KING Shotcrete Solutions
A Full-Service Solution for Your Shotcrete Needs
required to elevate the company from being just a supplier
to a technical resource. The KSS Technical Team boasts a
staff of more than 20 people—more than 10 of which are
licensed professional engineers and have a strong
understanding of shotcrete materials and equipment.
Understanding the intricacies of shotcrete mixture design
allows KSS engineers to explain how variations in mixture
design affect the plastic and hardened properties of shotcrete.
Then, they can respond immediately when jobsite concerns
arise. A strong knowledge of shotcrete equipment operation
allows KING representatives to educate crews, troubleshoot
shotcrete equipment issues, and recommend the most
suitable equipment for wet- or dry-mix shotcrete operations.
KING’s commitment to research and development (R&D) has
allowed the company to continuously improve the quality,
consistency, and performance of its shotcrete mixtures. This
commitment has resulted in several new products, including
the RS line of rapid setting/rapid strength gain, shotcrete
mixtures that provide numerous benefits, each of which
depends on the shotcrete application.
KING RS-D2 Shotcrete provides the compressive
strength values 2 to 3 hours after shooting that traditional
accelerated shotcrete mixtures achieve after 3 days. The
impact on the drill/blast/muck/shotcrete cycle is significant,
as are the available cost-savings. Ground control engineers
at one Northern Ontario mine specified an 8 to 10 hour
waiting period after the application of shotcrete, before
production miners could enter a heading to load the next
round. After a successful trial of KING RS-D2, the miners
were able to re-enter the heading only 3 hours after the
application. This resulted in the mine increasing
by more than one full round per week, which
added significantly to the mine’s production quota.
Another significant impact of KING’s R&D commitment
is the development and improvement of MS-W1 Shotcrete.
In 2016, a research project designed to improve the dry- to
wet-mix shotcrete process was undertaken. Its mandate was
to develop a “wet-mix shotcrete on-demand” solution that
would allow contractors to produce their own consistent,
pumpable wet-mix shotcrete when they need it, without
having to rely on availability of concrete from external, ready
mixed suppliers. Partnering with a powdered-admixture
supplier, KING’s research engineers developed a prepackaged
shotcrete material, which could be mixed on site and
would only require the addition of water and accelerator.
For over 30 years, the North American shotcrete industry
has recognized the name KING as synonymous
with quality and service. This reputation has been
earned through years of manufacturing and supplying quality
shotcrete mixtures on projects including concrete repair,
tunneling, and in underground mines throughout the United
States and Canada. Behind every bag of KING Shotcrete,
stands a team of respected industry experts who understand
shotcrete materials and the shotcrete process itself.
THE KSS TECHNICAL TEAM
Founded in 1986 with a small staff and one production plant,
KING Shotcrete Solutions (KSS) is now a leader in the supply
of shotcrete equipment and materials across North America.
KING’s strategy is to invest in the people and technology
Fig. 1: KING’s prepackaged shotcrete material is available in small
bags weighing 66 lb (30 kg) or bulk bags weighing up to 3300 lb
(1500 kg) that are marine-grade and water-resistant, allowing
long-distance transportation in harsh climatic conditions
Fig. 2: KING RS-D2 UG is a rapid-hardening shotcrete material
for dry-process applications. It greatly enhances shooting
characteristics, providing reduced setting times and rapid
strength development. This product is ideal for use in groundsupport
applications for mining, tunneling, and other
