Our products were tested for Florida DOT earlier this year. We recently got the news, that our pile splices have just received Florida DOT certification with very promising results as follows:

​

Two 18 inch x 18 inch x 20 foot pile segments were spliced using an Emeca splice connection. After positioning the segments end-to-end with a crane, the splice connection was completed within minutes. 
The resulting 40-foot long pile was load tested in four-point bending to determine the flexural capacity of the splice connection. The connection exhibited a dutile loaddisplacement response and an experimental moment capacity of 273 kip-ft. The experimental capacity exceeded the target capacity of 245 kip-ft based on requirements from FDOT Specification 455-7.8 Pre-Planned Splices.
