A repair formed inside a suitable pipe
A flexible liner is prepared for the measured section, inserted through an access point and formed against the inside of the host pipe. It then cures to create a continuous inner layer. The actual material, insertion and curing method depend on the pipe, defect, access and system selected for the job.
Locate and assess the affected run.
Clean suitable pipework and measure the section.
Position and form the liner inside the pipe.
Allow it to cure, then inspect the repaired run.
When lining may not be the answer
A collapsed section, unsuitable pipe condition, poor access or another site constraint may point to a different repair. Drain Star does not claim that lining avoids excavation in every case.
