Recently I got the chance to attend Flowcrete UK’s CPD seminar ‘How to Avoid Screed Failure’, which was being presented by Flowcrete UK’s Managing Director Alan Dean.
Although I have worked in the resin flooring world for over 10 years (prior to Flowcrete I worked for one of our approved contractors) this educational tutorial still provided a wealth of insights into screeds and their make up, specification and installation.
During the 30 minutes of the CPD seminar Alan Dean expanded on the properties of different screed types and the methods used during their application. These points are illustrated with visual aids such as photographs, short video clips and infographics to help attendees understand the points and principles being outlined.
Types of Screeds
Generally speaking there are two types of screed, a semi-dry formula which is hand applied and then trowelled to a finish and a liquid, free-flowing mixture that is pumped to a prescribed depth.
Of these types there are several different identifiable screeds with different properties which will thrive or fail in various environments and which can be applied in varying thicknesses.
One particularly useful example that came up during the CPD was to see a comparison between a hand laid screed versus a machine laid screed and learning how this can affect the overall finish as well as the sort of failures that can occur if the installation is incorrectly undertaken.
Screed Specification Advice
The discussion on screed specification during the seminar has been designed to inform architects and specifiers on how to identify the best solution based on the properties of the screed and its suitability for their project’s budget, schedule, development constraints and on-site conditions.
One of the discussions I found particularly eye-opening was on green screeds, as I was surprised to learn that Pulverised Fuel Ash (PFA), an industrial waste product, is disposed of in lagoons. Removing OPC from screeds and using PFA instead reduces CO2 emissions and minimises the amount of PFA sent to landfill.
The presentation was rounded off with a selection of project photographs to provide a broad reference list, with a short blurb on the screed used and the size of the installation.
Flowcrete UK’s How to Avoid Screed Failures CPD is a great training aid for architects and specifiers looking to increase their understanding of this often unseen, yet always crucial, element of the floor build up.
