Construction Waterproofing Film mc expert FOLIA BUDOWLANA HYDROIZOLACYJNA ECO 5x20 m 0.3 mm

mc expert FOLIA BUDOWLANA HYDROIZOLACYJNA ECO 5x20 m 0.3 mm is a construction waterproofing film designed for general-purpose moisture protection. Supplied as a roll 5 m wide and 20 m long with a 0.3 mm thickness, the film provides a continuous vapor and water barrier for foundations, basements, retaining walls and underfloor layers. It is intended for use where a simple, economical waterproofing membrane is required to protect structures from groundwater, splashing and capillary moisture.

Advantages

The film offers uniform thickness and continuous coverage across large areas, enabling quick installation and overlap sealing. Its 0.3 mm gauge balances flexibility with puncture resistance for typical building-site conditions. Being lightweight and supplied in a convenient roll makes transport and handling easier compared with rigid membranes. The product is compatible with common civil-engineering and building-detailing approaches where a vapor and water barrier is needed.

Suitable for

• Horizontal and vertical damp-proofing of foundation slabs
• Basement wall and floor moisture protection
• Retaining wall waterproofing where drainage is present
• Temporary or permanent underfloor vapor barrier

Key specifications

• Roll dimensions: 5 m width × 20 m length
• Material thickness: 0.3 mm
• Form: flexible film in roll form for overlap joints
• Primary function: continuous vapor and water barrier
• Intended use: civil and building envelope moisture protection

How to use

Unroll the film onto a clean, level substrate free of sharp protrusions or debris. Allow for sufficient overlap at joints (typically 10–15 cm or according to local practice) and ensure laps are sealed by heat welding, adhesive tape or compatible sealing methods suitable for thin polyethylene film. When used vertically, provide temporary support until backfill or finishing protects the membrane. Verify compatibility with insulation, drainage layers and any applied coatings prior to final installation.

Usage recommendations

Store the roll flat or standing in a dry location away from direct sunlight and heat sources. Avoid stretching the film during placement and protect from mechanical damage until covered. For long-term installations, combine the film with appropriate drainage and protective layers to reduce the risk of puncture or displacement.
