A foam generation and distribution gun , comprising: a. an upstream end and a downstream end ; b. a first elongated chamber of a first diameter and in which a plurality of bubble forming media are contained and that extends between a first end portion positioned adjacent to said upstream end, and an opposite second end portion ; wherein said bubble forming media comprises beads composed of glass ; c. first and second conduits for carrying bubble fluid and compressed air, respectively, to said first end portion , wherein a mixture of bubble fluid and compressed air is generated and forcibly passed through said first elongated chamber at a first pressure, whereby upon exiting said first chamber a foam fluid is formed from said compressed air and bubble fluid; d. a second chamber extending from said first elongated chamber and in which a first foam fluid reforming structure is contained, whereby said foam fluid is reformed as it exits said second chamber; wherein said first foam fluid reforming structure comprises first and second mesh screens positioned in spaced parallel relation to one another; e. a third chamber extending outwardly from said second elongated chamber and in which a second foam fluid reforming structure is contained and through which said foam fluid passes, wherein said foam fluid is at a second pressure lower than said first pressure upon entering said third chamber and at a third pressure equal to said second pressure upon exiting said third chamber; f. a foam distribution conduit positioned downstream from said third chamber; and g. a third conduit for carrying cement to said foam distribution conduit , wherein said cement is combined with said foam fluid prior to passing through said foam distribution conduit, wherein said cement and foam fluid combination are mixed together at a fourth pressure lower than said second and third pressures. a. an upstream end and a downstream end ; b. a first elongated chamber of a first diameter and in which a plurality of bubble forming media are contained and that extends between a first end portion positioned adjacent to said upstream end, and an opposite second end portion ; wherein said bubble forming media comprises beads composed of glass ; c. first and second conduits for carrying bubble fluid and compressed air, respectively, to said first end portion , wherein a mixture of bubble fluid and compressed air is generated and forcibly passed through said first elongated chamber at a first pressure, whereby upon exiting said first chamber a foam fluid is formed from said compressed air and bubble fluid; d. a second chamber extending from said first elongated chamber and in which a first foam fluid reforming structure is contained, whereby said foam fluid is reformed as it exits said second chamber; wherein said first foam fluid reforming structure comprises first and second mesh screens positioned in spaced parallel relation to one another; e. a third chamber extending outwardly from said second elongated chamber and in which a second foam fluid reforming structure is contained and through which said foam fluid passes, wherein said foam fluid is at a second pressure lower than said first pressure upon entering said third chamber and at a third pressure equal to said second pressure upon exiting said third chamber; f. a foam distribution conduit positioned downstream from said third chamber; and g. a third conduit for carrying cement to said foam distribution conduit , wherein said cement is combined with said foam fluid prior to passing through said foam distribution conduit, wherein said cement and foam fluid combination are mixed together at a fourth pressure lower than said second and third pressures. <EOS>
