INTERBETON, a member of the TITAN Group, develops concrete solutions that meet the highest performance standards of today and tomorrow. Guided by sustainability and technological innovation, it creates solutions that improve the quality, safety, and long-term performance of construction projects.
ENVIRA is an innovative permeable ready-mix concrete, designed for outdoor cast-in-place pavements. Its porous structure—achieved through carefully graded aggregates, cement, specialized admixtures, and water—allows water to pass through its mass, reducing flood risk and lowering the thermal load of urban surfaces. It offers environmental and functional benefits, making it an excellent choice for sustainable urban infrastructure. ENVIRA has a VESTA™ A rating, confirming its outstanding environmental performance.
ENVIRA is an ideal solution for managing stormwater runoff, as its composition significantly reduces the hydrological and thermal load on urban infrastructure. Compared with conventional materials such as asphalt, ENVIRA supports environmental protection, improves microclimates, and promotes resilience in urban design. INTERBETON can develop tailor mix designs on a project-by-project basis to meet specific technical requirements.
ENVIRA combines mechanical strength with water permeability, offering dual durability— both structural and environmental. Its composition enables stormwater absorption, reducing hydrological and thermal stress on urban infrastructure. It is ideal for outdoor applications, ensuring stable performance with minimal maintenance, and can be adjusted to the technical needs of each project.
• 28-day compressive strength: up to 15 MPa. Despite being permeable, ENVIRA maintains structural stability, allowing pedestrians and light vehicles to circulate without failures. This mechanical strength, combined with functional water absorption, ensures dual durability.
• Maximum aggregate size: 16 mm
• Dry density: 1,850–2,000 kg/m.
• Slump / flow class: Not defined
• Permeability (K): Determined per project:
Void content 20–25%
Permeability up to 800 L/min/m. (25% voids) up to 500 L/min/m. (20% voids)
• Depending on design requirements, ENVIRA can be supplied via pumping.
ENVIRA is an advanced concrete solution that combines structural durability with notable environmental benefits. As a small-scale material with broad advantages, it improves urban infrastructure sustainability by reducing flood peaks and heat island effects, while also helping to replenish groundwater.
INTERBETON, with steadfast commitment to innovation and sustainability, offers ENVIRA as a versatile and effective tool for projects that require both technical excellence and environmental responsibility.
HUB 26 is the first large-scale bioclimatic business park in Thessaloniki, redefining the workplace through contemporary architecture and sustainable practices. INTERBETON supported the project with specialized materials and technical expertise, ensuring precision, durability, and high environmental performance, contributing to the creation of a new LEED GOLD–certified business hub.
