A method for sealing at least one leak in at least one of a mains pipe and at least one lateral pipe, the method comprising:
- passing at least one pig train comprising at least one gel pig and at least one sealant composition comprising at least one of wound fibers and yarns, under pressure along the mains pipe and said at least one lateral pipe such that a portion of said pig train enters said at least one leakage site to seal said at least one leak.
A method for sealing a leak at a leakage site in a mains pipe, the method comprising:
- a) passing at least one of a pig train and a sealant composition under pressure along a lateral pipeline such that a portion of said at least one of a pig train and said sealant composition enters said mains pipe from said lateral pipeline;
- and
- b) allowing said portion to reach said leak site and to seal said leak.
A system for sealing a leak in a lateral pipe from a main pipeline, the system comprising:
- a. at least one sealant composition comprising at least one of wound fibers and yarns;
- b. at least one gel pig;
- and
- c. a pressure control system for controlling at least one of a pressure in said main pipeline and a pressure in said lateral pipe.
