Polyinject ECO
Polyinject ECO
Three-component, water-swelling hydrogel
Properties
- Low blending viscosity
- Pot life can be defined
- Elastic
Description
Polyinject ECO is a three-component, waterswelling hydrogel on acrylate or methacrylate basis that hardens to an elastic product. Polyinject ECO has an extrem low blending viscosity that is almost equivalent to the viscosity of water. Polyinject ECO is used for grout curtains, stopping of water ingress and ground stabilization. Differing pot lives can be defined (see table pot life), adapted to the application and environmental temperature, by varying the B-amount of salt (50g up to 1000 g based on 20 kg AI components).
TDS For Polyinject ECO
- Step by Step
Surface preparation
The surface must be stable and free of separating substances. Insufficiently firm layers and concrete slurry must be removed. For this purpose the surface may be prepared by suitable mechanical processes such as e.g. shot blasting, milling or any other suitable mechanical means. Blow the cracks and treated surface with oil free air to ensure complete removal of all dust and loose particles. In the presence of running water the flow must be stopped using POLYINJECT STOP which produces a rapid setting water-stopping foam. When the water is stopped the cracks are re-injected with Polyinject ECO.
Work preparation
Polyinject ECO is be applied as injection resin using injection packers and 2-C pumps equipped with a flushing unit. The injection packers may be fixed into holes drilled directly into the crack or drilled diagonally from concrete adjacent to the crack or by the fixing of injection nipples. For further assistance and instructions regarding the packer fixing and design please refer to our Method Statement.
Mixing
Polyinject ECO consists of 3 components. The AII container is poured completely into the AI container and mixed for approx. 3 minutes. The B component is filled in the desired amount into a container equivalent to the AI component and filled with clean tap water up to the same mass as AI + AII, then it is mixed again for 3 minutes. The A and B components prepared in this way are ready for use and are processed 1:1 with a 2-component injection pump equipped with a flushing unit. The A and B components prepared in this way should be processed within 5 hours. The pot life can be adjusted by the amount of component B added to the mix depending on the temperature. The amount of component B should not be below 50 g (based on 20 kg of AI-component) to assure a reliable reaction start. The amount of component B should also never exceed 1000 g (based on 20 kg of AI-component). Never mix the AI+AII mixture together with B component.
Injection
Polyinject ECO can be injected with a 2-component injection pump equipped with a flushing unit.
