Aquagard concrete sealant

The system consists of
  • AQUAGARD primer (Curaflex® 1710/1711) Primer for AQUAGARD special paint
    The primer penetrates deep into the capillaries and air bubbles in the concrete, and closes these off so that they are permanently waterproof. This means that water cannot permeate around the gasket insert. The primer is applied using a brush or roller.
  • AQUAGARD special paint (Curaflex® 1715/1716) Special paint for sealing off core drillings
    Aquaguard special paint seals off the surface of the core drilling walls and simultaneously protects any possibly cut reinforcing steel against corrosion. The special paint is also applied with a brush or roller.

Aquagard concrete sealantConcrete needs protection!

Without protection concrete will permit moisture penetration to some depth before it becomes an absolute barrier – that is how moisture circumvents the gasket.

The product

Aquagard comprises a colourless base primer and a concrete-grey special paint top coat having a coverage of 3.5 – 4 m² per litre; both products can be brush or roller applied. The primer requires about 1 hour ventilation time at room temperature and the top coat will be touch dry within two hours at room temperature and fully cured within five to six hours.

Packings (1775)

Packings (1775)Curaflex® packings (for thin or hard membranes) (1775).

Packings consist of 2 no. 3 mm thick EPDM cutouts which are matched to the dimensions and hole diameters of the selected fixed/loose flange structures.


In accordance with DIN 18195-9, single-layer, loosely-laid tanking membranes must be edged using permanently compatible packings on both sides. Sealtightness is only guaranteed for fixed and loose flange structures if the thickness and the elasticity of the tanking membranes or also the packings is sufficient that they are pressed against the substrate to form a seal. Before laying ceiling sheets, the information provided by the sheeting manufacture must be observed in addition to the specifications in the standard (laying guidelines)!

A) Application with very thin or hard sealing sheets – Curaflex® 1775

If tanking membranes are made of very thin and/or very hard materials, even pressing onto the substrate is often insufficient. When such tanking membranes are used, the standard proposes the use of packings.

DOYMA packings are made of material-compatible EPD elastomer and have already been provided with the necessary boltholes on the fixed flange, and are therefore ready for installation. These matching packings are not included in delivery as standard.

B) Application with other sealing sheets

In the case of tanking membranes made, for example, of bitumen or bitumen rubber, even pressing onto the substrate is provided in most cases. In such cases, there are no problems with regard to sealtightness. For this reason, packings are not necessary.

Access reset for bituminous coating

Accessory set for bituminous coating consisting of space at rings, O-rings and fleece inserts. These parts match the dimensions and hole sizes for the selected fixed/loose flange structures when fitted together.


If steel pipe sleeves are built into building walls with bituminous coating, the contact surfaces must be sand-coated in the works. When ordering, please always state the following in such cases: “For bituminous coating”.

Application description

The contact areas / internal areas of fixed and loose flanges in the Curaflex® 5000, C/2/SD/5, F/2/SD/5 products and the Curaflex® 6000, 7000, 8000, C/2/SD/6 and F/2/SD/6 products will be sand-coated. WEROPOX-EP Primer no. 6142 with 6141- H hardener is used as a carrier material for the leading sand. Areas around drill holes or the bolts themselves, in locations where O-rings and U-washers will be applied, may not be sand-coated. Diameter of these surfaces: 40 mm for non-pressing water, 55 mm for pressing water

Sand coating is not necessary for Curaflex® 4005 and 4006 pipe sleeves.

Bitumen bituminous coating are to be applied in several layers according to the manufacturer’s instructions. Once the first layer has been applied the fleece insert, which is 100 mm larger than the fixed flange all round, is pressed into the first layer while still wet. After this, the fleece insert is trowelled in wet in wet so that the minimum dry layer thickness for the load case in question has been achieved.

Once the drying time stipulated by the manufacturer has expired, the bitumen filling compound will be broken out in the areas around threaded drill holes or bolts, for example using a hollow punch, depending on the version of the fixed or loose flange structure (Accessory Curaflex® hollow punch 1777/6 (5) or 1778/6 (5)). If Curaflex® products against pressing water are being used, spacer rings of 4 mm thickness are to be inserted between the flanges around each bolt, and in the case of Curaflex® products against non-pressing water the spacer rings are of 3 mm thickness. This prevents the overall bitumen filling compound being squeezed out when the loose flange is tightened, and also achieves a defined layer thickness of the bitumen filling compound between the fixed and the loose flange.

Furthermore, rubber O-rings are placed around the bolts and the spacer rings to prevent any possible pressure losses in the areas around the bolts.
