Mar-Con Products, Inc. Mar-Con Products, Inc. supplies precast concrete sewer and storm drain manholes throughout San Diego

From a modest beginning in 1975 with three employees, including founder Mark Santar, and one crane truck, Mar-Con Products has grown to a company noted for leadership and specialization in two interrelated segments of San Diego County’s construction industry: manufacturer of precast concrete manholes and suppliers of ready-mixed concrete. Today’s Mar-Con fleet includes three crane trucks, and a mo

dern concrete batching plant. As an additional customer benefit, and on request, Mar-Con offers complete manhole installation services through R&C Structures, Inc., a Class A licensed contractor. Servicing San Diego County contractors and municipal agencies, Mar-Con’s entire scope of operations, from production of precast concrete sewer manholes--including rectangular covers—to its well stocked and readily available supply of cast iron frame and covers, storm drain, and curbing materials, including carefully controlled concrete batching and dispatching operation, are all focused in Mar-Con’s 2 ½ acre San Marcos, CA headquarters. Today Mar-Con’s operation has helped earn Mar-Con the title as a competent and totally professional and reliable One Stop Facility for manholes and sewer and Storm drain structures and related supplies.
