The PVC flashings at the edges of the roof and penetrations are heat-welded as well. Special hot air welding tools heat the edges of two pieces of the PVC roofing material to around 1,100°F, and they are pressed together with a roller to create a bond at the seams. Mechanically attached systems are cheaper, but more appropriate for large commercial roofs. I believe fully adhered systems should always be used in residential roofing applications. First of all, you should look for contractors who specialize in PVC membrane roofing to install (or repair) your PVC roof.
Key ASTM Standards for HDPE Geomembranes
PVC membrane pool liners are lauded for their flexibility and stretchability, which enables them to conform to the contours of the pool structure with ease. This flexibility allows for seamless installation around steps, corners, and other challenging areas, resulting in a smooth and uniform finish. Additionally, the stretchability of PVC membrane liners enables them to adapt to fluctuations in temperature and water levels without compromising their integrity.
- Clean installation, with no noise and in half the time it takes to install other liners.
- Other thicknesses and attachment methods have other life expectancies and warranty lengths.
- HDPE liners contain solutions down to a pH of 2 without chemical or physical damage.
- Vacuum forming, however, is more appropriate for producing parts with simpler shapes.
Pool Liners
The stable construction allows for the press frame to be clamped with only 2 clamping levers, thus saving time and unnecessary movements. The project specifications called for 80 mil smooth HDPE geomembrane along with a leak detection system. With limited movable swimming pool floors on site, the lagoon needed to be excavated deep into the ground.
What is the difference between geomembrane and HDPE?
Modern calender trains operate with computerized control systems to ensure optimum quality. In calendering, it is necessary to preflux compound on Banbury/roll mill equipment at a rate to match the calender’s capacity. A short-barreled extruder downstream of the mixing equipment is often used to screen out any possible foreign contaminant which might damage the calender rolls. The neutral PVC surface does not alter water chemistry like plaster, grout, concrete, and other porous surfaces, providing ongoing savings in operational costs. By creating a watertight lining, our membranes reduce water lost through leakage and save energy and chemical use. Natatec®, a multi-faceted and sophisticated installation technology system, comprises of a dense, high-quality, dual-layered PVC membrane material that is specifically designed for commercial pool applications.
- Nowadays, it is the most advantageous system in the market and the one that presents the fewest problems.
- On top of their physical durability, PVC geomembrane liners also have a strong resistance to chemicals.
- By preventing water leakage, these liners conserve water, a vital resource, especially in water scarce regions.
- Here are a few important things you should know about a PVC roofing membrane.

This guide covers the key considerations in selecting, specifying, and installing HDPE geomembrane liners for long-term containment performance. PVC geomembranes, for example, require extensive protection from UV when installed in the field and during use. With HDPE, containment systems can be confidently designed for decades of solar exposure. A key benefit of HDPE over other geomembrane materials is its resistance to damage from exposure to ultraviolet (UV) radiation from sunlight.

In addition to surface damage of the liner, PVC membranes are prone to growing bacteria, mold, and fungus in between the liner and pool shell surface. Pinholes in the PVC or failed seams allow the mold to contaminate the pool water, as well as allowing water to infiltrate behind the liner causing it to “balloon”. This will cause the pool shell to deteriorate, crumbling underneath the existing liner. In addition, liners cover up expansion joints so that caulking cannot be maintained, potentially permitting ground water to enter. Calendering is used to produce flexible and rigid sheeting in the 2 to 35 mil thickness range. It is a large-volume processing method that requires high capital equipment costs compared with extrusion methods.
following the Proper Steps for HDPE Liner Installation
As mentioned earlier, these liners are designed to last up to 50 years or more with proper care. You won’t ever have to worry about loose tiles or trying to repair cracks in your concrete or plaster. website for spending money on vinyl liner replacements is also eliminated by choosing to use PVC liners for your inground swimming pool. All of these different benefits make PVC liners a great selection over other available choices. Continually performing maintenance on your swimming pool requires a lot of time, and it isn’t always a fun experience.

This includes UV resistance, which can be incredibly useful for protective liners that will be exposed to the elements. Concrete protective liners have minimal lateral movement, which is necessary for ensuring the protection of the concrete structure and maintaining a leak-proof seal. Each of these materials offers specific characteristics that make them suitable for particular applications in thermoforming.
