    PR-Detail Pararapide RBM Liquid Detailing System

    The PR-DETAIL Pararapide RBM Liquid Detailing System is part of the Langley Pararapide range of resin-based, cold-applied liquid waterproo?ng systems. Pararapide is a fully reinforced, two-component, high-performance PMMA (polymethyl methacrylate) system with a catalytic action ensuring a fast and controlled curing time even at very low temperatures. The wet-on-wet application of components, each with cure times less than  30 minutes, makes this an ideal system for self-terminating details that require a  seamless connection to mineral faced RBM systems. The system carries an independently insured guarantee that coincides with the proposed guarantee duration of the primary waterproofing system.


    When to Specify
    This system is for projects where a flame-free and self-terminating detail system is required to provide a seamless finish to mineral faced RBM systems.

  • BIM

    Building Information Modelling (BIM), continues to transform the construction landscape in both the public and private sector by providing  digital representations of a managed physical asset.

    BIM is a process that enables documentation and detailed, structured information to be stored and maintained in a digital equivalent of a built asset. Instead of painstakingly re-keying information, for example, at handover of the asset, BIM digital information can be seamlessly transferred and used for maintenance and the ongoing evolution of that asset.

    BIM essentially holds all product information centrally and digitally for ease of retrieval and reference. It is a collaborative process involving the entire supply chain and is a way of working, managing information in a multi team environment, enabling everyone to understand a building through the use of a digital model.

    The digital model holds all the information needed to assist in the design, construct and maintain that building.
