Opening protection
Door and garage barriers can be efficient where the building envelope is otherwise suitable and flood entry is concentrated at known openings.
Decision Centre / Global
Which type of flood barrier fits the site?
Flood protection starts with the water route, not the barrier product. Doorways, garages, gates, wider openings and perimeter approaches create different structural and operational requirements.

Direct answer
The short version.
Use opening barriers where the flood pathway is concentrated through doors, garages or gates; use wider demountable systems where large openings need repeatable closure; and use temporary perimeter systems where the project needs rapid deployment across changing flood paths.
Project decision
What matters before product selection.
Use these points to structure the first project conversation. Final suitability stays tied to the actual site, selected system and local project team.
Demountable wider barriers
Posts, side channels and stacked panels can protect gates or wider spans, but water pressure, leakage expectations and supporting substrate must be reviewed.
Rapid temporary perimeter
Portable modules can support emergency or temporary deployment where fixed openings are not the only water pathway. Storage, staffing and deployment time become critical.
Comparison matrix
Flood barrier comparison
No barrier should be selected without understanding where water can bypass it.
| Pathway | Best use | Main planning issue |
|---|---|---|
| Door / small opening | Known entry point | Frame / wall interface |
| Garage / gate / wider opening | Repeatable closure | Span, posts, water load |
| Temporary perimeter | Flexible deployment | Storage, people, route length |
| Property-wide strategy | Multiple pathways | Drainage, bypass and continuity |

Frequently asked
Answers without oversimplifying the project.
Is there one best flood-barrier system for every project?
No. Site conditions, scale, permanence, local works, operating expectations and documentation requirements change the right starting point.
Does Apollo calculate project pricing automatically online?
No. Apollo uses a manual project-brief process so the selected system, quantities, destination, freight and project interfaces are checked before pricing.
Who handles local engineering, approvals and installation?
Apollo is primarily a supply-only project-supply specialist. Local engineering, approvals, foundations, services, installation and other site work remain with the appointed local project team unless a written project scope states otherwise.
Next step
Turn the research into a real project brief.
Send the site, dimensions, intended use, quantities and known local requirements. Apollo will review the relevant product pathway and keep local engineering, approvals and site-work responsibilities explicit.
