Monolithic Structural Bonding for Modern Concrete Extensions
When extending an existing building upwards or sideways—such as casting additional floors, extending cantilever balconies, widening staircases, or strengthening foundations—chipping away cured concrete to expose rusted dowel bars creates micro-cracks and compromises structural integrity.
Chemical Rebarring (Post-Installed Rebar Fixing) is the modern, code-approved engineering solution. At QuickCoreCut, we use certified pure epoxy and hybrid chemical injection resins from world-class leaders (such as Hilti HIT-RE 500 V4 and Fischer FIS EM Plus). Our certified technicians drill precise embedment holes, execute triple-phase compressed air cleaning, and inject calibrated resins that bond steel TMT bars to existing concrete with tensile strengths that often exceed the yield point of the steel itself.
Certified High-Bond Epoxy Resins
Using ETA-certified Hilti and Fischer structural epoxies rated for seismic zones and long-term design loads.
Full Range of Bar Diameters
Anchoring 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 28mm, and 32mm high-tensile TMT reinforcing bars and threaded rods.
Zero Expansion Stress
Unlike mechanical expansion anchors, chemical resins create zero radial bursting stress, allowing anchoring very close to concrete edges.
Pull-Out Test Verification
On-site calibrated hydraulic tensile pull-out proof load testing with formal test reports for structural consultants.
The 5-Step Certified Rebarring Protocol
The ultimate load-bearing strength of chemical rebarring depends 100% on rigorous installation discipline:
01
Design & Embedment Depth Calculation
Calculating exact hole diameter and embedment depth (typically 10d to 20d, where d = bar diameter) in compliance with IS 456, Eurocode, or structural consultant drawings.
02
Rotary Hammer or Diamond Core Drilling
Drilling clean, straight holes using specialized hollow drill bits or diamond core barrels equipped with automated dust extractors.
03
Compressed Air & Steel Wire Brush Cleaning
Executing the mandatory 2x2x2 cleaning cycle: twice oil-free compressed air blow-out, twice steel wire brush scrubbing, and twice final air purge until zero drilling dust remains.
04
Piston-Plug Chemical Resin Injection
Dispensing two-component epoxy through static mixing nozzles and extension tubes from the bottom of the hole upward to prevent air pocket entrapment.
05
Rebar Insertion & Controlled Curing
Inserting cleaned TMT rebar with a slight twisting motion until reaching target depth. Allowing full curing time before applying structural concrete loads.
