Concrete beam with a square cut-out repair: cleaned steel bars coated, and repair mortar being trowelled in flush. Spalling concrete (chhajja, balcony, beam, column) 7 steps Concrete section with steel bars: one zone rebuilt with repair mortar, the rest treated with inhibitor and a rolled-on coat. Rusting reinforcement (rebar corrosion) 7 steps Concrete building facade half coated with a protective coating by a roller on a pole, with rain beading off. Protective coatings & water repellents for concrete 8 steps Concrete beam between two columns with a carbon-fibre strip bonded to its underside and fabric wraps near the supports. Structural strengthening (FRP wrapping) 7 steps Tunnel arch in rock partly lined with sprayed concrete, with a rig nozzle fed by an accelerator line spraying the rest Shotcrete, tunnels & slope stabilisation 7 steps Thick raft placed in layers by a pump hose, with a temperature sensor and a chart showing a lower, flatter heat curve Mass concrete & set retarding 6 steps

Concrete beam with spalled cover exposing rusted steel bars, cracks along the bar line, honeycombing and broken pieces below. Damaged or spalling concrete Broken edges, honeycombing, exposed steel 12 products Slump test: a stiff mix holds the cone shape; after adding an admixture the mix flows out flat, measured against a rule. Better concrete mix (admixtures) Workability, strength, pumping, ready-mix 29 products Wall with a window: diagonal cracks run from the window corners, plus a vertical crack and a crack monitor fixed across one. Cracks in concrete Cracks in slabs, beams or walls 2 products Joint between two panels moving apart: the sealant has torn away from one side and rain gets in through the gap. Leaking or open joints Expansion joints, gaps around windows and façades 5 products Basement below the water table: water pressure grows with depth and pushes in through a wall crack and the wall-floor joint. Ground water coming in Basements and foundations below the water table 4 products Damaged pocket in a concrete slab being filled with repair mortar, with a stopwatch for fast setting and a snowflake for cold. Fast-setting concrete & repairs Quick turnaround, cold weather 4 products Section through a wall with damp soil behind it: water seeps in and rises in the wall, leaving a tide mark and flaking paint. Water leakage & seepage Damp walls, seelan, leaking basements, tanks or bathrooms 14 products Concrete beam bending under heavy load, with vertical cracks underneath at mid-span and diagonal cracks near the supports. Strengthening concrete Higher loads, structural strengthening (engineer advice needed) 11 products Roof slab section: rainwater ponds on a torn waterproofing layer, runs through a crack and drips from the ceiling below. Roof leakage Chhat leakage, wet ceilings after rain 6 products Concrete floor worn by forklift wheels: the surface skin is gone along the tracks, exposing stones and raising dust. Dusty or worn floors Factory and warehouse floors that dust or wear 5 products Threaded anchor rod set in resin in a drilled hole, holding a steel plate under an upward pull, breakout cone dashed. Anchoring & fixing Rebar, bolts and base plates into concrete 4 products Floor tiles on adhesive dabs: two tiles have lifted into a tent over a hollow gap, found by tapping for a hollow sound. Tiles coming loose Hollow-sounding or cracked tiles, failed tile bond 4 products Vibrating machine on a base plate held up only by shims and bolts, with an empty gap above the concrete foundation. Grouting gaps under plates & machines Base plates, machine foundations 3 products
