6 Best Outrigger Pads For Soft Ground Stabilization

Working on soft or saturated ground while operating heavy lifting equipment is a recipe for a catastrophic site accident. Stability begins with the footprint of the outrigger, as even a small shift in soil density can lead to a boom tipping over. Choosing the right pad is not just about convenience; it is about site safety and equipment longevity. This guide breaks down the best options on the market to ensure your rig stays level and secure during any lift.

DICA Safety Tech D2424: The All-Around Workhorse

The D2424 is widely regarded as the gold standard for contractors who move from site to site regularly. Its engineered thermoplastic construction offers an incredible strength-to-weight ratio that remains unbreakable under extreme pressure.

Unlike wood that splinters or steel that rusts, this material is impervious to harsh weather, chemical spills, and UV degradation. It acts as a reliable buffer, effectively distributing vertical load across a wider surface area to prevent sinkage on damp residential lawns or loose fill.

For general crane or aerial lift operations, this pad hits the sweet spot between durability and manageability. It is the go-to for crews that prioritize a “set it and forget it” mentality on diverse job sites.

AlturnaMATS Premium: For Serious Heavy Lifting

When the soil is truly marginal, such as after a heavy rain on a commercial project, AlturnaMATS provides the high-friction surface necessary to keep the pad from sliding. These mats are built with a proprietary polyethylene that flexes slightly under load rather than cracking.

The flexibility allows the pad to conform marginally to uneven terrain, providing a more consistent contact patch. This is essential when working with heavy-duty boom lifts or concrete pumpers where every square inch of bearing surface counts.

Choose these if the equipment is heavy and the job site conditions are consistently unforgiving. The traction provided by the tread pattern is a significant safety feature for operations on slight inclines.

Bigfoot Custom Pads: Built Tough for Any Rig

Bigfoot pads are frequently specified for heavy-duty applications where standard off-the-shelf sizes do not cut it. These pads are manufactured with high-density materials that provide a rigid, unyielding platform for larger machinery.

They are particularly effective for contractors who operate larger telehandlers or cranes on uneven, rocky, or soft ground. Because they are often produced in customized footprints, they can be matched precisely to the outrigger plate diameter to ensure zero lateral movement.

Expect a longer service life from these than traditional wood cribbing. While they require a dedicated transport plan due to their weight, the peace of mind offered during high-stakes lifts is substantial.

Checkers Diamondback: Top Pick for Portability

Portability is the primary focus of the Diamondback series, featuring a distinct design that prioritizes ease of handling without sacrificing structural integrity. These pads are lightweight enough for a single operator to position, which speeds up setup time on fast-paced residential roofing jobs.

The underside features a molded-in handle, making it a favorite for teams that move their equipment frequently throughout the day. Despite the lighter weight, the material composition is high-strength, non-conductive, and resistant to oil and moisture.

This is the ideal choice for smaller aerial work platforms or light-duty cranes. For the operator who needs to carry, place, and retrieve pads solo, this is the most ergonomic solution available.

Reliable Equipment 18×18: Best Bang for Your Buck

The Reliable Equipment 18×18 pad serves the contractor who needs a dependable, no-frills solution for standard residential or light commercial work. It is priced for teams that need to equip multiple rigs without breaking the equipment budget.

While it lacks the heavy-duty engineering of premium composite pads, it is more than sufficient for everyday stabilizing needs on reasonably firm ground. It prevents the outrigger foot from punching through asphalt driveways or soft sod.

Treat this as the essential entry-level tool for any truck. It is robust enough to handle the daily grind while keeping costs down for smaller outfits or expanding fleets.

Greatbear Stabilizer Pads: A Solid Budget Option

Greatbear offers a balanced compromise for those needing large-surface stabilization at a reduced price point. These pads are highly resistant to impact, meaning they can handle being tossed into the back of a truck or dropped on a job site without shattering.

They are particularly useful for contractors who frequently work in suburban environments where protecting the ground surface—like a homeowner’s pavers or irrigation system—is a primary concern. The pad distributes the load efficiently enough to prevent surface-level damage.

Use these for lighter-duty stabilization tasks where equipment weight is not pushing the extreme limits of the pad’s rating. They provide a cost-effective way to ensure ground protection on almost every job.

Sizing Your Pads: Load Ratings and Ground Pressure

Determining the right size pad is a simple matter of physics. The goal is to reduce the “pounds per square inch” (PSI) exerted by the outrigger to a level that is lower than the soil’s safe bearing capacity.

• Soft Soil/Clay: Requires a large footprint to spread the load significantly.
• Hardpan/Gravel: A smaller, high-strength pad is usually sufficient.
• Asphalt/Concrete: Focus on surface protection; use a pad to prevent the steel foot from cracking the surface.

Always calculate the maximum weight the outrigger will support, including the equipment’s own dead weight plus the load. Never underestimate the ground pressure; a dry-looking lawn can hide a high-moisture water table that will liquefy under pressure.

Wood vs. Composite Pads: Which Material Is Best?

Wood cribbing is the historical default, but it comes with significant drawbacks. Timber is prone to rot, splitting, and unpredictable failure modes when moisture content changes.

Composite pads offer consistency and longevity that wood simply cannot match. While composite pads carry a higher upfront cost, they do not require replacement every season and offer predictable load-bearing performance regardless of humidity or temperature.

The only scenario where wood remains relevant is in emergency “make-do” situations on a site. For professional, repeatable, and safe operations, composite materials are the only choice that offers verifiable safety.

Proper Pad Placement on Unstable or Soft Ground

The surface beneath the pad matters as much as the pad itself. Ensure the ground is as level as possible; if the terrain is sloping, use appropriate leveling cribbing beneath the pad to prevent the outrigger from sliding.

Position the outrigger foot directly in the center of the pad. Off-center loading creates bending moments that can lead to pad failure or equipment instability.

Clear away any debris, rocks, or uneven sticks before setting the pad. A single jagged rock under a composite pad creates a high-pressure point that can cause it to crack over time.

Inspecting and Maintaining Your Outrigger Pads

Treat your outrigger pads with the same care as your power tools. After every use, inspect the surfaces for hairline cracks, deep gouges, or excessive warping that might indicate the internal structure is compromised.

Clean off mud and grease after the job. If the pads are left covered in debris, the material can degrade, or they may become dangerously slippery for the crew walking around the site.

Store pads horizontally to prevent them from developing a permanent bow. If a pad shows signs of deep structural cracking, retire it immediately; no lift is worth the risk of a pad giving way under a fully extended load.

Investing in high-quality outrigger pads is a foundational decision that directly impacts the safety and efficiency of any heavy-lifting project. By selecting the right material and size for your specific equipment and terrain, you mitigate the risk of site accidents and protect your machinery from undue stress. Always prioritize gear that exceeds the maximum anticipated load, and your crew will operate with the confidence required to get the job done right.
