Cutting Blocks Safely and Strategically

land the bits all right um scuffing these blocks up very important part of a building wall stan can explain more about that it's just like they get i guess you could call it like overcast on the top where like the channels are and stuff and it's not very much but it's enough to throw your wall off especially say you're doing like an 11 foot wall and your base blocks didn't get scuffed off by the time you get to that point on top of your wall that's that's going to cause some big problems for you stan can explain more about that it's just a very important step i should just say [Music] so it's the story of the princess and the pea basically meaning that a little teeny tiny imperfection at the bottom of the retaining wall can turn into a really big deal when it gets to the top of the retaining wall so you've got to be very careful that at the lowest levels of the courses that all of the block tops match up perfectly and what it's called is slag or overcast during the process of manufacturing what happens is they get just a little teeny tiny little bit of extra concrete and if that isn't removed then that's going to become a major problem down the road but one of the things you got to be super careful of is when you're building an engineered retaining wall is the grid layers because even your grid layers on a tall enough wall can throw it off when you get up high enough but a lot of times what happens is you put a grid down on the top of a block and then you get a little rock trapped between the grid and the block and even that can make your block rock and or could throw off the top so you've got to be hyper critical of everything that happens at the lowest courses once you get up to the top of the courses you can actually be a little bit more forgiving i don't recommend it because then you get into a bad habit i remember i recommend remaining hyper critical throughout the entire process because that becomes just a habit that goes right from the bay the beginning of the retaining wall to the end of the retaining wall but let's play worst case scenario and you miss something and it's close to the top well there's only one course going on on top of the the the spot you missed you might not see it and if it's not structural well then it just becomes an issue of aesthetics but if you're hypercritical throughout the whole process you don't have nothing to worry about anyway so this one right here the face is fine the face is all good we got this big like air…
