This is the Engineer's Corner section,
specifically developed to inform engineers and specifiers with
updates and technical information. These technical updates generally
provide assistance in accessing technical and test information
as well as service education and documentation for the specification
of our products.
The following links will outline our manhole
leak rehab program, methods for installing and specifying chemical
grout, case studies and products. We also have measurement
tools and units conversion help on our website. Some of the
links below will show you excellent illustrations and diagrams
to follow, as well as step-by-step procedures and results.
Please note that you will need Adobe Reader

COMMITTEE WORK UPDATE
The new ASTM standard for the chemical grouting
of manholes has been passed and will be made available at
the www.astm.org
website. This is standard designation:
F 2414-04 Standard Practice for Sealing Sewer
Manholes Using Chemical Grouting.
For other ASTM Standards Committee F36 on Technology
and Underground Utilities
has been developing feel free to check out the committee page
and articles at www.astm.org
by clicking on "Technical Committees" in
the menu and entering "F36" as the designation for search.
