Gel injection

Injection gel is a low viscosity waterproofing injection material for sealing structural elements with ground contact. Acrylic gel is a very low viscosity injection material. Its very low viscosity makes it an ideal solution for sealing structural elements in ground contact. Low viscosity injection gel is also commonly used for sealing surfaces in open porous structures against moisture exposure. The polymer waterproofing gel is also suitable for joints, dilatations and joints.

Acid, Salt and Frost Resistant Injection Gel

Acrylate gel, a fully reactive waterproofing grouting resin, is insoluble in water and fuels. Waterproofing injection gels are compatible not only with concrete and masonry mortar, but also with foil, cable and pipe insulation. They are highly resistant to acids and salts that damage the building structure. In addition, the polymeric injection gel is resistant to frost and thawing.

Application of Injection Gel

In polymer gel application, the injection pressure depends on the condition and nature of the building structure. The acrylate injection gel is injected from bottom to top, starting from the lowest drilling hole level. The injection is continued until the acrylic gel exits the side packers. The reaction rate is affected by the temperature of the material and the structural element. High temperatures accelerate the reaction, while low temperatures slow it down. Only pure water insulation injection gel, free of other impurities, is injected into the drilled holes.

Application with 2C pump (stainless steel);

Components A and B of the polymeric gel are mixed until a homogeneous structure is achieved and a sufficient volume flow is ensured. Final operation of the injection gel;
The packs are removed immediately after the injection gel injection. All gel should be removed from the drill holes to a depth of approximately 10 cm. Optionally, fast drying mortar for masonry or grout mortar for concrete and general purpose mortar is used.

Acrylate Gel Injection Resins Properties and Uses

Acrylate gels are nowadays widely used in tunnel and dam construction, mainly due to their low viscosity and good elastic properties. In fact, acrylate gel injection systems solidify non-cohesive soil, penetrating it down to the finest particles, while at the same time maintaining the elasticity of the stabilized areas. Its first-class adhesive properties combined with its adjustable reaction time make it a material that is primarily required for sealing (bonding) damaged thin metal sheet and membranes in tunneling and dam construction. The TBM tunneling and micro-tunneling sector is also an area of use for acrylate gels. It is used in waterproofing applications of cracks and joints. It is used to fill the gaps between curtains and other structural elements. It has high resistance against freezing. It has chemical resistance. It has high swelling feature. It can be applied in humid and wet environments. It has the ability to penetrate very fine cracks in order to permanently stop water leaks coming from capillary cracks in the TBM tunnel. If there is any water leakage in your pool, if your parking lot is flooded, if there is water coming from the basement floors, if you contact our Santaş isolation technical team, we will be happy to help you and solve your problem.
