We’ll start by descaling the pipe and removing the buildup to ensure the lining fits through. Then we’ll use a CCTV camera to inspect and measure the pipe so the lining can be cut to size. We’ll cover the sleeve in resin and push the bladder (or the “balloon”) through the pipeliner. After that, we insert the liner in the pipe and blow out air to expand it. We’ll wait for the resin to harden and pull out the bladder.
