KURADRIP™ is a drainage-promoting water conduit pipe that is embedded into structures such as bridges, tunnels and railroad tracks to prevent deterioration due to water infiltration (rainwater). It helps to extend service life by preventing the infiltration of fine sand and soil, mortar and concrete, and using the capillary phenomenon to drain only infiltration water such as rainwater. It is attracting interest as a waterproofing measure in bridges and tunnels, which have been a focus of concern because of sudden intense downpours in recent years, and as an effective means of draining retained water and excess water. It is currently used for the Metropolitan Inter-City Expressway and the Tokyo Gaikan Expressway.
In addition, KURADRIP™ is used in tunnels to improve the quality of concrete by removing excess water from concrete after pouring.
