MasterSeal® 910 (Formerly known as Masterflex 610)

Water swelling waterbar for joints

DESCRIPTION
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 a component of the BASF pilecap waterproofing and watertight jointing systems.

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.

FUNCTIONAL BEHAVIOR
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.


PACKAGING
20 x 10mm (± 5%) 30 linear metres per carton.


INSTALLATION PROCEDURE
PREPARATION:

  • All joints to be waterproofed with MasterSeal 910 Waterbars must first be cleaned. Free standing water and sharp protrusions must be avoided.
  • MasterSeal 910 Waterbars can be installed on moist or frozen surfaces.
  • MasterSeal 910 Waterbars are resistant to most ordinary mould release agents, but if in doubt the installed waterbar should always be protected from accidental exposure to form release agents.

PLACING:

  • For normal joint widths of 200-400mm, MasterSeal 910 is placed in the middle of the joint.
  • For added safety thicker walls can be fitted with 2 waterbars.
  • MasterSeal 910 Waterbars are glued into the joint with a special adhesive for MasterSeal 910 Waterbars.
  • On vertical surfaces the MasterSeal 910 is temporarily fixed to the construction joint with a nail until the adhesive dries.
  • MasterSeal 910 Waterbar MUST always be secured so that the waterbar is in close contact with the surface of the substrate otherwise the full waterproofing effect will not be obtained.
  • After placing the MasterSeal 910 Waterbar the joint area should be kept clean and free of loose dirt and stones before concreting. The minimum concrete cover of MasterSeal 910 Waterbar is 80mm.

MATERIAL COMPOSITION
MasterSeal® 910 (Formerly known as Masterflex 610)

BUTT JOINTS:
MasterSeal 910 Waterbars should never be glued
at butt joints, but laid with a 20mm overlap.

TECHNICAL PROPERTIES

  2. Water seepage (when placed in expansion joint): none
  3. Application temperatures: -30°C to +50°C
  4. Freeze / thaw resistance: no influence before and after concreting

SAFETY PRECAUTIONS
As with all chemical products, care should be taken during use and storage to avoid contact with eyes mouth, skin and foodstuffs. If accidentally ingested, seek immediate medical attention. Reseal containers after use. For further
information, refer to material safety data sheet.


STORAGE
Store under cover out of direct sunlight and protect from extremes of temperature. In tropical climates the product must be stored in an air conditioned environment.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage and
disposal instructions refer to the Material Safety Data Sheet.
