CULVERT REHABILITATION

From our client friendly Project Managers and highly experienced Foremen to our wealth of innovative technology, Triangle Contracting is well equipped to fulfill and satisfy all aspects of your excavating needs.

Our experienced, dependable staff and efficient management techniques make the installation of sewer, water, storm drain, and HDPE lining systems possible no matter how tough the environment.

Uniquely, Triangle employs both a pioneer and leader in the field of digital terrain models. Implementing this innovative technological asset can save clients an extraordinary amount of time and money.

Triangle employs culvert shotcrete and centrifugal spin cast rehabilitation for the repair of culvert systems rather than the traditional, disruptive replacement of them. This trenchless technique allows for reduced cost and reduced impact culvert repairs.

STORMWATER MANAGEMENT

Our plentitude of experience in completion of all aspects of stormwater ponds, bioretention, retrofits, and restorations meeting Maryland State standards, makes stormwater management Triangle’s area of expertise.

PIPE BURSTING

Triangle employs an efficient, trench-less method of replacing pipelines. This technology is used to replace or increase the size of an existing, failed sewer line without the need for a traditional construction trench. 

MANHOLE REHABILITATION

We are equipped to employ manhole rehabilitation. This process is used to protect and reinforce existing sewage manholes rather than replacing them. It is employed to restore structural integrity and prevent future breakdown of the manhole.
