Usually, the carrier is made of polymer unwoven fabric (PA, PAN, PET, PP). Membranes can be used depending on the requirements of individual producers of pipe liners.

After that the pipeline is inspected with a remote controlled camera. The analysis of the video from the sewer inspection forms the basis to create a detailed computer report on the technical condition of the pipe. On the basis of report data the sewer is classified depending on its technical condition.<\/p>\n<p>SELECTING THE REHABILITATION METHOD<\/p>\n<p>Depending on how the sewer is damaged or destroyed, and its classification to a specific group, an appropriate rehabilitation method is selected. After the evaluation of the sewer\u2019s technical condition one should analyze geodetic data, groundwater level with respect to the base of the sewer, road traffic exposure, and other factors that have influence on the selection of parameters of the used liner that is to be used, and on the basis of the above select an appropriate CIPP pipe during the design phase. On the basis of the known Young (E) modulus, specific for the proposed carrier, the designer selects the thickness of the CIPP liner.<\/p>\n<p>SATURATION OF THE PIPE LINER<\/p>\n<p>Using negative pressure the pipe liner is saturated with resin in controlled conditions.<\/p>\n<p>TRANSPORTATION TO THE CONSTRUCTION SITE<\/p>\n<p>The resin-saturated pipe liner is delivered to the construction site in containers or boxes that ensure optimal temperature conditions for the specific resin. There is no need to transport pipe liners saturated with epoxy resin (EP) as saturating equipment is located directly next to the construction site.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_custom_heading heading_semantic=&#8221;h3&#8243; text_size=&#8221;h3&#8243;]INSTALLATION[\/vc_custom_heading][vc_column_text]Once the damaged section of sewer is taken out of service a protective sleeve (preliner) is pulled into it.<br \/>\nHaving protected the surface of the host sewer a standpipe or inversion drum is placed above the place where the pipe liner will be inserted. The pipe liner is inserted into the sewer using the water inversion method.<br \/>\nOnce the above has been completed the heating unit is turned on and heats water in closed circulation inside the pipe liner up to curing temperature.<br \/>\nAfter the installation, a milling cutter is used to cut off the ends in the upstream and downstream inspection chambers, as well as \u201cblank\u201d openings for connections in the cured pipe.<br \/>\nDuring the installation process several parameters are recorded, namely: pressure of the liquid pumped into the pipe liner during all the stages of the process and curing, as well as continuous temperature readings from all control points during the curing process.[\/vc_column_text][vc_custom_heading heading_semantic=&#8221;h3&#8243; text_size=&#8221;h3&#8243;]CONTROL[\/vc_custom_heading][vc_column_text]<strong>CCTV INSPECTION<\/strong><\/p>\n<p>Once the installation is finished and house drains are opened a CCTV acceptance inspection is made and recorded on a DVD or another storage medium.
