Our piling systems are low vibration with zero spoil and are installed with lightweight rigs suitable for restricted access work. We have the pile for your job with loads from 50kN - 300kN capacity and offer a fast and friendly service. If you require any further information, please contact us as below.

Larsen Piling have been performing piling and underpinning works for over thirty years. Larsen Piling, together with CITB NI were the first in Northern Ireland to secure their NVQ in Piling. Larsen Piling are keen to promote professional and technical competence within their team and the wider subsidence remediation industry. Larsen Piling offer a comprehensive range of subsidence repair techniques and engineered foundation solutions.

Larsen undertake annual Health & Safety reviews together with rigorous quality and technical checks on their works to meet customer requirements.

LARSEN EXPERTISE
Over the last forty years, our experienced crews have installed tens of thousands of metres of piling to meet the needs of industrial or domestic clients.

MINI PILING

WHY MINI PILE?

Mini piling is a proven system to address foundation problems. For example:

• Unsuitable ground conditions for standard foundations
• Risk of undermining or damaging existing services and/or foundations
• Restricted access for piling equipment
• Minimise costs by reducing the depth of the hardcore base required for the mini piling rig
• Can operate in a low headroom situation
• Eliminates fumes in confined areas, if using an electric power pack
• A low vibration solution
• Minimal noise levels
• Upgrading foundations / floors for increased loadings - mini piles are a less expensive option
• No spoil created by use of mini piles
• Minimal disruption to the site or building

Underpinning & Structural Repair

We are the largest underpinning contractor in Ireland, responsible for stabilising structures ranging in size from the largest building ever underpinned in Ireland, through to the corner of a domestic garage.
We offer a full design & install underpinning package to NHBC, Homebond, Insurance companies, home owners and main contractors. With membership of ASUC (Association of Specialist Underpinning Contractors) we can provide 12 year insurance guarantees on our underpinning repairs.

In conjunction with our underpinning systems or for standalone crack repairs, we offer a full range of crack repair solutions.

Piled underpinning may be necessary for a variety of reasons.

SIMPLY SUPPORTED NEEDLES
This method supports the wall / foundations by installing piles at either side of an existing wall (internally & externally) or at either side of a corner (both piles externally).

A pocket is created either in the masonry above the foundation (if site dimensions allow) or beneath the foundation (if the depth from ground level to top of foundation is shallow – less than 400mm). A cage of structural steelwork is inserted through the pocket and placed over the piles. The needle is then cast in-situ using high strength concrete.

CANTILEVER NEEDLES
The construction of the cantilever needle beam is as per the simply supported needle beam. It varies however as both piles are installed either externally or internally (usually externally). The pile installed closest to the wall is a compression pile and the pile furthest away from the building is a tension pile.

SINGLE PILE NEEDLES
A single pile cantilever needle beam is a shorter version of the cantilever needle beam that relies on the tension capacity of one pile. It can be installed either internally or externally (usually externally) within a space of 750mm from the wall to be underpinned (including rig access).
