Methods
Modern‐day trenchless contractors and engineers have a variety of no‐dig methods available in their proverbial toolbox. Having many options is advantageous; however, selecting the right approach can sometimes seem challenging.
Trenchless construction is defined as “a family of methods, materials, and equipment capable of being used for the installation of new or replacement or rehabilitation of existing underground infrastructure with minimal disruption to surface traffic, business, and other activities.”
For nearly 50 years, Akkerman has been innovating solutions to meet the trenchless industry’s demands and offer contractors equipment to perform some of the most popular and efficient trenchless methods available.
