What are the materials used for keeping concrete elements from touching each other during storage called?

Dunnage refers to the materials used to support and keep concrete elements separated during storage and transportation. It is crucial in preventing concrete elements from touching each other, which can lead to damage such as chipping or cracking. Dunnage typically consists of wooden blocks, pallets, or other materials that provide a stable foundation and maintain spacing between the elements, ensuring proper air circulation and facilitating easier handling.

In construction and storage practices, maintaining a safe distance between concrete elements is vital for preserving their integrity until they are ready for use. The use of dunnage not only protects the items but also allows for organized storage and easier access to individual pieces.

Formwork, shims, and rebar serve different purposes in construction. Formwork is used to shape and support wet concrete until it hardens, shims are small pieces of material used for leveling or providing support, and rebar is reinforcement material incorporated into concrete to enhance its strength. None of these functions directly relate to the role of maintaining separation during storage like dunnage does.
