MasterJoint 910

Polymer Based Water Swelling Joint Bar

What is MasterJoint 910?

MasterJoint 910, is a new generation water swelling joint bar that expands on water contact due to its three dimensional polymer chain structure.

Recommended Uses

• Pools

• Water tanks

• All kinds of structures that are exposed to sea water

• Treatment plants

• Tunnel segments

• All construction joints subject to water

• Steel profiles and pipes penetrations

• As flange in PVC pipe penetrations

Features and Benefits

• Easy to apply compared to conventional weterstops and minimizes negative risks that may cause from workmanship.

• When MasterJoint 910 contacts with water, it expands in an ideal speed and doesn’t damage green concrete.

• Three dimensional polymer chains does not change its structure and its homogeneity during swelling.

• It expands up to 170%.

• This dimension change enables the material to form a water barrier in the reinforced concrete structure and fill in possible gaps.

• Resistant to various chemicals.

• Resistant to oil, fuel-oil, and various solvents.

• Resistant to waters that have high salt concentration.

• Its molecular structure is not affected from volume increases due to freezing of the water it contains.

• Resistant to microorganisms.
