Introduction Chloride ion testing in old slabs is a way to find out whether salt exposure is the real problem behind concrete issues. It helps separate chloride-related damage from other moisture or subfloor failures. In plain terms, it’s part of diagnosing why a floor isn’t performing as you’d expect. Many times, moisture problems drive cracking, […]

Introduction RCPT is a test that measures how fast chlorides pass through cured concrete. It’s a practical yardstick for judging how resistant your concrete may be to corrosion of embedded steel. This article breaks down what low permeability really means in plain language for DIY projects. We’ll cover the basic steps you’d see in an

Introduction Surface resistivity testing measures how easily electricity moves across the concrete surface to indicate how resistant the surface is to chloride ingress. As a DIY homeowner, you can view it as a quick check that helps you judge durability without tearing into the slab. Think of it as a simple, hands-on indicator you can

Introduction Half-cell potential testing is a quick field check that estimates the likelihood of corrosion on embedded steel by measuring electrical potential at the surface. It’s a screening tool, not a crystal ball, and results should be used with other observations. Always follow the device instructions and local rules when you perform it. To perform

Introduction Crushed glass as aggregate is using recycled glass pieces as the rock substitute in concrete. There is an alkali-silica reaction risk with crushed glass, which varies with glass type, particle size, and the concrete mix. Always check product labels, supplier instructions, and local rules for ASR guidance and suitability. Mitigation strategies include choosing less
