MasterSeal 910 - Water swelling waterbar for joints
How does MasterSeal 910 work?
MasterSeal 910 Waterbar is suitable for all construction joints subject to hydrostatic pressure, on one or both sides. MasterSeal 910 provide simple but efficient waterproofing of construction joints. Movements in the joint, e.g. by shrinkage or settlement in the substrate, are taken up by the elastic profile of the MasterSeal 910 Waterbar. MasterSeal 910 has been successfully employed to waterproof joints where an opening of up to 5mm was deliberately created. Water pressure of up to 5 bar was sealed.
MasterSeal 910 is based on a newly developed polymer technology providing flexible polymer composites which have high chemical resistance capable of storing water in their molecular structure by increasing their volume.
Where previously MasterSeal 910 was available
in different grades for various exposure conditions.
A single version of MasterSeal 910 now resists
deterioration in the following conditions: In fresh
water and where the water has a high salt content
(sea water, brackish water), in construction with
high chemical exposure and/or exposure of
solvents, including oils and fuels.
MasterSeal 910 is a component of the Master
Builders Solutions pile-cap waterproofing and
watertight jointing systems. Consult your
representative for details.
What are the benefits of MasterSeal 910?
When in contact with water the MasterSeal 910 Waterbars will slowly increase in volume (swell) without changing the homogeneous structure of the polymer matrix. The increase in volume by the swelling action can be up to 200% (depending on type of water). The pressure of the swelling action will cause the MasterSeal 910 Waterbar to profile itself exactly into the joint filling all cavities and effectively stopping water seepage, even at high external water pressure.
The MasterSeal 910 Waterbars will not transport
water through their polymer matrix and thus not
act as a capillary duct. The swelling action is
limited to the sides exposed to water.
