HVM Flex Planter System – Modular PAS 68 Hostile Vehicle Mitigation Planter

The HVM Flex Planter System is a fully modular, bespoke hostile vehicle mitigation solution engineered to suit complex public‑realm layouts while providing discreet but robust defensive capability. Manufactured in powder‑coated mild steel or corten steel, the system can be configured using straight, inside‑corner, outside‑corner, and curved modules—allowing specifiers to create seamless perimeter protection that doubles as attractive urban landscaping.

Each planter incorporates Townscape HVM CT Blocks installed within the planter walls, ensuring genuine PAS 68 vehicle‑impact performance while maintaining a clean, architectural aesthetic. The Flex system is designed so that virtually any space can be fully filled using either standard sizes or custom‑made components, offering unmatched layout flexibility. All retaining walls are required to be at least 600mm high to completely cover the internal CT blocks, ensuring proper performance without visual compromise.

PAS 68 Testing & Security Performance

The Flex system uses CT Blocks tested and certified to:

• PAS 68:2010 – Single block tests:
• 30 mph: V/7500/N2/48/90/6.6/0.0
• 40 mph: V/7500/N2/64/90/12.3/2.2
• PAS 68:2005 – Staggered block test:
• 30 mph (3 blocks): V/7500/N2/48/60/2.0/0.0

These classifications validate the system’s ability to resist high‑energy hostile vehicle attacks while integrating seamlessly into landscape designs.

Installation & Construction

The Flex Planter System requires a minimal 100mm installation depth, significantly reducing ground disruption—ideal for retrofit environments or sites with underground utilities. Modules are fabricated in 3mm mild steel or corten steel, and are powder‑coated to suit architectural requirements. Bespoke dimensions are available to meet specific project needs.

Typical Module Sizes (Examples)

Common mild‑steel components include:

• Straight walls: 1000 / 1500 / 2000 mm lengths
• Inside corners: 500x500 mm
• Outside corners: 1000x1000 mm
• Curved sections: 1500x1500 mm
  All with a 600 mm height minimum.

This modularity enables smooth curves, tight corners, long linear runs, and complete perimeter enclosures, making the system suitable for plazas, station forecourts, retail developments, business districts, and high‑footfall public spaces.
