Key Features:

LMK’s ASTM F3033 compliant, universal, stretchable, one-size-fits-most Cured-in-Place Manhole Shorty Liner System is engineered to produce a cured in place seal that resists freeze/thaw conditions. Since the Cured-in-Place Manhole Shorty Liner System utilizes a stretchable liner, site preparation and installation can occur in the same day eliminating the lead-time for ordering. The Cured-in-Place Manhole Shorty Liner System can be installed as a chimney seal or full-depth manhole lining. Once the liner has been vacuum impregnated and manually inverted into the manhole, the liner will cure ambiently under pressure in one to two hours depending on depth. Gasket sealing options are available.

Standard Practice for Installation of a Single-Sized, Cured-In-Place Liner Utilizing an Inflatable Bladder for Resurfacing Manhole Walls of Various Shapes and Sizes

Significance and Use

This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of manholes ranging from 24 in. (0.61 m) and larger in diameter without excavation through the use of a resin-impregnated tube installed within an existing manhole. As for any practice, modifications may be required for specific job conditions.

The CIPMH liner is suitable for circular and noncircular manholes with varying diameters along the depth of the manhole.

The design engineer shall determine the CIPMH liner requirement to withstand external loads.


  1. This practice covers requirements for the cured in place rehabilitation of manholes without excavation, utilizing an inflatable bladder, and not limited to sanitary sewer manholes.
  2. The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
  3. There is no similar or equivalent ISO standard.
  4. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.
