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.
Claims17
A method of sealing a leaking crack in a structure, comprising the steps of:
- 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, the sealant 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 which is continuous and synonymous with the sealant within the crack;
- injecting further sealant via the delivery channel after the skin is formed;
- and
- allowing the sealant to cure into a flexible durable seal for the crack.
