Hebei Xinmian Waterproof Rock Wool Blanket: Special for Underground Projects in Beijing, Tianjin, and Hebei, Moisture-Proof and Non-Collapsing

The underground projects in the Beijing-Tianjin-Hebei region, such as the underground parking garages in Tianjin and the subway sections in Hebei, often suffer from moisture problems. Standard rock wool tends to collapse after absorbing moisture.

Hebei Xinnian Building Materials Co., Ltd. has developed its waterproof rock wool batts specifically for such scenarios: The core material is treated to be hydrophobic, with a water absorption rate below 3%, ensuring complete integrity even when the underground humidity reaches 90%; the fabric is made of PVC waterproof composite fabric, with double-sealed seams, achieving a waterproof rating of IPX5.

In 2023, a metro line 2 project in Shijiazhuang utilized the product for pipe segment insulation. In areas with high groundwater levels, rock wool has been used for one year without absorbing moisture or deforming, and there have been no signs of dampness cracks in the concrete pipe segments.

As a local service provider in the Beijing-Tianjin-Hebei region, Hebei Xinmian Building Materials Co., Ltd. offers on-site survey services. They can be on-site within 24 hours in cities like Tianjin and Baoding. Tailoring waterproofing solutions based on the depth and humidity of underground projects, they also coordinate local construction teams for installation, ensuring durable and hassle-free underground insulation.
