Introduction Under-slab plumbing sleeves are protective conduits that allow pipes to move slightly under a concrete slab to prevent leaks. They give a controlled path for movement so joints don’t crack or rub on sharp edges. This intro will lay out the practical ideas you’ll need to know when planning or checking sleeves on a […]

Introduction Termite shields in concrete slabs are physical barriers and detailing practices that help deter termites from entering the structure. They sit at the interface between soil and slab and are installed during pour to block termite paths. Along with proper moisture control and detailing, they reduce the chance termites take up residence. Termites favor

Introduction Frost heave is when the soil pushes up under a slab as water freezes and expands. You’ll notice uneven edges, cracks, or a section that lifts after cold spells. This is a hands-on issue you can spot by watching how the ground around the foundation sits through freezing and thawing cycles. Moisture in the

Introduction Edge thickening is adding extra concrete at the edge of a slab to strengthen it and slow cracking. It helps when you’re edging against forms or when a transition needs more support. If you’re deciding whether you need it, consider the load, use, and the edge exposure—check the project details and local guidelines. Do

Introduction Sonotube footings are cylindrical form tubes used to shape concrete footings and keep them plumb during pour. They help prevent soil from collapsing around the pour by providing a stable, vertical mold. Before pouring, set the tubes on a solid base, check alignment with a level, and brace as needed. Sizes and installation steps

Introduction A concrete form blowout is a formwork failure during placement: a panel bows, a joint opens, a tie or anchor moves, or the form collapses and releases fresh concrete. Treat visible movement or rapidly increasing leakage as a stop-work condition, not a cosmetic problem. Do not use generic brace dimensions as a design. Formwork

Introduction Drilling rebar dowels is the process of making a hole that the steel bar can sit in securely. Key takeaways Verify embedment depth per plans and code requirements before drilling. Choose drill bits matching hole diameter and concrete hardness per label. Drill slowly with steady pressure to reduce blowouts and surface spalling risk. Clean

Introduction Concrete finishing in direct sun means you need shade, moisture control, and smart timing to get a smooth, durable surface. Shade helps slow rapid moisture loss, fogging or misting adds surface cooling, and timing keeps finishing steps aligned with the concrete’s surface condition. Plan ahead to avoid streaks, itching, or surface damage from heat

Introduction Flood testing a shower pan is a hands-on check where you fill or pressurize the pan with water to look for leaks before finishing the shower surround. This introduction gives you a practical sense of what to watch for and why the test matters. It’s a simple step you can do on a DIY
