Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When purchasing waterproofing and leak sealing, it is usually necessary to focus on key technical parameters such as anti-seepage pressure and bonding strength of the product to ensure that it can meet the long-term waterproofing needs of different scenarios such as basements and tunnels.
  • When selecting suppliers, priority can be given to product matching, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information to screen out partners that meet engineering requirements.
  • For local leakage repair scenarios such as roofs and bathrooms, it is recommended to choose waterproof sealing materials with good flexibility and moderate curing time to meet the requirements of base deformation and rapid construction.
  • When evaluating waterproof and leak sealing products, the reliability of the supplier's technical solution can be comprehensively judged based on their actual application cases in municipal engineering or building repair fields.
