High Strength Pourable / Injectable Epoxy Grout

HIGH STRENGTH POURABLE / INJECTABLE EPOXY GROUT

Hind ERS 212 is a three component solvent free, free flowing, non-shrinking fast curing epoxy resin system
used for pourable into concrete for carrying out structural repairs. The system is insensitive to water and due to
higher density it displaces the water thus making application on damp surface. The cured system possesses high
mechanical strength, non-shrinking properties, excellent adhesion, and is chemical resistant typical of all epoxy
resin system. Cracks and voids of any nature can be successfully sealed/ bonded with Hind ERS 212. Though it
has high strength, the cured material does not become brittle and remains slight flexible. Hind ERS 212 is
manufactured in pre-measured quantities. Component A- Resin, Component B-Polyamide hardener and
Component C- Special Aggregate (Graded Silica flour/sand).

ADVANTAGES
Free flowing and non-shrink system.
Resistance to acids and alkalis.
Moisture insensitive
Useful and helps rapid installation process with high strength.
Very useful in sealing wider cracks
MIX RATIO
Component A - 2 parts by weight: Component B -1 parts by weight: Component C- 2 parts by weight.

APPLICATION

Preparation of Surface
The area to be treated should be properly cleaned by wire brush. Injection ports/nozzles are fixed at a regular
spacing. The ports/nozzles to be sealed on the surface to prevent the grout from oozing out at the time of
injection operation. It can be directly poured into wider cracks to fill it by gravity.
Mixing
Component-B Polyamide Hardener and Component A Resin are mixed at first, then Component C Special
Aggregate is slowly mixed well, so as not to entrap air into the product. Mixing is done for 2-3 minutes using a
drill and paddle (maximum 200-300 R.P.M.).Only required quantity of material to be mixed for immediate use.
The mixed material should be kept undisturbed for 2-3 minutes, so that if any entrapped air is there it escapes
from the mix.

Injection
The grout mixture is pumped through the ports/nozzles fixed by means of positive displacement pump till there
is refusal from the nozzle or the mixture comes out of the adjacent nozzle.

Cleaning: Clean all tools & equipment immediately after use with, Xylene, Toluene or suitable solvent.
