Waterproofing in Mallorca is a critical element in the design and execution of any construction project, whether new build or refurbishment. Due to the island’s Mediterranean climate—with humid winters, occasional torrential rainfall, and high salinity in coastal areas—buildings are particularly vulnerable to leaks, condensation, and premature material degradation.

In this article, we explain why high-quality waterproofing systems are essential, which technical solutions Polivas offers, and the key factors architects and contractors should consider to ensure long-lasting and safe results.

Why is Waterproofing Essential in Mallorca?

Mallorca presents a combination of climatic conditions that make professional waterproofing indispensable:

  • High humidity and seasonal rainfall, which often lead to leaks in poorly protected roofs, terraces and basements.

  • Exposure to salt in coastal areas, which accelerates the deterioration of materials without impermeable barriers.

  • High summer temperatures, requiring systems resistant to extreme thermal cycles and UV radiation.

The consequences of poor waterproofing are not merely aesthetic—it can affect the structure, reduce energy efficiency, and lead to significant maintenance costs in the medium term.

Waterproofing Solutions in Mallorca with Polivas

At Polivas, we offer professional waterproofing solutions tailored to each type of structure, project and regulatory requirement. We work with leading manufacturers such as Danosa, Soprema, Onduline, and Impertek, ensuring cutting-edge products for every application.

1. Bituminous Membranes and Double-Layer Systems

A traditional, high-resistance system for flat roofs, walkable terraces and rooftops. The double-layer application reinforced with polyester mesh offers outstanding durability against standing water, weather exposure and mechanical stress.

2. Synthetic Membranes (PVC, TPO, EPDM)

A modern, flexible solution for industrial roofs, green roofs and surfaces with complex geometries. These membranes offer long life, hot-air weldability, superior elasticity, and excellent chemical resistance.

3. Liquid Waterproofing

Continuous coatings applied on-site—ideal for refurbishment or irregular surfaces. Based on polyurethane, polyurea, or acrylic resins, these systems offer strong adhesion and fast drying.

4. Drainage Systems and Geotextiles

These systems complement waterproofing in green roofs, retaining walls, and basements by preventing water build-up and protecting the waterproofing layer from soil pressure.

Technical Recommendations for Architects and Contractors

Professionals in the construction sector should take the following factors into account when planning a waterproofing strategy:

  • Location and use of the area (walkable roof, terrace, basement, external wall).

  • Slope and water drainage, to prevent ponding.

  • Compatibility between support materials and waterproofing systems.

  • Applicable regulations, such as Spain’s CTE DB-HS1 (Health and Hygiene) and DB-SE-C (Foundations).

  • Manufacturer guidelines and certified installation, to ensure long-term performance and warranty validity.

In sustainable building projects or those pursuing Passivhaus standards, waterproofing also plays a crucial role in airtightness, improving the building’s energy efficiency.

Application Cases in Mallorca

At Polivas, we have taken part in numerous waterproofing projects in Mallorca, from residential buildings to hotels, commercial spaces and industrial units. Our experience includes:

  • Walkable attic roofs with Soprema double-layer membranes.

  • Basement waterproofing using drainage membranes and geotextiles.

  • Façade protection with water-repellent systems and breathable membranes.

  • Pitched roofs waterproofed with Onduline systems.

Each project is assessed by our technical team to provide a bespoke solution tailored to the environment, intended use, and client budget.

Conclusion

Waterproofing in Mallorca requires technical solutions adapted to the local climate, building typology, and current regulations. Choosing the right system not only protects the structure, but also extends its lifespan, lowers maintenance costs, and enhances indoor comfort.

At Polivas, we specialise in high-quality waterproofing solutions for all types of projects across the island. We support you from system selection to installation, working exclusively with top-grade materials.
