Cover large areas. Without conventional internal structures.
DVF — Flexible Ventilated Dome for mining, industry, infrastructure and major works.
What is a DVF?
DVF — Flexible Ventilated Dome is Pistelli’s solution for covering large areas. A continuous air system stabilizes the membrane and creates a wide clear-span interior for people, vehicles, machinery and materials.
Explore the technologyAir defines the form. Engineering defines the project.
The membrane is laid out, secured to the ground and gradually raised by the air system. High-speed doors or airlocks support operational access.

Engineering begins with the membrane
Damcovering describes flexible composites using high-strength fiberglass or polyester fabric and HTPES, HDPE, LDPE and PVC films. Final composition is project-specific.
The final configuration depends on engineering analysis and each project’s site conditions.
Access designed around operations
High-speed doors and airlocks can accommodate trucks, tractors, machinery and industrial equipment.
DVF at real-world scale
Pistelli and Damcovering records show the technology across mining, infrastructure, storage, maintenance and construction sites.

01What does DVF mean?+
DVF stands for Flexible Ventilated Dome, Pistelli’s name for its large-area coverage solution.
02How does DVF maintain its form?+
A continuous air system and pressure differential stabilize the membrane. Engineering defines the complete project configuration.
03Does a DVF have internal columns?+
The technology provides a large clear-span interior without conventional internal steel framing.
04Can trucks and machinery enter?+
Yes. Damcovering documents high-speed doors or airlocks for tractors, trucks, machinery and equipment.
05What ground types are possible?+
Damcovering lists sandy, clay, asphalt, concrete and wet ground. Site analysis defines the final interface.
06Can I rent a DVF?+
Yes. Sale, rental and operating lease are commercial formats presented by Damcovering.
07What dimensions are possible?+
Engineering defines dimensions after reviewing the application, site and project conditions.
08How much does a DVF cost?+
Investment depends on dimensions, application, access, ground, location and scope. The configurator structures the initial brief.
