Concrete Embedment Liners are thick sections of HDPE with a number of studs protruding from one side. The embedment liner is fastened to the inside of forms before concrete is poured to create a surface that is lined with plastic. The concrete flows around the studs anchoring the sheet firmly in place. The studs securely fasten the sheeting to the surface of the concrete. The result is a protective coating of polymer with very high pullout resistance. Concrete Embedment Liners are ideal for protecting concrete from harsh environments.
The thick sections of polymer are resistant to most acids, bases, hydrocarbons, vapors and microbiological materials, which can degrade concrete over time.
HDPE geomembrane liners are the preferred product for lining projects. HDPE liners are resistant to many different solvents and are the most widely used geomembrane liner in the world. HDPE liners is a membrane that is flat on both sides. HDPE geomembrane liners has a low coefficient of friction and can be easily cut, machined, welded, and thermoformed for easy fabrication. It used for complex shaped products such as fuel tanks, trash containers, dump carts, pallets, agricultural tanks, highways barriers and water and waste tanks
Textured HDPE Geomembrane developed with single-sided textured surface improve friction between two layers. Textured HDPE Geomembrane has a rough surface which can highly improve the friction coefficient which fits more suitable for steep slope and vertical engineering design work which maximize the effective volume of geomembrane.
Textured geomembrane is made of with advanced manufacturing equipment and professional production technology. Our high-density polyethylene textured geomembrane exhibits superior shear strength and the highest multi-axial performance which features superior high shear strength, big friction angles, outstanding elongation, and highest interface surface friction coefficient. Our Textured HDPE Geomembrane is widely applied for such projects which need increased frictional performance, flexibility,
and elongation between two layers and high steeper slopes as landfills, mining, retaining backfills and waste containment.
A HDPE version of our T-Lock offering outstanding chemical and physical resistance. Sheets are joined together by an extrusion process using molten HDPE welding rods.
The high chemical resistance of HDPE, along with proven welding and testing systems, ensure that sewerage treatment plants, pump stations, manholes, precast reinforced concrete pipes and other concrete structures, which operate in chemically aggressive environments, are provided with long term protection against corrosion. Additional benefits, like raised carrying capacity, through a low friction coefficient, when used for liquid conveyance, make this a cost-effective solution for a wide variety of lining applications.
A studded version of our HDPE T-Lock that allows for better concrete flow around the studs make this product ideal for reverse lining applications.
The membrane is placed with the studs facing the concrete structure, typically reservoirs, water tanks, or for sewer rehabilitation, and either an epoxy grout or non-shrink grout, depending on the project requirements, is injected in between the membrane and the structure, allowing the membrane to be fully attached to the structure. Joints are sealed by using an extrusion welding process.
T-Lock Plastic sheet is a T-ribbed membrane that is flat on one side, while the reverse side contains parallel T-Shaped ribs. These ribs are cast into concrete at the new construction stage, thus isolating the concrete from the harmful effects of corrosive chemicals.
The evolution of the T- Lock Linings represents a major breakthrough in physical properties, with elongation at break point being to the order of 600% for polyethylene T-Lock lining will therefore not crack when placed under stress, like coatings and they will endure for over 50 years in the toughest of service.
The V-Lock sheet liner has 2 splayed studs, each one 15 mm in length and joined by a cross bar in a V arrangement. The double stud unit is formed during the extrusion process and it is integral to the sheet itself. The stud units ensure perfect embedment of the sheet liner to concrete after casting.
