Building Retrofitting & Structural Repair
Seismic strengthening, carbon-fibre wraps, crack stitching and jacketing — a sustainable, and usually far cheaper, alternative to demolishing and rebuilding an ageing structure.
Buildings Age. Standards Rise. Demolition Is Rarely the Answer.
As buildings age they become more susceptible to structural weakness, and many older structures in NCR were never designed to today’s safety standards — seismic codes included. Retrofitting closes that gap while the building stays standing, occupied and earning.
This is engineering-led work: assessing what the structure can carry, designing the intervention, and executing it with high-performance construction chemicals — concrete admixtures, epoxy resins and grouts, polymer-modified mortars, protective coatings and waterproofing compounds. It is exactly where a distributor-applicator led by a concrete technologist earns its keep: we know the materials because we stock them, and we know the sites because we have worked them since 1987.
What We Retrofit.
Seismic Retrofitting
Foundation and frame strengthening so older structures can meet the seismic demands they were never designed for.
Discuss your buildingCarbon-Fibre Strengthening
CFRP wraps and laminates that add flexural and shear capacity to columns, beams and slabs — without adding dead load.
CFRP systemsCrack Stitching & Repairs
Crack stitching, anchor socks, underpinning and epoxy injection to arrest and re-bond structural cracking.
Injection groutingJacketing & Section Repair
Rebuilding corroded or under-strength members with polymer-modified mortars and repair concretes from MC-Bauchemie and Fosroc.
Repair chemistryEnvelope Upgrades
Insulation, window and facade improvements plus waterproofing and leakage control — the building’s skin brought up to date.
Envelope worksExpansion Joint Cover Retro-Fit
Surface-mounted Dseal covers installed on existing floors and walls — no blockout cutting, minimal disruption.
Joint treatmentFixings matter as much as mortars — covers, plates and strengthening elements go in on proper anchor bolts and fasteners, selected for embedment depth and load, not whatever the hardware shop had.
Four Steps From Doubt to Documented Strength.
| Step | What happens |
|---|---|
| 1 · Inspection & assessment | Thorough survey of the structure — distress mapping, cause identification, what can be saved and what must be rebuilt |
| 2 · Planning & design | Detailed intervention design: which members, which system (CFRP, jacketing, stitching), which materials, in what sequence |
| 3 · Application & execution | Expert crews execute with genuine material from our own stock, staged so the building can remain in use |
| 4 · QA & post-project support | Quality checks at each stage, documentation at handover, and support after the job — not just an invoice |
Retrofitting FAQs.
What are the signs a building needs retrofitting?
Widening structural cracks, exposed or corroding reinforcement, spalling concrete, visible deflection, persistent leakage into structural members — or simply an older building being put to heavier use than it was designed for. An inspection settles whether it is cosmetic or structural.
How long does a retrofitting project take?
A typical project runs 8 to 12 weeks, depending on the number of members treated and access. Work is staged member by member, so the timeline rarely means the building is out of action.
Do occupants have to vacate during the work?
Usually not. Most strengthening work — CFRP wrapping, crack injection, jacketing — is executed zone by zone with localised barricading. Full vacation is the exception, not the rule, and we flag it at the assessment stage if needed.
Is retrofitting really cheaper than rebuilding?
Where the structural frame is sound, yes — significantly. Retrofitting avoids demolition, debris disposal, years of reconstruction and the loss of use of the building. It is also the more sustainable choice. Where the frame is beyond saving, our assessment will say so plainly.
What materials are used in retrofitting?
Carbon-fibre (CFRP) systems, epoxy resins and injection grouts, polymer-modified repair mortars, concrete admixtures, anchor fasteners and protective coatings — all from brands we distribute, including MC-Bauchemie and Fosroc, so specification and supply come from one counter.
