How do I choose the correct concrete repair product?
Product selection depends on the defect type, repair depth, crack condition,
substrate strength, reinforcement condition and structural requirement.
What is used for old-to-new concrete bonding?
Epoxy, acrylic or SBR-based bonding agents may be used depending on the application
and project specification.
What is the difference between repair mortar and grout?
Repair mortar is generally used to rebuild damaged concrete sections.
Grout is typically more flowable and used to fill gaps, voids or areas beneath base plates.
Do you supply Fischer and Hilti chemical anchors?
Yes. Injection-type chemical anchor cartridges are available in both brands, along with
mixing nozzles, hole-cleaning brushes and blow-out pumps. Share the bar size and hole
depth for the correct cartridge and quantity.
What is rebar dowelling or post-installed rebar?
It is the method of bonding a reinforcement bar into a hole drilled in existing concrete
using an injection resin, instead of casting the bar in at the time of the original pour.
It is commonly used to tie a new slab, beam, wall or staircase into an existing structure.
How is an injection chemical anchor installed?
Drill the hole to the specified diameter and depth, clean it thoroughly by brushing and
blowing out the dust, inject the resin from the base of the hole outwards to avoid trapping
air, insert the bar with a twisting motion, then leave it undisturbed for the full cure time.
Incomplete hole cleaning is the most common cause of reduced anchor performance.
When is a chemical anchor better than a mechanical one?
A chemical anchor bonds along the full embedment rather than expanding against the hole wall,
so it does not introduce splitting forces. That makes it suitable close to a concrete edge,
at reduced spacing, and for post-installed reinforcement. Final selection is a design decision.
Can cracks be repaired by injection?
Compatible cracks may be injected using epoxy or polyurethane systems.
The correct material depends on whether the crack is dry, structural or water-bearing.
What is carbon-fibre strengthening used for?
CFRP plates or fabrics are used in designed strengthening systems for beams,
slabs, columns and other structural members.
Do you supply anchor-bolt fixing products?
Yes. Polyester, epoxy-acrylate and epoxy anchoring products may be supplied
for bolts, dowels and reinforcement fixing.
Do you provide pressure-grouting equipment?
Manual and mechanical pumps, packers and compatible accessories may be supplied,
subject to project requirement and availability.
Can damaged reinforcement be protected before repair?
Yes. Compatible rebar primers and corrosion-protection systems are available
for properly prepared reinforcement.
Can you help estimate repair quantities?
Yes. Share photos, dimensions, repair depth and project location for an initial estimate.
Structural repairs may still require consultant or engineer approval.
Is bulk delivery available?
Bulk and contractor supply is available across Kochi, Ernakulam,
Thrissur and surrounding project locations, subject to stock and delivery planning.
