: Lateral: Shorty™
Key Features
LMK's T-Liner® Shorty™ system is a one-piece, structural, stand-alone homogenous Main/Lateral CIPP connection liner that extends 3 feet up into the lateral pipe. Shorty™ was designed for municipalities that want the connection sealed and the most value without the cost or legal issues associated with installing a cleanout. Shorty™ is the trenchless, one-piece, Main/Lateral CIPP Solution that utilizes Gasket Sealing Technology and all of the other unique features as found in a standard T-Liner® including vacuum impregnation, inversion installation, full-circle main liner construction, tapered ends for a smooth transition, lateral identification, and a long-term sealed impervious coating, all without the need for an outside cleanout.

Compressible Material on Mainline and Lateral Tubes
A strip of Compressible Material which compresses to nearly a zero thickness is used to form an engineered taper which provides a smooth transition for maximum flow rate.
Hydrophilic O-Rings on Mainline Tube
Bonding a CIPP connection liner is problematic and scientifically unsubstantiated due to Fats, Oils and Grease (F.O.G.) which are present in a sewer system; and olefin based coatings (PE or PP), materials well known to resist bonding or properties for adhesion. The solution is two hydrophilic O-rings positioned on each side of the lateral connection. These swelling gaskets are embedded between the mainline tube and the main host pipe; and expand 3 to 5 times their original size in the presence of water. The full-circle compression gaskets provide for a verifiable non-leaking connection and are compatible with all types of pipe and pipe lining materials. This is technology tried and true as compression gasket sealing has been used extensively in bell and spigot pipe joining applications for many years.
Hydrophilic O-Rings on Lateral Tube
A hydrophilic O-ring is incorporated at the upper most end of the lateral liner tube. This swelling gasket is embedded between the lateral liner tube and the lateral host pipe. This hydrophilic O-ring expands 3 to 5 times its original size in the presence of water. The full-circle compression gasket provides for a verifiable non-leaking connection and is compatible with all types of pipe and pipe lining materials. Compression gaskets have been used extensively in bell and spigot pipe joining applications for many years.
Full Circle Design
Just like direct bury pipes, CIPP linings are designed from calculations based on physical properties of the CIPP, the depth of pipe being renewed, pipe diameter and soil/hydrostatic loading. The key element in the design calculation is the CIPP being formed as a "tube or cylinder". LMK's SHORTY® incorporates a structural full-circle main liner tube having proper wall thickness for each pipe diameter.
Continuous Lateral Tube
The lateral portion of a SHORTY® consists of a one- piece continuous lining that extends up the lateral pipe 3-feet. The robotic positioning and installation in performed without the need for a cleanout. The entire Main & Lateral lining is resin saturated all at the same time and cured all at the same time thus producing a one-piece homogenous cured-in-place pipe.
Lateral Indicia
The mainline portion of a SHORTY® is permanently marked with a Lateral Identification that includes the physical building address. Other valuable information such as date of manufacture, the installation contractor and the manufacturing code which details pertinent control information about the materials, resin and catalyst used to build this cured-in-place pipe. Through video inspection, owners may track valuable information from the indicia as needed such as which building is feeding a specific connection as well as quality control of the installed liner.
