⭐ **WATERSTOP for Swimming Pool Construction
Selection Guide + Specifications
(Winwinpool Standard by Pool Size & Concrete Thickness)**

A waterstop is a critical rubber component used to prevent water leakage through concrete joints in swimming pool structuressuch as floor-to-wall joints, cold joints, and expansion joints in deep or commercial pools. Selecting the correct size and specification is essential for achieving long-term waterproofing performance and minimizing the risk of leakage.

Winwinpool waterstops are manufactured according to TIS 11352544 and AASHTO standards, ensuring structural-grade quality. Material properties include:

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, rib design, and thickness, allowing users to select the most appropriate model based on engineering requirements and the type of concrete joint involved.



TYPE A 8" / 3 Ribs / 9.5 mm Thick (Heavy Duty)
Recommended for concrete walls 25-30 cm thick

Best for:
The most demanding applicationsexpansion joints, hotel pools, deep pools, and infinity pools.

Specifications:

Width: 8" (approx. 200-203 mm)
Suitable for 25-30 cm pool walls
Triple-rib design for maximum anchorage
Thickness: 9.5 mm, capable of withstanding high water pressure
Ideal for joints with movement or requiring the highest safety margin


TYPE AA 8" / 3 Ribs / 5 mm Thick (Standard Heavy Duty)
Recommended for concrete walls 20-25 cm thick

Best for:
High-quality pool construction requiring performance but not at Type As extreme level.

Specifications:

Width: 8", suitable for 20-25 cm walls
Triple ribs improve bonding with concrete
Thickness: 5 mm, lighter and easier to install while maintaining performance
A cost-effective alternative to Type A for large residential or resort pools


TYPE B 6" / 3 Ribs / 9.5 mm Thick (Heavy Duty 6")
Recommended for concrete walls 15-20 cm thick

Best for:
Pools requiring strong structural performance but built with medium wall thickness.

Specifications:

Width: 6" (152 mm)
Triple-rib design for enhanced anchorage
Thickness: 9.5 mm for demanding structural loads
Ideal for areas requiring heavy-duty performance with smaller wall profiles


TYPE BB 6" / 3 Ribs / 5 mm Thick
Best for:
General residential pool construction and reliable waterproofing of standard joints.

Specifications:

Width: 6"
Triple-rib profile
Thickness: 5 mm, lightweight and easy to install
Suitable for floor-to-wall joints and cold joints without movement


TYPE C 6" & 8" / 2 Ribs / 9.5 mm Thick (Heavy Duty 2-Rib)
Recommended for concrete walls 20-30 cm (or 6" for 15-20 cm walls)

Best for:
Construction joints requiring high durability and thicker material.

Specifications:

Available in 6" and 8"
Two-rib design, easier to install
9.5 mm thick for high-pressure conditions
Ideal for projects that prefer 2-rib profiles but need heavy-duty performance


TYPE CC 6" & 8" / 2 Ribs / 5 mm Thick (Standard Grade 2-Rib)
Recommended for concrete walls 15-25 cm

Best for:
General residential pools, non-movement joints, and cost-effective waterproofing.

Specifications:

Available in 6" and 8"
Two-rib design suitable for standard applications
Thickness: 5 mm, easy to install and economical
Ideal for typical pool construction and non-critical joints

⭐ Professional Tips from Winwinpool Engineers
Match the waterstop width to the concrete thicknessnot the pool size
Use 3-rib models for areas with movement or high pressure
Use Heavy Duty (9.5 mm) for high-risk or multi-pour concrete joints
Use Standard (5 mm) for residential pools and non-movement joints
Always position the waterstop in the center of the concrete joint for full sealing efficiency
