Product Description

GCL Introduction

 Product introduction
Bentonite waterproof liner (GCL) is a new geosynthetic material. Taking natural sodium bentonite as material, bentonite particles are fixed between two layers of geotextile by special process to make bentonite waterproof blanket, which not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance.
O Product features

• It has excellent water swelling property and strong compactness;
• Durable waterproof performance, green environmental protection;

. With the functions of separation, reinforcement, protection and filtration, the construction is simple.

GCL Specification 

Notes
1 Bentonite property tests performed at a bentonite processing facility before shipment to INNO GCL production facilities.
2 Bentonite mass/area reported at 0 percent moisture content.
3 All tensile strength testing is performed in the machine direction using ASTM D 6768. All peel strength testing is performed using ASTM D 6496. Upon request, tensile and peel results can be reported per modified ASTM D 4632 using 4 inch grips.
4 Index flux and permeability testing with deaired distilled/deionized water at 80 psi (551kPa) cell pressure, 77 psi (531 kPa) headwater pressure and 75 psi (517 kPa) tailwater pressure. Reported value is equivalent to 925 gal/acre/day. This flux value is equivalent to a permeability of 5x10^-9 cm/sec for typical GCL thickness. Actual flux values vary with field condition pressures. The last 20 weekly values
prior the end of the production date of the supplied GCL may be provided.
5 Peak values measured at 200 psf (10 kPa) normal stress for a specimen hydrated for 48 hours. Site-specific materials, GCL products, and test conditions must be used to verify internal and interface strength of the proposed design.

 Installation Instructions

2 Before laying the bentonite waterproof blanket (GCL), there should be corresponding qualified acceptance documents for the preliminary project.
3 Before cutting the bentonite waterproof blanket (GCL), the relevant dimensions should be accurately measured, and then cut according to the actual terrain, and numbered piece by piece. The relevant information should be recorded on a special form. Laying bentonite waterproof blanket (GCL)
It must be dry and tidy, and no oil stains, splashed chemicals or chemical spots that damage the bentonite waterproof blanket (GCL) should be allowed on the surface.
4 Bentonite waterproof blanket (GCL) cannot be constructed in rainy weather and when there is water on the ground. To
5 In order to enhance the friction, the fiber of the waterproof pad is laid facing the base surface.
6 When laying the bentonite waterproof blanket (GCL), the joints should be minimized, and the raw materials should be saved as much as possible under the premise of ensuring the quality.
7 When laying the bottom surface, it should be overlapped in parallel, but not in parallel. The cloth surface should not be stretched too tightly or folded, and should be loosened appropriately and close to the ground;
8 When laying GCL when it encounters through parts, double-layer GCL waterproof pads should be laid within 500mm of the through objects. At the contact parts between GCL and the through objects, the upper and lower layers of GCL form a bell mouth, and the distance between the contact line and the through objects is at least greater than 50mm, GCL oblique mouth length is about 100mm, the gap between the two pads is filled with bentonite powder (it can also be filled with bentonite cement), and the joint between the upper layer of small waterproof pad and the lower layer of the entire waterproof pad should be glued and reworked. Fixed treatment
9 During laying, if the waterproof pad is damaged, apply a waterproof pad larger than 300mm around the damaged gap to cover it before fixing it;
10 When laying, if it rains, use plastic film material or rain-shielding material to quickly cover it. When the rain is heavy and the bentonite swells more than 300%, it should be re-laid;
11 When laying, it is strictly forbidden to put open flames or cigarette butts on any side of the waterproof pad.
Three, fixed
1 When laying, shop from top to bottom, and the direction of overlap is adapted to local conditions. Lay along the slope, and the joints must be parallel to the slope line and not intersect with the slope line.
2 In the deformed areas at the corners, the length of the joints should be as short as possible. At the toe of the slope or the place where the stress is concentrated, the horizontal joint distance must be greater than 1.5 meters. Except for special requirements, there should be no horizontal angle within 1.5 meters from the top of the slope or the stress concentration area on a slope with a slope greater than 1:6 Small 45°C seams.
3 When laying the Bentonite Waterproof Blanket (GCL), do not let stones, etc., which may damage the Bentonite Waterproof Blanket (GCL), or make the subsequent connection difficult, enter the Bentonite Waterproof Blanket (GCL) or under it.
4 On the slope surface, one end of the bentonite waterproof blanket (GCL) must be anchored, and then the coiled material must be put down along the slope surface to ensure that the bentonite waterproof blanket (GCL) remains tight. All bentonite waterproof blankets (GCL) must be pressed with sandbags, which will be used during laying and will be retained until the layer of material on top of laying.
5 After laying the bentonite waterproof blanket (GCL), it should be permanently anchored in time.
6 Sufficient temporary ballast (such as sandbags) is required during construction to prevent laying bentonite waterproof blanket (GCL)
Blowed by strong winds, the pressing materials used must be materials that will not damage the bentonite waterproof blanket (GCL), and retain them until the layer of material is laid.
7 While laying the bentonite waterproof blanket (GCL), the installation unit must take all necessary measures to prevent damage to the underlying material.
8 After installation, visually inspect the surface of all the bentonite waterproof blankets (GCL), mark and repair all the damaged areas, and make sure that there are no foreign substances, such as stones, that can cause damage to the paving surface. To
