EXPANDO is the ideal alternative to noisy, risky concrete and rock breaking solutions like explosive blasting, jack hammering, concrete saws and stone cutters – particularly on sites with noise restrictions, vibration issues, safety risks, confined spaces or environmental pollution concerns.

EXPANDO is an environmentally friendly, safe solution that allows you to reduce labour and equipment breakage risks and costs, improve site logistics and minimise safety, noise, dust and toxic pollution of the site.

EXPANDO is safe, environmentally friendly, and a non-explosive rock splitting and concrete cutting solution.

is a cracking agent that comes in powder form, which when mixed with water expands. When poured into pre-drilled blast holes, it produces an extreme pressure of 18,000 PSI. After a few hours the tensile strength of the rock or concrete are overcome by the cracking agent. The rock or concrete then breaks following the pre- drilled hole pattern.

EXPANDO uses pressure to crack rocks and concrete, there is no explosion, thus EXPANDO is a non-explosive demolition solution. The product is environmentally friendly and is made from calcium oxide (quicklime).

Silent cracking agents are not a new concept they have been used in rock breaking since the 1950’s. Chemical rock splitting has been used extensively by drill and blast contractors as an explosive alternative for sites with vibration restrictions, rock fly problems or noise restrictions. EXPANDO can be used in an unlimited range of Expansive Mortar Applications.

Expansive mortar has been used successfully in mining and quarrying around the world for many years now. 

John quickly realised the opportunity to use non explosive expansive mortar as a demolition agent in other industries, after seeing it in use in Canada, where it is used extensively by miners as a cost-effective alternative to using dynamite to remove granite from the Canadian shield. 

The ever-increasing demand for non-intrusive, non-explosive demolition solutions, means Expando expansive mortar has vast potential to be used in a wide range of applications and industries in Australia.
