Product Description

Epoxy Resin DH-200W Grouting for Wet

EXPLAIN

DH-200W wet injection provides superior adhesive strength to wet or damp concrete structures. The low viscosity type injection material is easy to be injected to very small cracks. Once hardened, the material shows superior strength without any contraction.

PULPOSE

It is intended as grouting material for steel plate reinforcing and crack repairing of all types of concrete structure without vibration.

FEATURE

Perfect injection is possible to the end of minute cracks of concrete thanks to its low viscosity and minimized surface tension which makes easier the infiltration into the minute cracks or the base members of the structure.

It is a fast-hardening type of grouting material designed for easy application to wet surface and for no shrinkage after hardening. It has the optimum level of viscosity and fluidity for grouting work by high pressure and low pressure injectors.

The excellent adhesive strength of epoxy resin ensures that the hardened composition maintains a sufficient adhesive strength for the cement mortar, concrete and reinforcing bar etc. and does not produce de-lamination from the base member of the structure.

After epoxy resin is injected, the fully hardened composition does not create any chemical action on the reinforcing bars or concrete structure, and offers an outstanding durability by preventing corrosion.

Compared to cement mortar or concrete, it has higher mechanical strength in all respects including compressive strength, bending strength and tensile strength etc. and therefore widely used for repair and reinforcement of the concrete structures.

APPLICATION

The treatment of concrete surface can be another way of securing durability and water-tightness for those cracks that have width of below 0.2mm, but it is used for the job sites where surface treatment and filling methods cannot prevent any water leakage from cracks, corrosion of reinforcing bars and carbonization etc. Main applications are as follows.

Grouting of cracks on dried and wet concrete structure.

Grouting of gap produced by dried and wet concrete plastering mortar and tile etc.

Grouting reinforcement of aged, weakened parts of concrete.

Grouting for repairing of cracks on the dried and wet concrete molding products.

Reinforcement of anchors of dried and wet slab, column and upper plate.

Secondary grouting reinforcement after foam resin is injected.

Lower coating for working on wet floor.

Pot Life the period of time during which you can work without a change in viscosity after resin and hardener are mixed.

Tack Free the state of hardening in which you can lightly touch the mixed resin with your hand, but the hardened material does not stick.

Hardening Time the time it takes for the mixed resin to be hardened enough to realize about 80% of final mechanical strength.

MATERIAL

1. Reinjector is a mid-low pressure injecting device, upgraded to improve the effectiveness of grouting for crack repairing by incorporating the merits of the high pressure grouting of packer and the merits of syringe injector.
2. Syringe injector is a low-pressure, low-speed grouting device. A syringe injector containing the resin is set on the cracks and the resin is slowly injected with the help of resilience of the rubber band.
As explained above, you can employ various kinds of methods by using numerous grouting devices. The following work guidelines are based on the syringe injector, the representative low-pressure grouting method. You are free to change the materials depending upon the site condition. Please refer to the reinjector method and packer grouting method to learn how to use.
