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.

Anti-Static Floor Coatings: When They Matter in Workshops and DIY Limits

Introduction Anti-static floor coatings are coatings that reduce static electricity buildup on concrete floors. In a workshop or DIY space, they help prevent shocks and protect sensitive tools. Choose a coating that suits foot traffic and cleaning needs, and follow the label for surface prep. Before applying, test the concrete for moisture and cleanliness, and […]

Epoxy Anchor Failure Modes: Dirty Holes, Wet Holes, and Wrong Cure Temperature

Introduction Epoxy anchor failure happens when the hole is dirty, wet, or the cure temperature is off. In real job sites, debris, moisture, or the wrong curing conditions keep the epoxy from bonding to the concrete. That shows up as low pullout, hairline cracks, or anchors that spin. Always clean the hole, dry it, and

Anchoring into Old Concrete: When the Surface Lies and How to Test Strength

Introduction Old concrete can be unreliable for anchors because the surface may lie about overall strength. The outer layer can look solid even when cores are weak. That means you need a simple test to verify what you’re drilling into. Start by listening for a hollow sound and looking for flaking, spalling, or cracks near

Concrete Placement in Congested Rebar Without Honeycombing: Sequencing, Head Pressure, and Vibration Control

Introduction Concrete placement in congested rebar without honeycombing means planning and executing pours so concrete flows around dense steel without leaving voids. Take time to prep formwork and rebar layout, then sequence pours to keep flow paths open and minimize segregation. Choose direct discharge or pumping as your method, and use appropriate vibration and tamping

How to Brace Tall Forms for Hydrostatic Pressure: A Practical DIY Design Check

Introduction Bracing tall forms against hydrostatic pressure means preventing movement and failure by anchoring and tying the forms securely. This introduction walks you through practical checks you can do on site, without heavy jargon or guesswork. Keep the focus on stability, simplicity, and safety as you set up supports. Before you pour, check that your

Form Liner Basics: Getting Consistent Texture and Avoiding Trapped Air Patterns

Introduction Form liner basics mean using flexible surface liners in concrete forms to shape texture and finish. They define the pattern you pull from the concrete and help control air pockets as the mix cures. We’ll cover how to choose liners, how they sit in the frame, and what to look for during setup. To

Plastic Rebar Chairs vs Wire Chairs: Avoiding Rust Staining and Punch-Through

Introduction Plastic rebar chairs are non-metal, lightweight supports that keep rebar off the form and away from the wet concrete. Unlike wire chairs, they won’t rust and stain the concrete, which helps with a cleaner pour. Check that the chairs are rated for the cover you need and compatible with your rebar size before using.
