GEO HD is the most commonly used HDPE geomembrane since they are the preferred project lining material. Hyma’s GEO HD meets and usually exceeds the international standards of GRI GM13. GEO HD has high mechanical properties with excellent resistance to many solvents, and it can withstand high temperature, that’s why it is widely utilized in multiple applications.
Hyma’s GEO HD Premium geomembrane liners are the highest-strength and most chemically resistant geomembrane on the market. These high-strength liners were developed to contain and protect against acids, oils, methane and alkalis. Across the world, Hyma’s Premium geomembrane liners are being used for pond liners, secondary containment, floating covers and wastewater baffles.
GEO HD X is ideal for applications requiring moderate chemical resistance and strength. Backed by more than 40 years of state of the art plastic technology, X is a lightweight geomembrane that utilizes the same basic technology discovered in GEO HD/LD series. While GEO X is a versatile and economical material frequently found in apps for municipal wastewater containment and stormwater runoff.
Hyma’s GEO HT are specially engineered HDPE geomembranes that are able to retain their mechanical and physical properties when exposed to temperatures up to 212°F. It is an innovative formulation that takes advantage of the high temperature performance of revolutionary resins and the thermal stability of our manufacturer’s proprietary stabilization package. High temperature geomembranes provide enhanced mechanical performance and improved chemical stability at elevated temperatures in addition to the traditional properties of polyethylene geomembranes.
LLDPE Geomembranes are commonly used in applications that require high flexibility. Hyma’s GEO LL meets and usually exceeds the international standards of GRI GM17. GEO LL offers great flexibility, outstanding resistance to low temperature and UV exposure. Also, a greater stress crack resistance than that of the HDPE.
Hyma’s GEO LL Premium geomembrane liners are the finest version of LLDPE Liners. With the addition of selective antioxidants, results in a material that resists punctures and immediately stops tears. These liners are being used for Waste Lagoons, Floating Covers, Tunnels, and Remediation.
GEO LL X is ideal for applications requiring moderate chemical resistance and strength, along with premium flexibility. X is a lightweight geomembrane that utilizes the same basic technology discovered in GEO LD series. While GEO X is a versatile and economical material frequently found in apps for municipal wastewater containment and stormwater runoff that requires high flexibility as a primary feature.
Hyma’s Construction is an LDPE film made of pure virgin materials to be used as a cover or a vapor barrier. It is an ideal solution for moisture control in different applications including concrete roads, airport runways, pools, tunnels and bunkers.
Hyma’s Welding Rod is used for joining the liners by extrusion or by adding melted material (solder). It has a polyethylene based formulation giving it a high welding ability and good compatibility with all types of Geomembranes produced by Hyma.
Hyma’s GEO Lock is an HDPE structure that acts as a crackerjack to attach Hyma’s Geomembrane to concrete, enhancing mechanical properties by providing maximum anchorage. GEO Lock is has a 3 parallel T-anchors arrangements to be inserted into the wet concrete for mechanical anchorage. Hyma’s GEO Lock is made of pure virgin HDPE to be compatible with Hyma’s Geomembranes.
Hyma’s GEO Sleeve is a PE tubular film of low-density polyethylene slipped over and fitted to a pipe at the time of laying. It is used to supplement the basic pipe coating in certain cases of highly corrosive soils, or in the presence of stray currents.
