Reactive Soil Control
Preventing foundation damage caused by expanding reactive clay soils beneath your home.
What Is Reactive Soil?
Reactive soil — particularly clay-based soil — expands significantly when it absorbs moisture. When this expansion occurs beneath your home's foundations, it creates immense upward pressure that can cause severe cracking and structural damage.
This process, known as "heave," can shift entire sections of a building's foundation, leading to cracked walls, misaligned doors and windows, and in severe cases, structural failure that requires expensive underpinning repairs.
The damage is often progressive. Small cracks gradually worsen with each wet season as the soil repeatedly expands and contracts, causing cumulative movement in the foundation.
What Reactive Soil Does to Homes
Expanding clay soil creates immense pressure beneath foundations, causing progressive structural damage.
Foundation Cracking
Expanding soil creates upward pressure that cracks foundations and walls
Structural Movement
Cumulative shifts cause doors, windows, and frames to misalign
Moisture Damage
Underground water seams feed the reactive clay, driving continuous expansion
Remove the Moisture, Stop the Damage
Rather than fighting the soil, we remove the moisture that causes it to expand — stopping the problem at its source.
1 Identify the Source
We locate the underground moisture seam feeding the reactive clay beneath your property, often coming from neighbouring properties or natural underground water flows.
2 Intercept the Water
The Hygro Seepage Control™ system is installed at the optimal location to intercept and redirect groundwater before it reaches the reactive soil under your foundations.
3 Dry the Foundation
As the system removes moisture, the reactive soil beneath your home begins to stabilise. Cracking stops and the structure is protected from further movement.
Ongoing Research & Development
We are actively engaged in R&D projects in both Australia and the USA, examining the behaviour of reactive clay soils and developing improved methods for managing ground moisture. Our commitment to research ensures our solutions remain at the forefront of seepage control technology.
