Description Technical features and measures Related documentation

DANOPOL DW HS 1.2 BIO is a synthetic PVC plasticized membrane, light blue, reinforced with polyester net carrier. Designed for drinkable water tanks waterproofing, incorporates biocides in its formulation to prevent the formation of algae, fungi and any other type of organisms harmful to humans. U.V. resistant.

Instruction for Use

Preparation of the substrate:

The surface of the base substrate shall be resistant, uniform, smooth, clean, dry and free of foreign bodies.
Polyester geotextiles, type Danofelt PY 300 or higher, shall be used as a separating or protective layer.
DANOSA recommends a solution that is not adhered to the substrate, welding the overlaps with a hot air machine and pressure roller.

STRONG>Laying the waterproofing sheet:

The joint between sheets shall be made by means of thermoplastic welding, with a hot air welder. The overlaps shall be at least 5 cm and the welding of the lower sheet with the upper one shall be at least 4 cm. Immediately after welding, the joint shall be pressed with a roller, thus ensuring a homogeneous joint. To check the joints, a blunt metal needle (with a rounded tip with a radius between 1 mm and 3 mm) shall be used to physically check the joints by passing it along the edge of the joint.
On the vertical and horizontal perimeter, laminated plates mechanically fixed to the substrate shall be used in order to weld the waterproofing sheet on its surface. If the tank is more than 2 metres deep, it is recommended that intermediate laminated sheets be used on the vertical face to ensure the flatness of the sheet.
A laminated profile fixed to the vertical face should be used to crown the tank, and the sheet should then be welded to its surface. The profile shall be sealed with ELASTYDAN 40 PU Grey polyurethane mastic or equivalent, never in contact with the sheet or the water contained in the tank.
