Concrete

Concrete is where I keep my step-by-step guides for planning, pouring, and finishing concrete projects.

Topics include base prep, forms, reinforcement, thickness, mixing and placing, finishing, curing, sealing, and long-term durability. I also cover troubleshooting—what to do when concrete cracks, scales, dusts, or cures unevenly.

If you’re new to concrete, start with the planning and prep articles. They prevent most of the expensive mistakes.

Concrete Fibers Explained: Microfiber vs macrofiber and what each actually does

Introduction Concrete fibers are tiny reinforcing additives added to concrete to improve crack resistance and durability. Microfibers are very fine fibers that help control tiny cracks and plastic shrinkage, while macrofibers are larger and designed to increase toughness and impact resistance. In DIY terms, you’ll notice better handling and fewer tiny cracks, but you still
