Epoxy paste grouting compound
Two-component, thixotropic modified epoxy paste.
As a grouting medium, either as supplied or converted into a mortar, for fixing dowel bars, bolts or other steel overhead or horizontally into concrete or rock. As a fast-setting non-flow adhesive. Grouting vertically downwards use epidermix® 396.
- Will not drain from hole, including overhead
- Stronger than surrounding concrete and steel
Properties of Wet Material

All surfaces must be clean, sound and dry.
Cast concrete must be free of all laitance, dust and foreign matter. Drilled concrete must be free of dust and debris and if wet-drilled must be dry and free of all traces of slurry. Any glaze caused by core drilling must be removed by mechanical roughening to ensure good bonding between the adhesive and the concrete rock surface. Close-fitting burrs attached to a long shaft mounted in a power drill will aid in this respect. Smooth steel should be abrasive blast cleaned and must be free of scale, rust and oily material. Deformed and threaded bars should be oil and grease free and preferably free of rust and scale.
Bonding / Priming
Mix both containers individually and ideally use a can opener to remove the lip of the containers. Transfer complete contents of both containers to a large clean board or plate, setting up the components side by side and not one on top of the other. Do not combine the components until other aspects of the job are ready. When ready to mix, combine the ingredients together and blend, using at least two trowels or spatula, until the compound is completely mixed. If a mortar is required, add an equivalent volume of silica grit and continue mixing until a homogeneous material is obtained.
Properties of Cured Material
|Maximum service temp||70°C|
|Compressive strength @ 25 °C||90 MPa @ 7 days|
|Solvent resistance||Resists: aliphatic solvents, vegetable and mineral oils and greases, petroleum fuels|
|Tensile strength @ 25 °C||21 MPa @ 7 days|
Grouting with epidermix® 396 – Quantity Calculations:
The quantity of grouting material can be calculated from the formula:
0,8 (D + d) (D – d)HN = liters of grout required
D = diameter of hole in cm
d = diameter of bar in cm
H = depth of hole in cm
N = number of holes
If the dimensions are taken in centimeters, dividing the answer by 1 000 will give the number of liters of grout required, at a 2:1 filling ratio, half of this volume of epidermix® will be needed. At 1:1 filling ratio, three quarters of this volume of epidermix® will be needed. These figures make no allowance for site wastage of material.
Provided deformed or threaded steel, either mild or high tensile, is embedded at least 15 diameters it can be expected that any failure of the assembly will be due to tensile rupture of the steel. Thus epidermix® grouting allows the steel to develop its full design strength. Regarding the ratio of hole to rod diameter it has been shown that the ultimate coverage bond stress is at its highest at a ratio of 1,3. This reduces as the ratio increased to 1,67 thereafter remaining constant. By increasing the ratio from 1,3 to 1,5 the ultimate average bond stress is decreased some 15%. At a ratio of 1,67 the ultimate average bond stress has decreased some 20%.
If grouting horizontally or overhead, a mastic gun is required with a length of plastic tubing of sufficient diameter to fit tightly over the gun’s nozzle. The tube must be long enough to reach the back of the hole.
Fill the gun with the mixed epoxy compound or mortar and pump material into the back of the hole, slowly withdrawing the tube until sufficient material has been deposited to fill the hole once the bar has been introduced.
The bar should be introduced with a rotary motion to ensure wetting of both bar and concrete, if it is important that the bar is truly horizontal a jig or template must be used until the com-pound has set.
Properties During Application
|Application by||Trowel or mastic gun|
|Pot life||15 °C||20 °C||25 °C||30 °C||35 °C|
|500ml||80 min||60 min||40 min||30 min||20 min|
|1L||60 min||45 min||30 min||22 min||15 min|
|Application temp range||10°C to 40°C Temperature of metal to be grouted should not exceed 25°C at time of grouting. If application temperature is above 30°C consult. a.b.e®.’s Technical Department for special precautions|
|Maximum application rate||Do not grout unfilled epidermix® 396 into a hole larger than 1,5 times bar diameter. When grouting with filled epidermix® 396 annulus width should be kept as small as possible.|
|Application rate||If mixed, unfilled epidermix® 396 will be sufficient for: 1L annulus volume. 1 L mixed epidermix® 396 filled with dry silica grit will be sufficient for 1,3L annulus volume filled at a loading of 1:1. these figures do not allow for any wastage, which can run as high as 20 – 25%.|
|Equipment clean-up||abe® super brush cleaner|
lean with abe® super brush cleaner, before the epoxy has set, after which rinse well with clean water.

Two component, low creep, structural epoxy paste grouting compound for fixing starter bars and bolts horizontally or vertically up.
The grouting compound shall be epidermix® 396, a two component, thixotropic structural epoxy compound applied in accordance with the manufacturers recommendations, a.b.e.®
epidermix® 396 is supplied in 500ml metal containers.
Handling & Storage
This product has a shelf life of 24 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.
Health & Safety
Wet epidermix® 396 is toxic but non flammable. Always ventilate the working area well during application and drying. Always wear gloves and eye protection when working with the material and avoid excessive inhalation and skin contact. If material is splashed in the eye, wash with copious quantities of clean water and seek medical attention. Cured epidermix® 396 is inert and harmless.
