Drybase Tanking Slurry

Drybase Tanking Slurry is a cementitious, ready-mixed, efflorescence-free surface waterproofer with hydrophobic properties, resistant to water and moisture. Drybase Tanking Slurry is applied to surfaces such as concrete, masonry and render, which have to be sealed and protected against the influence of water and moisture.

Drybase Tanking Slurry is waterproof (tested up to 7.0 bar). It can be employed against active and passive water pressures. Drybase Tanking Slurry is safe to use with potable water. The initial and final bonding capability of Drybase Tanking Slurry is excellent, making it suitable for application to horizontal and vertical surfaces. It is durable, resistant to frost and heat setting, and permeable to vapour. Drybase Tanking Slurry is not a decorative material. Consult Safeguard Europe Ltd technical literature for details. Safeguard Europe Ltd can also provide a design and specification service and it is recommended that they are consulted early in the design process.

Substrate:

Sound stable surfaces.

Preparation:

The substrate to be sealed must be firm and relatively even, and it’s surface free from voids, gaping cracks or ridges. Bitumen, oil, grease or remains of paint have to be removed by suitable means. Laitance and unsound concrete have to be removed by bush hammering or sand blasting. The substrate should be well prewatered and slightly damp at the time of application.

Select from: 1.5 mm (for ground moisture sealing) / 2 mm (for pressureless surface water and seepage) / 3 mm (for water under pressure)

Application:

Drybase Tanking Slurry may be applied with a masonry bush, trowel or spray equipment. Do not apply at temperatures below +5°C, or to a frozen substrate. A maximum of 4 kg/m² can be laid in one application. Provide suitable protection against extreme weather conditions whilst setting.

Finish:
