Yunnan Baoshan EVA Waterproof Board Environmentally friendly, lightweight, highly water-resistant and weatherproof, and easy to install.
Yunnan Baoshan EVA Waterproof Board Usage:
1. Yunnan Baoshan EVA Waterproof Board Can be applied for impermeable barriers in landfills, sewage treatment facilities, or waste residue disposal sites.
2. Yunnan Baoshan EVA Waterproof Board Applicable to river embankments, lake dams, tailing dams, sewage dams, as well as reservoir areas, canals, and storage ponds (pits, mines).
3, Yunnan Baoshan EVA Waterproof Board Suitable for waterproof lining in subways, basements, tunnels, and underground passages.
4. Yunnan Baoshan EVA Waterproof Board Can be applied to subgrade and other foundation salt-resistant impermeabilization.
5, Yunnan Baoshan EVA Waterproof Board Can be applied to horizontal seepage cutoff blankets in front of dikes and dams, vertical seepage barriers in foundations, construction cofferdams, and waste disposal sites.
6, Yunnan Baoshan EVA Waterproof Board Can be applied to both seawater and freshwater aquaculture farms.
7, Yunnan Baoshan EVA Waterproof Board Applicable to foundations for roads, highways, and railways; as well as waterproof layers for expansive soils and collapsible loess.
8, Yunnan Baoshan EVA Waterproof Board Can be applied to roof waterproofing.
Yunnan Baoshan EVA Waterproof Board Construction Preparation
(1) Before laying the Yunnan Baoshan EVA waterproof membrane, the initial support must be leveled to meet the flatness requirements for shotcrete: For sidewalls, D/L ≤ 1/6; for the arch crown, D/L ≤ 1/8 (where L is the distance between two adjacent convex areas of the shotcrete, and D is the depth of the concavity between these same convex areas). If these criteria are not met, apply a 1:2.5 cement-based waterproof mortar to achieve smoothness until the specifications are satisfied.
(2) The base surface must be free of sharp protrusions such as rebar, wire, and steel pipes; otherwise, they should be cut off at the root. At the cut-off areas, apply cement mortar to create a smooth, rounded curve, ensuring that the Yunnan Baoshan EVA waterproof membrane is protected from punctures.
(3) At tunnel cross-section changes or bends, the internal and external corners should be rounded with an arc radius of R > 50 mm.
(4) The base plate surface must be smooth and free of significant, noticeable unevenness or undulations.
(5) The strength of the sprayed concrete must meet the design specifications.
(6) During the construction of EVA waterproof boards in Baoshan, Yunnan, the base surface must be free of standing water. If standing water is present, either grouting to seal it or draining it away should be implemented, ensuring the base surface remains completely dry.
