Aquastrip

Application

  • For use in the sealing of manhole chambers, inspection chambers, box culverts and other pre-cast units.
  • For creating a watertight seal between pre-cast units.
  • On highways projects where the standard BD 31 2001 is required.
  • Waterproofing of underground pre-cast walkways.
  • Joint sealing of precast units used in water management routes.
  • Sealing of precast units used in biogas chambers.

Description

Aquastrip is an easy-to-use, high performance and cost-effective strip for joining precast concrete manholes, inspection chambers, shafts, caissons, ogee pipes and box culverts. Tested to BS, EN, ISO, DIN and ASTM standards, Aquastrip provides a flexible and watertight seal against pressures in excess of 5 bar. It is a polymer-modified, bituminous compound incorporating temperature extenders. Used with rapid-drying Aquastrip Primer for increased adhesion.


Features and benefits:

  • Composition to BS 6213: 1982 for jointing concrete, culverts, subways, water retaining and water excluding structures.
  • Tested to BS EN 1917 - European Standard for Concrete Manholes and Joints.
  • Performance exceeds the 0.5 bar/ 15 minutes water test. Enables the concrete manufacturer to supply units complying with the new standard.
  • Variety of cross-sections designed to seal all types and sizes of joints in manholes, inspection chambers, ogee pipes and box culverts.
  • In manholes, Aquastrip meets the joint sealant requirement of 'FWR Materials Selection Manual 1993', UKWIR 'CESWI' (5th edition, 1998) and WRc 'Sewers for Adoption' (5th edition, 2001).
  • In box culverts, Aquastrip meets the joint sealant requirements of CIRIA 'Culvert Design Guide 1997' and 'Highways Agency Design Standard BD 31, 2001'.
  • Aquastrip has a wide temperature tolerance range with improved flexibility in cold weather for easier application and jointing.
  • Plastoelastic properties and high adhesion provide a permanent, watertight seal during and after settlement, ground movement, side loadings etc, as required by BS EN 752-3: 1997, European Standard for Drains and Sewers.
  • Resistant to sulfates, acids, alkalis, salts, groundwater, trade effluent, grease, sewage and micro-organisms.
  • Aquastrip enables the contractor to install watertight manholes, inspection chambers, drainage pipelines and culverts quickly and economically without the need for in situ concrete surrounds, while still meeting full life-cycle durability requirements.
  • Waterproof.
  • Improved flexibility in cold temperatures.
  • Easy application.
  • Resistant to sewerage and trade effluent.
  • Acid resistant.
  • For sealing all precast units.
  • High adhesion.
  • Durable.
