Product Introduction
HDPE waterproof board is also known as geomembrane. Generally, geomembranes with a thickness of ≥0.8mm
are called waterproof boards, and those with a thickness of 0.8mm are called geomembranes. It is a kind of anti-seep
age material made of high molecular polymers as the basic raw material, and is divided into homogeneous waterproof
boards and composite waterproof boards.
Performance features
Excellent anti-seepage performance; High barrier property; High puncture resistance; Resistant to acids, alkalis and
many chemical substances; Excellent elongation and wear resistance; Good dimensional stability; Good adhesion; It is
convenient for construction.
Strength - Under the same gram weight specification, the tensile strength in all directions is higher than that of other
needle-punched non-woven fabrics.
Uv resistance - It has a very high UV resistance.
High-temperature resistance - maintaining structural integrity and original physical properties at high temperatures.
Permeability and planar drainage - The waterproof board is relatively thick and formed by needle-punching, featuring
excellent planar drainage and vertical water permeability, which can be maintained for many years.
Creep resistance - The creep resistance of the waterproof board is superior to that of other geotextiles, thus ensuring
good long-term performance. It can resist the erosion of common chemical substances in soil as well as the corrosion
of gasoline, diesel and other substances.
Ductility - The waterproof board has a good elongation rate under a certain stress, which enables it to adapt to uneven
and irregular base surfaces.
Function and application
Urban waste landfill, coal ash dam treatment, roads, railways, drainage projects, water conservancy, tunnels, anti-seepage
of embankments, DAMS and gates, anti-seepage of liquid storage reservoirs, water, oil and liquid transportation channels,
anti-seepage of solid waste storage sites, roof anti-seepage, moisture-proofing of basements, underground warehouses
and underground garages of buildings, pile membrane cofferdams, land reclamation from the sea, wharf projects, etc.
