Cracked concrete beam with a sealed crack and injection ports, connected by a hose to an injection gun. Structural cracks in beams, columns & slabs Cracks in load-bearing members can come from overload, settlement, corrosion or design faults, so an engineer must find the cause first. Dry or damp cracks are then bonded by epoxy injection; leaking cracks follow the leaking-cracks guide. 7 steps Wall section with water-bearing soil outside; angled drilled packers inject resin into the crack from the dry inside face. Leaking cracks & active water seepage Cracks and holes that let water through basement walls, tanks, roof slabs or retaining walls. First stop running water, then seal the crack with elastic injection, then waterproof the surface; rigid epoxy is not used while a crack is wet. 7 steps Plastered wall with hairline cracks filled from a caulking gun and a facade coating being rolled over the repairs. Surface & plaster cracks (non-structural) Hairline and map cracks in plaster, renders and concrete surfaces, mostly from shrinkage and heat, which let rain in and spoil paint. This guide covers telling them apart from structural cracks, filling them with the right sealant, and preventing them in new plaster. 7 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) Adding capacity to beams, columns, slabs and walls with bonded carbon or glass fibre fabrics, for change of use, design or construction defects, corrosion loss or seismic upgrading. This is engineer-designed work installed only by trained specialists. 7 steps
