Abstract
A method of sealing a leaking crack in a structure involves drilling a delivery channel into the structure adjacent the crack and in towards the crack to join the crack. A delivery nozzle is inserted into the delivery channel to inject a sealant comprising latex and water under pressure into the crack. The sealant may be injected until the sealant forms a seepage on an exterior surface of the crack which is sprayed with a reactive agent to cure the sealant to form a skin. Thereafter further sealant may be injected via the delivery channel after the skin is formed to enhance the ingress of sealant within the crack.

A method of sealing a leaking crack in a structure, the method comprising:
- drilling a delivery channel into the structure adjacent the crack and in towards the crack to join the crack,
- inserting a delivery nozzle into the delivery channel and injecting a sealant via the delivery nozzle comprising latex and water under pressure into the crack,
- injecting the sealant until the sealant forms a seepage on an exterior surface of the crack,
- spraying the seepage with a reactive agent to cure the sealant across the surface of the crack to form a skin across the exterior surface of the crack;
- and
- injecting further sealant via the delivery channel after the skin is formed.
