Product Description

Rubber Waterstop Ring for Various Underground Constructions

Rubber waterstop ring is a ring-shaped waterproof material made of macromolecule inorganic water-absorbing swelling materials and refined rubber. It is commonly sleeved in the middle of the bolt or strainer and embedded in the cast-in-place concrete wall to achieve great waterproof effects. As it expands when exposed to water and seals the gap, therefore, it is also known as swellable waterstop ring or swellable seal ring.

Features & benefits:

*Simple structure and easy to construction.
*Nontoxic, Corrosion resistance, reliable quality;
*Speed up the construction progress, save labor, time and reduce the cost of raw materials.
*Simple working principle and strong visibility.
*Easy to be understood and accepted by the design, supervision, owner and construction parties.
*Up to 300% volume expansion rate.
*Reliable and durable, no leakage occurs during various construction process.

Specification

*Inner (outer) diameter: 14 (40), 16 (40), 18(40), 20 (45), 25 (50), 30 (60), 35 (60) mm;
*Thickness: 10 mm.
*Executive standard: GB/T18173.3-2002.

Low temperature test (-20 °C × 2 h)	No fragile

Installation

    In the concrete formwork, there are many gaps between the split bolts and the surrounding concrete. Pressure water will inevitably seep into these gaps along the split bolt and cause water leakage. If a swellable waterstop ring is provided in the middle of the split bolt, when the water seeps into the gap, the waterstop ring will expand and fill the gap after expansion to achieve waterproof effects.
