Introduction to the swelling degree of Gel-Fit rope (bentonite) in saltwater. Using NaCl, a solution of arbitrary salt concentration was prepared and divided into a 100ml graduated cylinder. 2g of bentonite was measured and added to the above salt solution in ten increments every 30 minutes. After allowing it to stand for 24 hours, the scale at the boundary with the supernatant was read to determine the swelling degree. As a result, the salinity of seawater is considered to be about 3%, but the salinity of landfill sites adjacent to the sea is generally thought to be around 1%, depending on the conditions, and the swelling degree is estimated to be above 15 (ml/2g). 【Overview】 <Test Content> - A solution of arbitrary salt concentration was prepared using NaCl and divided into a 100ml graduated cylinder. - 2g of bentonite was measured and added to the above salt solution in ten increments every 30 minutes. - After allowing it to stand for 24 hours, the scale at the boundary with the supernatant was read to determine the swelling degree. <Test Results> - The salinity of landfill sites adjacent to the sea is generally considered to be around 1%, depending on the conditions, and the swelling degree is estimated to be above 15 (ml/2g). *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the test results of the weight change measurement due to rainfall for our concrete joint water stop material "Gel Fit Rope." The test specimen was weighed after being immersed in water for 1 hour (L=1800mm), recreating the situation before the external formwork was installed, and measurements were taken one month after the specimen was set up. After 30 days of being left undisturbed, the weight of the specimen was 290g/m, resulting in a weight ratio of -6.45%. 【Summary】 ■ Test specimen: Gel Fit Rope, L=1800mm, weighed after being immersed in water for 1 hour (310g/m) ■ Test content: Recreating the situation before the external formwork was installed, with measurements taken one month after the specimen was set up ■ Test results: After 30 days, the weight of the specimen was 290g/m, with a weight ratio of -6.45% *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the results of the repeated weight change measurement of the concrete joint water stop material "Gel Fit Rope" conducted by our company. Starting with 1 hour of immersion, the test specimens were weighed daily and the contaminated water was replaced with clean water. As a result, a 24% reduction in weight ratio was confirmed on the 8th day (after 7 water replacements). 【Summary】 ■ Test specimen: Gel Fit Rope, L=190mm, immersed in water for 1 hour and weighed (85g–87g) ■ Test content: Daily weighing of test specimens and replacement of contaminated water with clean water ■ Test results: A 24% reduction in weight ratio was confirmed on the 8th day (after 7 water replacements) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the test results of the immersion weight change measurement of our concrete joint water stop material "Gel Fit Rope." The test involved leaving the product submerged in water and measuring its weight (measured on days 7, 14, 21, 28, and 30). After installation, in a state of water pooling (still water) within the formwork, the internal bentonite did not decrease in weight. It is believed that the bentonite that leached to the surface protected the interior, preventing any weight loss. 【Summary】 ■ Test specimen: Gel Fit Rope, L=190mm, immersed in water for 1 hour and weighed (85g–87g) ■ Test content: Left submerged in water and weighed (measured on days 7, 14, 21, 28, and 30) ■ Test results: No change in weight of the test specimen (100–105g) even after 30 days of immersion *For more details, please refer to the PDF document or feel free to contact us.

"Gel Fit Rope" is a water stop material for concrete joints. It prevents water leakage from the joints and cracks in underground concrete in construction and civil engineering by the swelling of bentonite within the vinyl mesh. In Document (1), we present the results of pressure tests conducted by our company, accompanied by photographs. Document (2) introduces the "long-term water pressure test," while (3) presents the "water pressure test based on actual site conditions."

"Gelpitatt" is a simple and reliable waterproofing putty made primarily of modified bentonite. The modified bentonite swells and gels with the water from the leak, completely blocking the water path and demonstrating excellent waterproofing effectiveness. [Features] ■ Main component: Modified bentonite ■ Simple and reliable waterproofing putty ■ Demonstrates excellent waterproofing effectiveness *For more details, please refer to the PDF document or feel free to contact us.

• Water stop

"Gelpitatt Q" is a water-stopping material used for post-construction methods in civil engineering and building concrete structures, primarily composed of modified bentonite, specifically for areas where P-con (wooden formwork) has been removed. After removing the P-con, simply fill the area with this granular product and perform a standard mortar finish to achieve an easy and reliable water-stopping effect. 【Features】 ■ Main component: Modified bentonite ■ Easy and reliable water-stopping effect *For more details, please refer to the PDF document or feel free to contact us.

• Water stop

The "Gel Ring" is a waterproofing material for the early construction method that is inserted into the separator before concrete placement. During the installation of the formwork, the Gel Ring is inserted into the separator, allowing for waterproofing at the separator section within the concrete. The modified bentonite inside the product swells and gels in response to infiltrating water, preventing water pathways. 【Features】 ■ Completion is achieved simply by inserting the Gel Ring into the separator. ■ The swelling and gelling of bentonite block water pathways and provide waterproofing. *For more details, please refer to the PDF document or feel free to contact us.

• Water stop

"Gelfit Rope" is an environmentally friendly concrete joint bentonite-based water stop material that utilizes the rapid water absorption properties of gelation from modified refined bentonite. It prevents water leakage from construction and civil engineering underground concrete joints and cracks by the swelling of bentonite within a vinyl mesh. Additionally, bentonite is a completely inorganic mineral that does not decompose, complies with the soil environmental standards of the Japanese Pharmacopoeia, and is a material that is friendly to both the human body and the environment. You can view the swelling and melting of granular bentonite on our company website on YouTube. 【Features】 ■ Environmentally friendly ■ Water stop effect ■ No harmful substances or aging deterioration ■ Can be applied after leakage occurs ■ Easy temporary fixing construction *For more details, please refer to the catalog or feel free to contact us.
