Garrison Flood Control - Oversized Large Sand Filled Flood Bag Barriers - 5-Compartment Bag

Garrison Flood Control – Oversized Large Sand Filled Flood Bag Barriers (5-Compartment Bag)

The Beluga™ Bag Barrier is a unique, concertina-style flood control system ideal for protecting important property and infrastructure. This heavy-duty, oversized bag is divided into 5 separate chambers that can be filled with sand, aggregate, or other fill materials to create a strong levee to hold back floodwaters.

Each Beluga bag ships flattened on pallets and is ready to be positioned and filled onsite. Measuring 15 ft long, 3 ft deep, and 40 inches high, a single 5-compartment bag replaces approximately 750 standard sandbags. Because it eliminates wasted space, Beluga barriers require about half the sand compared to equivalent sandbag barriers, significantly reducing labor and material needs.

Beluga bag barriers can be rapidly deployed and filled by a small crew, making them perfect for timely flood response.

Protect Against Heavy Flooding

Beluga big bag flood barriers provide quick, effective protection against major flooding for municipal buildings, homes, neighborhoods, infrastructure, and more. Ideal applications include:

Water Diversion: Divert water away from sensitive infrastructure to protect property from rising floodwaters.

Sewer Drain Sealing: Place oversized bags on sewer drains/outlets to prevent sewage backflow from flooding.

Cofferdams: Contain water in a specific area, blocking flow and preventing migration.

Levee Heightening: Reinforce or raise existing levees; fill gaps or repair breaches.

Coastal Erosion: Protect waterfronts and erosion-prone areas efficiently, with minimal site prep.

Storm Surge Protection: The heavy fill and 40” height help Beluga bags withstand heavy storm surges, stopping floodwaters effectively.

Speed of Deployment

Designed for quick and easy deployment by unskilled labor.

Each 5-chamber bag weighs approximately 50 lbs when empty.

With proper equipment and a two-person crew, a 100 ft berm can be installed in about 2.5 hours.

Bag Capacity

Each section holds 30 cubic feet of sand; total 150 cubic feet per 5-compartment bag.

Safe Working Load: 4,500 lbs per chamber; 22,500 lbs total per bag.

Damming Ability

A single layer of Beluga Bags withstands up to 3 ft of water.

Multiple bags can be stacked up to 9 ft high (requires engineer sign-off).

Ground-conforming design contours to surfaces including concrete, asphalt, sand, grass, and mud.
