Bituthene® System 4000 – Below Grade

Self-adhesive HDPE waterproofing membrane with super tacky compound for use with patented, water-based Bituthene® System 4000 Surface Conditioner

Product Description

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

Conveniently packaged in each roll of membrane, Bituthene® System 4000 Surface Conditioner promotes good initial adhesion and, more importantly, excellent permanent adhesion of the Bituthene® System 4000 Waterproofing Membrane. The VOC (Volatile Organic Compound) content of this product is 100 g/L. Architectural and Industrial Maintenance Regulations limit the VOC content in products classified as architectural coatings. Refer to Technical Letters for most current list of allowable limits.

bituthene system 4000 below grade application Bituthene® 4000Product Advantages

  • Excellent adhesion—special adhesive compound engineered to work with high tack System 4000 Surface Conditioner
  • Cold applied—simple application to substrates, especially at low temperatures
  • Reduced inventory and handling costs—System 4000 Surface Conditioner 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 under site conditions
  • Cross laminated, high density polyethylene carrier film— provides high tear strength, puncture and impact resistance
  • Flexible—accommodates minor structural movements and will bridge shrinkage cracks
  • Ripcord®—this split release on demand feature allows the splitting of the release paper into two (2) pieces for ease of installation in detailed areas

Use

  • Bituthene® membrane is ideal for waterproofing concrete, masonry and wood surfaces where in-service temperatures will not exceed 135°F (57°C). It can be applied to foundation walls, tunnels, earth sheltered structures and split slab construction, both above and below grade. (For above grade applications, see Above Grade Waterproofing Bituthene® System 4000.)
  • Bituthene® waterproofing membrane 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 sticky side down onto concrete slabs or applied onto vertical concrete faces primed with Bituthene® System 4000 Surface Conditioner. Continuity is achieved by overlapping a minimum 2 in. (50 mm) and firmly rolling the joint.
  • Bituthene® membrane 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.

Drainage

Hydroduct® drainage composites are recommended for both active drainage and protection of the membrane. See Hydroduct® product information sheets.
