Who We Are

With a growing number of roads and bridges in disrepair, and a limited amount of resources available for determining viable solutions, there was a need for an agent to facilitate the identification, selection and construction of existing and new processes for addressing these needs.

S Drain Engineering of IL, LLC was founded with the idea of aiding agencies and contractors in the understanding, design, construction and preservation of roadways and the associated facilities.

Through site evaluation, process review, specification creation and modification and construction site support, S Drain Engineering is a consulting firm that provides the necessary assistance to build and maintain strong and sustainable roads, bridges and highways.
