The PermaLOCK® Difference
A Unique Locking System
PermaLock cylinders are designed to lock together, ensuring every cylinder is torqued and becomes one continuous concrete piling.

With the threading and locking of each PermaLock cylinder there is no lateral movement during or after installation due to expansive soils, soil consolidation, sloping sites, ground pressure or roots of trees. It's strength of design ensures a repair guaranteed to last.

The Result is the "Difference". Straightness, true vertical alignment and concentric loading means PermaLock resists bucking.
