Arisons Bentonite 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.
Bentonite 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 swelling waterstop products?
Our swelling waterstop is made from modified chloroprene rubber with a non-bentonite formula, ensuring superior durability. This material offers excellent chemical and heat resistance while being safe for potable water applications, making it a reliable choice among rubber seal suppliers.
Can you customize rubber seals to fit specific project needs?
Yes, we provide customized solutions for a wide range of projects, including custom rubber seals designed to meet precise specifications. Our experienced R&D team develops tailored formulations and profiles to ensure compatibility with various concrete waterstop requirements.
How should swelling waterstops be installed in construction joints?
Installation involves positioning the swelling waterstop within the joint to ensure direct contact with concrete. Our products actively swell upon water exposure to form a tight compression seal. Proper installation enhances the effectiveness of the concrete waterstop in preventing leakage through joints.
What is the lead time and logistics support for bulk waterstop orders?
We operate advanced production lines capable of fulfilling both small-batch and mass bulk orders. Our integrated production base and strong QC team ensure timely delivery without compromising quality. Contact us for detailed logistics and order scheduling to meet your project's deadlines.
