Underlayment film for concrete foundation – protection and stability of lightning protection systems

The A-400 underlayment film for concrete foundation, catalog number 94308021, is a key element ensuring the durability and safety of lightning protection systems. The ELKO-BIS brand product is designed for use under the foundations of masts, spires, and down conductors, creating an insulating layer between the concrete and the ground. This simple yet extremely important solution protects the structure from moisture and potential mechanical damage.

Application and benefits for professionals and end users

This film is not just a mounting element – it is an investment in long-term protection. For installers, it means easier installation and confidence in the stability of the structure. For the end user, it guarantees the reliability of the lightning protection system and protection against the effects of atmospheric discharges. The film prevents moisture from penetrating the concrete, which minimizes the risk of it cracking due to temperature changes. This ensures that the foundations remain stable for years to come, and the entire installation operates efficiently.

• Moisture insulation: Protects concrete from dampness, preventing corrosion and weakening of the structure.
• Increased durability: Extends the service life of mast and spire foundations by minimizing the impact of external factors.
• Easy installation: Simplifies and speeds up the installation process of lightning protection elements.
• Versatility: Suitable for various types of lightning protection installations, both new and modernized.
• High-quality material: Provides resistance to mechanical damage and weather conditions.

Product characteristics

The A-400 underlayment film is characterized by its light weight (0.001 kg) and compact dimensions: 0.02 m (thickness) x 0.4 m x 0.4 m. Its main task is to create a barrier between the concrete and the ground, preventing the concrete structure from absorbing moisture. This product is particularly important in areas with high soil moisture or exposed to frequent rainfall. Made of durable material, it ensures the stability of the entire lightning protection structure for years of use.
