A New Standard: Radon Gas Protection

In modern construction, the line between quality insulation and health care is becoming increasingly invisible. We are pleased to announce that our long-standing partner, Volteco, has taken another step forward by certifying three of its leading technologies for protection against radon gas. We are no longer talking only about waterproofing, but about a complete system that blocks the path of dangerous soil gases into your home.

Volteco's PLASTIVO 180 is now officially certified against radon gas. The major advantage of this waterproofing solution is the CORE CURING TECHNOLOGY.

Why choose Plastivo 180?

CORE CURING TECHNOLOGY: The waterproofing cures from the "inside-out," which guarantees fast and uniform curing even at low temperatures and on damp substrates.

Speed: Allows for a second coat and tile bonding within 48 hours — without the long wait.

Radon Certificate: Stops both dangerous soil gases and water in a single system.

Flexibility: Performs equally well under both positive and negative hydrostatic pressure.

With PLASTIVO 180, you shorten project timelines without compromising on safety.

BI MORTAR PLASTER SEAL is a waterproofing "breathable" mortar that is now officially certified for radon gas protection. It is the ideal solution for transforming old and damp basements into healthy living spaces.

Why choose BI MORTAR PLASTER SEAL?

  • Two-in-one Formula: One of its greatest advantages is that the product simultaneously levels and waterproofs the substrate, significantly simplifying the workflow.

  • Resistance to Negative Pressure: It possesses excellent resistance to negative hydrostatic pressure (up to 50 kPa), making it ideal for interior basement walls where water presses against the structure from the outside.

  • Fiber-reinforced: Exceptional mechanical resistance and strength without the risk of cracking.

  • Easy Restoration: Specifically designed for application on old masonry (brick, stone, concrete) even in the presence of moisture.

  • Sulphate Resistance: Suitable for aggressive environments where ordinary mortars would fail.

With BI MORTAR PLASTER SEAL, renovation now means categorical safety for your health.

Why is BI FLEX important for your project?

  • It seals joints and cracks — the primary points through which gas typically penetrates a building.

  • Elasticity: Absorbs significant structural movements and vibrations without losing its airtight seal.

  • Chemical and Physical Resistance: Resistant to aging, weathering, and aggressive environments.

  • Universal Installation: Easy and secure application on both concrete and masonry structures.
