The DelVal chapter held our February dinner presentation meeting on February 20th at the Philadelphia Marriott West in Conshohocken. The topic was Concrete Slabs for Building Technology Applications, presented by Matt Sherman, PE of Smpson, Gumpertz & Heger. Matt presented on the different types of slabs used in waterproofing, repair, and reconstruction applications. He outlined their behaviors and provided requirements for successful concrete slabs related to waterproofing. The emphasis of the presentation was on design and performance of paving slabs used to support traffic and other heavy loads over waterproofing. There was also a raffle for a golfing foursome at Rock Manor Golf Club, which was won by a representative of Kenseal.
