Flood DefendTM

A Reliable and Affordable Flood Defence System

High-Performance NF-35G Glass Wall Flood Barrier for Urban Flood Defence

The Glass Wall Flood Barrier from NEWFLAG is engineered for permanent urban flood defence applications where rapid deployment of removable systems may not be practical. Unlike traditional barriers that require manual installation before a flood event, this glass flood wall remains in place year-round, providing continuous readiness against rising water levels.

Key Features of Glass Wall Flood Barrier

  • Transparent Flood Wall: Clear glass panels provide full visibility and minimal visual impact.
  • Permanent Installation: No deployment required during flood events—always in place.
  • High Structural Strength: Engineered for coastal and riverine flood loads.
  • Modular Panel System: Easily scaled to any length with secure splicing.
  • Corrosion-Resistant Components: Suitable for marine environments.
  • Low Maintenance Design: Designed for long-term performance with minimal upkeep.
  • Custom Height and Length: OEM customization for project-specific requirements.

Glass Wall Flood Barrier – Permanent Flood Protection with Aesthetic Integrity

This Glass Wall Flood Barrier can provide the similar protection as our Demountable Flood Barrier, the only difference is that the transparent glass gives the zero visual intrusion to landscape and eye-view, and the full glass wall is permanently constructed with no further installation and deployment any more.
This Glass Flood Barrier with permanent structures is strongly recommended if quick deployment becomes a challenge for any reason on flood event. And it is also a minimal visual intrusion flood prevention solution for those protection areas such as the walkways along the river or lake, amazing beaches and elegant parks, requesting to retain the beautiful landscape.

Modular Glass Flood Barrier System

The extraordinary glass floodwall can be either mounted on top of a half-height foundation structure if required, or installed entirely freestanding on the ground to serve as a pedestrian barrier.

  • The maximum single span for this Flood Glazing can reach 3 meters, while the glass height can reach 1.2 meters.
  • Together with a pre-constructed concrete foundation (if any), the Glazing Flood Barrier provides a complete effective flood protection height of up to 2 meters.

Extendable for Higher Flood Threats
By applying the same design on the end posts and central posts as used in our Removable Flood Barrier NF-35 series stop-log system, this glass wall offers further extension capability against rising floodwaters. Additional aluminum barrier panels can be slid in and seated directly on top of the glass to increase the overall height of the flood barrier when needed.

Structural Design and Materials of Glass Wall Flood Barriers

Utilizing laminated tempered structural glass, aluminum supporting posts designed for static and dynamic loads, robust anchor plates, and watertight seals, this glass wall flood defence system can withstand most flood conditions.

The selected materials and engineered structure keep the barrier stable under pressure, while the seals prevent leakage during prolonged flooding. This makes it suitable for demanding environments where safety and durability are essential.

NEWFLAG Demountable Flood Barrier Advantages

Applications of Glass Wall Flood Barriers

Glass flood walls are ideal where flood protection must blend with aesthetics. It is commonly used in coastal promenades, riverwalks, and public parks to preserve views. Luxury resorts, beachfront hotels, and residential developments also benefit from the transparent design.

Urban waterfronts and commercial districts can protect critical infrastructure like substations and utility corridors. It is also suitable for marinas and ports where visibility and access are required. For large projects, NEWFLAG offers bulk supply and OEM customization.

Factors Affecting Glass Wall Flood Barrier Pricing

The price of a Glass Wall Flood Barrier depends on several project-specific factors rather than a fixed rate. Key elements that influence the cost include:

  • Barrier height and flood level: Higher protection levels require taller glass panels and stronger posts.
  • Glass specification: Thicker laminated tempered glass increases strength and cost.
  • Total length and spans: Longer barriers need more materials and engineering work.
  • Installation and foundation: Freestanding vs. foundation-mounted systems affect labor and groundwork.
  • Site conditions: Coastal or high-wave locations may require corrosion-resistant components and reinforced structures.
  • Watertight performance: Higher sealing standards and longer flood duration demand better seals.
  • Customization: Special sizes, finishes, or architectural integration will change the price.
  • Order quantity: Large projects benefit from bulk pricing and OEM supply.

Flexible Installation Options

This glass wall flood barrier offers flexible installation to suit different site conditions and design requirements.

Option 1: It can be installed on a pre-built half-height concrete foundation, such as an existing low wall. This setup is ideal when you already have a supporting structure in place and want to integrate the barrier seamlessly.

Option 2: It can also be installed directly on the ground as a standalone structure, functioning as a standard pedestrian barrier. This option is particularly suitable for open areas where a quick and clean installation is preferred.

How to Choose the Right Glass Wall Flood Barrier

  • Flood level and protection height: Confirm the maximum flood level and choose a barrier height that meets or exceeds it.
  • Glass strength and thickness: For high wave impact or heavy water pressure, select thicker laminated tempered glass and stronger supporting posts.
  • Installation type: Decide whether the barrier will be freestanding or fixed on a foundation, based on ground conditions and structural requirements.
  • Corrosion resistance: For coastal or marine environments, ensure the posts and fixings are corrosion-resistant.
  • Watertight performance: Check the sealing system and ensure it can prevent seepage during prolonged flooding.
  • Aesthetic requirements: Choose a design that matches the landscape, especially for waterfront walkways, parks, and resorts.
  • Customization needs: If the project requires special dimensions or integration with existing structures, OEM customization should be considered.
  • Budget and timeline: Consider total project cost including materials, installation, and maintenance, and choose a supplier who can deliver on time.
