South Rock Ltd. was incorporated in Medicine Hat in the spring of 1973 as a municipal asphalt paving company. In its beginning, South Rock was a division of Everall Construction but was incorporated as a separate entity in 1975.

In 1979 South Rock expanded its operations by purchasing a complete mobile highway paving spread from Everall Construction, followed by the purchase of a second highway plant in 1984 and later the acquisition of the City of Medicine Hat Municipal Asphalt Plant in 1996. In 1997, the original asphalt plant was moved to its current permanent location, near Beiseker, AB. Both Municipal plants have been continually upgraded and expanded to today's models, which are twin 150TPH state of the art drum-mix plants. In 1997 and 1999 SRL replaced the original highway plants with CMI Corporation PVM400 and PVM500 mobile drum mix plants. The four plants are maintained by a factory trained supervisor on our worksites and in our Redcliff shop during the off-season. Our four asphalt plants have a combined production capacity in excess of 1.2 million tonnes of ACP per season.

In 1996 South Rock Ltd. became the first contractor in Alberta to set up its own Material testing Laboratory in Okotoks, AB. The purpose of the lab was to provide superior asphalt and aggregate testing and asphalt mix designs for our various projects. In 2002, the lab was relocated to our Calgary office where it remains today.

In recent years, South Rock has expanded into the business of aggregate production, operating two mobile crushers capable of supplying all of our own aggregate for our mobile paving projects.
