Great Ocean Waterproof
סרט עמיד למים
At Great Ocean Waterproof, we redefine structural protection. Our professional-grade waterproofing tapes are engineered with advanced adhesive technology to provide an impenetrable barrier against water ingress, even under extreme hydrostatic pressure. Whether you are sealing expansion joints, repairing roof leaks, or protecting critical infrastructure, our solutions deliver permanent bonding and unmatched weather resistance.
Benefits & Advantages
- Self-Healing Technology: Small punctures or cuts seal themselves over time, ensuring the integrity of the barrier remains uncompromised.
- Instant High-Tack Adhesion: No primer required for most surfaces. Bonds immediately to damp or dry concrete, masonry, and metal.
- Chemical & Aging Resistance: Resistant to acids, alkalis, and salts, making it ideal for underground foundations and coastal environments.
- High Elongation: Accommodates structural movement and thermal expansion without tearing or losing grip.

How to Use Waterproof Adhesive Tape (Step-by-Step Guide)
Applying our waterproof adhesive tape is simple and effective, requiring no special tools. Follow these steps for a secure, long-lasting seal. For specialized applications like roofs, our waterproof roofing tape offers enhanced durability against harsh weather.
- Prepare the Surface: Clean the area thoroughly to remove dirt, dust, grease, or old residue. Use a mild detergent and water, then dry completely with a cloth or allow it to air dry. For best results, ensure the surface is smooth and free of loose particles.
- Measure and Cut: Unroll the tape and measure the length needed for your repair. Cut it to size using sharp scissors or a utility knife. Avoid stretching the tape during cutting to maintain its integrity.
- Peel the Backing: Starting from one end, carefully peel off the protective backing paper. Handle the adhesive side minimally to prevent contamination.
- Apply the Tape: Position the tape over the area to be sealed and press it down firmly. Start from the center and work outward to eliminate air bubbles. Use a roller or your hand to apply even pressure for maximum adhesion.
- Smooth and Secure: Run your fingers or a smooth tool along the edges to ensure a tight bond. In curved or irregular surfaces, the tape’s flexibility allows it to conform without wrinkling.
- Allow Curing Time: Let the tape set for at least 24 hours before exposing it to water or heavy stress. Full adhesion strength is typically achieved within 48 hours, depending on temperature and humidity.
Tips for Success:
- Apply in temperatures above 50°F (10°C) for optimal bonding.
- For wet surfaces, dry as much as possible first—our tape can adhere to damp areas but performs best on dry ones.
- Safety First: Wear gloves to avoid sticky residue on your hands, and work in a well-ventilated area if using solvents for cleaning.

שאלות נפוצות
What surfaces can the waterproofing tape adhere to?
A: Our tape bonds effectively to a wide range of surfaces, including metal, plastic, rubber, concrete, wood, and glass. For optimal adhesion, ensure the surface is clean, dry, and free of oils or debris.
Is the waterproofing tape suitable for underwater applications?
A: Yes, it can be applied in damp conditions and forms a watertight seal once cured. However, for fully submerged uses like pools or aquariums, we recommend testing in a small area first.
How do I store the waterproofing tape to maintain its quality?
A: Store in a cool, dry place away from direct sunlight. Keep it in its original packaging to prevent dust accumulation and preserve the adhesive backing for up to 2 years.
Can the waterproofing tape withstand extreme temperatures?
A: Absolutely—it’s designed to perform in temperatures ranging from -40°F to 200°F (-40°C to 93°C), making it ideal for both hot and cold climates without losing flexibility or adhesion.
What makes your waterproofing tape different from standard duct tape?
A: Unlike regular duct tape, our product uses advanced butyl rubber or similar adhesives for superior waterproofing, UV resistance, and long-term durability, ensuring it doesn’t degrade or peel over time.
Is the waterproofing tape eco-friendly?
A: Yes, it’s made with non-toxic, eco-friendly materials free from harmful chemicals like VOCs. It’s safe for use in residential and commercial settings without environmental concerns.
How do I remove the waterproofing tape if needed?
A: Gently peel it off starting from one edge. If residue remains, apply a mild solvent like isopropyl alcohol or a citrus-based cleaner, then wipe clean. Avoid scraping to prevent surface damage.
Can I paint over the waterproofing tape?
A: Yes, once fully adhered (after 24 hours), you can paint over it with most latex or oil-based paints. For best results, lightly sand the tape surface for better paint adhesion.
What if the tape doesn't stick properly?
A: Common issues stem from dirty or wet surfaces. Clean thoroughly and apply firm pressure during installation. If problems persist, it may be due to incompatible materials—reach out for product recommendations.
Does the waterproofing tape come in different colors or sizes?
A: We offer it in black, white, and clear options, with widths from 1 inch to 4 inches and lengths up to 50 feet. Custom sizes are available for bulk orders—contact our sales team for details.
Customer Reviews & Testimonials
Hans Müller, Senior Site Manager, BuildTech GmbH 🇩🇪
★★★★★
“We have used many sealing products in our time, but Great Ocean’s waterproof adhesive tape stands out for its incredible bonding strength. We recently applied it to a large-scale bridge project in Hamburg, and the adhesion to cold steel and concrete was instantaneous. It’s a reliable component of our professional toolkit.”
Sarah Jenkins, Principal Architect, Azure Living 🇦🇺
★★★★★
“In high-end bathroom renovations, the smallest leak can cause catastrophic damage. We’ve switched exclusively to Great Ocean for our sealing membranes and water proof tape for shower installations. It handles corners and joints better than any other brand we’ve tested, giving our clients (and us) total peace of mind.”
Ahmed Al-Sayed, Facility Director, Desert Palm Properties 🇦🇪
★★★★★
“The climate in Dubai is brutal on building materials. We needed a waterproof tape for outdoor use that wouldn’t degrade or lose its tackiness under the 50°C sun. Great Ocean’s UV-resistant series has outperformed everything else. After two years of exposure, the seals are still flexible and perfectly intact.”
Michael Ross, Procurement Manager, NorthAm Hardware 🇺🇸
