SHOREGUARD AND C-LOC INSTALLATION
Because no two seawalls are the same, and numerous job site variables make it impossible to provide specific construction methods for every job, a careful analysis of each variable and the effect it will have on the structure should be determined by a professional marine contractor or engineer. The following is a step-by-step installation procedure taken from years of contractor field experience with ShoreGuard and C-LOC.

MATERIAL HANDLING

ShoreGuard and C-LOC are relatively lightweight, but still require appropriate material handling equipment to unload and stage the materials on site.

PAIRING SHEET PILING

When using “Z” shaped sheet piling, position two bundles end to end to increase pairing speed. When using “box” shaped sheet piling, pairing is not required.

 
BUILD A DRIVING GUIDE

A proper driving guide saves time and improves wall alignment. Using a string line will not offer support during driving and may allow the sheet piling to wander out of plumb. Some contractors recommend placing a second, temporary wale to improve sheet piling alignment and installation speed.

 

DRIVING SHEET PILING

It is preferable to install sheet piling with the male lock positioned in the direction of driving. When the female lock is leading, the interlock cavity may fill with compacted soil, making the sheet piling more difficult to drive.
     
         
         

For proper wall alignment, use a level to ensure that the sheet piling is plumb and driven to finished grade. Use lag screws to attach the leading sheet piling to the driving guide or wale. By lagging each pair of sheet piling to the driving guide or wale, you prevent them from moving out of alignment or being overdriven into the soil. In most cases, it is recommended to drive each pair of sheets to grade before driving the next pair.
TURNING CORNERS
Corners are used to make 90º and 45º bends. For walls with gradual curves, the tolerance in the locks allow for radius turns with approximately 10º per pair of sheet piling.

 

 


ANCHORING TIED BACK WALLS

Vertical piling anchors are commonly used in anchoring systems. And in some instances, horizontal drag piles are added to vertical piling anchors for increased anchor resistance. Many also utilize individual concrete anchors or continuous concrete anchor walls.

 


BACKFILLING

Your choice of backfill influences the amount of force acting on the seawall. Use granular, free-draining backfill such as sand, gravel or shell. Backfill in “lifts” or layers, compacting each as you go. Weep holes may be installed to provide additional drainage.

 

 

CAPPING THE WALL

A wide variety of capping options are utilized with ShoreGuard and C-Loc sheet piling. Our ArmorWare™ Cap gives a sleek appearance and is simple to install.

Properly constructed concrete caps or pressure treated wood caps are also and option, but may require greater maintenance.
