DampBlock DPC
DampBlock DPC
DPC DampBlock is asphalt saturated damp proof course (DPC), manufactured in an advanced continuous calendaring process by fully saturating a fiberglass materials which act as a carrier with oxidized bitumen on both sides & coated with fine sand as upper & lower surfaces.
Intended Use
DPC DampBlock can be used for roofing and waterproofing applications with high dimensional stability requirements and subjected to considerable movements induced by stresses , and to critical weathering conditions.
DPC DampBlock membranes are particularly recommended for the following Areas of Applications :
-
Damp proofing course layer
-
Water proofing of simple works : ( substrates – retaining walls – foundations – bridge decks & wet areas )
-
Many other purposes where high strength is required.
-
Hot Mopping method using Technoxide oxidized bitumen.
-
Mechanical fastening if used as underlay.
Major Features
-
Flexible for quick & easy installation
-
Fine sand applied to both surfaces to reduce sticking.
-
Perfect U.V. resistance.
-
Improved chemical resistance to acidic and alkaline solutions.
-
Enhanced thermal resistance under a wide range of temperature fluctuation.
-
Adequate isotropic mechanical properties.
-
Absolute impermeability to water.
Finishes
The lower surface of DPC DampBlock is laminated with a thin Polyolefinic film (Sacrifice Layer) while the upper surface is covered with Polyethylene film or White Fine Sand.
Method of Application
DPC DampBlock is usually applied by using a propane torch or a hot air generator as well as by mechanical fastening. It can also be applied using special adhesives in cold or hot applications. The substrate surface must be clean, dry, smooth, and free from any irregularities. According to the surface conditions, a coat of TECHNOBIT PRIMER maybe required prior to the application of the membrane.
DPC DampBlock can be applied to the substrate fully bonded, semi bonded or loose laid, and the method of adhesion to the substrate shall be decided according to the waterproofing system design. Side laps should be from 8 – 10 cm, while end laps should be from 12 – 15 cm. For more information on application refer to TECHNOBIT application guide.
