Carapace SA

CARAPACE PET is a plastomeric waterproofing membrane manufactured in an advanced continuous calendaring process by saturating and coating a synthetic carrier a waterproofing compound made of special grade of bitumen, modified with APP polymers. While the modifiers enhance the thermal, mechanical, and aging properties of membrane compound mechanical characteristics. CARAPACE is produced using the non-woven continuous filament spun-bond Polyester carrier properties. CARAPACE is top layered with special Anti-Puncture film which gives the membrane its extra ordinary mechanical characteristics.

Intended Use

CARAPACE membranes are used in general purposes as general purpose waterproofing membranes in applications subject to moderate mechanical stresses in single or multi-layer systems for a variety of waterproofing requirements. CARAPACE membranes are particularly recommended for the following Areas of Applications :

  • Below grade Waterproofing & Damp Proofing.

  • Protection Layer in multi layer systems.

Major Features

  • Anti-Puncture – High Tear Resistance.

  • Improved chemical resistance to acidic and alkaline solutions.

  • Absolute impermeability to water.

Finishes

The lower surface of CARAPACE is laminated with a thin Polyolefinic film (Sacrifice Layer) while the upper surface is covered with Cross Laminated HDPE film.

Method of Application

CARAPACE membranes are applied by using a propane torch or by mechanical fastening. The substrate surface must be clean, dry, smooth, and free of any irregularities. According to the surface conditions, a coat of water base primers may be required, prior to the applications of the membranes. CARAPACE can be applied to the substrate fully bonded, semi bonded or loose lay, and the method of adhesion to the substrate shall be decided according to the waterproofing system design. Side laps should be from 12 – 15 cm. For more information on application refer to the TECHNOBIT Application Guide.
