How Sewer Line Repairs Are Done Under Concrete Slabs

If the pipes underneath your house are leaking, chances are that they are worn out. Wear on your water pipes may not cause damage immediately, but the water leaks may generate a massive spike in your water bill. You should avoid replacing or repairing sewer lines under the pavement by yourself. Here is a step-by-step guide on how contractors conduct sewer line repairs.

However, a reliable sewer line improving company will diagnose the problem with your sewer line using CCTV. This live inspection will determine whether the sewer lines need to be replaced or repaired through relining. This process uses composite resins and liners for drinking water, stormwater, and chemical pipes. Ropes are used to pull the liners into place. The technician then mixes the two-part epoxy resins and injects them into the liners. The liners are then activated under pressure to cure and harden the liners. Over time, the liners harden like a rock and form a new pipe inside the old one. The new pipe is guaranteed to last up to five decades.
