Quick Overview

    Bituthene ® System 4000 is a 1 /16 in. (1.5 mm) flexible, pre-formed waterproof membrane which combines a high performance, cross laminated, HDPE carrier film with a unique, super tacky,self-adhesive rubberized asphalt compound.

    System 4000 Surface Conditioner is a unique, water-based, latex surface treatment which imparts an aggressive, high tack finish to the treated substrate.It is specifically formulated to bind site dust and concrete efflorescence, thereby providing a suitable surface for the Bituthene System 4000 Waterproofing Membrane.

  • Cold applied — simple application to substrates, especially at low temperatures
  • Reduced inventory and handling costs — System 4000 SurfaceConditioner is included with each roll of membrane
  • Wide application temperature range — excellent bond to self and substrate from 25°F (-4°C) and above
  • Overlap security — minimizes margin for error undersite conditions
  • Crosslaminated, high density polyethylene carrier film — provides high tearstrength, puncture and impact resistance
  • Flexible—accommodates minorstructural movements and will bridge shrinkage cracks
  • ULapproval ClassAFire Rating—see approvalssection inside for details

Bituthene is ideal for waterproofing concrete decks where in-service temperatures will not exceed 130°F (54°C). It can be applied to split slab construction such as in plaza areas and parking decks. Interior uses may include mechanical rooms, laboratories, kitchens and bathrooms. (For below grade applications,see “Below Grade Waterproofing Bituthene System 4000.”)

Bituthene is 1 /16 in.(1.5 mm)thick, 3 ft(0.9 m) wide and 66.7 ft (20 m) long and is supplied in rolls. It is unrolled adhesive side down onto concrete slabs primed with System 4000 Surface Conditioner. Continuity is achieved by overlapping a minimum 2 in. (50 mm) and firmly rolling the joint.

Bituthene is extremely flexible. It is capable of bridging shrinkage cracks in the concrete and will accommodate minor differential movement throughout the service life of the structure.
