Concrete Drainage Slope Checks: Simple String and Water Tests Before You Blame the Concrete

Introduction Concrete drainage slope checks are simple on-site tests to verify water runs where you expect instead of assuming the concrete is at fault. Use a taught string or a small water test to see low spots and flow direction before planning fixes. These are hands-on checks you can do with basic tools and a […]

Concrete Formwork for Curves: Kerfing Plywood, Flexible Liners, and How to Keep Edges True

Introduction Concrete formwork for curves means shaping temporary molds that guide wet concrete into a smooth, accurate curved edge, using techniques like kerfing plywood or flexible liners to follow the radius you need. In plain terms: kerfing lets stiff sheets bend by cutting relief slots, liners conform with support framing, and both need bracing to

Concrete Spalling at Reentrant Corners: How to Cut Relief Joints That Stop Repeat Damage

Introduction Concrete spalling at reentrant corners is surface and edge breakdown where the inside corner of a slab or wall flakes, chips, or crumbles, and relief joints are cuts you make to interrupt stress paths so the same spot doesn’t fail again. In plain terms: you cut a controlled weak line near the corner to
