This flexible GCL waterproof liner is widely used in building construction, particularly for roof gardens and basement waterproofing. It provides a continuous anti seepage barrier that protects structures from water infiltration.
Its flexible structure allows it to conform to complex building surfaces, ensuring complete coverage without gaps. Once hydrated, the bentonite forms a dense seal that prevents water penetration.
Compared with traditional waterproof membranes, this product offers better adaptability and self sealing capability, reducing maintenance requirements.
It is an ideal solution for urban construction projects where reliable waterproofing is essential.
