Shotcrete and Bonding Agent
Shotcrete and Bonding Agent
(OP)
I was called in to look at a 5 yr old commercial structure, one story 60'x84' with a basement. Flat site except for west side which slopes up (vehicle traffic surcharge on east and south sides). Wood framed roof and walls, 2-1/2" conc. slab on mtl deck and bar joists at ground level. Basement slab is SOG. Floor-to-floor hgt = 11'-0". Soils report says at rest EFP = 45pcf. The fdn wall is 8" thick reinf w/ #4 at 24" oc, centered (d=4"). Not surprisingly, every wall has a mid-height horizontal crack. The engineer who designed it has had his license revoked for other, even worse designs. My plan is to shotcrete a sister wall on the inside. I need bond btwn existing and new. I am specifying the existing surface to be roughened to proper amplitude but is there a additive that can be used to increase bond? Maybe a latex modifier?
