Estimate the required amount of hot-pour or cold-pour sealant for your pavement repair project.
The calculator uses two primary methods for estimation:
For 500 ft of cracks at 0.5 in wide and 0.5 in deep with a 15% waste factor:
The Crack Filler Calculator is a professional-grade tool designed for contractors, maintenance crews, and property owners to accurately budget and plan for pavement crack sealing projects. It eliminates the guesswork inherent in traditional estimation methods by providing a data-driven approach to material calculation. Whether you are using hot-pour solid blocks or cold-pour liquid emulsions, this calculator ensures you purchase the correct amount of material, preventing costly over-ordering or frustrating mid-project shortages.
A key feature of the Crack Filler Calculator is its dual-mode functionality. The "Detailed" mode allows for precise calculations based on measured crack dimensions (length, width, and depth), making it ideal for projects where accuracy is paramount. For quick budgeting or when detailed measurements are not available, the "Simplified" mode provides a reliable estimate based on total crack length and industry-standard dimensions (1/2" x 1/2"). This flexibility makes the tool adaptable to any phase of a project, from initial bidding to final procurement.
The logic embedded in the Crack Filler Calculator is based on established industry standards and technical data. The default waste factor of 15% aligns with recommendations from the Federal Highway Administration (FHWA), accounting for material loss and best-practice overbanding. Furthermore, the calculator's internal density and coverage rates are synthesized from the technical data sheets of leading sealant manufacturers. This ensures the outputs are not just theoretical but reflect real-world material properties and application scenarios. For a deeper dive into the materials, Wikipedia's article on Asphalt Emulsion provides a good background on cold-pour products.
Ultimately, the Crack Filler Calculator does more than just calculate numbers; it promotes better project outcomes. By converting the final required quantity into common package sizes (e.g., 5-gallon pails, 30-lb blocks), it creates a practical "shopping list" that simplifies the ordering process. It also incorporates a critical application guideline, reminding users that cracks deeper than 1/2 inch should be filled with sand or backer rod first. This guidance helps prevent sealant failure and ensures a long-lasting, cost-effective repair. Using the Crack Filler Calculator empowers you to manage your crack sealing projects with greater confidence and efficiency.

This value is based on guidance from the Federal Highway Administration (FHWA) for crack sealing projects. It accounts for material left in containers, minor spills, and the small amount of extra material used for "overbanding" (applying a thin layer over the crack edges) to create a better seal.
"Detailed" mode provides the most accurate estimate by calculating the precise volume from the length, width, and depth you provide. "Simplified" mode is for quick estimates when you only know the total length; it assumes a standard crack size of 1/2 inch by 1/2 inch.
Industry best practice dictates that sealant in deep cracks should not be more than 1/2 inch thick to function properly. Cracks deeper than 1/2 inch must first be filled with sand or a foam backer rod to within 1/2 inch of the pavement surface before applying the sealant. This saves money and prevents repair failure.
Hot-pour, rubberized sealants are generally more durable and flexible, making them ideal for high-traffic areas and climates with large temperature swings. Cold-pour sealants are easier to apply (no special heating equipment needed) and are suitable for driveways, parking lots, and smaller repair jobs.
