⭐ **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.

General residential pool construction and reliable waterproofing of standard joints.
Specifications:
Width: 6"
Triple-rib profile
Thickness: 5 mm, lightweight and easy to install

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

The New Year holiday is a time when many families travel to other provinces or overseas, leaving their homes unoccupied for several days. For homeowners with swimming pools, this often leads to concerns that the water may turn green, develop unpleasant odors, or require costly cleaning and water replacement upon return.
In reality, closing a swimming pool for 7–10 days is not difficult if the correct water care principles are applied. The key is proper water preparation before leaving, using the right chemicals to work in place of daily maintenance. This approach helps control algae growth, bacteria, and the accumulation of dirt during periods when the pool is not in use.
This one-time, 10-day pool care method is designed for residential pools and can be applied to both homes without automatic control systems and those equipped with Smart Home or Smart App monitoring. It allows pool owners to reduce system operation while still maintaining stable water quality throughout the holiday period.
When chemicals are selected correctly and adjusted according to pool size, homeowners can return from their trip to find clear, clean water. With minimal effort—such as vacuuming settled debris—the pool is ready for immediate use, eliminating the need for draining or refilling and ensuring a stress-free return home.
