About Our Paver Sand Calculator
Our Paver Sand Calculator is a valuable tool for homeowners, contractors, and landscapers planning paver installation projects. It accurately estimates the amount of sand needed for both the base layer and the joints between pavers, helping you purchase the right amount of materials and avoid costly overages or shortages.
Types of Sand Used in Paver Projects
Paver projects typically require two types of sand:
- Base Sand: Also called bedding sand, this creates a level surface for placing pavers. Typically, concrete sand or mason sand is used for this purpose.
- Joint Sand: This fills the gaps between pavers. It can be regular sand or polymeric sand, which hardens when wet to create more stable joints and prevent weed growth.
How We Calculate Sand Requirements
Our calculator uses the following formulas:
Base Sand Volume:
Area (sq ft) × Sand Depth (ft) = Volume (cubic ft)
Joint Sand Volume:
Joint Area × Paver Depth = Volume
Where Joint Area = Total Area - Area Covered by Pavers
The calculator converts cubic feet to cubic yards and also provides an estimate in tons based on the typical weight of sand.
Key Features:
- Calculate both base sand and joint sand requirements
- Account for different paver sizes and joint widths
- Convert measurements to both cubic yards and tons
- User-friendly interface with intuitive inputs
- Automatic calculations with no manual conversions required
How to Use:
- Enter the length and width of your paver area in feet
- Specify the depth of base sand layer in inches (typically 1" for patios and walkways)
- Enter the joint width between pavers in inches (typically 1/8" to 1/4")
- Input your paver dimensions (width, length, and depth in inches)
- Click "Calculate Sand Requirements" to see the results
Tips for Successful Paver Installation:
Proper Base Preparation: In addition to sand, most paver projects require a base layer of gravel or crushed stone (typically 4-6 inches).
Compaction: Both the gravel base and sand layer should be properly compacted before laying pavers.
Slope Considerations: Incorporate a slight slope (about 1/4 inch per foot) away from buildings for proper drainage.
Edge Restraints: Install edge restraints to prevent pavers from shifting over time.
Purchasing Materials: Add 5-10% to your calculated amounts to account for waste, spillage, and settling.
Base Material vs. Sand
Note that this calculator focuses only on the sand requirements. For a complete paver project, you'll also need:
- Base Material: Usually 4-6 inches of compacted gravel or crushed stone beneath the sand layer
- Edge Restraints: To keep pavers from shifting
- Landscape Fabric: Optional weed barrier between soil and base material
- Pavers: The actual paving stones for your project
Whether you're installing a patio, walkway, driveway, or pool deck, our Paver Sand Calculator helps ensure you purchase the right amount of sand for a professional-looking finished project.
Frequently Asked Questions
What type of sand should I use for paver base and joints?
For the base layer, concrete sand (also called mason sand) is typically recommended as it provides good drainage and compacts well. For joints, you can use fine sand or polymeric sand. Polymeric sand contains additives that harden when activated with water, creating more stable joints that resist erosion, inhibit weed growth, and deter insects. The choice depends on your budget, project requirements, and local availability.
How does sand weight convert to bags for purchase?
Sand is typically sold in 50-pound bags, cubic yard bulk quantities, or by the ton. One ton of sand is approximately 2,000 pounds, which equals about 40 standard 50-pound bags. One cubic yard of sand weighs approximately 2,700 pounds (1.35 tons). For smaller projects, calculate the number of bags needed by dividing your required weight by 50 pounds. For larger projects, ordering by the cubic yard or ton from a landscape supply company may be more economical.
Do I need to add extra sand to account for waste or settling?
Yes, it's generally recommended to add 5-10% to your calculated amounts to account for waste, spillage, compaction, and settling. For base sand, additional material may be needed to account for uneven ground or to achieve proper slope for drainage. For joint sand, you might need extra if you're using it on a large project or if the pavers have irregular edges that create wider joints in some areas.
