What is High Energy Impact Compaction?

High Energy Impact Compaction (HEIC) is a compaction technique that transmits rapid, high-energy impact in order to strengthen base materials and lay firm foundations for development.

HEIC can be far more efficient than conventional compaction methods – around a quarter of the cost, and 50% quicker than traditional methods. Our specialists can advise if HEIC is the right solution for your site.

What our 
clients say

“We’ve worked with Landpac on about 140 successful projects, for a wide variety of clients, in most Australian states and in New Zealand, China, Malaysia and Fiji. Working with them using HEIC, compaction can be achieved over a much wider range of soil moisture than can be achieved with conventional compaction, with a considerable cost saving.”

George Black, BLACK GEOTECHNICAL
“The Landpac team have been the solution to reducing the settlement risks on many uncontrolled and/or deep fill development sites I’ve advised on; their measuring and monitoring technology provides reliable data I need as a geotechnical advisor to better understand the ground and treatment outcomes achieved.”

"The Visy project was the second project I have worked with Matt and the Landpac crew on, at the Port of Brisbane. On both occasions, they have been fantastic to deal with and always willing to go above and beyond to help create the outcomes needed. I look forward to working with Matt and the Landpac team again in the future."

Understanding High Energy Impact Compaction (HEIC)

High Energy Impact Compaction (HEIC) revolutionizes ground improvement with its ability to achieve superior soil density and stability. Unlike traditional methods, HEIC uses advanced rollers and compaction technology to penetrate deeper soil layers, addressing heterogeneities and enhancing load-bearing capacity. Ideal for mining, dredging, and large-scale earthworks, HEIC reduces project timelines, lowers costs, and promotes sustainability. Discover how Landpac’s innovative solutions deliver efficient and environmentally responsible results for heavy-duty projects.
