Midwest Mobile Waterjet recently completed a challenging hydro-demolition project on the Brighton Dam near Baltimore Maryland. The project required hydro demolition of approximate 16,000 square feet of shotcrete, over a concrete base on the spillway of the Brighton Dam. Do to the varied thickness of the shotcrete and the softer compressive strength of the base slab this removal proved to be very challenging. However, no challenge is too great for MMW and we were able to design a system and process that satisfied the specification and was approved by the project engineers. The project also required strict waste water treatment monitoring and disposal which again MMW was able to perform admirably.
