Method

We inspect the site in order to establish the cause of the cracking.  There may be may causes such as leaking pipes, storm water drains, soil type (clay, shale) etc. that may cause foundations to subside or move, resulting in the cracking of the building.  We work closely with a Geotechnologist/Structural Engineer whose services may be utilised in certain circumstances. 

Based upon our findings, we will give recommendations for the underpinning ie. number and location of pins.   In some cases sub-soil drainage may need to be installed and/or storm water may need to be properly managed in addition to the underpinning.  Stitching may also be recommended.

Underpinning

When underpinning, we dig and expose the foundations at the location that the pins are to be installed. We then dig approximately 1.5m below the foundation in order to install a 165mm x 3mm round steel casing underneath the foundation. Using a specialised hydraulic jack, we jack pile the steel casings down until they come to hard resistance or solid rock, welding them together along the way.

The soil is then removed from the steel casings and a reinforced steel cage is installed inside. A concrete mix of 30mpa is then poured into the steel casing. Finally, a concrete plinth is installed between the top of the steel casing and the existing foundation. The surrounding soil is then replaced and compacted.

Based upon our findings, we will give recommendations for the underpinning ie. number and location of pins.   In some cases sub-soil drainage may need to be installed and/or storm water may need to be properly managed in addition to the underpinning.  Stitching may also be recommended.

Where sub-soil drainage is required, trenches need to be dug below the foundations. Bidem cloth is installed into the trenches with agricultural pipe and 19mm blue stone around the pipe.

Sub-Soil Drainage

Where sub-soil drainage is required, trenches need to be dug below the foundations. Bidem cloth is installed into the trenches with agricultural pipe and 19mm blue stone around the pipe.

Stitching

Where stitching is required, a horizontal cut is made into the brick and mortar. We install a 6mm steel bar with concrete epoxy. The wall is then patched.
