Manholes, by the millions, are a major source of I & I. Older brick structures as well as newer pre-cast manholes can be repair using a variety of products and techniques. At Applied Science, we believe that despite what many manufacturures claim, there is no one “best” product for the repair of manholes.
With installations in as many different environments as there are environments, product/method selection must take many factors into consideration. Regardless of the method indicated, maximum performance of any product depends on one thing…. the skill and attention to detail with which it is applied. Experience, training and supervision are essential. Chemical Grouting, Cementious and epoxy liners can provide excellent return on investment.
