Waterproof sleeve for underground and outer wall use "Pipe-In-Sleeve"

At the underground wall section (underground beam sleeve), a "waterproof treatment" is applied in advance at the factory to the outer space (gap) between the PVC sleeve and the FEP, and it is prefabricated for the site. No cumbersome work is required on-site; after the PIS installation, basically only joint connections are needed. Ensuring stable waterproofing! Improving work efficiency and achieving labor-saving, also promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction.
