Acrylic polymer based bentonite-free waterstop tape is a waterproofing material that swells up to 900 times its own volume when in contact with water, filling all cracks, pores and capillary gaps in concrete and waterproofing concrete joints.
Acrylic Intumescent Tape Working Principle
Volume changes in contact with water do not impair its structural properties. Hydrophilic tape, which returns to its original shape under dry conditions, works in an infinite cycle by swelling again when it encounters water.
Acrylic Intumescent Tape Application Areas
- Cold joints, curtain concretes, shoring curtains, bored pile perimeters, pipe entrances,
- In construction joints of all kinds of structures such as concrete curtain and slab joints, pipe and steel element transitions in wall and floor slabs, prefabricated concrete joints, cable ducts,
- Cold joints in foundation and curtain concrete joints, pools, joints of old and new concretes,
- Retaining and diaphragm walls,
- Tunnel constructions and drainage systems,
- Water tanks, treatment plants and pools, water canal constructions,
- At the joints of steel profiles and pipes with concrete,
- Waterstop flange at PVC pipe inlet and outlet,
water-repellent tape should be used to ensure water impermeability.
Acrylic Intumescent Tape Features
Easy and fast to apply.
No hot welding required.
Elastic. Provides a practical solution for corner turns.
It has a very high inflatable capacity. It does not disintegrate, decompose and maintains its integrity during and after swelling. Maintains its elastomeric properties even at the maximum swelling stage.
Resistant to chemicals, calcareous and salty waters and oils. It does not swell and decompose even in salt water.
Since it swells at an ideal rate in a controlled manner, it does not swell suddenly during fresh concrete casting.
Acrylic Intumescent Tape Surface Preparation
Ensure that the application surface is dry and clean. Do not apply on wet, icy, oily, muddy and dusty surfaces and in rainy weather. In order to prevent crack reactions that may occur in the concrete, it is recommended that the concrete thickness around the swelling tape should be 8-12 cm.
Acrylic Intumescent Tape Application Method
Inflatable tapes should be applied to the center point of the joint section. The intumescent tape should be applied on a dry and smooth surface.
Usually the assembly is freely stacked,
If desired, nailed to the surface at 30-40 cm intervals,
If desired, the adhesive can be applied with polyurethane sealant or EPDM sealant.
Each of the bands can be joined by overlapping 10 cm on each other or 10 cm side by side without overlapping the joints. It should not be used in expansion joints.
Acrylic Waterstop Tape Expansion Pressure
The pressure depends on the quality of the concrete, the stiffness of the concrete structure surrounding the product, which is affected by voids, openings and other weaknesses. In an ideal concrete structure, the material can develop up to 10 bar swelling pressure.
Acrylic Waterstop Tape Working Temperature
It can operate between -20 C and +50 C degrees.
Acrylic Inflatable Tape Sizes
05 mm wide x 20 mm long, 1 roll is 20 meters.
1 roll is 10 meters, 10 mm wide x 20 mm long.

Features and Benefits of Acrylic Waterstop Tape
– Thanks to its flexibility, the acrylic waterstop tape prevents water infiltration and acts as a waterproof barrier against the movement and expansion of concrete joints.
– Acrylic waterstop tape provides resistance to corrosive elements, further protecting the concrete structure.
How Does Acrylic Waterstop Tape Work?
Before pouring the concrete, acrylic waterstop tape is applied to the cold joint surface and forms a continuous seal.
As the concrete is poured, the acrylic tape creates a strong and watertight bond between the two concrete sections.
The flexibility of the tape allows it to adapt seamlessly to the concrete surface, preventing water ingress even under dynamic conditions.
Acrylic Waterstop Tape Applications
Underground structures such as basements, tunnels and retaining walls are weak points prone to water infiltration. Acrylic tape should be used at these application points to seal cold joints and prevent water leakage.
Water retention structures, including reservoirs, swimming pools and water treatment plants, require effective waterproofing measures. Acrylic waterstop tape provides waterproofing, preventing leaks and maintaining the integrity of these structures.
Commercial and residential buildings use acrylic waterstop tape in a variety of applications including foundations, elevator pits and parking lots to ensure dryness and prevent structural damage.
Acrylic Intumescent Tape Ease of Installation and Cost
Surface preparation and installation of acrylic waterstop tape requires easy, practical workmanship.
It can be implemented quickly and efficiently.
Construction time is short and associated costs are low.
Compared to traditional cold joint sealing methods such as bulk sealants or bentonite waterstop tape, acrylic waterstop tape is a more costly but more functional and user-friendly waterproofing material.
