When it comes to mixing concrete, our industry has come a long way. It wasn’t too long ago that manufacturing companies used the 1-2-4 method: 1 scoop of cement plus 2 scoops of sand and 4 scoops of stone was “good enough.” Just like making brownies or a great sand castle. After all, this is how the Panama Canal was built, so it must be fine, right? No longer. In the world of precast concrete, and specifically at Permacast Precast Concrete Fencing & Walls, we’ve made many advancements in the multiple factors that combine to create durable, lasting concrete. While we absolutely believe in trial and error, we are fascinated by what can be accomplished using technology today. In fact, we stake our reputation on it.
