DrainPlusLiner 2.0 installed in PineGroveResort



Trelleborg’s pipe seals operation has delivered its first installation of its innovative DrainPlusLiner 2.0 for pipeline rehabilitation in North America. The company deployed its new DrainPlusLiner 2.0 to the Pine Grove Resort in Northern Wisconsin, to reline a deteriorated cast iron sewer pipe under a concrete floor, without the need to dig it up.

The DrainPlusLiner 2.0 provides a single solution that allows for up to two nominal widths of variation in the internal diameter of the host pipe. It is able to travel through 90 degree bends in the sewer and is suitable for steam-curing due to its heat resistant silicone coating. These liner characteristics provide a reliable solution when faced with relining pipes with variations in internal diameter. The option to steam cure in just 45 minutes also provides significant time and cost savings.

Hotel services went on without interruption

The installation within the hotel complex is the first of its kind in the country. All the work had to be carried out as the hotel continued its normal operations without interrupting the supply or irritating the guests.

The sewer at the Pine Grove Resort, which runs under a concrete floor, is approximately 70ft in length and ranges from five to six inches in diameter with heavy tuberculation, making rehabilitation a challenge.

The DrainPlusLiner 2.0 stretches to the host pipe’s diameter and can be accommodated without any risk of wrinkles or fins in the liner. Without the need to dig the floor up it provides a structural leak-tight rehabilitation solution.

Simon Burke, U.S. Rehabilitation Manager for Trelleborg’s pipe seals operation, says: “No-dig applications for pipe rehabilitation are growing. The liner’s ability to be steam cured means that reliability, stability and speed of installation are greatly increased. Curing in approximately 45 minutes once it has reached 176 °F / 80 °C, it offers a huge time saving compared with other systems.” 

Jeff Healy, Managing Director at installer Great Lakes TV Seal Inc., commented: “There’s been no need for any major construction or disruption to the hotel which is a major benefit.”  

Application areas

Suitable for pipes and sewers from DN 70/ 3” to DN 250 / 10”, the DrainPlus Liner 2.0 is universally applicable for vertical and horizontal pipelines. The liner only requires low pressure during installation and curing.  It offers considerably greater room for manoeuvre in the application areas, because it adapts with great flexibility to changing requirements in the pipe route. Above all: Its expansion characteristics can - unlike competing products - be precisely calculated.
