Hydrotite CJ Type Expanding Sealer 10 Metre Roll

Professional-Grade Waterproofing Solution

As a retailer of hot tub spare parts, I’m excited to offer this premium Hydrotite CJ Type Expanding Sealer. This professional-grade 10-metre roll provides exceptional sealing capabilities for concrete joints and structural gaps in hot tubs, pools, spas, and water features.

Product Overview

Hydrotite CJ Type Expanding Sealer is an advanced hydrophilic waterstop designed specifically for permanent waterproofing of construction joints, penetrations, and structural gaps. Unlike conventional sealants, this remarkable product expands when exposed to water, creating an unbeatable compression seal that prevents water infiltration even under significant pressure.

This high-performance 10-meter roll is ideal for new installations, renovations, or repairs of concrete hot tubs, pools, and water features. The specialized formula is engineered to provide decades of reliable service, making it the preferred choice of professional installers and serious DIY enthusiasts.

How It Works

The innovative hydrophilic technology in Hydrotite allows it to expand up to 8 times its original volume when in contact with water. This controlled expansion creates tremendous pressure against the concrete surfaces, forming a watertight seal that becomes stronger as water pressure increases. Once installed, the material maintains its flexibility and sealing capabilities through countless wet/dry cycles, ensuring permanent protection.

Key Applications

• Sealing construction joints in concrete hot tubs and pools
• Waterproofing pipe penetrations and structural connections
• Creating watertight interfaces between different building materials
• Repairing leaking concrete joints in existing installations
• Sealing cracks and gaps in water-bearing structures
• Creating custom gaskets for unusual waterproofing challenges

Installation Guide

For optimal results, I recommend applying Hydrotite to clean, smooth concrete surfaces. The sealer can be adhered using construction adhesive specifically designed for hydrophilic waterstops. Cut the material to the desired length, apply adhesive to the substrate, and press the Hydrotite firmly into place.

It’s important to protect the installed sealer from premature exposure to significant moisture before the concrete pour or structure completion. For maximum effectiveness, ensure adequate concrete coverage around the waterstop, following manufacturer’s specifications for your particular application.

The Professional Advantage

This premium Hydrotite CJ Type Expanding Sealer represents the gold standard in concrete waterproofing technology. The 10-metre roll provides enough material for substantial projects, while the specialized formulation ensures decades of reliable performance without degradation or maintenance requirements.

For serious hot tub and pool installations or repairs, this professional-grade sealer delivers peace of mind that conventional products simply cannot match. The ability to create custom, perfectly tailored waterproofing solutions for unique structural challenges makes this an invaluable product for demanding applications.

Hydrotite CJ Type Expanding Sealer is the definitive solution for permanent, high-performance waterproofing of concrete structures in the most demanding aquatic environments.
