Installation Simplified

Top-Down Construction

Support H5 Loads

Up to 10,000 lbs (H5 rating), allowing equipment like excavators to work directly from the treads.

low Environmental Impact

Reduces ground disturbance. Ideal for wetlands, forests, and protected habitats.

Streamlined Installation

Fewer crew members and less labor needed, cutting down total labor hours and speeding up timelines.

No Access Roads Required

Eliminates the need for temporary roads or platforms, reducing cost and site disruption.

Improved Safety

Work is done from a stable platform, minimizing risk from uneven or hazardous ground conditions.

Improved Quality

Top-down placement ensures precise alignment and a durable, long-lasting structure.

Top-Down Construction in Action

Built to handle heavy loads. Designed to protect the surrounding environment. 

Frequently Asked Questions.

A compact crew and standard excavator (within weight limits) are usually all that’s needed. Most work is done from the boardwalk itself, reducing complexity.

Yes, that’s one of the key benefits. Top-down construction can handle unstable or waterlogged ground without needing to reinforce the subgrade.

In most cases, no. Because the structure is self-supporting as it’s built, there’s little to no need for ground-level access roads or platforms.

Installation typically begins by anchoring the first section to a stable, grounded area, often using a precast concrete abutment. This creates a solid starting point for equipment to access and begin building the boardwalk outward using the top-down method.

This top-down building system was far superior than trying to float a crane on a barge. Instead, the additional strength of the precast allowed us to place a small excavator to drill the helical piles, switch the excavator attachments, and then place the precast components. I would recommend this system to any others interested in crossing an area with saturated soils, rough conditions, etc
