High-performance carbon fiber & glass fiber composite strengthening for concrete structures. No heavy equipment. No production shutdown. No compromise on structural integrity.
Structural problems rarely stop at a single point. A small crack today can become a catastrophic structural failure tomorrow.
Spalling, honeycombing, and flexural or shear cracks in beams and columns — left unaddressed — accelerate the degradation of the concrete core and reduce load-carrying capacity.
The original load capacity of your building is no longer relevant after adding new production lines or heavy machinery. The existing foundation was never engineered for that demand.
Salt exposure and aggressive industrial chemicals oxidize embedded steel reinforcement from within — expanding concrete from the inside before any visible surface damage appears.
Columns that do not meet current ductility detailing requirements in the latest seismic code (SNI/ACI) are at risk of sudden brittle failure during lateral earthquake loading.
Steel jacketing and partial demolition require heavy crane equipment, massive scaffolding, and months of halted production — a double financial loss that most facilities cannot afford.
Concrete jacketing significantly increases column diameter — narrowing corridors, compromising architectural aesthetics, and adding dead load back onto the original foundation.
Estimated production loss per month from facility downtime
Conventional steel jacketing can force a facility to shut down for 2 to 4 months. Add crane mobilization, specialist welding crews, and temporary structural support — and the real cost far exceeds the material bill alone.
FRP Wrapping (Composite) is installed in parallel with ongoing operations inside the building — no cranes, no disruptive grinding noise that shuts down a production floor, and no sprawling work zones that consume your operational space.
Every day of delay is a day when cracks widen further, corroded reinforcement loses more effective cross-section, and the risk of collapse becomes increasingly concrete. An initial assessment takes no time — and it can start today.
Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber Reinforced Polymer (GFRP) are not new to structural engineering — but their correct application, backed by accurate load design calculations and precision surface preparation, is what separates a lasting repair from a temporary fix.
Imagine applying a thin layer of fiber — weighing just 1/5th of structural steel — that, once combined with a structural epoxy resin, transforms into a confining shell with tensile strength up to 10× higher than medium-grade steel. Nothing changes visually from the outside, but the structure's load capacity increases significantly.
Cathpro Indonesia executes this to ACI 440 standards, with a certified team trained to read your building's as-built drawings — not just apply material and leave.
Every advantage listed below is a verifiable technical parameter — not a marketing claim. Ask our engineers for the data sheets.
CFRP tensile strength reaches 3,500–4,900 MPa — far exceeding standard rebar (400–500 MPa). Simultaneously resists axial, flexural, and shear loading demands.
Clean, lightweight installation with no heavy equipment. Building activities, production floors, or port operations continue normally throughout the entire strengthening process.
FRP laminate thickness is only a few millimeters. Negligible dead load addition to the original foundation, zero encroachment on floor space, and no impact on architectural finishes.
Inherently non-corrosive. No reaction to seawater, chlorides, or aggressive industrial chemicals — ideal for port infrastructure, offshore platforms, and petrochemical facilities.
Fiber sheet conforms to circular, square, T-beam, cylindrical silo, and irregular geometries with equal precision. One technology, unlimited applications.
With correct surface preparation and appropriate protective top coat, an FRP Wrapping (Composite) system can deliver 25–50 years of reliable service life with minimal maintenance.
Cathpro Indonesia is a specialist structural strengthening and asset protection company. Our focus is singular: ensuring every project we execute meets international quality standards that can be technically defended and independently verified.
Our field team is certified, trained to read as-built drawings, and strictly adheres to occupational health & safety (HSE) standards at every project site — from multi-storey commercial buildings to port infrastructure and industrial facilities.
Every load design calculation is based on the actual condition of the structure, not assumptions. Because an error at the design stage cannot be corrected after the resin has cured.
Here is one of the projects we delivered — with specific conditions and quantifiable outcomes.
Our client, an automotive component manufacturer, added two new press machine lines with a combined static load of 8 tonnes per point. The existing production floor beams — constructed in 1998 — were not designed for that demand. The conventional option: stop production, erect full scaffolding, cast additional concrete. Estimated downtime: 3 months.
With FRP Wrapping (Composite) by Cathpro Indonesia, all strengthening work was executed during night shifts and weekends, running in parallel with the production schedule. Total project duration: 18 calendar days.

Every stage is executed to ACI 440 specifications. None can be skipped — because the quality of each layer directly determines the final structural performance.
Removal of delaminated concrete (spalling) using chipping hammers, cleaning of any exposed and corroded rebar, and diamond grinding of the surface until concrete pores are fully open and the substrate is level. This is the most critical stage — FRP adhesion performance is entirely dependent on surface condition.
Patching of all voids, cracks, and honeycombed areas using structural epoxy putty. The goal is a perfectly flat, void-free substrate that eliminates any risk of air pockets interfering with FRP-to-concrete bond.
A structural epoxy primer is applied across the entire prepared surface. The primer penetrates into the concrete pores and creates a molecular adhesion bridge for the saturation resin layer that follows.
FRP fiber sheets are uniformly saturated with epoxy saturation resin, then wrapped precisely around the structure in the fiber orientation specified by the design engineer. This stage ensures zero air voids that could reduce structural capacity.
Full curing period per material technical specification, followed by application of a UV protection coat or fire retardant coat based on environmental exposure and project requirements. Final verification via pull-off test is conducted to confirm bond integrity.
Almost any concrete structural element — provided it retains sufficient baseline integrity to serve as a strengthening substrate.
We believe technical transparency is part of the service. No question is too critical to answer honestly.
There are no shortcuts in structural engineering — but there are far more efficient and intelligent ways to get there.
FRP Wrapping (Composite) is not a solution that can be carelessly executed. Its performance is entirely determined by the precision of each stage — from surface preparation through to final testing. That is precisely why choosing a specialist applicator, rather than a general contractor, is a consequential decision for your building assets.
Don't wait for cracks to widen or a safety audit to shut your facility down. Our technical team is ready to provide an initial assessment — at no cost and with no commitment required.
