Premium Quality Bentonite Water Swellable Bar 20x10mm

Product Description

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.

Technical Specifications:

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.
