Geosynthetics Storage – It Matters!

Some geosynthetics are manufactured to withstand long term exposure to the elements, extreme temperatures, and puncture resistance. With this is mind, proper on-site material storage prior to installation is still critical. This small step can help ensure your liner materials are useable, damage free and able to live up to expectations when it comes time for installation.


Element Elimination

Degradation of geosynthetics can come from a variety of natural factors. Some products, such as PVC Geomembrane and geotextile, are excellent for use in buried applications and are not formulated for extended UV exposure. Over time, sunny conditions can degrade the quality of the product; potentially impacting their long-term performance. Moisture is also a consideration for geosynthetics such as Geosynthetic Clay Liner (GCL). It is essential that rolls of GCL and similar materials be kept dry prior to installation, as premature hydration may result in unusable product. Another consideration is that extra moisture can create excessively heavy rolls of material which have the potential to be very dangerous and difficult to work with for crews on-site.

Temperature Tango

Another potential damaging factor to pre-installed geomembranes and seaming materials is extreme heat and cold. Geosynthetic materials such as PVC are not invented to be exposed to extreme cold unless they are held in place and protected by soil or water. If material storage must be done in cold temperatures, it is essential that they are kept in-place as the potential of cold cracking and damage to the liner is heightened. Extreme heat can also cause materials such as Polyethylene to break down and reduce their strength properties. Many geomembrane seaming products including adhesives, primers and tapes are also sensitive to large temperature swings. For best results, they should be kept in temperature-controlled storage until use.


Physical Problems with Material Storage

Geosynthetic lining materials left unprotected on site for an extended period can also sustain physical damage from a variety of sources. Biological threats, such as animal disturbance and punctures via large sticks and trees can be the result of improper material storage. Mechanical threats from moving equipment on-site can also cause considerable damage to unprotected geosynthetic materials before installation. When possible, have materials offloaded in the location they will be stored until deployment. This can help reduce the amount of handling and risk of damage.

Another factor to consider when storing Geosynthetic materials on-site is proximity to the working area. Consider designating the liner storage area to a location adjacent or very close to the project. The less distance required to move material with heavy equipment, the lower the chances are of damage during transport to deployment.

Keeping geosynthetic materials high and dry prior to installation is also a critical part of creating a quality end product. If rolls of liner are left sitting in wet clay or mud prior to deployment, additional cleaning will be required prior to seaming. Welding anything but debris-free and dry geosynthetic materials inevitably result in QC issues. Protecting materials so that they are clean upon deployment will save precious time and money on your installation.

50mm 75mm 100mm height HDPE geocell for driveway

50mm 75mm 100mm height HDPE geocell for driveway Geocell for Driveway   Description: Geocell was used on the civil engineering community in the early 1980’s. In the commercial market, geocells solve many site problems – from steep slopes to shorelines and channels to multi-layered vegetated retaining walls, mining, oil & gas, and wind access roads, railroads, ports, dams and landfills. When filled with granular materials, Geocell   creates a three dimensional erosion barrier and structural bridge that uniformly distributes weight-bearing loads. The cellular nature of Geocell enhances drainage and prevents build-up of hydrostatic pressure. HDPE geocell   Application: 1.stabling railway/driveway bed 2.Stabling road soft ground treatment 3.withstanding lad capacities guard against the retaining wall 4.shallow water river courses to govern 5.pipelines and sewer's structural supports 6. prevent the landslide and the load bearing gravity mixed style retaining wall 7.independent walls

Geo Liners for Decorative Ponds

Geo liners for decorative ponds help to enhance the beauty and value of your property. Whether the pond will be for aesthetics, attracting wildlife, fishing, or lacing up your skates in the winter; there are many factors to consider when designing and building your dream pond.   Area and Depth Depending on the climate and intended use of your constructed pond, depth may be more of a factor than most people realize. If the pond will be constructed in a climate with four seasons and is intended to maintain fish stock; certain areas, depths, and slopes are suggested to allow aquatic life to thrive. For a vibrant fish population or cool swimming hole, a minimum pond area of 1/2 to 1 acre is recommended, with as much as the pond as possible reaching a depth of 15 feet and side slopes at 1:3 for fish habitat and 1:4 for swimming access. This combination of depth and relatively steep side slopes help reduce aquatic plant growth. An irregular shoreline is also helpful for fishery habitat. If

Freshwater Aquaculture and Geomembrane Liners

Recent concerns and regulations regarding wild harvesting and marine populations have pushed aquaculture to the forefront of the field of providing fish and aquatic life to meet growing demand. The idea of raising and rearing fish, shellfish and other aquatic organisms in a controlled environment appeals to many because of the amount of oversight that may exist in such a space. However, aquaculture operators who wish to undertake or expand their foothold should ensure that their plans include environmental considerations and the proper use of   geomembrane liners .   Aquaculture Aquaculture is defined as the propagation, rearing and harvesting of organisms in all types of water environments. This includes algae, fish and shellfish, such as shrimp. The increased market demand for seafood, coupled with technological developments, has created a growing interest in aquaculture. Aquaculture products can be used for food or other commercial products, to replenish wild populations, or to rebu
