Sitemap

This page explains how the site is put together and where to start looking. It is written for people; search engines use the machine-readable XML sitemap instead.

The site has one organizing idea: one question, one page, answered in the first paragraph. Everything below is a different way into that.

Questions

Questions is the main body of the site. Each page takes a single question someone actually typed — “how much concrete do I need,” “why is my slab cracking,” “when can I drive on it” — and answers it directly, then goes deeper with named sources at the bottom.

Questions are grouped into topic clusters rather than listed alphabetically, because concrete questions arrive in clumps. Someone asking about cure time is usually about to ask about sealing. The clusters cover the whole arc of a job:

• Getting started — basics and definitions, what concrete is made of, concrete versus cement
• Planning and numbers — estimating and quantities, cost and pricing, mix design and PSI
• Building it — pouring and placement, slabs and foundations, footings and frost, rebar and reinforcement, joints and cracking, finishing and troweling
• The specific job — driveways, patios and walkways, garage floors, fence posts, countertops and castings
• Conditions — hot and cold weather, ready-mix delivery, tools and equipment
• After the pour — curing and drying time, sealing and waterproofing, cleaning and maintenance, repair and resurfacing
• Looks — staining and coloring, stamped and decorative, polishing and grinding, painting and coatings, flooring over concrete
• Rules and risk — codes, permits and inspection, safety and silica, contractors and hiring, commercial and structural, sustainability and low carbon, demolition and removal

Each cluster has a hub page listing every question in it, so you can browse a topic end to end instead of hunting one question at a time. Individual question pages live under their cluster, and we do not list them here — there are far too many, and the cluster hubs and site search are better tools for finding one.

Calculators

Calculators covers the arithmetic of a job: slab, footing and column volume, bag counts, truckloads, rebar, control joint spacing, cost, cure timeline, sealer coverage, gravel base, and PSI to MPa conversion.

Every calculator shows its formula and its assumptions, works entirely from the keyboard, and keeps your inputs on your device. They are estimating aids, not engineering. Confirm quantities with your supplier before you order.

Concrete prices by state

Concrete prices has a page for each of the 50 states and the District of Columbia, plus a hub explaining the whole picture.

These pages are deliberately different from what you will find elsewhere. Published US ready-mix prices disagree by nearly two to one, so instead of inventing a single authoritative number we name each source, give the range it reports, and chart the federal producer price index as the objective trend. Our methodology documents exactly how we do that and why.

Colors

Colors covers decorative concrete color: the coloring methods (integral color, dry-shake hardener, acid stain, water-based stain, dye, tinted sealer, release color), the manufacturer color systems, and individual color pages grouped into families. Color names belong to their manufacturers and are used here as editorial reference.

Standards

Standards summarizes the ASTM, ACI, OSHA and federal documents that actually govern concrete work in the US — what each one covers, who needs it, and what it does not cover — with a link to the official source.

We summarize scope and purpose in our own words. We do not reproduce the text, tables or numeric limits inside a paywalled standard, and no summary here is a substitute for the document itself.

Glossary

The glossary defines the vocabulary you meet on a delivery ticket, a spec sheet or a jobsite: what the term means, how it is used in practice, and which related terms it gets confused with.

Brands

Brands covers the manufacturers you actually encounter — bagged mixes, cement and ready-mix, admixtures, sealers, color systems, tools and fibers. These pages are editorial reference. We are not a dealer or representative for any of them.

Spanish

Every page on this site exists in Spanish at /es/, with localized addresses rather than English slugs behind a language folder. The Spanish site is a localization written for US Spanish-speaking readers, not a machine translation — it uses concreto, keeps imperial units first with metric in parentheses, and reads the way a jobsite actually sounds.

The language switcher in the header takes you to the matching page in the other language, not to the homepage.

Finding one specific thing

Site search is faster than this page. Open it from the header on any page, or press the keyboard shortcut shown there, and type a few words of your question. It searches every answer, calculator, standard, glossary term and state page on the site.
