A good excavation contractor is necessary for any job to be done properly. Land clearing, grading, demolition work and septic systems are all projects that should only be handled by the right people for the job and never by a homeowner on his or her own. At DMT Enterprises, we are experts at our craft and our 25 plus years of business give us the experience necessary to get the job done right.

Land Clearing

Having your land properly cleared is not as easy as it may seem. When clearing land, trees, stumps, brush and stones must be removed to leave the land clear and workable. Without the proper removal, a contractor trying to build a foundation, for example, may run into problems if the land was not properly cleared before he began his work. It can also cause problems with gas or cable lines if grounds are not cleared correctly. At DMT Enterprises, Inc. we take every precaution to ensure that your land is clear and free of anything that might get in the way of whatever you would like to do with your land.


We are often called by homeowners who have had other companies complete their jobs only to find that they now have puddles or pools of water that shows that their land was not properly graded. Properly graded land does not just create a flat piece of property for the homeowner. Land that is graded the right way is graded for proper water runoff. If we are grading land for a driveway, for example, we have to make sure that the water that lands on the land that we are trying to grade will eventually run to the correct receptacle, whether it be a town sewer or French drain we make sure that the land is graded properly to avoid any future problems that the homeowner might face. If you have a wet basement or crawlspace when it rains or if you have pooling water around your foundation, then your land probably is not properly graded. We have the experience necessary to determine the problem and fix it as quickly as possible.


Demolition work should always be done by a professional. Demolition work does not just involve knocking existing structures down. We do our demolition work in a proper and orderly manner, making sure that there is no damage to adjacent structures and taking precautions when it comes to power lines, etc. It can also be very dangerous to the people around the structure if the demolition work is not done by a professional. We also remove all of the debris from the premises, leaving the homeowner or building owner free to do how he or she wants with the cleared area.

Septic Systems

A septic system is basically an efficient wastewater management system on your own property. It works by collecting the waste from your home and draining it into a drain field or leach field where it is distributed naturally back into the earth. We install septic systems and drain fields that will correctly collect and distribute any waste that comes from your home or business. Our installations are done the right way and last our clients for years to come.
