| PE sheet waterproof lining using joint fixing member |

Sanitary safety Patent
standards trademark
• Waterproof lining method for realizing perfect waterproofing and improving durability, constructibility, economic feasibility, etc.
by fixing using double panel members at the joint of PE sheet
• By securing stability between PE sheet and concrete structure by using double panel fixing members, existing problems are
improved, such as better constructibility and durability than non-adhesive construction method using fixtures, and reduction of
initial cost compared to adhesive PE sheet waterproofing method.

Concrete Concrete

PE Sheet

PE sheet lining

Features and Advantages
① Strengthen leak prevention by expanding and reinforcing water tightness
② Strengthen durability (perfectly solved the peeling / falling phenomenon of PE sheet)
③ Improved durability compared to fixture construction method
④ Reduced initial cost and improved constructibility compared to adhesive construction method
⑤ Reduced LCC (life cycle cost) by improving durability
- Reconstruction cost (at least once)
- Maintenance and management cost
⑥ Secured hygiene by using joint fixing members that are harmless to the human body
- Secure reliability by using materials that have acquired international certifications NSF61 and WRAS
