Ground Protection Mat

Ground protection mats are temporary load-bearing panels placed over turf, pavement, or soft terrain to distribute equipment weight and prevent surface damage during construction and events. Available in composite, timber, and steel-reinforced configurations, these mats create stable access roads, crane pads, and work platforms. The industry commonly refers to them as track mats, crane mats, access mats, or by brand names such as AlturnaMAT and Dura-Base.

Fonctionnement

Ground protection mats distribute concentrated point loads across a wider surface area, reducing ground pressure and preventing rutting, compaction, or surface failure. Composite mats typically feature high-density polyethylene or similar materials with tread patterns for traction, while timber and steel mats use laminated hardwood beams or steel-reinforced cores to handle heavier loads. Mats interlock via tongue-and-groove edges, pin connections, or overlap configurations to form continuous roadways or staging areas. The bearing surface transfers equipment weight through the mat structure into the ground below, while anti-slip surfaces maintain traction for vehicles and machinery. Load capacity depends on mat thickness, material composition, and ground-bearing conditions beneath the installation.

Types et variantes

Composite Mats: Lightweight polyethylene or recycled plastic mats, typically 3x8 ft or 4x8 ft, handling lighter equipment and protecting turf, common in events and utility work
Timber Mats: Laminated hardwood beam construction, commonly 8x14 ft to 8x20 ft, providing high load capacity for crane outrigger pads and heavy equipment access
Steel-Reinforced Mats: Composite or timber mats with embedded steel channels or plates, offering enhanced strength for tracked equipment and concentrated loads
Interlocking Track Mats: Modular panels with tongue-and-groove or pin-connection systems, designed for quick assembly into temporary roadways and large work platforms
Outrigger Pads: Compact, high-capacity mats specifically sized for crane and lift outriggers, distributing point loads over soil or pavement

Comment l'industrie le dimensionne

The industry sizes ground protection mats primarily by length in feet. Composite mats up to 10 ft (typically 3x8 ft and 4x8 ft) protect turf and sidewalks under lifts and light vehicles. Mats from 10 to 16 ft, commonly 8x14 ft, form temporary roads and crane pads for tracked machines and trucks. Mats 16 ft and longer, including 8x20 ft timber and steel configurations, serve as outrigger pads and haul roads under the heaviest construction equipment. Load capacity ratings and material type further differentiate sizing within each dimensional category.

Applications

Temporary access roads across soft terrain, wetlands, and turf for construction vehicles and equipment
Crane outrigger pads distributing point loads from mobile cranes, aerial lifts, and boom trucks
Staging areas and work platforms for heavy machinery operations on sensitive surfaces
Event and utility work ground protection preventing damage to lawns, golf courses, and parks
Pipeline and transmission line construction providing stable pathways in remote locations
Emergency access routes for disaster response and recovery operations over compromised ground

Sécurité et opération

Verify ground-bearing capacity and mat load rating match equipment weight and ground conditions to prevent mat failure or soil collapse
Inspect mats for cracks, splintering, or delamination before each deployment, removing damaged units from service
Use proper lifting equipment and rigging when handling heavy timber and steel mats to prevent crush injuries
Ensure mat connections are fully engaged and secured to prevent separation or trip hazards during operations
Transition edges with beveled ramps or tapered mats to reduce trip hazards and vehicle impacts during access

Questions fréquentes

What is the difference between composite and timber ground protection mats?

Composite mats are lightweight polyethylene or recycled plastic panels typically handling lighter loads and easier to handle, while timber mats use laminated hardwood beams for higher load capacities and heavy crane support, though they weigh significantly more and require lifting equipment.

How is mat load capacity determined for different ground conditions?

Mat load capacity depends on both the mat's structural rating and the ground-bearing capacity beneath it. Manufacturers provide mat ratings under standard conditions, but actual capacity decreases on soft soil, requiring larger mat areas or multiple layers to distribute load and prevent ground failure.

What size mat is appropriate for crane outrigger support?

Outrigger mat sizing depends on crane weight, boom configuration, and ground conditions. Composite 4x8 ft mats suit smaller lifts on firm ground, while 8x14 ft to 8x20 ft timber or steel mats are standard for large mobile cranes, with engineering calculations determining specific requirements for critical lifts.

How are ground protection mats connected to form continuous roadways?

Mats connect via tongue-and-groove edges, pin-and-loop systems, or overlapping configurations depending on design. Interlocking systems prevent lateral movement and create continuous surfaces, while proper alignment and secure connections maintain load distribution and prevent separation during equipment travel.
