Provoid is a high-performance gas venting and protection system designed to manage and safely disperse harmful ground gases, such as methane, carbon dioxide, and radon, from beneath buildings. This system effectively channels gases away from the building structure, reducing the risk of gas accumulation and ensuring a safe indoor environment. Provoid is easy to install, making it suitable for a wide range of construction projects, including residential, commercial, and industrial buildings. Its robust and durable design ensures long-term performance, helping to meet stringent building regulations and standards for gas protection. Provoid is an ideal solution for projects where effective gas management is critical for safety and compliance.

• How does Provoid contribute to gas protection? - Provoid works by creating a void beneath the building floor, which serves as a ventilation channel. This channel allows harmful gases to be safely vented away from the structure, reducing the risk of gas accumulation inside the building and protecting occupants' health and safety.
• How is Provoid installed? - Provoid is installed by laying out the void former units in a grid pattern beneath the building floor, typically over a gas-resistant membrane. The units are connected to form a continuous void, and air bricks or vent stacks are used to facilitate ventilation. The system is covered with a concrete or screed floor slab to provide structural support.
• Is Provoid environmentally friendly? - Provoid helps maintain indoor air quality by safely venting hazardous gases away from building occupants. Its use can contribute to healthier living and working environments, making it a part of sustainable construction practices.
