Craigs Clout and Repairs : Tip "O" the Week ; As many benefits H2O brings to our lives , standing water on some select materials wreak havoc & cost You dollars that you'd rather be investing in other ways I'm most certain . A rudimentry fence post that we have on any given property, if perfomed rightly will last more like 20 years verse's 10. So for All you DIY'ers out there, here is the wisest and most frugal approach. That's a creosote coating (image below) brushed on the SUB-SUFACE of the timber prior to buring, atop a bed of rocks. While finishing the aggregate (concrete mix), its recommended to leave a slope away from the post so water (rain/sprinklers) is never forced to evaporate or rest next to the timber. You'll be glad you did once achieving your old age. Have a Great rest of your Week Everyone! Consult to Save.... Craig 310 697-2829 or craigscloutandrepairs@gmail.com
