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.

Abstract: A transport facilitation system can receive current location data from driver devices of drivers operating throughout a given region. The system can further receive a pick-up request from a user device of a requesting user within the given region, the pick-up request including pick-up location data. The system can determine a plurality of candidate drivers to service the pick-up request based, at least in part, on the pick-up location data and current location data of the candidate drivers. The system can predict a future location for each of the candidate drivers and select a first driver from the candidate drivers to service the pick-up request based on the predicted future locations. The system may then transmit a transport invitation to the first driver to service the pick-up request.
