Ground gas protection
Ground gas protection, particularly against radon, hydrocarbons, and methane, involves the implementation of specialized measures to prevent the ingress of these harmful gases into buildings and structures. This typically includes the installation of gas-resistant membranes, barriers, and ventilation systems to mitigate the potential risks associated with these gases. Radon, a radioactive gas, is often mitigated through the use of radon barriers and ventilation systems. Hydrocarbons and methane, which can pose explosion and health risks, are addressed through the installation of hydrocarbon barriers and methane mitigation systems. These protective measures are essential for ensuring the safety and structural integrity of buildings in areas affected by these ground gases.
Sheet and liquid applied membranes
Ground gas protection using sheet membranes or liquid applied membranes involves the installation of specialized barriers to prevent the ingress of harmful gases such as radon, hydrocarbons, and methane into buildings and structures.
Sheet membranes: These are pre-fabricated membranes that are installed to create a physical barrier against ground gases. They are commonly used in below-grade applications, such as basements and foundations, to provide a continuous and durable protection layer. Sheet membranes offer a reliable and robust solution for ground gas protection, particularly in areas with high levels of gas permeability.
Liquid applied membranes: These membranes are coatings that are directly applied to surfaces to create a seamless and flexible barrier against ground gases. Liquid applied membranes offer versatility in application, conforming to complex geometries and detailing, making them suitable for various substrates and construction conditions. They provide an effective and adaptable solution for ground gas protection, particularly in areas where traditional sheet membranes may be challenging to install.
Both sheet membranes and liquid applied membranes play a critical role in safeguarding buildings and structures from the potential risks associated with ground gases, ensuring the safety and longevity of the built environment.
