Evolution in the construction industry has led to the development of innovative solutions to ensure energy efficiency and durability of structures. One such solution is gravel-ballasted flat roofs, which find ideal implementation in combination with EPDM waterproofing membranes Hidrostan. This technology offers numerous advantages not only in terms of climatic and economic performance, but also in terms of environmental impact, a key aspect of sustainable development.

Benefits of Flat Roofs Ballasted with Gravel

Impermeable EPDMmembranes Hidrostan are renowned for their excellent water, chemical and UV resistance. Combining them with gravel as ballast further enhances waterproofing, protecting the membrane from weathering and mechanical damage, and provides a service life that can exceed 50 years due to their ozone resistance and ability to maintain elasticity over a wide temperature range. Gravel adds an additional protective layer, reducing the membrane's direct exposure to external agents.

In cold climates, roofs ballasted with gravel and EPDM membranes Hidrostan are ideal for preventing snow and ice accumulation, reducing structural damage caused by weight and uneven melting. Gravel promotes efficient drainage, preventing puddles and water infiltration, while in warm environments, gravel helps reflect some of the sun's heat, helping to keep the roof surface temperature lower. This not only improves indoor comfort, but also reduces thermal stress on the membrane, prolonging its service life.

The gravel acts as ballast, stabilizing the waterproof membrane and reducing the risk of wind uplift. This is especially important.

Gravel-ballasted roofs improve the building's thermal insulation, helping to reduce temperature fluctuations and maintain a constant indoor temperature.

With improved energy efficiency, gravel-ballasted flat roofs help reduce energy consumption for heating and cooling, lowering the building's CO2 emissions. In urban areas, gravel roofs help reduce ambient temperature by counteracting the heat island effect. This effect results in less use of cooling systems, further saving energy and reducing greenhouse gas emissions.
