Life Cycle Structure Costs
We looked at life-cycle costs, and the heavy-duty nature of the PermaTrak is
going to long outlast wood or other materials we could have used. It gives
us the look we wanted but with a much more durable material.

Simplified Boardwalk Construction

Steel Forms
Experience
Quality Control

Lifting Equipment
Mini excavator or small Bobcat recommended to
handle precast components

Installation: Abutments
Beginning/ending precast component
Standard widths are 39 nominally

Installation: Shallow Foundations

Installation: Deep Foundations
Cast-in-place concrete caissons
Steel
H piles

Foundations: Cap to Pile Connection Detail
Pinned connection
Sealed with epoxy to prevent entry of corrosive elements

Spherical connecting pins fit precast
slots in bottom of beams
Installation: PermaTrak Beams

Main load bearing element

Installation: PermaTrak Treads
Shown here using Bobcat with slings
Treads spaced with 1/8 gap on bottom
Walking surface provides consistent 3/8 gap
between treads

Installation: PermaTrak Treads

Installation: Curbs
Fastened to tread with epoxy adhesive
Flexibility and speed of construction

Aluminum railing
Installation: Railings

Improved Quality of Life
Durable and consistent performance for park
visitors, cyclists & runners

Boardwalk Challenges and Solutions!

Riverwalks/Promenades

Boardwalks

Coastal

Ponds/Lagoons

Lakes/Fishing Deck

Sand Dunes
Lack of trip hazards
No more splinters
Remains ADA-compliant

Stream Crossings

Pedestrian Bridges

Trails/Greenway Systems

Urban Greenspace

Sensitive Sites
Consistent walking surface for decades
Eliminate warping, twisting, splitting

Viewing Platforms

Wildlife Observation

Elevated Platform

River Floodplain
Wet/dry cycle expedites deterioration of timber or composite products

Wetland/Floodplains
Sandblast texture preferred by owners

Wetland/Floodplains

Prescribed Fires/Arson
Precast concrete does not support combustion
Consideration for prescribed fire areas or
arson problems
