Installation instructions for reinforced PVC swimming pool liners

This information sheet describes the installation process of a reinforced 1.5mm PVC liner designed specifically for swimming pools. This provides a basic notice for welding the On-Site ProFlex liner. It is highly recommended to have an experienced and well-reputed professional show you how to measure, weld, trouble-shoot for first time installations.
Proflex liners consist of two PVC membranes that are laminated onto a woven polyester reinforced mesh. The 1.5mm PVC sheets are cut and welded on site. When installed, reinforced PVC material gives the swimming pool an extremely strong, flexible and attractive waterproof surface for the pool walls and floor.

Preparations before liner installation:
• Provide suitable conditions, including temporary shade over the pool and/or wet-weather protection, so work can be carried out unrestricted.

• Supply and erect mandatory safety barricades, signs, lights, and equipment to protect workmen and the public.

• All pool surfaces need to be reasonably smooth without oil or tar-based material present and free of sharp projections, voids or large cracks.  Fill holes and cracks to a smooth finish.

• If the walls are made of galvanized steel, and there is red/brown rust present, it is recommended that the rust be cleaned and painted with a zinc based primer.

• Remove and vacuum away any dirt from inside the pool.

• In the event of installing the liner in an existing pool, it is very important to sanitize the walls and floor to avert the growth of mould or bacteria that can harm the liner material.

• Check that all fittings, seals, flanges, screws etc. are present and in good condition.

• Provide a suitable container for the disposal of scrap material in close proximity to pool area.

• Have a licensed electrician examine (and repair if necessary), the electrical system, including grounding of the pool, underwater lights and any other relevant electrical devices.

• Make sure that easy access to electricity is available.

• Provide a water supply for cleaning, rinsing, and filling the pool.

• Clean the area around the pool.

• If the pool needs to be drained, closely monitor the water table around the pool to minimize hydrostatic damage to pool shell.

Delivery, storage and handling
The PVC membrane should be delivered on a palette to the site packaged to prevent damage. The rolls of material should not be stacked on their end or stored in any manner that could cause damage or deformity.

Materials
• Flexible reinforced PVC liner: The liner is to be installed as detailed in the drawings. The material is usally (must not be less than 1.5 mm thick), as per the technical data sheet provided by Haogenplast.

• Flexible anti-slip PVC reinforced sheeting: This material is identical in chemical and physical properties to the reinforced PVC liner, and has an embossed surface suitable for high traffic areas.

• Geo-textile fleece underlay: If desired, the interior surface of the swimming pool can be covered with a polyester fleece underlay (separator) weighing at least 300 gram per square meter. The fleece underlay must be resistant to freeze, thaw, moisture, soil-chemical abrasion and must be free of foreign matter that could potentially damage the liner and should be flame resistant due to the high-temperature of the hot-air welding process.
Installation procedure

• Fasten the rigid PVC linerlock strip around the perimeter of the pool just under the coping stone with sunken head non-corrosive screws and anchors or aluminum rivets, at 10 cm centers.

• If using underlay, attach the fleece to the pool wall and floor with glue in order to secure the fleece. Ensure that there are no creases and the seams butt together and do not overlap.

• If fixing the wall liner to the coated steel, install PVC coated steel or shaped galvanized strips as necessary to form angles, edges, corners, or other transitions.

• There are 2 methods for hanging the wall material:

• Weld a 9 mm strip of PVC to the top back-side of the sheet as a bead to insert in the linerlock.

• The flexible reinforced PVC liner is heat-welded to a rigid PVC perimeter strip or to the PVC-coated steel strips.

• Seams are to be with a single overlap only. Multiple overlaps are not acceptable as they are susceptible to leaks.

• All material sections are to be applied in full roll widths and lengths except where pool conditions dictate otherwise.

• Align the sheets in such a way as to minimize visible seams.

• Completely replace any damaged areas with new material so that there will be no patches.

• There are 2 methods for welding all seams and joints:

1. Cold weld applying THF between the 5cm overlay using a sand-bag weight to press the sheets together. (Care must be taken to ensure that THF is not spilt on to exposed areas of the PVC sheets.)

2. Hot air welds with a minimum 5 cm overlap.

• Welding should progress at a rate of about 80 cm per minute.

• The best temperature for obtaining a perfect weld is between 450 and 500°C.  The working temperature may vary according to the weather (i.e. humidity, temperature, wind, etc).

• Do not heat-weld when the temperature is below 10°C.

• Edges must be absolutely clean and dry in order to prevent steam bubbles caused by the welding.

• Prod the seams, when cooled, with a hand-held lance to ensure that the weld is complete. Apply an adequate pressure to detect possible weak points or insufficient adhesion of the two layers.

• If necessary, re-weld the faulty seams with the hot-air welder.

• Finish off the (cold or hot weld) seam with a bead of liquid PVC compound along the edge of the seam.

• In areas such as shallow water or steps, it is recommended to weld a layer of anti-slip PVC reinforced sheeting onto the new floor or step surface.

• Affix to the liner any special markings, patterns, lines, etc. as indicated on the drawings or as specified.

• In order to ensure a watertight seal between components within the pool structure such as inlets, outlets, drains, underwater lights, skimmers, etc., it is necessary to securely join the liner to these components with corresponding rigid PVC or ABS flanges, seals and stain-less steel screws.

Cleaning
After installation is complete, sweep clean (or vacuum) all surfaces. Remove scraps, debris, and other material and dispose of in a suitable manner.
Quality control

• Limit access to the project site to minimize the possibility of damage to the liner. Materials and equipment must not be dragged across the liner surface or allowed to slide down the slopes.

• Workers must wear socks or soft soled shoes, and check for any sharp objects stuck in the sole.

• After installation, check again the integrity of all welded seams and component seals.

• Upon completion of installation and checking the seams, the pool should be filled with water to normal operating level and the filtration system operated for a period of 6 hours without evidence of water loss, beyond acceptable evaporation.

• Immediately after installing the liner, protect the pool from damage, contamination, or spillage caused by other workers within the vicinity. It is highly recommended to fill the pool immediately with water. If for some reason this cannot be done, cover the new liner well to protect it from sunlight or other damage.
