• Timely securing: the support system against the aluminum corner profiles allows the barrier to be positioned in just 5 minutes, enabling rapid isolation of the premises at the first weather alarm.
• Superior hydraulic protection: the use of closed-cell foam gaskets prevents the absorption of liquids and perfectly seals the contact points, physically and tightly blocking infiltration.
• Coverage for large openings: the adjustable extension from 252 to 504 cm allows protecting wide commercial windows, double industrial doors, or large driveway entrances with a single and practical device.
• Uninterrupted accessibility of premises: the completely removable nature of the bulkhead leaves the entrance free from trip hazards and fixed obstacles during normal traffic conditions and daily work.
• Autonomous structural preparation: the complete supply of sealing adhesive, plastic plugs, and lag screws allows performing the pre-installation of the profiles while immediately having all the necessary technical hardware available.

This large modular bulkhead is intended for installation on wide openings, such as double doors, extensive shop windows, and entrance gates of private homes, street-facing shops, warehouses, and large commercial premises heavily exposed to hydrogeological risk. It represents fundamental physical security equipment for property owners, logistics managers, and administrators who need to isolate exceptional openings up to over 5 meters wide. It is the ideal infrastructural solution for urban or productive contexts where the overload of sewer networks or the rise of the road level rapidly directs large masses of water towards the entrances.

The h729_65 model constitutes the correct technical choice when the operational prerequisite demands coverage of exceptionally wide openings (up to 504 cm) while maintaining extreme speed of assembly during the emergency phase. Unlike the invasive construction of containment walls or the massive, precarious, and exhausting use of sandbags, this barrier is indispensable because it offers a solid 15 mm plywood surface that is totally removable and reusable. It is the optimal logistical option for blocking pressing water, being able to rely entirely on a system of high-performance closed-cell gaskets, ensuring constant mechanical seal against the pre-installed corner profiles.

How does this plywood bulkhead differ from using sandbag barriers?

Unlike traditional sandbags, which require very long times for correct positioning, high physical effort, and never guarantee a linear hydraulic seal against the wall jambs, this barrier offers solid and continuous shielding. Once the pre-installation of the corner profiles is performed, the panel is assembled in just 5 minutes, sealing the opening cleanly and mechanically counteracting the push of the water without the aid of heavy materials, which are hygroscopically unreliable and complex to store.

Do the insulating materials used meet the performance parameters to resist water pressure?

Yes, the locking and sealing system exclusively uses gaskets made of closed-cell foam, a specific and indispensable technical requirement for high-performance waterproofing. Unlike common sponges, the closed-cell structure physically repels liquids without absorbing them. This ensures that the two vertical gaskets in contact with the aluminum profiles and the horizontal one on the floor guarantee constant insulating pressure, effectively blocking water volumes up to 60 cm high.

What needs to be prepared on site to perform the three hours of frame pre-installation?

The product is supplied in a kit with the essential hardware for assembly, including plastic plugs and lag screws for fixing, plus a cartridge of sealing adhesive to anchor the two aluminum corner profiles with a perfect watertight seal. The user or installer will only need to have basic tools (such as a drill to perforate the masonry or flooring) and a classic silicone extruder gun (not included in the package) to correctly apply the supplied sealant.
