Underpinning your house footings

Two major reasons for ensuring that your home is properly underpinned:

For your own enjoyment: having level floors and windows and doors that work properly and walls freed from cracks.

And when you come to sell, having your major asset in good order is esssential for an easy sale, in good time and for the best price.

Uretek is like keyhole surgery.

It's very quick: usually from half a day to two days at the most.

You don't need to move out. Very little, if any, furniture needs to be moved.

With Uretek underpinning there's no excavation, no mess inside or out. Gardens and paths are almost entirely undisturbed.

Uretek is the modern way to underpin and re-level your house footings

Uretek underpinning is the cutting edge, modern answer to the old-fashioned way to underpin: it is like keyhole surgery compared to concrete underpinning.

Uretek underpinning is not just for concrete slab floors. Uretek can underpin, raise and re-level strip footings, raft slabs and ‘Waffle-Pod' slabs, infill slabs and driveways. All are returned to correct levels rapidly with Uretek.

How to underpin your house footings with Uretek

The Uretek Method of underpinning footings is state-of-the-art, and like the best modern solutions, it’s SIMPLE: 1,2,3 !

  1. Unique, Uretek structural, expanding resin is injected into the ground beneath your home through tiny holes (either 6 or 16 mm diameter). 
  2. The Uretek resins expand, to fill any voids and compact any soft ground underpin the footings and then raise the home back to level.
  3. Enormous pressure can be exerted and it’s controlled by constant monitoring by laser level.

The results:

  • Wall cracks usually close up as Uretek lifts the foundation back to level. With brickwork then only some re-pointing of mortar joints may be required. With plaster or render walls only some fine patching and repainting may be needed.
  • Windows and doors usually work properly again because the building has been squared up.
  • Gaps between skirting boards and sunken floors also usually close up.

Uretek underpinning for your house footings offers you 9 major advantages over old-fashioned concrete underpinning:

  • There's minimal inconvenience to the household when Uretek is employed rather than concrete underpinning.
  • Most residential Uretek projects are completed in only a day or two, sometimes in just a few hours. This compares very favourably with concrete underpinning which typically takes many days if not weeks.
  • So with Uretek underpining there is no need to vacate the premises. Nor is there usually much furniture to move.
  • Concrete underpinning involves excavation and it’s very messy and dirty. But with Uretek there is no excavation and no weakening of support. There’s no water, no sand or cement dust, no mess.
  • There’s minimal, if any, disturbance to your pathways, lawns or gardens.
  • The uretek underpining resin injection is done through tiny, unobtrusive holes.
  • Wherever possible Uretek work is done from outside, to ensure the least disturbance to the household (using small tubes, just 16mm in diameter).
  • Inside the house injection can be done through even smaller tubes (only 6mm diameter), positioned to be quite unobtrusive, whatever the floor surface.
  • Unlike concrete underpinning, Uretek is not rigid and does not transfer the load directly to a different stratum of soil - which could cause differential movement between then unequally supported sections of the building, and, if that happens, much new cracking can occur.

As well as providing the modern answer to concrete underpinning, where required, weak foundation ground can be strengthened with Uretek Deep Injection.

Uretek warranty

Uretek materials injected below concrete have been specifically engineered to resist shrinkage or deterioration causing significant settlement, and as such are warranted by Uretek in strict accordance with the product durability requirements of the applicable Local, State or National Building Code.

Comparison of the different methods of underpinning your house footings

How do costs compare between Uretek & concrete underpinning?

If more than just one small corner of the house needs to be raised, Uretek is usually cheaper than concrete underpinning… and Uretek underpinning is much more convenient.

On the other hand, concrete underpinning can be cheaper than Uretek underpinning where only one small corner of the house needs to be relevelled. But concrete underpinning has some other problems, including the potential for cracks to develop in many new places in your home, if only one part is concrete underpinned.

It is always important to establish the cause of the problem and to take remedial action before correction. CSIRO publication, BTF18 "Foundation Maintenance & Footing Performance: A Homeowner's Guide" is a very informative guide.

N.B. Australian Standard, AS2870, re concrete underpinning warns, "Underpinning should generally be avoided where the problem is related to reactive clay," & "Deep underpinning should only be considered as a last resort"
