Handling large volumes of aggregates, debris, or granular materials on-site requires a bag that fills quickly and can withstand the strain without bursting. This open-top, flat-bottom big bag—also called a super sack or FIBC—is manufactured by Fortemo from professional-grade woven polypropylene, with a 5:1 safety factor, and designed for intensive operations in civil construction, agroindustry, and recycling in the Dominican Republic.
Key benefits
- Unrestricted filling: The full opening allows for unloading shovels, hoppers, conveyors, or bulky products without jams or bottlenecks on-site.
- Stability at rest: Flat bottom keeps the bag upright during filling and allows it to be stacked on pallets without tipping over.
- Generous payload: 1500 kg maximum working load with a 5:1 safety factor, sized for dense aggregates such as sand, gravel, or wet debris.
- Careful manufacturing: Virgin polypropylene fabric with reinforced handles and industrial stitching in stress areas, designed to withstand repeated lifting with a crane or forklift.
- Standard dimension 90×90×100 cm: Fits on a 1.0 m × 1.2 m pallet and allows for organized stacking in a warehouse or on a construction truck.
Typical applications and uses
- Collection and removal of debris in remodels, controlled demolitions, and renovations.
- Storage and transport of aggregates (sand, gravel, crushed stone) in civil construction projects.
- Handling of agro-industrial products: grains, seeds, fertilizers, and animal raw materials.
- Temporary storage of biomass, husks, cinders, or vegetable waste.
Quality and durability
Fortemo works with virgin polypropylene and reinforced industrial stitching in critical areas (handles, base, corners). Under the Caribbean sun, a low-cost bag loses structural strength in a few weeks; this model maintains fabric integrity during several cycles of reasonable outdoor use. The difference between a premium big bag and a generic one is noticeable the first time you load 1500 kg of wet gravel and lift it with a crane: if the bag holds, you haven't lost a day's work.
Yes — it handles wet materials without issue within its rated capacity. Woven polypropylene is hydrophobic and does not absorb water, so wet sand, gravel after rain, saturated rubble or wet soil do not affect the sack's integrity. What does change is weight: a cubic meter of wet sand weighs more than dry, so control filling to avoid exceeding the 1500 kg maximum working load.
The difference is in the polypropylene and the seams. A budget sack is made with recycled resins, low weight per square meter and simple seams; under heavy aggregate loads, the loops give and the base deforms. This big bag uses virgin polypropylene, reinforced industrial seams on loops and base, and a 5:1 safety factor verified by the manufacturer. It's the difference between a single-use sack and one that holds up across several construction cycles.
For bulk grain destined for further processing (animal feed, seed, industrial raw material), yes it is suitable. For direct contact with finished human food, the model with internal liner is preferable, since it isolates the contents from the outer fabric and blocks ambient dust. This model comes without liner and is intended for aggregates, rubble and agro-industrial product where direct contact with the fabric does not compromise the final use of the material.
