TripStop™ Creates Safer Sidewalks – Prevents trip hazards created from misaligned or displaced pedestrian walkways. The ADA considers 1/4" or 6mm to be the maximum allowable variance in walking surfaces.
TripStop™ Saves Costs – Contractors save since it eliminates work involved with cutting control joints during the finishing process. Cities benefit from a 50% to 75% decrease in sidewalk life cycle costs and the elimination of yearly grinding or patching maintenance.
TripStop™ Preserves Mature Trees – TripStop™ moves dynamically with tree roots ensuring sidewalk integrity and protecting trees from the extreme step of root trimming.
TripStop™ Benefits the Environment – TripStop™ is an environmentally green product because it is recyclable and preserves urban trees. The service life of the sidewalk is extended, which means: less waste from construction activity and fewer greenhouse gas emissions from concrete production and service vehicles.
The TripStop™ joint allows sidewalk slabs to move uniformly with tree root growth, soil movement and thermal expansion without creating a trip hazard.

TripStop™ Articulating Sidewalk Joint System Installation - Section 03150
Position the TripStop™ Articulating Sidewalk Joint system at a 90 degree angle to the sidewalk bed with the
galvanized steel installation pins secured in place. Level the soil using the bottom of TripStop™ as a guide so
that there are no voids underneath TripStop™. Pour the concrete into the sidewalk form. Concrete should be
poured on both sides of TripStop™ uniformly without displacing TripStop™ from its proper vertical position.
Ensure that maximum contact is maintained between TripStop™ and the concrete. Use the top surface of
TripStop™ as a screed guide to achieve the desired slab thickness and finish the sidewalk surface according to
accepted finishing procedures.
Independent Laboratory Testing
Testing at an independent laboratory
measured load and freeze/thaw
characteristics of a TripStop™ Sidewalk
Assembly designed to simulate tree
root invasion, soil expansion and
thermal expansion.
The results confirmed that the stepping displacement was 0.18” or 4.49mm
when concrete slabs were elevated 3" or 76 mm under load conditions ten
times the design load for sidewalk construction.The Americans with Disabilities
Act defines a sidewalk trip hazard as a differential in slab surfaces of 1/4" or 6mm.
The test report is available upon request.
