Pilekon Construction

Our Solutions

We can pile 200 dia and 300 dia Auger piles as well as the conventional Jack Pile which sits underneath the foundation. We als have piles that are driving by a pneumatic mole.

In clay/shale type materials, the piles will reach refusal at around 35 to 50 SPTn values depending on the depth of the pile.

In Berea red soils we generally reach sufficient friction at around 6m-8m deep. We have carried out tests and comply with the SABS 1200F requirements. A modified Hiley formula also works for us.

Should higher loadings be required, the piles can be very effectively clustered to give the required strength.

Our underpin piles have a cantilevered pile cap design which connects the pile to the underside of the foundation. Foundations can be jacked; however we don’t encourage this (as is often results in unnecessary damage to the rest of the structure?).

The system is ideally suited to confined spaces as we can work with as low as 2.2m of head room and the equipment can be carried through a normal doorway.

Our piles do have some limitations and are not suited to all ground conditions. However, through innovation and adaptation of our systems, we are nearly always able to provide a solution that will meet specific requirements.”)

Should you have specific questions please contact us.

We also do mass concrete underpinning and box style foundation strength enhancers.
