Settlement Joint Waterproofing System

Triflex ProJoint®

Advantages at a glance

Waterproof down to the smallest detailMade of fleece-reinforced liquid-applied waterproofing, the settlement joint waterproofing system Triflex ProJoint forms a homogeneous surface. The friction-locked bond between the waterproofing and the substrate prevents rainwater infiltration.

Flexible useTriflex ProJoint allows even complex structural joints, height differences and different joint widths to be seamlessly and reliably waterproofed with a simple system. The system requires a set-up height of only approx. 6 millimetres, which can be milled into the concrete substrate.

Applications

Long-lasting protectionWith Triflex ProJoint, the maintenance joint – reinforced by a metal profile – has high mechanical strength and is abrasion-resistant. It extends refurbishment intervals by years.

Certified safetyThe quality of the waterproofing component is certified by a test report. The waterproofing is root- and rhizome-resistant in line with FLL specifications. It is function-tested (dynamic loading at -20 °C to +50 °C) by an external test institute.

Flexible solution for joints

Liquid-applied joint waterproofing is flexible and moulds to the contours of the joint. Thus, not only straight joints, but also difficult constructions, can be reliably and seamlessly waterproofed. Even height differences can be surmounted. Different joint widths can be waterproofed with the same system.

The thin set-up of the liquid-applied waterproofing facilitates a smooth transition from joint to surface with minimal milling of the substrate. Rainwater cannot seep in, as the material adheres to the entire surface. Nor can roots and rhizomes penetrate into the normally sensitive interfaces.

Top decks and parking decks are often large areas which are subject to severe loads and stresses. Settlement joints absorb the movements from subsidence, expansion and shifting caused by dynamic live loads. Only when these joints too are reliably sealed is the parking deck’s waterproofing or coating able to provide secure protection for the concrete substrate.

Triflex ProJoint, made of fleece-reinforced liquid-applied waterproofing, is a joint-spanning waterproofing system which is reinforced with an edge protector. Settlement joints and surfaces can be waterproofed with the same resin. There is no need to change materials.

For nearly 40 years, Triflex has been offering tailored systems for multi-storey car parks and underground car parks. Property references throughout Europe demonstrate the quality of our solutions. Triflex liquid-applied waterproofing offers reliable protection against all external influences and provides a long-lasting seal.

System components

Substrate suitability should always be checked on a case-by-case basis. The substrate must be clean, dry and free of cement bloom, dust, oil, grease and other adhesion-reducing dirt. The substrate must be pre-treated in accordance with the specifications in the Repair Guideline (Rili SIB). The following volume specifications relate to a roughness depth of RT = 0.5 mm.

Moisture: When carrying out the work, the substrate moisture must not exceed 6 % by weight.Ensure that structural measures are taken to prevent moisture penetration of the coating from underneath.Dew point: During application, the surface temperature must be at least 3 °C above the dew point temperature. Below this temperature, a separating film of moisture can form on the surface.Hardness: Mineral substrates must be permitted to fully harden for at least 28 days.Adhesion: The following minimum tensile adhesion strengths must be met on pre-treated test areas: Concrete: in the centre, at least 1.5 N/mm², individual value not less than 1.0 N/mm².

If joints are waterproofed in combination with Triflex waterproofing or coating systems, the joints must be waterproofed first. The fleece width of 35 cm stated here must be increased to 52.5 cm, to ensure a junction of at least 10 cm to the subsequent Triflex system. To prevent abutting edges, joints should always be embedded in the substrate (see system drawings).

1. Triflex Cryl Paste Apply a width of approx. 4 cm to both sides of the joint to bond the Triflex Support Strip.

2. Triflex Support Strip Lay in the joint as a loop. Can be recoated after approx. 1 hr.

The subsequent application is wet-on-wet.3. Triflex ProDetail

Apply to both sides of the joint and on the support strip using a radiator roller. Volume: at least 0.70 kg/m.

4. Triflex Special Fleece Lay a 35 cm wide strip as the first loop, making sure there are no air bubbles. Overlap the ends of the fleece by at least 5 cm.

5. Triflex ProDetail Apply to completely saturate the Triflex Special Fleece and as a preliminary layer for the next fleece loop. Volume: at least 0.70 kg/m.

6. Triflex Special Fleece Lay a 35 cm wide strip as the second loop, making sure that there are no air bubbles. Overlap the ends of the fleece by at least 5 cm.

7. Triflex ProDetail Apply until the Triflex Special Fleece is fully saturated. Volume: at least 0.70 kg/m.

Total volume of Triflex ProDetail: at least 2.10 kg/m.Can be recoated after approx. 1 hr.For dimensions, see Triflex ProJoint system drawings.

Important note:Joints can also be waterproofed with Triflex ProPark.

Joint waterproofing

To protect the joint waterproofing, stainless steel brackets are attached to both sides of the joint edge.

1. Triflex Cleaner Degrease stainless steel brackets and roughen the underside.*

2. Triflex Cryl Paste Apply to the entire underside to bond the stainless steel bracket.

3. Edge protector Attach to both sides of the joint edge and remove excess paste. At least 3 mm must be left at the profile ends. Can be recoated after approx. 1 hr.

4. High-performance anchors The stainless steel brackets are predrilled. Drill dowel holes and vacuum up drilling dust.

5. Triflex Pox Primer 116 Fill the dowel holes with Triflex Pox Primer 116+ up to approx. 1 cm below the top edge of the joint protector. Insert high-performance anchors and screw these in. Remove surplus material.

6. PE round sealing band Place in the joint

7. Triflex FlexFiller Fill the joint so it is flush with the surface. Volume: at least 1.40 kg/m² per mm layer thickness. Ready for vehicle traffic after approx. 3 hrs.

Important note:The settlement joints are all maintenance joints. For visual reasons, it may be necessary to renew the joint ingress protection after structural movement.

All Triflex products are manufactured in accordance with the standards defined in ISO 9001. To ensure quality is not compromised, Triflex products are only installed by specialist, fully trained and qualified contractors.

When carrying out the work, always ensure compliance with the permissible tolerances for building construction (DIN 18202, Table 3, line 4).

Read the safety data sheets before using the products.

The specified volumes apply only to smooth, even substrates with a maximum roughness depth of RT = 0.5 mm. Special allowances must be made for unevenness, roughness and porosity. Information regarding airing and waiting times applies to a substrate at an ambient temperature of +20 °C.

Driving lane coatings are subject to constant loads and stresses in accordance with the level of use. The effects of UV light and weather as well as organic dyes (e.g. foliage) and various chemicals (e.g. disinfectants, acids, etc.) may cause discolouration, yellowing and chalking effects in finishes. Abrasion can scratch the surface. This does not affect the mechanical properties of the cured coating.

The basis for the use of Triflex products can be found in the system descriptions, system drawings and product information sheets. It is essential to heed these when planning and carrying out the building project. Departures from the technical information of Triflex GmbH & Co. KG applicable at the time of work can compromise the guarantee. Any project-related departures are subject to the written authorisation of Triflex. All data is based on general regulations, directives and other technical rules. The general regulations applicable in the particular country of use must be respected. Since the parameters can vary from case to case, the user is required to test the suitability, e.g. of the substrate.Non-Triflex products must not be used with Triflex systems. Subject to change in the interests of technical advancement or enhancement of Triflex products.
