1. A modular enclosure system for repair of one or more leaks in a pipe, comprising:
a first enclosure portion and a second enclosure portion configured to be disposed in a mated configuration to create a first enclosure around the pipe, the first enclosure including:
a first void section configured to enclose a first pipe section of the pipe;
a first end section with a first opening configured to accommodate the enclosed pipe and a second end section with a second opening configured to accommodate the pipe, wherein the first end section includes a first bore groove and the second end section includes a second bore groove;
a first hub connected to the first end section and a second hub connected to the second end section, wherein the first hub has a first hub end face and the second hub has a second hub end face,
a first sealant groove extending along the void section and a second sealant groove extending along the void section, the first sealant groove and the second sealant groove configured to extend along opposite sides of the enclosed pipe and wherein,
the first sealant groove and the second sealant groove each extends from the first hub end face to the second hub end face; and
the first bore groove and the second bore groove are each connected to the first sealant groove and the second sealant groove; and
a first sealant control system having a plurality of blocking members and configured to selectively block sealant injected in the first enclosure to the first sealant groove and the second sealant groove, each of the plurality of blocking members in the first sealant control system positionable between a blocking position configured to block sealant flow in at least one of the first sealant groove and the second sealant groove and a non-blocking position configured to allow sealant flow in at least one of the first sealant groove and the second sealant groove, wherein
the plurality of blocking members includes:
a first blocking member and a second blocking member, the first blocking member positionable in the blocking position to block sealant flow in the first sealant groove at a first blocking location and the second blocking member positionable in the blocking position to block sealant flow in the first sealant groove at a second blocking location; and
a third blocking member and a fourth blocking member, the third blocking member positionable in the blocking position to block sealant flow in the second sealant groove at a third blocking location and the fourth blocking member positionable in the blocking position to block sealant flow in the second sealant groove at a fourth blocking location; and
the first blocking member and the third blocking member in the blocking position are configured to block sealant flow between the first bore groove and the first hub end face, and wherein the second blocking member and the fourth blocking member in the blocking position are configured to block sealant flow between the second bore groove and the second hub end face.
