It is a method that allows for water collection from a wide area using a collection pipe.
The weep hole function regeneration drain method involves the installation of weep holes into existing structures such as road retaining walls and waterways through post-construction. Due to its three-dimensional structure, it can form drains that are less prone to clogging. Since the drain pipe (saya pipe) can be removed, it is easy to clean or replace the filter layer in case of clogging. Therefore, maintenance such as restoring back drainage function becomes easier, allowing for the function to be maintained permanently. 【Features】 ○ Can collect water from a wide area through the collection pipe ○ Removable and can be cleaned internally ○ Small drilling diameter allows installation without cutting the rebar in the structure ○ Large volume of the collection pipe makes it less prone to clogging ○ Easy to install, even possible to construct when there is outflowing water For more details, please contact us or download the catalog.

basic information
【Construction Method】 - After drilling holes in existing structures using core extraction, a drain pipe with a special filter (saya pipe) is driven in, followed by the installation of weep holes. - NETIS registered method Registration Number: HK-110050A 【Effects】 - Retaining walls that have become clogged due to aging → Can restore the function of drainage holes. - Water channels that have become clogged due to aging → Can restore the function of weep holes. - Water channels and retaining walls that require improved drainage functionality due to an unexpected rise in groundwater levels → Drainage capacity is enhanced through post-construction. - New installations in areas considered prone to clogging due to soil conditions → Lifecycle costs can be reduced. - Areas at risk of frost heave in cold regions → Can prevent frost heave. ● For more details, please contact us or download the catalog.
