Introduction An isolation joint is a gap that lets the concrete slab move independently from walls and columns to prevent cracking. In this article we cover where to put them around walls and columns in a DIY-friendly way, not a textbook. Check local rules and manufacturer instructions for placement guidance. Geotechnical soil conditions and reports […]

Introduction Ferrocement is a thin, reinforced cement mortar system that uses mesh and a cementitious mix to build lightweight, curved shells like planters. It relies on multiple coats and a strong mesh lattice to hold shape and resist cracking. It’s a hands-on technique that you can adapt for small DIY projects, with attention to formwork

Introduction Concrete creep is the slow, ongoing deformation that happens in hardened concrete under sustained load. It means the material slowly changes shape over time as it bears weight from countertops and shelves. In plain terms, the longer something sits on concrete, the more it can sag or shift a little bit. Common causes include

Introduction Sorptivity is a measure of how quickly a porous material absorbs water through capillary action. In this DIY intro, we’ll keep the test simple and describe what you can observe on a small patch of concrete or plaster. The goal is to get a practical sense of absorption behavior without high-tech gear. Results help

Introduction Radon fan placement is choosing where to install the fan so it can move soil gas from beneath the slab to the outdoors. Pick a location that is accessible for maintenance and close enough to the intake so air can be drawn through the system. Always follow the manufacturer’s instructions and local rules when

Introduction Radon rough-in under a slab is routing and sealing a pipe under a concrete floor to vent soil gas safely. Do this with plain instructions: plan the path, verify access, and seal joints to limit leaks, while following local rules and manufacturer notes. Before you start, check local rules and follow any recommended testing

Introduction A capillary break under slabs is a layer or treatment that stops water from wicking from the soil into the concrete. In plain terms, it keeps moisture away from the slab to prevent dampness and cracking. Choose a method and materials that fit your climate and slab design. Foam-glass options can be used as

Introduction Cellular concrete is a lightweight concrete mix used for trench backfill and under-slab fill. It is also known as foamed or aerated concrete, and it’s discussed as a DIY-friendly option with attention to local rules and product instructions. It’s not a substitute for every job, so check what your project requires first and follow

Introduction Foamed concrete for insulation is lightweight concrete that includes air voids or foam to slow heat transfer. This article gives a practical, hands-on overview for DIY homeowners. It helps you know what to check on labels or with the manufacturer before you mix or apply it. Common failures include moisture intrusion, cracking, and poor

Introduction Foamed concrete is a lightweight mix used for making planters and fill, mixed with air-entraining foam to reduce weight. This article walks you through practical, hands-on steps for mixing, placing in forms, and finishing for a durable, good-looking result. Check the product instructions and local rules for material limits before you start. Choose the
