Can you build bricks on an EPDM tarpaulin?

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

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

What is EPDM?

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

Masonry and EPDM - Compatibility

Building masonry directly on an EPDM liner presents challenges. The main risk is the perforation or sagging of the material under the weight of the masonry. It is crucial to understand that, although EPDM is strong, it is not designed to support heavy loads without proper preparation.

Precautions and Masonry Techniques on EPDM

Before starting the masonry, it is essential to prepare the EPDM surface. This may involve installing a protective layer or a drainage system beneath the liner. When building the masonry, it is recommended to use techniques that distribute the weight evenly and to ensure that the membrane is not punctured. Alternatives, such as building a separate load-bearing structure on 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 compatible with EPDM and following the manufacturer's specifications are crucial for the success of the project.

Conclusion

Although building masonry on an EPDM liner is technically possible, it requires meticulous planning and careful execution. By taking expert advice into account and following best practices, it is possible to complete a durable and secure project while preserving the integrity of the EPDM.
