Water-powered operation
The gate’s flood-blocking movement requires no electrical drive, according to WSGL’s product information.

Flood barrier installation in Hong Kong
Prepare your entrance. Before the water arrives.
Cypress works with WSGL on flood barriers and automatic flood gates for Hong Kong car parks, shops, shopping centres and property entrances. One contact coordinates the site survey, product selection, quotation, supply, installation and maintenance.

01 / THE SYSTEM
Hydrodynamic automatic flip-up flood gates
Junli product information is provided by our partner WSGL. We review the entrance and proposed scope with the partner to identify an appropriate solution.
Automatic response
The barrier responds to incoming water. Keep the movement area clear and follow the operating instructions.
Planned maintenance
Arrange checks, cleaning and servicing for the chosen model and site conditions.
- 01
Day-to-day access
The gate rests at the entrance. The selected installation must suit everyday pedestrian and vehicle access.
- 02
Water rises
The partner’s hydrodynamic design uses buoyancy to lift the gate as flood water arrives.
- 03
Barrier raised
The raised panel forms the barrier. Protection height and site interfaces are confirmed during design.
Other options to discuss
WSGL also lists hand-cranked swing gates and smart flood systems. Monitoring and PA options can be discussed; availability, interfaces and power requirements are confirmed for the selected proposal.
02 / YOUR SITE
Start with the entrance you need to protect
- Basement car parks and ramp entrances
- Shopping centres, shopfronts and underground entrances
- Public lift and railway station entrances
- Plant rooms, substations and other entrances requiring flood-risk assessment
These are potential applications, subject to a site assessment. Photos and video on this page are partner references, not Cypress project records.
03 / FROM SURVEY TO SERVICE
One contact for the work ahead
- 01
Tell us about the site
Send the address and entrance photos, with flood history and your target programme.
- 02
Survey the entrance
Survey the opening, floor, drainage and everyday access requirements.
- 03
Confirm the proposal
Agree the model, responsibilities, quotation and access plan with the partner.
- 04
Install, test and maintain
Install and test the agreed scope, hand over operating information and arrange maintenance.
Confirm before work starts
- Confirm the design water level, loading, civil works and drainage against the site and selected model.
- Automatic operation still requires maintenance: keep the movement area clear and inspect seals and drainage.
- The quotation identifies the contracting company, partner responsibilities, scope, maintenance and warranty terms.
Useful details for a quotation
- Site address and entrance photographs
- Opening width and floor or ramp drawings, if available
- Previous flood locations, water levels and drainage conditions
- Vehicle access, working hours and management requirements
Flood barrier cost: what should an installation quote include?
Car parks, shopfronts and existing buildings have different entrance conditions. Compare automatic flood gate quotations against the same scope using these four checks.
- Opening dimensions and model
- Confirm opening width, design water level, everyday vehicle or pedestrian access and gate configuration. Include any specified brand, model or tender requirements.
- Floor, side interfaces and drainage
- Check whether floor alterations, side sealing and drainage works are included. Retrofitting an existing entrance requires a review of site conditions.
- Installation and management access
- Identify entrance closures, phased works, working hours and building-management requirements. Supply and installation timing follow the confirmed proposal.
- Testing, handover and maintenance
- Separate handover tests, operating information, routine servicing, parts and warranty terms. List any monitoring, warning or PA equipment and its interfaces separately.
Common questions
Are flood barriers and flood gates the same product?
Both terms are used for entrance flood protection, but the name alone does not establish how a product operates, its design water level or installation requirements. This page focuses on the hydrodynamic automatic flip-up gate offered through our WSGL partnership. Send any specified model or tender requirements for review.
How do I enquire about a flood barrier?
Email or call with the address, premises type and entrance you need to protect. Photos, dimensions and flood history are useful, but you can get in touch before everything is ready.
Does the automatic gate need electricity?
WSGL describes the Junli hydrodynamic gate as using buoyancy to raise the barrier without an electrical drive. Any additional monitoring, warning or PA equipment needs its own confirmed power and interface requirements.
Can a barrier be retrofitted to an existing entrance?
We can arrange an assessment. Floor conditions, side interfaces, drainage, vehicle loading and access need review before the model and associated work can be confirmed.
How are price, lead time and maintenance agreed?
Pricing depends on dimensions, model, access and associated works. The proposal sets out supply timing, installation, testing and maintenance terms.
