Building Materials Bulk Bags

Durable FIBCs for Transporting Sand, Gravel, Cement, and Construction Materials 

Bulk bags (FIBCs) are essential for efficiently transporting and storing building materials, especially when it comes to high-volume loads of masonry sand.  At FlexSack, we specialize in creating building materials FIBCs that deliver durability, protection, and convenience; all while helping you streamline your operation.  Whether you’re dealing with masonry sand, aggregates, or other construction essentials, our goal is to provide reliable bulk bag solutions to keep your projects moving smoothly. 

Types of Building Materials Commonly Transported

in Bulk Bags 

Proper handling of construction materials is critical to efficiency, safety, and cost control. FlexSack’s high-performance FIBCs (Flexible Intermediate Bulk Containers) are engineered to meet the diverse needs of the building materials industry. Whether you’re transporting loose-fill aggregates or fibrous ground cover, we offer bulk bag solutions tailored to your product type and handling requirements. 

Common building materials transported in FlexSack bulk bags include: 

• Masonry Sand: Vital for mortar and concrete mixes, requiring moisture-resistant packaging to prevent clumping. 

• Gravel & Aggregates: Heavier, rugged materials used in construction and landscaping. Require durable, puncture-resistant bags. 

• Cement & Powders: Fine, airborne materials needing dust-proof containment with tight sealing. 

• Stone & Stone Chips: Irregular and sharp-edged, best handled with reinforced and stackable FIBCs. 

• Pre-Form Rebar: Pre-shaped steel reinforcement bars benefit from bundling solutions that prevent shifting during transit. 

• Sports Turf Infill, Mulch & Pine Bark: Lightweight and breathable materials needing ventilated bags to prevent mold and maintain freshness. 

• Bulk Pine Straw: High-volume landscaping product that requires compression-friendly packaging for efficient shipping. 

• Firewood: Needs containment that prevents debris while allowing easy stacking and distribution. 

• Concrete Washout Containment: Leftover slurry and debris from cleaning concrete mixers must be stored in leak-proof, durable bags. 

• Garden, Planter Bed, and Rooftop Soil Mix: Requires packaging that retains moisture while preventing leakage or contamination.

“We were using one of their competitors here in town and I’ll be honest with you—before Brian came here, we looked at those sacks as just a commodity. Our decisions were based purely on price. But when Brian came in, he asked questions that no one had ever asked me before. Honestly, some of the things he got me thinking about—I had never even considered.”
