Frequently Asked Questions
Is it OK to use dry-mix (Quikrete-style) post concrete?
Yes for fence and light posts. Pour dry, then pour water into the hole. The concrete sets in 20-40 minutes. For load-bearing posts, structural posts, or mailbox installations subject to vehicle impact, use traditional mixed concrete and let it cure 7 days.
Can I use gravel instead of concrete?
For some fence and deck posts, yes. Tamped gravel allows drainage that extends post life. Treated wood posts in well-drained gravel can last as long as concrete-set posts. Building codes vary - check local requirements.
How long until I can mount the fence?
Wait 24 hours minimum for concrete to set before attaching rails or panels. Full strength comes at 7 days for normal mix, 28 days for full design strength. For windy areas, wait 7 days before attaching panels that catch wind load.
