Specifications

Excellent permeability It is easy to permeate into the fine air gap or any kind of soil due to the very low viscosity near the water density.
Impermeable layers The highly elastic and flexible gel formed after condensation has the swelling power when in contact with water by absorbing vibration and the elastic reaction to the secondary deformation of ground and structure resulting in continuously maintaining water barring capacity
Excellent workability It is possible to freely respond according to the site condition and injection objective because it has a wide range of controlling the curing time.
Non-toxic environment - friendliness It is long safe to all sorts of chemical environment of underground water and ground as it is not decomposed and leached by alkali, acids, organic chemicals.
Adhesion It maintains the waterstop effect for a long time due to excellent properties of high elasticity and high adhesion
Stability It exhibits no leaching phenomena, the weak point of the existing water glass, and no hydrolysis senile change.

Application site

It can be used for stopping water for leakage of all sorts of architecture, civil structure.

Example of Diagram for Backface Injection method

This method is the one to stop water by forming a non-permeable wall on the back face of concrete wall. It is to inject DH Acrylic Seal after boring the concrete with leaking parts, which forms a nonpermeable water stopping wall in an air gap between concrete and soil.

Classification	Contents
Characteristics	- It is effective for injecting into concrete laid part, sheet surface damaged part, joint part, and back face, and it is possible to stop water regardless of any leaked quantity. - It is suitable for stopping water for leaking parts with many fine cracks. - It is suitable for stopping water for joint leaking parts.

DH Acrylic Seal of Backface injection method

DH ACRYLIC SEAL forms a stopping wall as it sufficiently penetrates into all cracks by injecting and penetrating into the range with a radius of 60cm when installing the injection openings with distance of 100cm according to the cracks due to its equal penetration from the opening.
