DIN 18532-4:2025-06

This document applies to the planning, execution, and maintenance of waterproofing of concrete areas trafficable by vehicles with a waterproofing design in which the waterproofing layer consists of a single layer of synthetic or elastomer sheeting. This document contains all regulations required for this type of construction, unless they are already covered by the general regulations of DIN 18532-1. DIN 18532-4 is applicable in conjunction with DIN 18532-1. The waterproofing construction type regulated in this document is applicable to the following waterproofing construction types in accordance with DIN 18532-1: - construction type 1a: Waterproofing on structural concrete under a wear layer; - construction type 2a: Waterproofing on structural concrete under a thermal insulation layer; - construction method 2b: Waterproofing on the thermal insulation layer under a load distribution layer. This type of waterproofing is applicable for waterproofing trafficable areas of use classes N1-V to N3-V according to Table 3. It can be used to bridge cracks of crack class R1-V according to DIN 18532-1 that occur in the concrete substrate. This document has been prepared by Working Committee NA 005-02-96 AA "Abdichtungssysteme auf Beton für Brücken und andere Verkehrsflächen (SpA zu CEN/TC 254/WG 6)" "Waterproofing of concrete bridge decks and other trafficked (mirror committee to CEN/TC 254/WG 6)") at DIN Standards Committee Building and Civil Engineering (NABau).
