As people's understanding of bentonite continues to grow, its applications are expanding into various fields. In many developed countries, bentonite waterproof blankets have already become a standard solution for waterproofing projects. With China's rapid economic growth, there is a huge demand for reliable waterproofing materials across numerous construction projects.
As environmental protection and energy-saving regulations become more comprehensive, it is reasonable to expect that bentonite waterproof blankets—known for their excellent performance—will gradually replace traditional waterproofing materials. Their superior sealing properties and long-term durability position them as a leading choice in the waterproofing industry.
To ensure the effectiveness of bentonite waterproof blankets, it is crucial to prevent damage during installation and backfilling. Here’s how Hengruitong recommends avoiding punctures:
First, during transportation and handling, care should be taken to avoid any sharp objects that could scratch or tear the blanket. If damage occurs, a patch can be applied using a new piece of bentonite blanket. The patch should be at least 30 cm away from the damaged area on all sides. Before placing the patch, sprinkle some granular bentonite or bentonite pulp over the area. Adhesive may also be used to secure the patch. The size, consistency, and chemical compatibility of the filler must be approved by an engineer. For example, if the backfill contains high levels of calcium (such as limestone or marble), it is recommended to consult technical experts before proceeding.
The particle size of the backfill material should ideally be less than 25 mm. Use low-pressure mechanical equipment when placing the backfill. Always maintain at least 30 cm of soil between the geotextile bentonite mat and any machinery. In high-traffic areas, the backfill thickness should be no less than 60 cm to provide adequate protection.
During backfilling, be careful not to allow the material to enter the middle of the two layers of the swollen pad. When working on slopes, backfill should be placed from bottom to top to reduce pressure on the waterproof blanket.
