Krack Fill

Fiber-reinforced sealant formulated to fill dynamic and static cracks up to 5 mm in plaster and masonry surfaces. Prevents water ingress while accommodating minimal thermal expansion.

What is the difference between Seal & Dry Flex and Seal & Dry HiFlex?
Flex is suitable for internal wet areas like bathrooms, kitchens, and water tanks where moderate movement occurs. HiFlex features superior elongation properties designed specifically for structures exposed to high thermal expansion, structural vibration, and continuous outdoor weathering.
Can Seal & Dry SBR be mixed directly with cement?
Yes, it can be mixed with cement and sand to form bonding slurries, waterproof screeds, or polymer-modified repair mortars to enhance bond strength and reduce water permeability.
Why use Fixoblock thin-bed mortar instead of traditional site-mixed sand-cement mortar?
Fixoblock reduces joint thickness from 12 mm to 2–3 mm, reducing thermal bridging, dead load, and material consumption while dramatically speeding up masonry installation and curing time.
What makes Powergrout Ns1 Flowable different from standard cement slurry?
Powergrout Ns1 contains special expansion agents that counteract dry shrinkage while maintaining controlled flowability without segregation, ensuring structural contact under equipment baseplates.
