I’m building a roof over my deck, it will be supported by 2 6×6 posts which will be anchored to a 12″ diam 48″ deep pier. The 6x6s will be anchored with a Simpson post base which is secured to the pier with a 5/8″ expanding bolt.
I poured the piers yesterday, plain old generic concrete bags from the local hardware store. How long should I wait before drilling for the expanding bolts? I’m in southwestern Ontario. It’s pretty warm here, the posts get about 50% sun throughout the day.
thanks – mark
