Can you build bricks on an EPDM tarpaulin?

EPDM (ethylene propylene diene monomer) is an increasingly popular material in the waterproofing field, particularly for roofs, pools and terraces. Its strength and durability make it a preferred choice for many projects.

However, a question often arises: is it possible to mason directly on an EPDM sheet? This article explores the possibilities and precautions to take when considering masonry on this type of material.

What is EPDM?

EPDM is a synthetic rubber, known for its high resistance to UV, weathering and many chemicals. It is widely used for waterproofing flat roofs, pools and terraces. Its durability and flexibility make it an ideal material for many outdoor applications.

Masonry and EPDM - Compatibility

Masonry directly onto EPDM sheeting presents challenges. The main risk is perforation or collapse of the material under the weight of the masonry. It is crucial to understand that while EPDM is strong, it is not designed to support heavy loads without proper preparation.

Precautions and Techniques for Masonry on EPDM

Before starting the masonry, it is essential to prepare the surface of the EPDM. This may involve installing a protective layer or a drainage system under the sheeting. When masonry, it is recommended to use techniques that distribute the weight evenly and to be careful not to puncture the membrane. Alternatives, such as building a separate load-bearing structure on top of the EPDM, can also be considered.

Expert Advice and Best Practices

Construction and waterproofing experts suggest consulting a professional before undertaking such work. They also recommend considering case studies where similar projects have been successfully completed. Using materials that are compatible with EPDM and following the manufacturer's specifications are crucial to the success of the project.

Conclusion

Although bricklaying on EPDM sheeting is technically possible, it requires careful planning and execution. By taking into account expert advice and following best practices, it is possible to achieve a durable and safe project, while preserving the integrity of the EPDM.
