Methods we use locally

The right method depends on soil conditions, depth of failure, and access on site. The engineer's design decides, these are the options on the table for Newry properties.

Method Time on site Best for in Newry
Beam and base

Reinforced concrete beams that spread the load.

2 to 6 weeks Variable ground, bay windows, redistributing loads. Common on bay windows and settled extensions through Banbridge and Dromore where loads need redistributing along a single elevation.
Foam injection

Lightweight stabilisation that works to depth.

1 day for most jobs Slab re-levelling, void fill, conservatory bases. Useful for re-levelling slabs and floors in Dromore and Lurgan, where access for excavation is tight and disruption must be kept low.
Mass concrete

The traditional method, done properly.

2 to 6 weeks per elevation Shallow failures on traditional ground, insurance claims. Well-suited to traditional brick properties across Newry, Armagh and Downpatrick where shallow bays can reach competent ground by hand.
Mini piled

When the good ground is a long way down.

1 to 3 weeks on site Deep bearing layers, made-up ground, restricted access. The usual answer for deep clay or made-up ground around Newry and Lurgan, and for rear-only access through the property.
Resin injection

Targeted ground improvement, no excavation.

1 day for most jobs Granular soils, intact foundations, voids and density loss. Quick non-disruptive fix for shallow void filling and ground stabilisation across Newry / Down / Armagh, suited to lighter loads in Armagh and Banbridge.
Screw pile

Helical piles, no concrete cure time.

2 to 5 days Lighter loads, time-critical jobs, conservatories. Low-vibration option for terraces close to neighbours in Downpatrick and Portadown, with quick installation and minimal spoil.
