Josh, We run into concrete that is very hard to grind with typical diamonds. I understand shot blasting may be better for concrete with a hard cap. Would you consider brush hammers an alternative to shot blasting in those scenarios? Thanks
@@jacobnorman4800 that’s a good question. It’s been my experience that bush-hammers are still just as limited by concrete strength as grinding or blasting. If the slab is dense and smooth, it will profile slower than if it were soft. The best way I’ve found to approach a dense slab is to plan 50% more time to prep it. This is a rough increase that’s not precise at all. My thinking is a hard slab will likely take half-again as long as one that’s medium to soft. Usually it’s not slower than this.
