Removing Tile and Blasting a Gym Floor at Collegium Charter School

removing tile and blasting a gym floor at Collegium Charter School in Exton, PAWe had the opportunity to help one of our clients, Collegium Charter School in Exton, PA, with their new gymnasium floor. We removed the tile from the 6,400 sq ft surface and blasted the concrete underneath.

For safety reasons, when installing a floor in a gym, it is crucial that the surface is free of any cracks and that it is smooth. This will significantly reduce the risk of tripping and falling.

Blast and Seal in Fredericksburg, VA

Back in September, we traveled to Fredericksburg, VA to take on a project for a customer. We performed a blast and seal on a 220,000 sq ft surface.

Another great 1500 grit polish at Jersey Mikes

We were called again by our friends at Christopher Kunes Construction to polish another Jersey Mikes Sub Shop. As always Shotblast answered the call and delivered a fantastic looking floor. Starting from metal diamonds we worked all the way up to 1500 grit.

If you’re ever in Mechanicsburg, PA stop by to take a look at the floor and enjoy a sub.

Shot Blasted 495 bridge over Christina River in Wilmington, DE

The bridge over the Christina River in Wilmington is having some work done to it. In order for the contractor to be able to apply new coatings to the bridge it first has to be prepared.

This week we shot blasted 425,000 square feet on the north bound side of 495.



1500 Grit Polish at Jersey Mike’s in York, PA

No job is ever the same. In this business it is very hard to give blind bids because of the uncertainty surrounding each job. Every concrete floor is different and every floor has a different history of treatment. That creates unique challenges when heading into a job.

We also love the customers that we work for, and Christopher Kunes Contracting has been a great customer of ours. He came to us with his latest project, a Jersey Mike’s Sub shop in York, PA. The previous use of this floor left behind a lot of mastic/glue from the tiles that used to cover the floor. When the demolition phase started, they began to remove the tiles and left behind a number of divots in the floor.

Our first job was to prepare the floor by grinding the mastic off. We used 30/40 metal bond diamonds to do that, followed by 60/80 metal bond diamonds. After the floor was ready, we began polishing with our 100 grit transitional diamonds and worked our way up to 1500 grit. In the end the job looked spectacular.




Shot blasted I-476 bridge deck to C.S.P. 5-6 outside of Scranton, PA

Mar-Allen Concrete was renovating the I-476 bridge ramps going down into Clark’s Summit, PA. They were ready to install a high friction overlay and needed the concrete appropriately prepared. Naturally they contacted us about shot blasting the bridge so their overlay would properly adhere and give lasting quality and reliability to the ramp.

Since the job was time sensitive our crew went up the night before and stayed in a hotel in order to start working first thing in the morning with no time lost. Deck had tines and our crew blasted to a Concrete Surface Profile (C.S.P) of 5-6. Using our diesel powered BW machines we were able to shot blast 45,000 sq. ft. in just 8 hours. As always we magnet swept and cleaned up excess shot after the job.
