LMK Technologies Continues to Innovate in the Trenchless
Rehabilitation of Main-to-Lateral Connections

Located in Ottawa, Illinois, LMK Technologies has been a leader in trenchless Cured-In-Place-Pipe (CIPP) lining since 1993. LMK is recognized by
many municipalities and engineering firms as the innovative leader for the
trenchless renewal of sewer laterals, manholes and mainlines. LMK has
over 100 issued patents and many pending. Overall, LMK has continuously innovated solutions towards trenchless rehabilitation of main-to-lateral
connections year-in-and-year-out while also striving to find new ways to
change the industry.
LMK's Sectional Connection Liner process renews
pipes from 8 to 12 inches
in diameter and in continuous lengths up to 6 ft. while
simultaneously renewing
the connection and the lateral service pipe for up to 8
ft. The liner can be inverted
anywhere in the pipe with no
trimming or cutting. The result is a structural, root proof, watertight liner.
Gasket sealing technology is used at the terminating points of the liner by
embedding LMK patented Insignia™ Hydrophilic O-Rings between the liner
and the host pipe to ensure a watertight seal.
LMK's Man Entry Lapel Liner was announced in 2015 as a large diameter liner using patent pending technology that allows for a watertight connection to be made to either the CIPP lining or to the original host pipe. This
is a mechanically anchored liner that also includes the use of molded gaskets
made of hydrophilic rubber and a metal brim flange. The liner system consists of a fabric tube of the desired length with a factory attached brim and a
thermo-set CIPP resin system. The mainline brim and lateral tubes are vacuum impregnated with the resin, the hydrophilic gaskets are installed, and
then the liner is mechanically placed inside the pipes via man entry into the
mainline. The connection stays in place with the stainless steel compression
ring that is fastened to the main pipe to create a one-piece lateral lining and
sealed connection.
LMK's T-Liner® is a one-piece
main-to-lateral connection system
with Insignia™ hydrophilic gasket
sealing technology fully compliant with ASTM F2561-17. The
full circle CIPP mainline portion
creates a 50 year structural repair
while the lateral portion simultaneously renews the lateral up to
150 feet. T-Liner 3.0 uses Insignia
O-ring gaskets at the lateral termination and a connection hat,
both made of hydrophilic rubber,
at the main-to-lateral connection,
creating a long-term watertight seal to match the structural life. This system can be installed with either polyester or epoxy resin in lined or unlined
mainlines.
For shorter lateral shots, LMK's T-Liner Shorty and Stubby are available. Shorty is ASTM F2561 compliant and extends up the lateral a length
of 10 feet. Stubby renews the connection and 6 inches of the lateral. Both
of these shorter T-Liner systems utilize the Insignia junction hat at the connection, ensuring a watertight renewed system.

Installed from the mainline are T-Liner, Shorty and Stubby and are positioned at the lateral using the latest in positioning technology including
robotics and cameras. The inversion and steam or ambient cure process ensures a consistent quality installed liner that is compliant with ASTM F2561
and F1216.
All of LMK main-to-lateral connections systems are installed by licensed
trained independent contractors who make a significant investment to
ensure quality installations. LMK's installers are required to complete an extensive and rigorous training course at LMK's state of the art facility as well
as on-the-field training.
For manhole to manhole CIPP rehabilitation, the ASTM F3240-17 compliant LMK Insignia™ End Seal sleeve is available in diameters from 6
inches and up. When used in conjunction with mainline CIPP lining, the Insignia gasket forms a watertight seal in the annular space between the liner
and the host pipe after 24 to 36 hours of being exposed to water. An annular space always exists between the host pipe and the liner because CIPP
resins do not bond to the host pipe. Without the compression gasket, water
will track behind the liner and re-enter the collection system. The Insignia
End Seal is available to all contractors installing manhole to manhole CIPP.
For lining lateral pipes
only, LMK's Performance
Liner System is installed
from one access point using
custom fabricated, highly
engineered equipment.
LMK's lateral liner repairs
and rehabilitates broken and
leaking pipes with diameters
of 3 to 8 inches. No digging
is required to line 4 inch pipes up to 130 feet or 6 inch pipes up to 100
feet. Performance Liner Lining System is NSF/ANSI 14 certified and meets
ASTM F1216.
If an outside cleanout is not available, LMK's VAC-A-TEE® can be easily
installed by vacuum or hydro excavation of a small diameter hole. Outside
cleanouts ensure proper resin wetout, allow for steam venting and minimize
disruption to the homeowner. VAC-A-TEE meets the ASTM F3097-15 Standard, a practice for installation of an outside sewer service cleanout through
a minimally invasive small bore created by a vacuum excavator.
LMK offers truly engineered solutions that are backed by a 10 year CIPP
limited warranty, world class research and development, technical sales and
service teams.
LMK is a major supporter of the underground construction and trenchless technology industry and participates in many major educational and
business events throughout the United States and Canada. A member of
NASSCO, NASTT, WEF and numerous other organizations, LMK gladly
opens its Interactive Technical Education Center (ITEC) for training sessions and demonstrations.
