Trenching is the most common way to do a sewer repair. It requires the dirt to be dug up to expose the sewer line for repair. Trenching can be performed to expose a small area for a spot repair of a sewer line or it can be digging up an entire length of a sewer line. Trenching is generally done using an excavator, mini excavator or backhoe. In some cases, when it is not possible to get equipment in to the job site, a hand dig is required. Safety is always our main concern when trenching. Our crew is trained with the strictest safety standards. We use a system called trench shoring, where two pieces of metal are assembled to line the trench on either side and keep the dirt from caving in. Our crew is trained to operate heavy equipment with a high degree of accuracy, which is important to successfully avoid underground utilities and other obstacles such as power lines and homes.
Sewer Lines Only is careful to protect the integrity of your landscaping. Having a procedure to handle the dirt that comes out of a trench is important. Some of the dirt will be excess, which we load into a dump truck and dispose of off-site. The reason not all of the dirt will go back into the trench is because a new sewer line will be bedded with ¾ inch crushed granite or squeegee. This bedding material prevents the new sewer line from shifting causing low spots. We will lay down ply wood on grass to preserve the landscaping.
