VOID-TEK: Advanced Ground Heave Protection

Addressing the problems
caused by ground heave

SAVES TIME, SPACE AND COST

Ground heave.
A major problem when building on clay

THE PROBLEM

Ground heave is the upward movement of the ground surface caused by the expansion of clay soils when they absorb water.
It can damage structures and infrastructure if not properly managed.

THE CONVENTIONAL SOLUTION

Conventional solutions often include the introduction of a polystyrene cellular structure or void former. These are placed
beneath the foundation, creating a void that allows for the upward movement of the ground without affecting the structure
above.

But clay isn’t the only upheaval on site… polystyrene is!

EXCESSIVE DIG

Oversized polystyrene void former due to the inability to compress sufficiently.

BULKY

Leading to excessive transport,
handling and storage costs.

EASY TO DAMAGE + EXCESSIVE WASTE

Approximately 10% wastage and expensive disposal costs.

HAZARDOUS - BAD FOR THE ENVIRONMENT

Due to its molecular breakdown and static nature.

Introducing Void-Tek technology

Premcrete’s VOID-TEK is an advanced ground heave protection system that safeguards structures from soil expansion and contraction. Its flat-packed design simplifies transportation, handling, and installation, making it ideal for projects of all sizes. Despite its lightweight form, VOID-TEK offers exceptional strength and durability, ensuring long-term reliability under extreme ground movement. By absorbing and mitigating heave pressures, it reduces the risk of structural damage and extends foundation longevity. Suitable for residential, commercial, and infrastructure applications, VOID-TEK provides a smart, effective solution for ground movement challenges.

REDUCES DIG

Saving labour & muck away costs

FLAT-PACKED ON ARRIVAL

Vast reduction in transport costs and less space needed for storage

DEPLOYS IN SECONDS

Quick to assemble, less breakage and easy to cut with no mess

POLYSTYRENE FREE

Made from polypropylene fluted board, eliminating flaking – better for the environment

Revolutionary strength & flexibility

RIGID CONSTRUCTION

VOID-TEK is made entirely from Polypropylene fluted board which has high strength and durability. In contrast, conventional heave protection systems that are constructed with a polystyrene core are easily damaged and are liable to break and crumble, reducing performance, increasing an already unpredictable wastage allowance and ultimately cost.

STANDS UP TO THE TEST

The high strength and durability of the VOID-TEK flat-packed design, minimises damage wastage.

Even when deployed into position, it is very difficult to damage under foot. When minimal waste is generated, there are no messy polystyrene chips to dispose of unpredictable wastage allowance and ultimately cost.
