    Overcoming Concrete Paving Objections

    Register Here

    Many design engineers, contractors and project owners appreciate and fully recognize the significant value of concrete parking lots.  However, there are some that still need some convincing.  This presentation covers concrete parking lot features and benefits and gives suggestions for addressing common concrete paving misconceptions.

    The presenter will be Jason Kruger (Concrete Paving Consultant, Wisconsin Ready Mixed Concrete Association).

    This webinar was developed cooperatively by concrete-related associations from Minnesota, North Dakota, South Dakota and Wisconsin.  The goal of the cooperative effort is to bring a greater awareness of cast-in-place concrete to the design and construction communities via quality continuing education programs.
