Henkel Polybit Watertite T 2015 System

Watertite T 2015 is a 3 layer waterproofing system with 2 base layers of 4mm thick SBS modified bituminous membrane protected with a polypropylene fleece surfaced 3.5mm thick self-adhering bituminous membrane. It is designed for deep structures up to 15 meters from the ground level where high hydrostatic pressure is expected.

Fields of application include:

- Commercial buildings with deep excavations

- Deep structure near to sea

- Structures under high hydrostatic pressure

Specification

SPECIFICATION
Characteristics:
- Loosely laid system
- Remains independent of the structural movements and settlements
- Mechanical adhesion of polypropylene fleece of the top layer of the system with concrete forms the system as a part of the concrete structure
- Excellent resistance to water & vapor pressure
- Good dimensional stability under tension
- Excellent flexibility, tensile and tear strengths
- High puncture, wear & fatigue resistance
- High resistance against water borne chemicals
- Exhibits good low temperature flexibility
- Excellent UV resistance
Components:
1. Polyprime SB: Quick drying solvent based low viscosity bitumen primer. Conforms to ASTM D41, with a solid content of at least 40%.
2. Bituplus E4180: 2 layers of bituminous waterproofing membrane, modified with SBS polymers for excellent waterproofing and low temperature flexibility properties.
3. Bistustick R400: Polymer modified bituminous self adhesive anti-root, waterproofing and protection membrane.
