Best Practices and Standards for High Performance Car Park Decking Systems

Introduction

This guide is based on the collective knowledge of FeRFA members having extensive experiencing in the required successful applications of car park decking systems. In separate sections, this guide gives recommendations for the selection, design, substrate preparation, application, maintenance and for the inspection and testing. its scope includes, Concrete, asphalt concrete conforming to EN 13108-4, hot rolled asphalt conforming to EN 13108-4.

Description

Reinforced concrete and steel framed multi-storey car parks often have reinforced concrete decks that are exposed to a wide range of aggressive influences. These decks need to have adequate protection to meet their service life requirements, safely maintain their function and provide a secure and attractive environment for visitors or residents.

Preventing water penetration in or through car park decks is of prime concern to owners, operators, and users. In addition to the potential damage and deterioration, water ingress can cause in the structure, water can create dangerous slippery conditions for pedestrians and drivers or leach soluble aggressive alkaline materials from the concrete and these can cause damage to vehicle paintwork.

Resin based car park decking and wearing systems are most commonly available in epoxy (EP), polyurethane (PUR) and acrylic (PMMA) types or hybrid blends which have some common characteristics as well as specific properties depending on their formulation. They are generally installed as thin multiple layer (1-6 mm) aggregate dressed coatings to offer protection, improved aesthetics and safety to reinforced concrete parking structures.
