Stackable Protection

Modular panels for flexible height adjustment

What is a Stoplog Flood Barrier?

A stoplog flood barrier (also called flood stop logs, stop log barriers, or stackable flood barriers) is a modular flood protection system for openings. Permanent side posts/guide channels are anchored to the structure. During a flood warning, panels are stacked into the channels to create a barrier up to the target water level. After the risk passes, panels are removed and stored.

Best for

  • Sites that need protection only during storms
  • Multiple entrances that require quick deployment
  • Locations that want unobstructed access in daily operation

How the Stoplog System Works

Five key components working together for reliable flood protection

1

Side Channels / Guide Posts

Fixed to the structure to resist water pressure and keep panels aligned.

2

Interlocking Stoplog Panels

Panels stack vertically; interlocking edges help stability and sealing.

3

Compression / Locking Mechanism

Top clamp or locking device secures the stack and compresses seals.

4

Sealing System

Replaceable side and bottom gaskets reduce leakage and improve reliability.

5

Optional Base Plate / Threshold

Improves bottom sealing, protects gaskets, and helps with uneven floors.

Complete Protection

Key Advantages of Stoplog Barriers

Why stoplogs are the preferred choice for flexible flood protection

Fast Deployment

Panels install only when needed--suitable for repeated flood warnings.

Flexible Protection Height

Increase or reduce height by adding/removing panels.

Easy Storage

Panels store compactly, ideal for sites with limited space.

Reusable and Maintainable

Gaskets are replaceable; panels are designed for repeated use.

Scalable Across Multiple Entrances

Standardize on one system and deploy where needed.

One side inside, one side outside for constraints

Stoplog system adaptation for uneven floors and out-of-square frames

Deployment Steps (Simple SOP)

1

Clean contact area (floor and channels)

2

Insert panels and stack to height

3

Engage locking/clamping mechanism

4

Quick seal check (visual + feel)

5

After event, remove panels and store dry

Material Options

Aluminum vs Stainless Steel: Choose the right material for your application

Aluminum Stoplog Flood Barriers Popular Choice

Aluminum Stoplog Flood Barriers

Lightweight--faster for manual deployment
Good corrosion resistance for most urban/coastal environments
Ideal for frequent deployment and multi-opening sites
View Aluminum Flood Barriers →
Stainless Steel Stoplog Flood Barriers Premium

Stainless Steel Stoplog Flood Barriers

Higher robustness for harsh environments
Preferred for certain industrial conditions or compliance needs
Maximum durability for critical applications
View Stainless Steel Flood Barriers →

Quick Guidance

If deployment speed and handling are the priority, aluminum is often preferred. If the environment is highly corrosive/industrial or demands higher robustness, stainless steel can be selected.

Our team can help you choose the optimal material based on your specific requirements.

Frequently Asked Questions

Everything you need to know about stoplog flood barriers

Are stoplog flood barriers watertight?

Stoplogs are designed to minimize leakage using compression and gaskets. Performance depends on installation quality and surface conditions.

How do I choose the protection height?

Use your target water level / risk requirement. We can recommend panel count based on your site and photos.

Can stoplogs be used for a garage door?

Yes. Garage/carpark entrances are one of the most common use cases for stoplog flood barriers.

What if my floor is uneven?

We can address uneven floors with base plates, leveling, and sealing strategies. Share a floor close-up photo for the best recommendation.

How fast can it be deployed?

Deployment time depends on opening width and height. Stoplogs are designed for quick manual installation with basic training.

Aluminum or stainless steel--what's better?

Aluminum is lighter and often chosen for frequent manual deployment. Stainless steel is used for harsher environments or higher robustness needs.

Is the system reusable?

Yes. Panels are removable and reusable; gaskets are replaceable maintenance parts.

Do you provide drawings and installation guidance?

Yes. We provide drawings and installation guidance based on your opening dimensions and photos.

What is the typical lead time?

Lead time varies by project size and customization. Contact us with your requirements for an accurate timeline.

Can you ship to my country?

We export to multiple countries across Southeast Asia, North America, and Europe. Contact us to confirm delivery options for your location.

Do you offer installation services?
