HOW DO THEY WORK?
KIE-LOCK splices use a mechanical male-female connection with steel plates and attached rebar anchors precast into the ends of the pile segments.
When splicing, rectangular high-strength steel bars are driven into the matching annular
grooves of the plates, forming a shear key joint.
Male/female splice halves are interchangeable. 24", 30" & 36" sq units have 4 bars at 90°.
- If pile lengths are too long for casting, hauling, or driving in one piece.
- Where low head-room or height restrictions requires short segments.
- Enables the use of smaller equipment for cheaper hauling or driving.
- Where it is in the public safety interest to loft and drive shorter segments.

ADVANTAGES OF THE KIE-LOCK SPLICE
- Specifically engineered for concrete prestressed piles
- Available in 18”, 24” and 30” FDOT approved sizes. (Submittals available upon request)
- Available in 24”, 30” and 36” LA DOTD approved sizes. (Submittals available upon request)
- Designed to meet or exceed any pile capacity or load requirement.
- Adaptable to virtually any pile size, shape, and strand pattern.
- Positive locking – cannot come apart during driving.
- Splicing time is minimal – no welding, grouting, or epoxy needed, minimizing field labor.
- Proven and reliable – tested, and extensively used for 40+ years in all types of projects.
- Design calculations satisfying the latest US and Canadian engineering and code standards for prestressed piles are provided for a variety of approved KIE-LOCK splices.
- The KIE-LOCK is adaptable to virtually every pile design. However, since some
designs have much higher strengths than others, even for the same pile size, it is
necessary to match strength requirements. If the splice was standardized for the
highest strength pile it would be too expensive for the standard commercial pile
design of the region. Splice costs reflect strength requirements.
- The KIE-LOCK is made in customer specified quantities to suit project
TO OBTAIN A FIRM QUOTATION, we need to know as many of these factors as possible per the RFQ form:
- Pile design: concrete strength, strand size, number, and location.
- Any particular bending and/or tension requirements on the drawing or in the specs.
- Possible quantities (minimum number, maximum, how many test piles). Will
there be a small quantity of indicator/test piles needed before production piles
- Best approximation of schedule: when test pile splices and production pile
splices would be needed at the casting yard.
