Product Details
Areas of Use
- Joints between precast concrete elements,
- Construction joints in cast-in-place reinforced concrete structures (such as cold joints between walls and foundations),
- As a watertight flange around pipe penetrations through reinforced concrete structures,
- Tunnel segments,
- Joints between slabs and pile cap foundations,
- Concrete and steel joints.
Advantages
- Easy to apply,
- Economical,
- Expands up to 500% upon contact with water,
- Features a protective coating that prevents premature expansion. Compared to standard swelling tapes, FOX SWELLING TAPE 520 starts expanding later. Under normal conditions, expansion begins approximately 7 days after water contact. This prevents unwanted swelling due to accidental exposure to water on construction sites (rain, etc.). It also prevents the formation of unwanted gaps between fresh concrete and the swelling tape before the concrete has properly set,
- Flexible and suitable for irregular substrates,
- Expands when exposed to water within concrete structures, creating a watertight seal,
- Retains its ability to expand again upon repeated water exposure,
- Broad chemical resistance range,
- Resistant to petroleum products, minerals, vegetable oils, and greases,
- Impact-resistant,
- Suitable for areas with fluctuating water levels and for use in contaminated or slurry water conditions.
