FloodBloc Wall – ABS Flood Barrier System

Overview

The FloodBloc Wall is a modular flood defence system engineered to stop rising water quickly, safely, and without requiring permanent construction. Each self-anchoring panel locks together to create a watertight wall that redirects or contains floodwater around homes, shops, and public infrastructure.

Developed under Danish-engineered design principles and manufactured to ISO 9001 quality standards, FloodBloc Wall delivers professional-grade protection in a lightweight, easy-to-deploy form.

Material: High-impact ABS (Acrylonitrile Butadiene Styrene) polymer the same durable plastic used in heavy-duty construction components.
Structure: Hollow, rib-reinforced body designed to resist flexing under hydrostatic pressure.
Connection System:

  • Precision-moulded tongue-and-groove joints form a tight, watertight seal.

  • Integrated locking clips secure adjoining panels firmly.

  • Optional corner and end units allow 90° turns or closed-loop installations.
    Stability:

  • Self-anchoring design uses floodwater weight against the curved base for grip.

  • No bolts, stakes, or external frames required.
    Colour: High-visibility red for safety and quick deployment.
    Testing: Independently verified for tensile, flexural, and impact strength (ISO 527-1, 178, 179-1) and UV aging (ISO 4892-3).

• Height per panel: ≈ 0.5–0.6 m
• Length per panel: ≈ 1.0 m
• Setup speed: 10 m of barrier in minutes by one person
• Slope tolerance: ±3 degrees between panels (accommodates mild ground contours)
• Hydrostatic resistance: Withstands floodwater up to ≈ 0.5 m depth with minimal seepage
• Operating temperature: –20 °C to 60 °C
• UV rating: Level 4 (ISO 4892-3) — suitable for long-term outdoor exposure

Recommended Surfaces:
FloodBloc Wall™ performs best on firm, relatively smooth, and stable ground that allows full base contact:

  • Concrete (driveways, footpaths, carparks)

  • Asphalt or bitumen

  • Pavers or tiled areas with tight joints

  • Compacted gravel or hard earth (firm and levelled)

Acceptable with Minor Preparation:

  • Short grass or turf (flatten high points and remove debris)

  • Compacted soil (no loose patches or ruts)

  • Uneven paving (add rubber mat or PVC liner for better sealing)

On soft or uneven terrain, a thin rubber mat, sand layer, or PVC sheeting beneath the base improves the seal and stability.

Not Recommended:

  • Loose gravel, sand, or mud

  • Soft grass or boggy ground

  • Sharp or broken concrete that could damage the base

For challenging terrain, prepare a levelled strip or use a flexible underlay. FloodBloc Wall panels are designed to follow gentle contours of up to ±3° per joint.
