Construction sites are notoriously rugged, so the products needed for materials storage must be resilient and durable. Bulk bags, also known as flexible intermediate bulk containers (FIBCs) are often used on construction sites to store sand, cement, rubble and gravel. These bulk packaging containers need to be able to withstand the tough environment and keep the stored materials safely contained.

Construction companies and contractors should choose high-quality FIBCs from a reputable supplier. Not all bulk bags are designed for the conditions on construction sites, so you’ll need to consult with your supplier before placing an order.

Custom Bulk Bags is a manufacturer and supplier of world-class bulk bags in South Africa. We produce up to 3.5 million FIBCs per year. All of our products have a minimum safety factor rating of 5:1 and are manufactured in accordance with international regulations and standards.

Challenges on construction sites

Construction sites are busy and dynamic spaces filled with heavy machinery and rough terrain. This has a real impact on packaging products used to store raw materials. The machinery used to move bulk bags could puncture the fabric; chemical contamination is a possibility on-site; exposure to water and sunlight could affect the raw materials and the FIBCs themselves. 

All of these factors need to be considered and processes put in place to minimise the various risks. The integrity of the FIBCs is crucial for employee safety and a smooth operation. 

To ensure that contractors get the most out of their packaging products, it’s important to work with a bulk bag manufacturer that can guarantee the durability and quality of their products. Custom Bulk Bags uses extruded polypropylene tapes to weave the fabric exterior of its FIBCs. These tapes are extruded by our sister company, Integrated Polypropylene Products (IPP) from high-quality raw materials.

What to consider for construction bulk bags

Bulk bags are highly customisable with various optional extras available to suit your specific requirements. When it comes to FIBCs for construction, quality and durability are the two most important factors. These ensure the proper performance of the FIBC and their ability to safely store various materials as expected.

Bags made from high-quality polypropylene are extremely durable and tear-resistant. This provides superior protection against wear and tear, moisture ingress and the elements present at a construction site. Additional UV-resistant coatings are highly recommended for the external fabric of the bulk bags to prevent the sun from damaging them.

Be sure to choose a higher weight of fabric as these are more durable. Our consultants are always available to guide you through the options and to give you advice that will improve the durability of your FIBCs. They can also assist you with choosing the correct bag style, lifting loops and attachments that will improve the FIBCs efficiency and effectiveness on-site.

Remember to let us know if your bulk bags will be stored under a cover or out in the open as this will change the necessary design and the need for additional coatings or inner liners. While UV coatings are recommended for bulk bags that are used outdoors, such as on a construction site, if they are stored under a cover then it means that a lesser coating will be required.

Consulting with an expert will allow you to get more value out of your bulk bags. The improved quality of your products will certainly pay off, as well as ensure the safety of your employees on-site. For more information about our bulk bags, please contact us today.
