Permeation Grouting

A Non-Disruptive Alternative To Traditional Underpinning in Sandy Soils

Stabilising granular soil prior to planned excavation and increasing the bearing capacity of the treated zone

In parts of Australia, buildings are often constructed on sandy, weak and poorly compacted, non-cohesive, granular soils. Depending on the application requirement, these sub surface conditions can be treated to achieve desired results.

It fills the voids between the soils and bonds the particles together. This creates a solidified mass that can support increased load, stabilise sunken structures and create temporary shoring solutions.

Permeation Grouting is a quick, cost-effective and time-efficient alternative to disruptive and labour-intensive solutions such as piling and traditional underpinning. The process leaves a clean and undisturbed site.

Safer Excavation Work

Permeation grouting minimises the risk to neighbouring properties movement due to undermining of the subsurface conditions’ structures, footings or vibrations.

Similarly, when adding in a new in-ground structure like a swimming pool, car park or basement, the surrounding soils must be stablised prior to any planned excavation works.

Permeation Grouting strengthens and stabilises the soil. It ensures the excavation process is safe and does not impact any neighbouring structures

Increased Structural Load Bearing Capacity

In situations where there is planned construction to modify a structure, such as adding another level or extension, an engineer may specify an improvement to the load-bearing capacity of the foundations.

Permeation grouting significantly improves ground conditions beneath the footings, that provides permanent load-bearing results that continue to improve over time.

Ground Improvement To Strop Structural Settlement

Over time, structures can move, settle and crack.

This maybe due to the initial poor compaction of sandy soils before construction, neighbouring excavations or water ingress below the foundations.

Permeation grouting is a non-invasive technology, that decreases the permeability of sandy soil.

Permeation Grouting bonds the sand particles together and creates a grout mass that stops further settlement of a structure and improves the bearing capacity.

Unique Features of Permeation Grouting

Ground Improvement

Permeation Grouting results in ground improvement beneath existing structures.

Minimally Invasive & Non-Disruptive Process

Permeation grouting can be carried out with limited access and is non-disruptive compared to traditional methods.

Quick and Efficient

Permeation grouting provides a fast solution, minimising downtime and business interruption.

Works In Non-Cohesive Foundations

Permeation Grouting works in sandy and non-cohesive foundations.
