A 4x4 fence post in a standard 10-inch hole, 2 feet deep, needs about 1 cubic foot of concrete — roughly 2 bags of 80 lb mix. This guide gives a full volume and bag-count matrix across every common hole diameter and depth, so you can find your exact combination without running the formula yourself.
Fence post depth follows two rules, and the correct depth is whichever asks for more: a third of the post's height, or 6 inches below the local frost line. This guide breaks down frost depth by region, explains why gate posts need extra depth, and walks through worked examples showing how the same fence can need double the hole depth depending on climate alone.
Every fence post concrete calculation follows the same nine steps in the same order, whether it's a small line post or a wide gate post. This guide walks through each step with one running example from start to finish, plus a fill-in-the-blanks worksheet so you can run the same math on your own numbers.
A standard 4×4 fence post needs about 2 bags of 80 lb concrete in a properly sized 10-inch hole — gate and corner posts need closer to 6. This guide covers hole sizing and depth rules by post and fence height, dry-pour vs. wet-mix methods, and how to total up bags for a whole fence line.
US "concrete mix" and UK "cement" aren't the same product — the US bag is a complete pre-blended mix, while the UK bag is usually pure cement powder sold separately from aggregate. This guide compares major brands on both sides, explains the PSI vs. N/mm² strength scales, and covers what to actually buy depending on where you're building.
Most bad concrete orders show warning signs before the pour even starts. This guide covers the red flags for ordering too little (no waste allowance, a suspiciously low bag count) and too much (leftover bags, concrete still in the drum), plus a five-minute sanity check to catch either mistake before you commit to an order.

A concrete slab breaks down into seven manageable steps: plan, prep the site, build forms, add reinforcement, mix and pour, finish, and cure. This beginner's guide walks through each one, including control joint timing, a day-by-day curing schedule, and the mistakes that most often turn a first DIY slab into a cracked one.
A concrete bag carries more useful information than most people ever read — net weight, yield, PSI rating, water amount, and an ASTM code confirming what's actually inside. This guide breaks down every number, explains the difference between concrete mix, mortar mix, and sand mix, and walks through three real label examples so you're buying the right bag before you ever do the math.
