderate | Good |
| Pea Gravel | Pathways, patios, decorative beds | Excellent | Good | Poor |
| Decomposed Granite | Walkways, xeriscaping, natural areas | Good | Excellent | Good |
| Crusher Run | Road base, parking areas, heavy traffic | Good | Moderate | Excellent |
| River Rock | Decorative landscaping, dry creek beds | Excellent | Good | Poor |
| Road Base | Commercial driveways, foundation prep | Moderate | Moderate | Excellent |
| Drain Rock | French drains, septic systems | Excellent | Good | Poor |
Ontario's average summer temperatures exceed 90 degrees Fahrenheit, making heat reflection an important consideration for walkways and patios. Lighter materials like decomposed granite and light-colored pea gravel stay cooler underfoot during peak afternoon hours.
The region receives approximately 15 inches of annual rainfall, primarily between November and March. Selecting materials with excellent drainage prevents water damage and erosion during intense winter storms that occasionally impact the Inland Empire.
Common Aggregate Applications in Ontario
Residential Driveway Projects
Ontario's diverse housing stock presents varied driveway requirements. Older homes in the Central City West neighborhood often feature shorter driveways that benefit from decorative aggregate surfaces. Newer developments in Ontario Ranch typically require more substantial gravel foundations to support multiple vehicles.
A proper driveway installation begins with compacted road base material, typically 4-6 inches deep. This creates a stable foundation that resists the settling common in Ontario's clay soils. Top this with your choice of decorative gravel or additional crushed stone for a finished surface that performs beautifully for years.
Drainage Solutions
Despite Ontario's generally dry climate, proper drainage remains critical. The Santa Ana winds can deposit significant debris that clogs inadequate drainage systems. French drains lined with drain rock protect foundations throughout the Patterson and Virginia neighborhoods where homes sit on slight grades.
Commercial properties near Ontario International Airport require robust drainage to manage runoff from large paved surfaces. Our drain rock and #57 stone provide the percolation rates necessary for compliance with local stormwater management regulations.
Xeriscaping and Water Conservation
Water conservation has become essential throughout Southern California. Ontario residents increasingly replace thirsty lawns with attractive xeriscaped designs featuring drought-tolerant plants surrounded by decorative aggregates.
Decomposed granite creates permeable surfaces that allow rainwater infiltration while requiring zero irrigation. River rock adds visual interest and helps retain soil moisture around established plantings. These materials align with Gravel Monkey's commitment to sustainable landscaping solutions.
Commercial and Industrial Projects
Ontario's position as a logistics hub creates constant demand for commercial aggregate applications. Warehouse facilities, distribution centers, and manufacturing plants require durable parking surfaces and access roads capable of handling heavy truck traffic.
Crusher run and road base materials provide the load-bearing capacity these applications demand. Our bulk delivery capabilities serve contractors working on projects throughout the Ontario business corridors, from Fourth Street to the I-10 industrial areas.

Understanding Ontario's Unique Conditions
Soil and Geology
Ontario sits on the alluvial plain formed by Cucamonga Creek and other waterways flowing from the San Gabriel Mountains. This geological history created soils containing significant clay content mixed with sand and gravel deposits.
The expansive clay common throughout the region swells when wet and shrinks during dry periods. This movement can crack foundations and heave concrete slabs if proper base preparation is neglected. Using crusher run or road base beneath hardscape installations creates a stable buffer that accommodates soil movement.
Climate Considerations
Ontario experiences a Mediterranean climate characterized by hot, dry summers and mild, wet winters. Average high temperatures exceed 90 degrees from June through September, while winter lows rarely drop below 40 degrees.
This climate profile influences aggregate selection significantly. Materials exposed to direct sunlight should be lighter in color to reduce heat absorption. Proper drainage preparation remains essential despite limited annual rainfall, as winter storms can deliver several inches of rain within short periods.
The Santa Ana winds that periodically sweep through the Inland Empire create additional considerations. Finer materials like decomposed granite should be well-compacted to prevent wind erosion, while larger aggregates like river rock remain stable regardless of wind conditions.
Local Regulations
Ontario's commitment to sustainable development influences landscaping choices. The city encourages water-efficient landscapes through various incentive programs. Using aggregates to reduce irrigated lawn areas aligns with these community goals while reducing long-term maintenance requirements.
Commercial projects near the airport must meet specific stormwater management requirements. Permeable aggregate installations can help meet these regulations while providing attractive, functional surfaces.
