LOW VISCOSITY HIGH STRENGTH INJECTABLE GROUT
Product Code : 002
Brand Name : HIND ERS 21
Product Description

Hind ERS 21 is a two component solvent free low viscous fast curing epoxy resin system comprising of
component A (Resin) and component B (curing agent). It is designed especially for pressure injection into
concrete for carrying structural repairs. Hind ERS 21 is supplied in pre-measured quantities, and conforms to
BS-6319.
USES
Hind ERS 21 is ready to use for pressure injection into concrete for structural repairs. The system possess the
properties like low viscosity, non-shrink, free flowing and pourable, hence it find various usages in sealing of
crack through injection operation, in expansion joint, floor joint, pavement joint, etc.
ADVANTAGES
Hind ERS 21 is very useful in concrete such as
· It can be injected into extremely fine cracks and small cavities.
· It has high compressive strength, tensile and flexural strength.
· Excellent bonding and adhesion.
· No shrinkage during curing.
· Like all epoxy resin system it has high chemical resistance.
· Cured material is not brittle and remains slightly flexible.
· Reduce thermal expansion co efficient thus improves thermal conductivity.
APPLICATION
Surface Preparation: Before application surface preparation is important, surface should be cleaned, dry, free
from loose particles, oil, grease or other foreign materials, injection nipples are fixed in a square grid maximum
500 to 800 mm c/c depending on the cracks and nature of concrete, if required for effective treatment, the grid
may be reduced. Before the injection starts all cracks and crevices are to be sealed with Hind ERS 21 mortar
and surface sealing is to be done for other porous areas.
Mixing:
Mix 1 part by wt of component B with 2 parts by wt of component A i.e. Mixing Ratio = Component A:
Component B = 2:1 (by wt). Mix at least 5 minutes to uniform color without any steak using a drill and paddle
mixed (speed 200 RPM) so as to avoid any entrapped air. Comp B is to be poured in Comp A and stirred gently.
Injection: The grout mixture should be pumped by a positive displacement plunger type pump. Inject at slow
and even pressure through the injecting nipples till refusal or when the grout oozes out from nipple immediately
adjacent to or above the one being injected.
Cleaning:
Clean all tools & equipment immediately after use with, Xylene, Toluene or suitable solvent.
