Low viscosity epoxy grout & injection resin
Vetogrout ER717 is a low viscosity epoxy resin based grout for crack injection where chemical resistance and physical properties of the hardened grout is of extreme importance such as extreme industrial applications, rail tracks, dynamic load situations, chemical tanks,...etc. Vetogrout ER717 consists of two components (Base and Hardener) that are provided in the right proportions, when mixed and applied; it penetrates deeps into cracks and cavities providing a permanent seal.
- ACI 503.7: Specification for crack repair by epoxy injection
- ASTM C881/881M
- EN BS 6920 - Elevated temperatures
- Vetogrout ER717 supplied in 5 liter Kit. Coverage - 5 liter yield.
- Vetoprime EP490 supplied in 15 Liter Kit. Coverage - 5 - 7 m2 / liter.
- Vetonit Solvent XX400 supplied in 4 Liter cans. Coverage - 4 liter yield.
Original sealed containers have a shelf life of 12 months provided it is stored clear of ground in a dry shaded place below 35ºC.
The entire contents of the hardener can should be poured into the base container and mixed for 2 - 3 minutes or until uniform color is achieved. Once mixed, the material must be used within the specified pot life (see under Properties). After this time, unused material will have stiffened and should be discarded.
Note: Immediately prior to placement, all surfaces must be dry.
Ensure that the grout can be placed within its pot life. Continuous grout flow is essential. Sufficient grout must be available prior to starting and the time taken to pour a batch must be regulated to the time taken to prepare the next one.
In case of under-plate grouting, pouring should be form one side of the void to eliminate air entrapment. The hydrostatic head must be maintained at all times so that a continuous grout front is achieved.
In case of crack injection; consult your Saveto representative for a detailed method statement, onsite training and support as well as recommendation for a specialty approved applicator if needed.
Use Vetonit Solvent XX400 to clean equipment prior to material hardening, otherwise mechanical means will be necessary to remove hardened material.
Under Plate Grouting
The unrestrained surface area of the grout must be kept to a minimum. Generally, the gap between the perimeter form-work and the plate edge should not exceed 75 mm on the pouring side and 25 mm on the opposite side. Form-work on the flank sides should be kept tight to the plate edge. Air pressure relief holes should be provided to allow venting of any isolated high spots.
The form-work should be constructed to be leak proof as Vetogrout ER717 is a free flow grout. This can be achieved by using mastic sealant or a rubber gasket seal beneath the constructed form-work and between joints.
For free flow grout conditions, it is essential to provide a hydrostatic head of grout. To achieve this a feeding hopper should be used.
The substrate must be free from oil, grease, or any loosely adherent material. If the concrete surface is defective or has laitance, it must be cut back to a sound base. Bolt holes or fixing pockets must be blown clean of any dirt or debris.
If delay is likely before placing steel base plates, it is recommended that the underside and edge are coated with Vetoprime EP490 to prevent rust formation and ensure bonding with the Vetogrout ER717 All metal surfaces should be cleaned to a bright finish in accordance with Swedish Standard SA 2 ½ or equal. Vetoprime EP490 can be applied directly onto newly cleaned steel surfaces even if they are damp.
All cracks must be chased and open to a 2 mm thickness (width generated by a saw blade).
Remove laitance and roughen 2 cm on each side of the crack using a hand grinder and clean the surface and the crack using compressed air.
Depending on the injection method (surface nipples or injection packers); the surface nipples are to be fixed on crack face using Vetorep ER350 (a twin-pack epoxy putty and leveling compound) prior to sealing the crack surface with Vetorep ER350, or directly seal the crack surface prior to drilling injection holes at 45 degree angles on the sides of the crack.
Epoxy resins can cause irritation to some people and therefore avoid direct contact with eyes or skin. It is recommended to use protective gloves and goggles during application. In case of contact with eyes, clean immediately with plenty of clean cold water and seek medical advise, if irritation persist.
Vetoprime EP490 and Vetonit Solvent XX400 are flammable.
