Natural cork contains suberin, lignin, and tannins. In the presence of standing water (pH 6–8), cork is stable for >72 hours. However, if residual chemical cleaners (pH > 12) are present, saponification of suberin occurs, leading to surface delamination and loss of sealing ability. Therefore, cork usage is recommended chemical treatment.

Consider a vertical drain pipe of diameter ( D_p ) and a cork of undeformed diameter ( D_c > D_p ). After insertion, the cork compresses, generating a radial stress ( \sigma_r ). When water is added above the cork, the pressure head ( \Delta P = \rho g h ) (where ( h ) is water column height, typically 0.2–0.5 m) creates an axial force:
