Case Study
Big Creek - Roswell, GA
Situation
Two raised pedestrian walkways along the Big Creek Trail in
Roswell, GA, were experiencing frequent flooding and silt
buildup, creating hazardous conditions for trail users. The city
needed a reliable solution to prevent further erosion and
ensure safety.
Scope of Work
Cantsink was engaged by the general contractor to provide a
solution. After assessing the existing conditions, it was
determined that the original piles could not be extended due to
uncertainty around their capacity. The project involved removing
the existing decking and piles, and installing new piles at the
correct elevations, with timber brackets, new joists, and decking
to prevent future flooding.
Anchor System
Cantsink installed 10"/12" double helix helical piles with galvanized
2.875 o.d. configuration using an Eskridge 5500 drive head. A
pattern of three piles per bent (two outer and one alternating
center battered pile) was followed, with 13 piles in the first section
and 45 in the second. Average pile depths were 21 feet in Section
1 and 34 feet in Section 2.
Result
The height of the walkways was raised by approximately one
foot, eliminating flooding. The new piles were successfully
installed, and decking was placed on the timber brackets. The
City of Roswell was satisfied with the results, and the local
community can now safely enjoy the trail.
