Exact date: March 3. Ted Purington, Sr. and wife, Judy, borrowed $2,000 with 3 co-signors to form Maine Drilling & Blasting. From the kitchen, the business grew into the barn, then into a secondary tin building at the family homestead in Gardiner, Maine.

While interstate highway and municipal sewer projects provided numerous out-of-state opportunities, the company's rapid expansion sorely tested the company's resources. Three of four sons, Ted, Jr., Jim and Tom, became involved with the company in different capacities.

MD&B expanded its territory to all the Northeastern states, as far south as Maryland and Pennsylvania.

MD&B had established seven operating divisions with a peak work force of more than 150 employees - up from 31 in 1982. The company had also moved strongly into the quarry market.

By the end of 1991 the company had consolidated operating divisions from 7 to 4, reducing fixed costs by more than 40%. Emerging stronger, MD&B was more dedicated than ever to local service.

MD&B strengthened its commitment to the New England market with several other key acquisitions of strategic competitors, their employees and local facilities.

MD&B became the first contractor in the country to construct and operate its own bulk explosives blending and loading plant.

Just shy of MD&B's 40-year mark, the company hit the milestone of performing one million controlled blasts for various projects, including highways, site development, quarries, houses lots, utilities and marine work.

MD&B successfully acquired the company's largest northeast competitor located in MA, and opened new strategic explosive storage facilities in CT and NY. MD&B also began increasing its presence in the hydro, pipeline, wind and other energy market

MD&B engineered a very large bulk emulsion transport hauled by a dozer capable of holding and direct-pumping 10,000 lbs of product. This Bulk Skid^TM enables bulk to be transported on and off shots in extremely isolated terrain, increasing efficiencies on projects such as pipelines and wind farms.

As of December 31, 2010, MD&B employees owned 30.5% of the Company.

Over these past five years, MD&B has experienced accelerated traction in several areas, from service expansion of its Mid-Atlantic region, to growth of its Common Culture initiative, and advancement of its Leadership Development Program, transitioning into the next generation of leaders.

As of March 15, 2017, the Company’s ESOP Trust completed a transaction that purchased additional shares progressing employee ownership from 31% to 51%.

The use of UAV’s became paramount to MD&B’s imaging models. Now, drones are part of construction and quarry pre-blast providing highly detailed 2-D and 3-D virtual models of blasting sites taking MD&B to higher levels of efficiency and safety.

Over the past 20 years, MD&B has become recognized as a leader in geotechnical drilling and foundation services. In 2019 the Company formally established a Foundation Services Division dedicated to this work throughout all service areas to meet the high demand for rock anchors, guy anchors, micropiles, tiebacks and tie downs for a variety of construction needs.

MD&B continues its tradition of local service with offices in Maine, New Hampshire, Vermont, New York, Massachusetts, Pennsylvania, Connecticut and Tennessee.
