The structural methodology determines the components required for each application. Component selection is influenced by loading, build-up depth, waterproofing interfaces, finished surface and project-specific requirements.
The following systems are supplied and supported by Merx Pacific across residential, commercial and public realm projects.
Silca System is an interlocking structural Support Grate used within elevated paving systems supporting non structural or high load external finished surfaces. The grate distributes imposed loads across the supporting structure while maintaining a permeable construction that allows water to drain freely and promote airflow and drying of the structural assembly.
Manufactured in New Zealand, Silca System integrates with timber joists, aluminium joists, adjustable pedestals and hybrid structural assemblies.
| Applications | Above membrane, above ground and hybrid structural assemblies. |
| Finished Surfaces | Natural stone, porcelain tile, concrete pavers, artificial turf. |
| Material | UV-stabilised PCABS. 100% Recycled material. |
| Key Characteristics | Interlocking Support Grate • Engineered structural component • Compatible with timber, aluminium and pedestal-supported assemblies • Manufactured in New Zealand |

Buzon Adjustable Pedestals provide precision height adjustment for elevated paving systems constructed above waterproof membrane. The modular pedestal range supports both direct paving on Silca Grate assemblies and aluminium joist systems while maintaining access beneath the finished surface for drainage, waterproofing inspection and services.
Buzon pedestals are used extensively across commercial, residential and public realm projects where accuracy, durability and long-term adjustability are required.
| Applications | Roof terraces • Podiums • Balconies • Commercial landscapes • Public spaces |
| Compatibility | Silca Grate • Porcelain • Aluminium joists • Timber joists |
| Material | Copolymer Polypropylene (CPP) 80% Recycled first grade. |
| Key Characteristics | Adjustable height • Integrated slope correction options • High compressive capacity • Modular accessory range • Reusable components |

ShadowDeck aluminium joist systems provide the structural framework for elevated paving assemblies where rigidity, durability and span performance influence the preferred structural methodology.
EconoSpan and SuperSpan integrate with Buzon adjustable pedestal and Silca System Support Grates to create stable structural assemblies for high use residential and commercial applications.
| Applications | Above membrane and above ground structural assemblies. |
| Compatibility | Adjustable Pedestals • Support Grates • Timber Decking |
| Material | Extruded structural aluminium and stainless steel bracketry |
| Key Characteristics | Lightweight • Corrosion resistant • Multiple profile options • Compatible with pedestal-supported assemblies • Engineered for external applications |

JakMat Geocell provides cellular confinement for stabilising granular pavement structures beneath permeable external surfaces. The system improves load distribution by reducing lateral movement within the base course, assisting in the construction of durable permeable paving assemblies.
The confinement system is suited to applications where drainage, excavation depth and ground conditions influence pavement design.
| Applications | Pathways • Accessways • Driveways • Landscape paving • Service areas |
| Finished Surfaces | Gravel • Decorative aggregate • Grass • Permeable paving |
| Material | 100% recycled, UV-stabilised, High-density polyethylene (HDPE). |
| Key Characteristics | Cellular confinement • Load distribution • Reduces lateral movement • Supports permeable construction • Flexible installation • Prevents settlement or cell exposure |
