PROPERTIES

High requirements flexible non-toxic waterproofing mortar. Its application to potable water tanks ensures the quality and sanitization of potable water as is certified for that purpose by the State General Chemical Laboratory of Greece (Ref:00178/015/000) The product meets the requirements of regulation EC 1935/2004 Article 28 of the Food and Drinks Code as well as those of German standards "KunststoffeimLebensmittelverkehr", § 1.3.2.5.

It provides excellent bonding strength and fully waterproofs the applied surfaces for many years. Because of its high flexibility and strong adhesion properties, it prevents the appearance of hairline or other shrinkage cracks after the application, while bridging the existing or future cracks of the substrate.

Due to its special compositionit helps preserving human health, by preventing the migration of hazardous substances into the water of watertanks. It provides excellent protection against carbonation and chloride attack of all cementitious substrates that is applied on, and it provides complete protection against sea water. It is certified as concrete surface protection product (c) per EN 1504-2.

APPLICATIONS

  • The HYDROSTOP WATERTANK applications are not limited to just potable water.
  •   The product is successfully applied for sealing surfaces made of concrete, brick, plaster, cement screed, stone etc. • It is also applied on surfaces with high water repellency requirements such as underground structures, foundations, tunnels and wet floors as well as structures that are subject to high hydrostatic pressure (positive or negative), such as basements (on the exterior, before backfilling and ‘therapeutically’ in the interior). • It is recommended for use on sloped roofs made of concrete before installing roof tiles.
  • It is applied on bridges, residential or athletic swimming pools, etc.
  •   It is also recommended for the ultimate roof waterproofing, protecting lightweight thermal insulation systems, and generally for the waterproofing of any mineral surface exposed to temporary or incessant moisture.
  • An additional use of the material is the effective sealing and waterproofing of areas to be planted, such as planters, rooftop gardens, etc. In those cases, the material is completely equivalent of asphalt roof membrane. Its main advantage is that WATERTANK can be applied without any joints. Because it possesses these properties, it is ideal for inverted roof insulation systems, before the installation of the insulation slabs we chose.
  •   It is a necessary component and part of the perimeter insulation, at ground level (sealing zone), withapplications on wall surfaces,of the External Thermal Insulation Composite Systems, amongst them,THERMOSEAL of DUROSTICK.

USE

Surface Preparation: Proper preparation ensures the perfect result. Concrete walls: Remove all formwork pins and wood, polystyrene and sharp protrusions. Cut all formwork pins 2-3cm deep and coat them with the corrosion inhibitor RUST FREE POWDER of DUROSTICK. After completion, seal the holes with D-55, DUROFIX or SUPER FAST of DUROSTICK. Next, clean all surfaces from loose materials, oils and saltsusing the biodegradable industrial cleaner BIOCLEAN of DUROSTICK.

Application: Empty the container with the acrylic emulsion (B 'component) in the packaging bucket and add slowly, while mixing continuously, the cement mortar (A' component). It is recommended to use a low rpm electric mixer with the appropriate mortar mixing attachment. The mixture remains workable for about 2 hours. HYDROSTOP WATERTANK must be applied on soaked surfaces.

Apply with an emulsion brush or roller in 3 crossed coats,with thickness of 1mm each one. The new coat will be applied when the previous becomespassable. If the coat is allowed to dry, soak the surface again. The material should not be applied at temperatures below + 5°C or when there is a likelihood of rain in the next 6 hours.

NOTES

  • For potable water is essential to observe the hygiene rules (chlorination of water, avoidance of contact with insects, etc.)
  • If you need better workability of the mixture, the first coat can be diluted 5% to 10% with clean, fresh water.
  • The tank should be used after a period of at least seven days from the application date of the sealant, without any health risks.
  • Before filling, the water tank must be rinsed thoroughly with plenty of water.
  • After curing, the product is harmless to health.

CAUTION

In order to complete a problem-free waterproofing seal in water tanks, create – using HYDROSTOP WATERTANK - a concaved curb on all the internal corners of the tank, embedding in the curb, the fiberglass mesh, DS-490 of DUROSTICK (cut strips 20cm wide) between the second and third layer of the sealer.

CLEANING

Clean all tools with water immediately after use.
