Premium Quality Bentonite Water Swellable Bar 20x10mm

About Premium Quality Bentonite Water Swellable Bar 20x10mm

A Bentonite Water Swellable Bar 2010 mm is a waterproofing product used to seal construction joints, expansion joints, and cracks in concrete. The bar is made from bentonite clay, which swells upon contact with water, creating a strong, flexible seal. This type of bar is often used in civil engineering projects where waterproofing is critical, and it provides an effective barrier against water infiltration.

---

Applications:

• Water retaining structures like tanks and reservoirs

• Basement walls and foundations

• Subway tunnels and sewage systems

• Concrete slabs

• Retaining walls

• Expansion and construction joints

---

How It Works:

1. Swelling Action: When exposed to water, the bentonite bar swells up, filling gaps and voids in the joint or crack. This creates an impermeable seal that stops water from passing through.

2. Adaptable to Movement: As the structure moves due to temperature changes or settling, the bentonite bar can expand and contract, maintaining the seal.

3. Self-Healing: If the bar is damaged, it can swell again upon contact with water, effectively sealing any new gaps that may form.

---

Advantages:

• Highly effective waterproofing due to the swelling action of bentonite

• Self-healing properties (swells when water is present)

• Easy to install in formwork or pre-existing structures

• Environmentally friendly (natural bentonite clay)

• Durable and resistant to UV, chemicals, and aging

---

Installation Tips:

• Placement: Usually placed in construction or expansion joints, where it can expand when exposed to water.

• Fixation: The bar can be glued, stapled, or simply placed in the joint during construction.

• Compatibility: Works well with concrete, steel, and other construction materials.

Superb Water Sealing Performance

The bentonite water swellable bar delivers unmatched hydro-expansive characteristics, swelling up to 300% of its volume when exposed to water. This makes it especially effective as a waterstop in critical joint areas of concrete structures, providing lasting peace of mind against leaks and seepage.


Engineered for Versatile Construction Needs

Suitable for a wide temperature range, the bar is built to handle harsh climate variations between -20C and +70C. Its advanced composition of sodium bentonite and rubber ensures both mechanical strength and flexibility, catering to diverse applications in infrastructure and commercial projects across India.


Effortless Installation and Maintenance

Featuring a user-friendly smooth, dust-free surface, this water swelling bar bonds easily to surfaces with adhesive, streamlining the installation process. With low maintenance demands and lasting durability, it's a practical and efficient waterproofing option for a wide range of industry professionals.
