Basecrete Xtreme
3-IN-1 Waterproof Bondcoat with Fiber Additive
Basecrete Xtreme stands out with its 3-in-1 formula, merging advanced material science with practical application, offering superior resistance, versatility, and ease of application. Effective on ICF, EPS (Expanded Polystyrene), CMU wall (Concrete Masonry Unit) or under a stucco system when the concrete substrate requires added strength or durability, it not only waterproofs but also reinforces, using a fiber mesh additive. The additive of the fiber greatly increases flexural strength, which is essential in cooler climates that have freeze thaw cycles. It also improves surface movement like settlement, vibration or tensile strength, increasing durability and impact resistance.
Basecrete Xtreme sets a new benchmark in waterproofing for construction and renovation.
