RocBloc™ Debris Containment

RocBloc™ is InCord’s exclusive debris containment netting solution. Built on years of experience and extensive testing, RocBloc is North America’s leading debris containment option. The dual layer net design can contain up to 10,000 pounds of worksite debris from steel beams to fine particles. RocBloc panels are custom designed and fabricated to your exact job requirements for a perfect fit, maximizing safety and reliability.

From bridges to facades and even entire buildings, RocBloc panels wrap around the debris source to prevent materials from becoming hazardous falling or flying objects. Be a step ahead of disaster and ensure a safe worksite for workers, pedestrians and property.

When installed from a walking/working surface, RocBloc provides both debris containment and OSHA compliant fall protection for workers at height. (OSHA 1926.502) Falls are one of the greatest dangers on construction sites and the leading cause of death. Fall protection is important at any height, and with RocBloc, the solution couldn’t be easier.

Custom built in the USA

RocBloc is available in three tested strength ratings for optimal performance for your application. RocBloc installs close to or against the debris source by a system of tensioned wire cables. Instead of stopping debris that is falling from height, RocBloc surrounds the debris source, holding back wood, steel or concrete spalling to prevent a costly falling debris incident. RocBloc is reusable with proper inspection, maintenance and project application analysis and approval.

RocBloc’s versatile performance is made possible by two net layers combined in a stacked configuration. These two layers are combined using a bordering technique that provides maximum strength and easy hook-up grommet attachment points.
