Drainage plays a critical role in the design and construction of below grade applications. Without proper drainage, groundwater seepage may cause hydrostatic pressure and leakage, resulting in structural damage. MiraDRAIN's multi-directional flow design allows a continuous path for water discharge, eliminating the potential for hydrostatic pressure build up. It allows water to pass freely into the drainage core, where it is gravity fed into the CCW QuickDRAIN drainage collection system.

Composite Drainage Board to replace the drainage layer pebbles treatment not only save time,effort and energy, saving investment, but also reduce the load of the building. Good Drainage system for normal use and life cycle of civil construction and the building has an important role.
