We have the following materials called out in the 03 30 00 Cast-in place concrete spec:
1. Semi-rigid joint filler
2. Bonding Agent
3. Epoxy bonding adhesive
When/where these are applied inside the weatherproofing membrane of the structure - which category do they fall under for specing the VOC limit? We are struggling with adhesive/sealant products specific to Concrete use.
You rely on LEEDuser. Can we rely on you?

Hello
I don't know if this is directly helpful, but within my guide spec for concrete, it says:
Liquid floor treatments shall have a VOC content of 200 g/L or less
Curing and sealing compounds shall have a VOC content of 200 g/L or less
For joint filler, you might consider using the following:
Sealant Primers for Porous Substrates: 775 g/L
Other Sealants: 420 g/L
Epoxy is much trickier, as it exceed allowable VOC content for LEED projects. I believe you can still use an 'epoxy allowance' if there is no other product option for the application.
