TECHNICAL INFORMATION

HydroSEC Type III™ Cork Fillerboard is a semi ridged material manufactured to withstand high traffic movements but still flexible to be able to flex as required in the joint.

NO SYNTHETIC CAPPING/JOINT SEALANT

HydroSEC Type III™ Cork Fillerboard does not require any sealant to prevent the ingress of foreign materials as it will expand to seal the joint when installed in accordance with the ASTM D1752 Type III specification. If specified by the Design Engineer, a Tear Off Cap can be supplied which is being removed after the concrete pour is complete as this can vary in depth as required. 

WATERING

As a natural product, HydroSEC Type III™ Cork Fillerboard needs to be watered so as to activate the expansion process and achieve a joint seal and so the filament tape must be removed, taking away any concrete slurry exposing the cork and then watering it on a regular basis in accordance with the ASTM D1752 specification.
