concrete repair in wastewater treatment tanks
i am doing concrete repair in a wastewater treatment tank containing run-off containing oil and gas and some human waste.  i am having a hard time finding repair mortar for overhead and vertical repairs that will withstand exterior exposure, freeze thaw and sulfate attack. does anyone know of good repair mortar for exterior concrete wastewater treatment tanks?  anyone have any advice or pitfalls to watch out for when designing repair of concrete wastewater treatment tanks?
check out our whitepaper library.
i would give sauereisen a call. they have all type concrete repair products.
call your local basf rep.
check into five star structural concrete v/o.  i've gotton good reports from the field on the five star products that i've specified for repair.
i would contact sika corporation (
i agree with jheidt2543, but the website address is wrong:
thanks jed, my chubby fingers missed a few keys!
i have checked with sika.  they don't offer any products that can withstand the wastewater environment.  i thought there might have been another product or company that specializes in the wastewater repair industry or at least produce products for more extreme environments.
fosroc
flexcrete
irathane futare
do a search on internet for these companies, all deal with wastewater, used all at some stage.  
the five star repair product i mentioned above lists "resistance to sulfates" as one of it's advantages.  also, low chloride ion permeability.  i've specified it for wastewater treatment repairs with good results.  v/o stands for vertical and horizontal repair applications.
here is the right page.
