Arisons Bentonite rubber waterstop Type PN with unmatched durability and water sealing capabilities. Manufactured NON-BENTONITE, modified chloroprene rubber, more than doubles its original size (400% in 36 days) when exposed to water. This expansion creates an effective compression seal within joints of limited to no movement. It can expand and reexpand unlimited times with virtually no loss of physical properties. Additionally, Type PN has excellent resistance to many chemicals, is heat-resistant, and is safe for drinking water.
REQUEST A QUOTEBentonite waterstops have become essential in modern concrete construction, ensuring reliable watertight performance for below-grade structures including parking garages, underground warehouses, commercial spaces and tunnels. As a professional provider of specialized below-grade waterproofing solutions, Arisons offers a full range of high-quality, cost-effective hydrophilic waterstops engineered to satisfy the strict water containment demands of contemporary construction projects.
When in contact with water, these Bentonite waterstops expand and exert swelling pressure against the surrounding concrete, effectively sealing potential leak paths along construction joints. The resulting seal is continuous and long‑lasting, performing well in straight joints and around complex details such as pipe penetrations and fittings. Unlike conventional waterstops that depend mainly on adhesion, Arisons Bentonite waterstops seal actively through expansion, making them highly adaptable for joints constructed with various materials.
Certification and Specifications
All waterstops must meet certain classes of ASTM C1619, depending on the specifications for a project. Generally, sanitary projects will require C1619 Class A (standard rubber) or B (oil-resistant rubber) and stormwater projects will reference C1619 Class C (standard) or D (oil-resistant).
Our factory has been ISO 9001 certified since 2005. In subsequent years, we have successively obtained ISO 14001, CE, EN 681 and SGS certifications, as well as other internationally recognized qualifications.
FAQ
What materials are used in your Bentonite waterstop products?
Our Bentonite waterstops are made from sodium bentonite combined with modified chloroprene rubber. This composition ensures excellent swelling capacity, chemical and heat resistance, and safe use in drinking water applications, meeting ASTM C1619 and ISO certifications.
Can ARISONS provide custom rubber seals for specific project needs?
Yes, we offer customized solutions for custom rubber seals tailored to your project requirements. Our experienced R&D team works closely with clients to develop precise dimensions and performance criteria, ensuring reliable integration into your waterproofing systems.
How should Bentonite waterstops be installed for optimal performance?
We recommend embedding the Bentonite waterstop centrally within concrete construction joints where water-tight sealing is critical. Proper installation ensures the strip expands upon water contact to block leakage. Our technical team can provide guidance on reliable practices and joint design compatibility.
Do you supply Bentonite waterstops for international logistics and large-scale projects?
Yes, as global rubber seal suppliers, we support both small-batch and mass bulk orders. Our integrated production facilities and rigorous quality management enable consistent delivery worldwide, ensuring your construction requirements for durable waterproofing are met reliably.
