Careers in the Aggregates, Concrete & Cement Industries
The Pennsylvania Aggregates and Concrete Association (PACA) is the industry’s unified voice, representing more than 200 member companies across the state.
Creating a unified and strong voice for our industry.
PACA monitors and analyzes local, state and federal regulations and advocates for a balanced approach by the regulators.
PACA members and staff work to address technical issues with these common goals: proper use of materials, based upon sound materials engineering practice; protection of member companies and the materials they produce; sustainable use of valuable natural materials – aggregate availability; and, the professional and personal growth of PACA members through their involvement and engagement.
One of the most effective tools in government relations for an industry is a robust advocacy/grassroots strategy.
In the last legislative session, we contributed over $275,000 to our political champions.
