Türkiye's Retrofit Market After the Code Change
A stricter seismic code, a legal route for declaring buildings risky, and a construction sector with spare capacity: how the Turkish retrofit market actually works.

Repair or Replace? The Numbers Owners Actually Ask For
Strengthening is rarely chosen on engineering merit alone. Five comparisons that decide the argument, from downtime and embodied carbon to residual life.
Latest from the desk
Long-form notes on specification, sequencing and the failures that repeat across projects.
Carbonation Depth Testing: What the Phenolphthalein Line Actually Tells You
The purple line is not a measurement of damage. It is a pH indicator read against a rough surface, and misreading it is how good concrete gets replaced.
Seismic Retrofit Sequencing for 1990s Reinforced Concrete Frames
Jackets, wraps and new shear walls solve different problems. Getting the order wrong can load a strengthened column with the demand you just removed from its neighbour.
Writing a Method Statement That Survives the Inspector
A method statement is not a description of what you plan to do. It is the document an inspector uses to decide whether you were allowed to do it. Write accordingly.
Epoxy or Polyurethane? Choosing an Injection Resin for Crack Repair
Both resins go into a crack through a port. Only one of them is structural, and the choice depends on whether the crack is moving, wet or wider than you assumed.
Carbon Fibre Strengthening: Nine Details That Decide Whether the Laminates Work
The design calculation is rarely what fails on a CFRP strengthening job. These are the nine execution details that separate a working retrofit from a decorative one.
Editorial standard
No sponsored placements. No paid links. No exceptions.
Every product reference in this magazine is either generic by type or documented on a real project. We do not sell links, we do not accept guest posts with embedded URLs, and we do not publish supplier-supplied copy under an editorial byline. If a manufacturer wants to argue a technical point, they can do it on the record.
Materials & Methods
Specification, mix design and the chemistry behind durability.
Glass, Carbon or Aramid: A Selection Matrix for FRP Strengthening
Three fibres, three cost points, three failure profiles. A practical comparison of modulus, elongation, durability and cost for structural strengthening.
Carbonation Depth Testing: What the Phenolphthalein Line Actually Tells You
The purple line is not a measurement of damage. It is a pH indicator read against a rough surface, and misreading it is how good concrete gets replaced.

Both resins go into a crack through a port. Only one of them is structural, and the choice depends on whether the crack is moving, wet or wider than you assumed.
Retrofit & Repair
Assessment, strengthening and the economics of keeping what already stands.
Base Plates and Anchor Bolts: Where Strengthening Projects Actually Fail
A column can be perfectly jacketed and still fail at the four bolts holding it down. Anchor installation, hole cleaning and edge distance decide the outcome.
Seismic Retrofit Sequencing for 1990s Reinforced Concrete Frames
Jackets, wraps and new shear walls solve different problems. Getting the order wrong can load a strengthened column with the demand you just removed from its neighbour.

The design calculation is rarely what fails on a CFRP strengthening job. These are the nine execution details that separate a working retrofit from a decorative one.
Site & Project
Sequencing, method statements and the paperwork that protects the work.
Moisture Diagnostics Before You Ever Quote a Waterproofing Job
Most failed membranes were installed over a substrate that was already wet. Six measurements, taken before the quote, decide whether the system has a chance.
Writing a Method Statement That Survives the Inspector
A method statement is not a description of what you plan to do. It is the document an inspector uses to decide whether you were allowed to do it. Write accordingly.
