Product Description

Protect your home, business, or property instantly with RAINBOW’s Water-Activated Flood Dam Barriers — a modern, sandless alternative to traditional sandbags. Designed for quick deployment during emergencies, these lightweight yet powerful flood barriers absorb water rapidly to form a strong and stable wall against flooding.

Each flood dam is filled with Super Absorbent Polymer (SAP)-infused paper (1 or 2 layers), which expands upon contact with water. The outer shell, made from durable non-woven fabric or canvas, ensures resilience and reusability. Within minutes, the bag can weigh over 18 kg, effectively blocking and diverting floodwater to protect critical areas.

Perfect for doorways, garages, construction sites, basements, and leaking tanks, RAINBOW flood barriers are easy to store, environmentally safe, and 9× more effective than traditional sandbags.


Key Features

  • 💧 Rapid Water Activation: Expands within minutes on contact with water.

  • 🧱 High-Performance Protection: Strong, stable, and reusable — ideal for emergency flood control.

  • ⚙️ Durable Materials: Outer layer made from non-woven fabric or canvas for lasting use.

  • 🌿 Eco-Friendly: Non-toxic, safe, and decomposable over time.

  • 🧩 Customizable Setup: Stack multiple bags in a brick pattern to increase wall height.

  • 🟡 Color Options: Black, dark green, and yellow available.

⚠️ Designed for use with fresh water only. Not suitable for salt or sea water.


Available Sizes

25×50 cm, 25×70 cm
30×60 cm, 30×70 cm
40×60 cm, 20×150 cm
25×150 cm, 25×300 cm


How to Use

  1. Submerge the barrier fully in fresh, cold water.

  2. Within 3–5 minutes, it will inflate and reach over 18 kg in weight.

  3. Position it to block, divert, or contain floodwater as needed.

  4. For higher barriers, stack multiple bags in a brick formation.
