Systems and methods for depositing compounds in a structure

A method for depositing a compound into a void of a damaged area of a structure, the method comprising:

• positioning a vacuum canister with respect to the void such that a canister outlet of the vacuum canister surrounds an opening to the void, the canister outlet being configured to allow the compound to flow into the void from a dispenser configured to hold the compound to be dispensed into the void, and wherein at least a portion of the dispenser is positioned within the vacuum canister;
• forming an at least substantially air-impermeable seal between the canister outlet and the structure;
• drawing air out of the vacuum canister and the void to maintain a target reduced air pressure within the vacuum canister, using a vacuum system operably coupled to the vacuum canister via a vacuum port;
• and
• moving a valve from a first position, in which the valve is operable to retain the compound in the dispenser, to a second position, in which the compound flows from the dispenser, through at least a portion of the vacuum canister, and into the void, wherein the moving the valve to the second position is performed during a period of time during which the target reduced air pressure is maintained, wherein the period of time is sufficient to allow the compound to flow into the void.

A method for depositing a compound into a void of a damaged area of a structure, the method comprising:

• at least partially filling a dispenser with the compound, via a dispenser inlet of the dispenser, wherein the dispenser is configured to hold the compound to be dispensed into the void;
• positioning a vacuum canister with respect to the void such that a canister outlet of the vacuum canister surrounds an opening to the void, the canister outlet being configured to allow the compound to flow into the void from a dispenser outlet of the dispenser, wherein the dispenser outlet is configured to channel the compound to the vacuum canister, wherein the at least partially filling the dispenser is performed when the dispenser is spaced apart from the vacuum canister, and wherein the dispenser outlet is the same as the dispenser inlet;
• forming an at least substantially air-impermeable seal between the canister outlet and the structure;
• drawing air out of the vacuum canister and the void to maintain a target reduced air pressure within the vacuum canister, using a vacuum system operably coupled to the vacuum canister via a vacuum port;
• and
• moving a valve from a first position, in which the valve is operable to retain the compound in the dispenser, to a second position, in which the compound flows from the dispenser, through at least a portion of the vacuum canister, and into the void, wherein the moving the valve to the second position is performed during a period of time during which the target reduced air pressure is maintained, wherein the period of time is sufficient to allow the compound to flow into the void.
