Builders’ bags are one of the most widely used bulk packaging solutions in the construction industry. Designed to safely transport and store aggregates, sand, gravel, topsoil and waste materials, they provide a reliable and cost-effective solution for projects of all sizes. This guide explains the different types of builders’ bags, their common applications, safe working loads and how to choose the right bag for your business.
What is a Builders’ Bag?
A builders’ bag is a heavy-duty woven polypropylene bulk bag designed to transport and store loose construction materials safely. Often referred to as a bulk bag, jumbo bag or dumpy bag, builders’ bags are commonly used for aggregates, sand, gravel, topsoil, rubble and waste. They are fitted with strong lifting loops for safe handling using forklifts or cranes.

Builders’ Bag Sizes and Safe Working Loads
Builders’ bags are available in a range of sizes and Safe Working Loads (SWL) to suit different applications. Choosing the correct bag helps ensure safe handling and efficient transport.
Typical specifications include:

- 1000 kg (1 tonne) – The most common builders’ bag for construction and aggregates.

Always ensure the bag’s Safe Working Load (SWL) and Safety Factor (SF) are suitable for your intended application.
Bulk bags should always be lifted using the correct equipment and within their rated Safe Working Load. Before each use, inspect the bag for damage to lifting loops, seams and fabric. Never exceed the manufacturer’s recommended load capacity, and always follow safe lifting procedures to protect operators and materials.
