Sprayed concrete remains a leading support method for tunnel and underground mining, known for reducing material costs, its speed of application and, above all, the safe working environment it provides.
Used in several large-scale projects worldwide, such as the Gotthard Base Tunnel, the world’s longest railway tunnel, or the transition to underground production at Chuquicamata mine; the following list features some of the most relevant, free publications about shotcrete.
It includes manuals and technical presentations among others, in order to provide you with an all-encompassing look at shotcrete, the support method that continues to gain traction globally.

Revised in 2014, this guide published by the ICH (Instituto del Cemento y Hormigón de Chile – Chilean Concrete & Cement Institute) is authored by leading shotcrete experts including Sergio García Guzmán. It explains key topics from a practical point of view and presents them simply: whether you’re a novice or an expert, it should be very helpful.
Putzmeister and Sika collaborated to create this concise introduction to shotcrete and its applications. In the English version, revised in 2011, authors Jürgen Höfler, Jürg Schlumpf y Markus Jahn, offer an introduction to ingredients, applications, methods and processes. With a great deal of detail, it should be a go-to for any type of doubt related to shotcrete.
The UK’s Sprayed Concrete Association (ASA) brings a quick introduction to the world of shotcrete through their new guide. Published in 2016, it covers the key benefits of shotcrete as a construction material, as well as offering a handy comparison between the dry and wet-mix process.
EFNARC (Experts for Specialised Construction and Concrete Systems) develops guides and regulations about shotcrete in a bid to consolidate technical and professional standards. This 1999 guide runs through basics like ingredients, requirements for mix recipe and durability, the correct application method, test methods, quality controls and safety. In essence, it covers all the basics to ensure optimal results for your shotcrete.
This article from 2015 published in The Journal of the Southern Africa Institute of Mining and Metallurgy, reviews the use and control methodology for the correct application of shotcrete in underground mining.

This article from Mexico’s magazine Construcción Y Tecnología en Concreto (Construction & Technology in Concrete), describes the uses and applications of shotcrete in underground mining. Written by engineer Raul Bracamontes, it covers the current state of play as well as the evolution of this industry in Mexico.
The working group from France’s AFTES (Association Française des Tunnels et Espaces Souterrains – French Tunnels & Underground Space Association) co-wrote this paper, providing insight into shotcrete as a protective layer, as a structural layer and as a support ring. It describes each of the categories, alongside technical recommendations, requirements and mix design.
The AUSS (Australian Shotcrete Society), which promotes the use of shotcrete in the country, educates end users about its correct application. Last revised in 2010, it features recommended practice and technology descriptions for the different applications, while covering materials, recipe mix and specifications, and equipment.
