Sikagard-694 FI — Flowable Epoxy Putty for Deep Void Filling and Honeycombed Concrete Repair (16 kg)

Surface voids and honeycombing in concrete are not always shallow enough for a knife-grade putty to fill completely. When voids extend deeper into the concrete mass — interconnected honeycombing behind a column face, deep blow holes, or voids in confined formed sections — a trowel-applied putty fills only the surface opening while the void behind it remains empty. The result is a cosmetically filled surface with an unfilled void beneath it — one that will crack through under load or thermal movement, allow moisture to accumulate behind the repair, and eventually cause the surface fill to pop out.

Sikagard-694 FI from Sika India Pvt. Ltd. is a flowable epoxy putty engineered for deep void filling and honeycombed concrete repair where a knife-grade material cannot penetrate to the full depth of the defect. The flowable consistency allows it to be poured or injected into voids — flowing under gravity or light pressure to fill the complete void volume, reaching the back wall of the defect and filling the interconnected pore structure of honeycombed concrete before curing to a hard, dense epoxy fill throughout the full depth of the repair.

The cured epoxy fill bonds strongly to the surrounding concrete, resists chemical attack and moisture penetration, and provides a structurally sound filled section that supports the surface coating or finish applied over it without the risk of subsurface voids causing delamination or surface failure over time. The flowable nature also makes it suitable for void filling beneath base plates, in confined precast sections, and in any concrete element where access for trowel application is restricted but the void needs to be completely filled.

For coating applicators, waterproofing contractors and concrete repair specialists working on concrete surfaces with deep voids or extensive honeycombing where surface-applied putties cannot achieve complete fill — Sikagard-694 FI delivers the flowable epoxy putty performance that deep, complete void filling demands.

A construction chemical repair solution from Sika for concrete void filling where depth matters as much as surface — Sikagard-694 FI is the flowable epoxy putty specification for deep void and honeycombing repair where surface fill is not complete fill.
