the ecoseal gna closed-cell design gives the joint a +/-50% movement capability, accommodating thermal and settlement movement between the slabs while staying bonded and watertight.
the continuous membrane nature of the gn-a series, combined with its innovative installation method, provides superior waterproofing. by eliminating anchor bolt penetrations, the system prevents water ingress at the finished floor level and protects the reinforcement layer of the slab from potential water damage
engineered to withstand pedestrian and light vehicular traffic, this system is well-suited to areas experiencing continuous use, reducing maintenance needs while maintaining integrity
this video demonstrates the installation process, perfectly designed for easy installation for durability and reliability
The system is customizable to specific project requirements, with variable sizes, dimensions to suit a wide range of applications
