<section>\r\n <h2 class=\"section-title\">Product Overview<\/h2>\r\n <p>Dezhou Shengyuan New Materials Technology Co., Ltd. is a leading manufacturer and supplier of high-performance Geosynthetic Clay Liner (GCL), also known as Bentonite Waterproof Blanket. Our GCL is an innovative composite anti-seepage material, which is manufactured by sandwiching 100% pure natural sodium bentonite between two layers of non-woven geotextile and woven geotextile, combined with advanced needle punching technology to form a stable and durable waterproof structure.<\/p>\r\n <p>Once the bentonite particles absorb water, they will expand rapidly and form a uniform gel-like waterproof layer with ultra-low permeability, which can effectively prevent liquid leakage. Our GCL products fully comply with ASTM D5993, GRI-GCL1 and other international standards, featuring excellent self-healing ability, high tensile strength and long-term durability. It is widely recognized as the most cost-effective anti-seepage solution for global environmental protection, water conservancy, civil engineering and mining projects.<\/p>\r\n <\/section>\r\n\r\n

It is widely recognized as the most cost-effective anti-seepage solution for global environmental protection, water conservancy, civil engineering and mining projects.<\\\/p>\\r\\n <\\\/section>\\r\\n\\r\\n \\r\\n <section>\\r\\n <h2 class=\\\"section-title\\\">Key Features & Advantages<\\\/h2>\\r\\n <div class=\\\"features-list\\\">\\r\\n <div class=\\\"feature-item\\\">Super impermeability with bentonite self-healing function, automatically repair minor damages<\\\/div>\\r\\n <div class=\\\"feature-item\\\">High tensile strength and strong puncture resistance, adapt to complex geological environments<\\\/div>\\r\\n <div class=\\\"feature-item\\\">100% natural sodium bentonite, non-toxic, eco-friendly and chemically stable<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Simple and fast construction, no need for heating, welding or special equipment<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Excellent durability, anti-aging and long service life up to 50 years<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Good adaptability to foundation deformation, no cracking under uneven settlement<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Wide temperature resistance, suitable for use in extreme cold and hot climate areas<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Light weight and easy transportation, greatly reduce construction cost and time<\\\/div>\\r\\n <\\\/div>\\r\\n <\\\/section>\\r\\n\\r\\n \\r\\n <section>\\r\\n <h2 class=\\\"section-title\\\">Technical Specifications (International Standard)<\\\/h2>\\r\\n <table class=\\\"params-table\\\">\\r\\n <tr><th>Item<\\\/th><th>Unit<\\\/th><th>Test Standard<\\\/th><th colspan=\\\"4\\\">Specification Index<\\\/th><\\\/tr>\\r\\n <tr><td>Unit Mass<\\\/td><td>g\\\/m\\u00b2<\\\/td><td>ASTM D5993<\\\/td><td>4000<\\\/td><td>4500<\\\/td><td>5000<\\\/td><td>6000<\\\/td><\\\/tr>\\r\\n <tr><td>Bentonite Content<\\\/td><td>kg\\\/m\\u00b2<\\\/td><td>ASTM D5993<\\\/td><td>4.0<\\\/td><td>4.5<\\\/td><td>5.0<\\\/td><td>6.0<\\\/td><\\\/tr>\\r\\n <tr><td>Tensile Strength<\\\/td><td>kN\\\/m<\\\/td><td>ASTM D4533<\\\/td><td>\\u22658.0<\\\/td><td>\\u226510.0<\\\/td><td>\\u226512.0<\\\/td><td>\\u226515.0<\\\/td><\\\/tr>\\r\\n <tr><td>Peeling Strength<\\\/td><td>N\\\/cm<\\\/td><td>ASTM D5993<\\\/td><td colspan=\\\"4\\\">\\u22651.5<\\\/td><\\\/tr>\\r\\n <tr><td>Permeability Coefficient<\\\/td><td>cm\\\/s<\\\/td><td>ASTM D6766<\\\/td><td colspan=\\\"4\\\">\\u22645\\u00d710\\u207b\\u00b9\\u00b9<\\\/td><\\\/tr>\\r\\n <tr><td>Hydrostatic Pressure Resistance<\\\/td><td>m<\\\/td><td>ASTM D5993<\\\/td><td colspan=\\\"4\\\">\\u22650.5<\\\/td><\\\/tr>\\r\\n <tr><td>Expansion Index<\\\/td><td>mL\\\/2g<\\\/td><td>ASTM D2980<\\\/td><td colspan=\\\"4\\\">\\u226524<\\\/td><\\\/tr>\\r\\n <tr><td>Width<\\\/td><td>m<\\\/td><td>-<\\\/td><td colspan=\\\"4\\\">4.0 -

New Materials Technology Co., Ltd. is a leading manufacturer and supplier of high-performance Geosynthetic Clay Liner (GCL), also known as Bentonite Waterproof Blanket. Our GCL is an innovative composite anti-seepage material, which is manufactured by sandwiching 100% pure natural sodium bentonite between two layers of non-woven geotextile and woven geotextile, combined with advanced needle punching technology to form a stable and durable waterproof structure.<\\\/p>\\r\\n <p>Once the bentonite particles absorb water, they will expand rapidly and form a uniform gel-like waterproof layer with ultra-low permeability, which can effectively prevent liquid leakage. Our GCL products fully comply with ASTM D5993, GRI-GCL1 and other international standards, featuring excellent self-healing ability, high tensile strength and long-term durability. It is widely recognized as the most cost-effective anti-seepage solution for global environmental protection, water conservancy, civil engineering and mining projects.<\\\/p>\\r\\n

New Materials Technology Co., Ltd. is a leading manufacturer and supplier of high-performance Geosynthetic Clay Liner (GCL), also known as Bentonite Waterproof Blanket. Our GCL is an innovative composite anti-seepage material, which is manufactured by sandwiching 100% pure natural sodium bentonite between two layers of non-woven geotextile and woven geotextile, combined with advanced needle punching technology to form a stable and durable waterproof structure.<\\\/p>\\r\\n <p>Once the bentonite particles absorb water, they will expand rapidly and form a uniform gel-like waterproof layer with ultra-low permeability, which can effectively prevent liquid leakage. Our GCL products fully comply with ASTM D5993, GRI-GCL1 and other international standards, featuring excellent self-healing ability, high tensile strength and long-term durability. It is widely recognized as the most cost-effective anti-seepage solution for global environmental protection, water conservancy, civil engineering and mining projects.<\\\/p>\\r\\n <\\\/section>\\r\\n\\r\\n \\r\\n <section>\\r\\n <h2 class=\\\"section-title\\\">Key Features & Advantages<\\\/h2>\\r\\n <div class=\\\"features-list\\\">\\r\\n <div class=\\\"feature-item\\\">Super impermeability with bentonite self-healing function, automatically repair minor damages<\\\/div>\\r\\n <div class=\\\"feature-item\\\">High tensile strength and strong puncture resistance, adapt to complex geological environments<\\\/div>\\r\\n <div class=\\\"feature-item\\\">100% natural sodium bentonite, non-toxic, eco-friendly and chemically stable<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Simple and fast construction, no need for heating, welding or special equipment<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Excellent durability, anti-aging and long service life up to 50 years<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Good adaptability to foundation deformation, no cracking under uneven settlement<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Wide temperature resistance, suitable for use in extreme cold and hot climate areas<\\\/div>\\r\\n <div class=\\\"feature-item\\\">Light weight and easy transportation, greatly reduce construction cost and time<\\\/div>\\r\\n <\\\/div>\\r\\n <\\\/section>\\r\\n\\r\\n \\r\\n <section>\\r\\n <h2 class=\\\"section-title\\\">Technical Specifications (International Standard)<\\\/h2>\\r\\n <table class=\\\"params-table\\\">\\r\\n <tr><th>Item<\\\/th><th>Unit<\\\/th><th>Test Standard<\\\/th><th colspan=\\\"4\\\">Specification Index<\\\/th><\\\/tr>\\r\\n <tr><td>Unit Mass<\\\/td><td>g\\\/m\\u00b2<\\\/td><td>ASTM D5993<\\\/td><td>4000<\\\/td><td>4500<\\\/td><td>5000<\\\/td><td>6000<\\\/td><\\\/tr>\\r\\n <tr><td>Bentonite Content<\\\/td><td>kg\\\/m\\u00b2<\\\/td><td>ASTM D5993<\\\/td><td>4.0<\\\/td><td>4.5<\\\/td><td>5.0<\\\/td><td>6.0<\\\/td><\\\/tr>\\r\\n <tr><td>Tensile Strength<\\\/td><td>kN\\\/m<\\\/td><td>ASTM D4533<\\\/td><td>\\u22658.0<\\\/td><td>\\u226510.0<\\\/td><td>\\u226512.0<\\\/td><td>\\u226515.0<\\\/td><\\\/tr>\\r\\n <tr><td>Peeling Strength<\\\/td><td>N\\\/cm<\\\/td><td>ASTM D5993<\\\/td><td colspan=\\\"4\\\">\\u22651.5<\\\/td><\\\/tr>\\r\\n <tr><td>Permeability Coefficient<\\\/td><td>cm\\\/s<\\\/td><td>ASTM D6766<\\\/td><td colspan=\\\"4\\\">\\u22645\\u00d710\\u207b\\u00b9\\u00b9<\\\/td><\\\/tr>\\r\\n <tr><td>Hydrostatic Pressure Resistance<\\\/td><td>m<\\\/td><td>ASTM D5993<\\\/td><td colspan=\\\"4\\\">\\u22650.5<\\\/td><\\\/tr>\\r\\n <tr><td>Expansion Index<\\\/td><td>mL\\\/2g<\\\/td><td>ASTM D2980<\\\/td><td colspan=\\\"4\\\">\\u226524<\\\/td><\\\/tr>\\r\\n <tr><td>Width<\\\/td><td>m<\\\/td><td>-<\\\/td><td colspan=\\\"4\\\">4.0 -
