There are no “Equivalents”.
TripStop is a unique patented profile that cannot be legally duplicated. TripStop`s profile was designed specifically to stop tree root invasion and soil movement from displacing concrete footpaths and cycleways. Unsurprisingly, as a result of our now dominant market position, some pre-existing jointing systems now claim equivalent functionality.
A Patented Bi-directional Articulating Jointing System
Lock Joint has been used by numerous councils over many years in Western Australia. So there is plenty of in ground evidence to view and analyse across various councils. And it did not take us long to locate evidence of poor performance and even outright failure.
See the images, you be the judge.
If you want your concrete footpaths and cycleways to last 50 years plus, best you don`t specify Lock Joint.
An independent Finite Element Analysis (FEA) comparing TripStop with Lock Joint
An independent FEA that presents the results of computer simulation studies on two PVC profiles used for jointing of pedestrian pavement concrete slabs. The aim of the computer simulation studies was to compare the behavior/movement of the two profiles and the resulting stress distribution in the concrete and PVC components.
The following key points and conclusions can be made from the computer simulation studies:
