Underpinning a Failed Foundation

In July, we were approached by Peter at Foundation Solutions Ireland whose client was building a Residential Log Cabin as an extension to an existing cottage. They were experiencing some issues with a previous extension and contacted Peter to see if he could help.

"The problem was an existing extension was sinking slowly causing structural cracks so they asked us for a possible solution with our foundation groundscrews. The site is old shallow bog with 1.2m of bog soil on 1m of normal sandy soil and then in to the harder subsoil where we hit a rock base."

Peter found us through our website and we helped devise the best solution. Groundscrews would not have been suitable as they could not be installed deep enough into the harder ground to ensure no further movement on the property.

Our underpinning solution is ideal for briefs like this as it causes minimal disruption and can often be hand installed which negates the need for an excavator. Subsiding properties are often due to insufficient foundations or shallow footings on ground conditions such as clay and, in this case, bog land.

"We contacted ABC Anchors who were able to supply us the machinery and large helix screw anchors. The support plates reached the required torque at between 2m-3m depth and the extension is now supported fully to prevent any further movement."

Screw piles have many benefits. If you are experiencing problems with a subsiding building where our underpinning solution may be suitable, or you have any other screw pile enquiries, please don't hesitate to get in contact with us.
