EAD 030350-00-0402 Liquid Applied Roof Waterproofing Kits

According to the European Assessment Document (EAD) standard “EAD 030350-00-0402 Liquid applied roof waterproofing kits”, liquid applied roof waterproofing kits consist of a material or combination of materials applied to roofs, terraces or balconies, at least the main component of which is in liquid form. These kits may include components as defined by the manufacturer, for example:

• Supporting layer (a layer of material that forms the base of the assembled system).
• Parting layer (a layer of material applied between sections of a roof to provide protection against mechanical or chemical effects).
• Inner layer (fabric layer, non-woven mat made of synthetic material, fiberglass or other materials used).
• Reinforcement fibers.
• Fillers.
• The top coat (one or more layers of material applied over the assembled system, such as slate chips or a sunscreen coating). The top coat can have various functions, such as protecting the system from weathering or providing an aesthetic finish.
• Other liquid components such as primer and protective coating.
• If the kit is not bonded to the substrate, a ballast layer made of liquid-applied material, including fillers.

The mounted system (achieved by installing a liquid-applied roof waterproofing kit) may be fully, partially, or not at all bonded to the substrate.

Liquid-treated materials can be applied by pouring, brushing, spraying, or spreading. The process is specified in European Technical Assessments.

Common substrates for these kits include concrete, mortar, steel or other metals, waterproofing membranes (bitumen, PVC, TPO), and thermal insulation products. The type and substrate are specified in European Technical Assessments.

Liquid waterproof products under EAD 030350-00-0402 are based on the following:

• Polymer-modified bitumen emulsions and solutions applied in situ by brushing, spraying, or spreading, with or without a supporting layer, inner layer, or protective coating consisting of mineral granules, chips, or a solar reflective coating.
• Glass-reinforced flexible unsaturated polyester resins are applied in situ to specific wood-based substrates by manual spreading (e.g., manual placement). The inclusion of a pigmented fluid coating as an aesthetic and protective finish is assumed.
• Flexible unsaturated polyester or reactive poly(methyl) methacrylate (PMMA).
• Polymer-modified bitumen. Combined systems can be reinforced or unreinforced and can only be applied to concrete substrates; however, other substrates (e.g., metal, brick, wood-based) are permitted in detail. Combined systems are always suitable for inverted roof insulation systems, heavy protection, roof gardens or green roofs and therefore can only be used on roofs with a slope of 27 percent.
• Polyurethane, polyurea, and polyaspartic.
• Silane-modified polymers.
• Bitumen emulsions and solutions. These products are for use only in repair, renovation or maintenance purposes, or only in construction works with a limited service life of five years.
• Water-dispersible polymers.
• Thermoplastic block copolymer.

Polysiloxane-based products are covered by EAD 030019-00-04021 and its amendments. These liquid-applied roof waterproofing kits are not covered by a harmonized European standard.

It is the manufacturer's responsibility to take appropriate precautions regarding product packaging, transportation, storage, maintenance, replacement, and repair, and to advise its customers on the transportation, storage, maintenance, replacement, and repair of the product as deemed necessary.

The product is assumed to be assembled in accordance with: the manufacturer's instructions or (if such instructions are not available) the usual practices of construction professionals.

In the modern construction world, ensuring the longevity and safety of buildings, especially when it comes to weather resistance, is of paramount importance. Roofs, which serve as the primary barrier against rain, snow, and UV rays, require robust waterproofing solutions. This is where EAD 030350-00-0402, a guideline that sets standards for liquid-applied roof waterproofing kits across the European Union, comes into play. Developed under EU Construction Products Regulation (CPR) 305/2011, this document replaces the older ETAG 005 technical specification and provides manufacturers, engineers, and builders with a clear framework for performance, testing, and certification.

Continuing to play a key role in sustainable and resilient building practices, EAD 030350-00-0402 enables the use of innovative and environmentally friendly materials that comply with strict EU environmental standards.

This document outlines rigorous performance criteria to ensure waterproofing kits can withstand real-world conditions. Key elements include:

• Mechanical and physical properties:
• Waterproofing: The system must be resistant to water penetration under stagnant water conditions (e.g., hydrostatic pressure up to 100 kPa).
• Tensile strength and elongation: Tested according to EN 12311-1 standard, ensuring the membrane can flex without cracking during thermal expansion or building movement.
• Crack resistance: Includes flexibility and tear resistance tests at low temperatures (down to minus 20 degrees).
• Durability and environmental resistance:
• UV and weather resistance: Artificial aging according to EN 1297 standard controls deterioration by simulating exposure exceeding 10 years.
• Chemical resistance: Against alkalis, acids, and common roof contaminants such as bird droppings or other pollutants.
• Hail and impact resistance: Optional add-ons assess impact levels, which are critical for hail-prone areas.
• Fire performance: Classified according to EN 13501-5 standard for roof coverings, it offers Broof(t1) to Broof(t4) rating options that balance waterproofing with fire safety.
• Installation and application: Kits must include clear instructions for professional application, surface preparation, curing times, and multi-layer constructions. Sustainability elements such as low volatile organic compound (VOC) formulations and recyclability are encouraged to meet EU green deal targets. Compliance is verified by initial type testing by accredited bodies and ongoing factory production control.

In conclusion, EAD 030350-00-0402 stands out as a cornerstone of European construction innovation, guaranteeing reliable and high-performance protection for liquid-applied roof waterproofing kits. By standardizing quality and safety, it enables builders to construct sustainable structures that withstand the test of time and weather.
