⭐ **WATERSTOP for Swimming Pool Construction
Selection Guide + Specifications
(Standardized by Pool Size & Structure WINWINPOOL Edition)**

Waterstop is a critical rubber component used to prevent water leakage through concrete joints in swimming pool structures.
Common application points include:

Wallfloor joints
Cold/construction joints
Expansion joints in deep pools or hotel pools
Selecting the correct type, width, rib count, and thickness is essential for long-term leak prevention.

Winwinpool waterstops are manufactured according to:
TIS 1135-2544 and AASHTO standards,
with material properties suitable for structural engineering use:

Hardness: 69 Shore A
Tensile Strength: 24.1 MPa
Elongation: 510%
Water Absorption: 0.9%

⭐ **WATERSTOP Classification System by Winwinpool
(Type A / AA / B / BB / C / CC)**

Waterstops are categorized by width, number of ribs, and thickness to match specific engineering requirements and joint types.
