The roof is the outer protective structure at the top of a
building, typically serving to withstand external factors such as
wind and sun exposure, ensuring the building's durability and
sturdiness. Protective measures during roof construction are
indispensable. Today, Feiyang introduces the application of
polyaspartic polyurea in roof waterproofing.
Traditional roof waterproofing materials commonly include modified
bituminous felt, waterproofing membranes, APP modified bitumen,
polymer waterproofing rolls, and JS waterproofing paint.
Traditional roof waterproofing materials, such as bitumen,
waterproofing rolls, and APP, when exposed to sunlight, undergo
photoaging which can result in warping and cracking. Even if the
material itself doesn't warp or crack, it can still fracture due to
the warping and cracking of the concrete (caused by stress,
vibration, and other factors). Waterproofing rolls, in particular,
have numerous seams, which, under the effects of outdoor
photoaging, can accelerate leakage. Once leaks occur, pinpointing
the exact location becomes challenging.
Polyaspartic polyurea surpasses traditional waterproofing materials
in performance. It possesses excellent physicochemical properties,
including high tensile and impact strength, flexibility, wear
resistance, anti-slip properties, anti-aging, and corrosion
resistance. Moreover, the polyaspartic polyurea coating adheres
100% to the substrate, offering a seamless surface with superior
integrity and effective leakage prevention.
Due to its inherent flexibility, anti-aging properties, and
mechanical strength, elastic polyaspartic polyurea remains unbroken
even when concrete warps or cracks. Not only does it remain intact,
but it also firmly "grips" the concrete, providing both
waterproofing and protection. This elastic polyaspartic polyurea
waterproofing material is especially suitable for high-end building
structures' roof waterproofing, achieving a "once and for all"
solution.
