Flowable structural-repair concrete with integral corrosion inhibitor


MasterEmaco® S466CI  is a rheoplastic, pourable, shrinkage-compensated repair concrete. It has a unique formulation that provides excellent bond, resistance to sulfates and chlorides, high electrical resistivity, low permeability, high-compressive strengths, and protection from corrosion.


Approximately 0.43 ft3 (0.012 m3), which will cover approximately 5.0 ft2 (0.46 m2) at a 1" (25 mm) depth before waste.


55 lb (25 kg) multi-wall bags 3,300 lb (1,500 kg) bulk bags available by special order

Shelf Life

18 months when properly stored


Store in unopened containers at 60 to 80° F (16 to 27° C) in clean, dry conditions.

Where to Use - APPLICATION

  • Horizontal and formed vertical or overhead concrete repairs

  • Bridges, parking garages, and tunnels

  • Piers, navigation locks, dams, sea walls, and other marine structures

  • Balconies

How to Apply - Surface Preparation


1. Perform surface preparation in compliance with ICRI Technical Guideline No. 03730 “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion.”

2. Remove all unsound or delaminated concrete, providing a minimum of 1/4" (6 mm) substrate profile and 3/4" (19 mm) clearance behind corroded reinforcing steel.

3. Sawcut the perimeter of the area being repaired to a minimum depth of 1" (25 mm) to prevent feather edges. Do not cut the reinforcement.

4. After removal of concrete but before placement, mechanically abrade the concrete surface to remove all bond-inhibiting materials and to provide additional mechanical bond. Do not use a method of surface preparation that will fracture the concrete. Verify the absence of microcracking or bruising in accordance with ICRI Guideline No. 03732.

5. Unless a bonding agent will be used, presoak the prepared concrete surface to a saturated surface-dry (SSD) condition.
