DESCRIPTION

BITUSTOP PVC Waterstop are extruded from high-grade PVC compounds, designed for sealing movement and construction joints in reinforced concrete structures in blue color.

SPECIFICATION

Bitustop PVC Watertop is supplied in 12 meters to 20 meters per roll.

APPROVALS / CERTIFICATES

USES

Bitustop PVC Waterstop used in concrete for the sealing of construction and expansion joints, are embedded in concrete across and along the joint, to form a continuous waterlight diaphragm that prevents the passage of the fluid through the joint. The many shapes centrally and extemally placed allow lasting waterlight seals in any grade of construction design. They are typically used in water retaining and excluding structure such as:

  • reservoirs,
  • sewage tanks
  • dams
  • pools
  • basements
  • tunnels retaining walls etc.

STORAGE

  • No shelf life limitation if kept in cool and dry conditions.
  • Keep the products packed in a dry place.
  • Keep away from direct sunlight.
  • Store in original packaging until time of installation.
  • Protect from excessive heat, moisture and physical damage.
  • Avoid stacking in a way that may cause deformation of the waterstop profile.
  • Handle carefully to prevent bending, twisting or edge damage before installation.

ADVANTAGES

  • Will accommodate movement during construction and service life
  • Ease of use simple on-site jointing
  • Full range of factory welded and fabricated intersection pieces to suit every need
  • Brass reinforced eyelets edge flanges to ensure perfect fixing
  • Approval for use in contact with potable water

THE SELECTION AND REQUIREMENTS OF A WATERSTOP

a). Installation must be to ensure close and smooth joint.

  • A smooth profile is essential for the intimate compaction of fine quality dense concrete on its surface.
  • Resistance of maximum stress at the anchorage points consistent with their distant location from the joint where the section spans.
  • High level of rigidly facilitate installation consistent witheconomy and other necessary qualities.

b) Centrally placed waterstop; sections cast in slabs or walls in concrete structure can prevent water seepage. They fit to water retaining structures and in walls and slabs where pressure differentials may occur, i.e. reservoirs walls. They fit its joints in suspended slabs, ground floor slabs, vertical wall joints and lift joints.
c) Externally placed waterstop: it fits to basement and foundation construction where it supports firmly against back pressure, i.e. in or beneath water excluding structures where it is firmly supported by the base formation.
d) The width of waterstop is subjects to the thickness of the concrete, the size of the aggregate and the position of the reinforcement. Below are the smart tops for satisfactory choices.

  • The overall width of the waterstop should not be greater than that of the concrete into which is cast.
  • The distance between the concrete and the waterstop must be greater than half the width of the waterstop.
    For satisfactory compaction result, the width of the waterstop should be more than six times the size of the largest aggregate. (Example: for use in contraction joint, when the aggregate size is 20 mm, the width of the waterstop must be more than 6×20=120mm)
  • The distance between the waterstop and reinforcement members should be more than twice the size of the largest aggregate, or an unsatisfactory compaction may result.

STANDARD COMPLIANCE

  • BS 2782:320A
  • U.S. Corps of Engineers CRD-C 572-74

PRECAUTIONS

Hydrogen chloride mist and vapour may be released while welding PVC Waterstops. Therefore, forced ventilation must be provided or a suitable respirator used.

APPLICATION TOOLS AND EQUIPMENT

  • PVC welding machine for field jointing.
  • Welding jig or clamping device to ensure proper alignment.
  • Heating blade or welding knife for fusing PVC ends.
  • Cutting tools for trimming and preparing waterstop edges.
  • Personal protective equipment and adequate ventilation during welding operations.

HEALTH, SAFETY AND ENVIRONMENT

All safety measures should be observed during application. Fire extinguishers should be available on site. Care should be taken with gas, and torches should not be rested on finished surface or on any materials that can be scratched by flame or hot torch. Gloves and goggles should be worn by all workers during application.

Read, understand and follow all Material Safety Data Sheets and product label information for this product prior to use.
