Ultra Manhole 3

Single Piece Manhole :
In most of the projects the invert depth of manhole is normally below 3.0 m, for such applications the use of three piece manhole may not be cost effective. Considering this fact our design team have come out with the light weight yet strong manhole in single piece design. Like our existing 3 piece design manholes, this uniquely designed cost effective product is strong enough to withstand all sorts of loads. This new design offers following additional benefits.
Single piece cost effective design – This uniquely designed product is made available in single piece and hence the need for rubber ring used for connections of base, shaft and cone are eliminated besides substantial saving in total product weight.
Easy and fast installation – Being in single piece and lighter in weight it is very easier for installation. This single piece manhole is made available in different depths from 1.2 to 3.0 m invert depths with a difference of 0.3 m and hence it can be selected as per the site requirement.
Light weight yet strong and sturdy – In spite of light in weight, this uniquely designed product is strong and sturdy to handle all sorts of soil and traffic loads that will encounter during and after installation.
