Grouting Equipment for Bonded Post-Tensioning
In bonded post-tensioning systems, filling the duct with grout after stressing is mandatory. This creates structural bond between strand and concrete and provides corrosion protection.
ASZ Grup supplies grout pumps, mixers, injection hoses and connection fittings. We also provide technical support for field execution and grouting procedures.
Grouting Process
- Grout mix — Cement-based injection grout with high flowability
- Pumping — Low-pressure, continuous-flow grout pump
- Injection — Grout fill through duct ends with air venting
- Inspection — Completion check and leakage control

Frequently Asked Questions
When should grouting be performed?
Grouting should be completed as soon as possible after stressing and wedge locking — ideally the same day. Delay increases corrosion risk.
Is grouting equipment available for hire or purchase?
Rental and purchase options are available depending on project duration. Contact us for a quotation.
