New Foundation for a Packaging Machine built in Germany

Dom Packaging 4-1-14 press 6 #6 WebThis is a new foundation for a machine built in Germany that has never been built before or installed anywhere in the United States. We had to assist the owner in design and execution of this project. The support of the plates into the new 3′ thick concrete was a challenge the design team know what they wanted but could tell us how to do the install because it never had been done. We designed a steel support system that allowed us to span the opening and adjust the plates so that they would be perfectly level prior to the pour and after the pour.

Specialized Construction Work, Trench Drain

W.J. Rapp provided and installed custom made trench drains for soy sauce factory in Richmond, Virginia. The soy sauce had eaten the existing metal and plastic trench drains. We were able to provide new fiberglass trench drains with continuous slope in 20’ sections allowing fewer seams and less cleaning issues. We also provided fiberglass grating and fiberglass angle which will never have to be replaced again.
