Any builders care to comment on this type of construction for pool coping? The builder is using stainless mesh on top of treated 2x4s as the base for the travertine pavers. Concrete is going underneath and around the 2x4s but I’m not sure how this is going to hold up over the long haul. Why would you use 2x4s encased in concrete instead of just pouring a concrete base and laying the pavers on top of concrete? Curious to hear your thoughts. Thanks.
