Hydrophilic Rubber Water Stop

OXISTOP HP HYDROPHILIC is made of high performance modified rubber strips. The swelling action is the result of the interaction between water and hydrophilic groups which are part of the HYDROPHILIC molecular structure. Expansion of the water stop creates a positive seal against the face of the concrete joint and prevents the water entry into the structure through the protected joint.

FEATURES AND BENEFITS:

• Active protection – OXISTOP HP hydrophilic water stop swell in contact with water to form an effective compression joint.
• Simple application and jointing techniques.
• Slow expansion rate to prevent damage to freshly placed concrete during curing.
• Retains original shape after repeated swelling and contraction.
• Swelling properties are unaffected by long term wet / dry cycling. Made of synthetic rubber – Does not degrade during repeated wet / dry cycling.
• Sustains effective seal in wet conditions.

USES:

• OXISTOP HP Hydrophilic water stop can be applied against existing concrete and are simply installed by nailing or using a hydrophilic adhesive. In contact with water, hydrophilic strips react and swell by up to 300% of their original dimensions to form a compression seal.
• Hydrophilic strips are suitable for installation in low movement construction joints.
• OXISTOP HP HYDROPHILIC is used primarily for foundation wall slabs, slabs-on-grade, precast wall panels, manholes, pipe connections, box culverts, utility and wet wells, and potable water tanks.
