Resin injection underpinning is a method of foundation repair. The injection process is simple – the solution is injected into the building or house foundations. Once the solution reaches the surrounding soil, it expands. This method compresses the existing soil while filling in any cracks and voids. 

It’s used to reinforce or repair foundations, underground tunnels and pipes. It fills in the gaps to make it watertight and stronger. There are different types of underpinning; concrete underpinning requires excavation and laying fresh concrete to stabilise a structure. The modern and more efficient method is chemical underpinning. Chemical underpinning utilises resin injections to address structural repair. 

It can be used to address a variety of foundation problems, including:

House Subsidence 

Unlevel buildings can be easily addressed with a resin injection. While subsidence is a common outcome in properties, weak soil or other issues can cause severe damage if subsidence continues. Your doors and windows are a good starting point – if there are widening gaps or you’re struggling to open and close doors and windows, you may have a big issue. 

Uneven floors 

An unlevel floor isn’t always the most obvious symptom of subsidence issues. If you notice the issue, it’s a strong indication that there are foundational issues to address. The most obvious sign of an uneven floor is visible across the other side of a room. 

Uneven floors can also contribute to misaligned windows and doors. A structural engineer can assess how big a problem the issue is. 

Cracking walls 

A crack isn’t always terrible news; many hairline cracks are superficial. Big cracks point to a larger issue and impact the bearing capacity of a home or property. Look for exterior cracks in the concrete slab, brickwork, and render. Interior cracks to be concerned about are in the floor tiles, walls, and plaster. If new cracks appear or the existing ones grow longer or wider you need professional assistance.

The resin injection is applied using pressure and fills all the holes and voids to address foundational repair. Resin injections can be used for house underpinning, commercial underpinning, and public buildings, fix subsidence and foundation issues, and handle crack repairs. 

When is resin injection underpinning the best solution? 

Whether you have cracked walls or sloping floors, a structural assessment can determine the serious issue and which underpinning solutions suit your situation. A reliable underpinning contractor, like R+R, will review the structural design and assess wall cracks, water leaks, windows and doors, jammed doors, rising dampness, tree roots, leaning walls, or a leaning house.

What are the most common foundation problems that can be addressed with resin injection underpinning? 

There are obvious issues that chemical underpinning can repair – from sinking floors, drives, and paths to jammed windows and doors and even wall crack repair. It’s an effective alternative to traditional underpinning and can address the most common foundation problems. 

There are several factors to consider before you decide on the best course of house levelling action. There are a variety of causes of weakening or unstable ground – it could be down to soil types, seismic activity, soil erosion due to flooding, excessive load, weak soil, poor workmanship or nearby excavation work. 

Traditionally, underpinning can be a dangerous choice in reactive clay soils. The Australian Standard for footings and concrete slabs is to avoid traditional underpinning methods when dealing with reactive clays or soils. Other forms of foundation repair include concrete or steel piles beneath the existing foundation, concrete piers in the case of sinking piers, and slab jacking or slab lifting in extreme cases.

When you contact us for resin injection underpinning in Melbourne, one of our team members will visit your property to conduct a thorough site investigation. This investigation aims to pinpoint the cause of subsidence, assess any associated cracking, and determine the necessary corrective steps.

We may also perform foundation soil testing and monitor moisture levels to understand the underlying issue affecting your Melbourne property.

Once we identify the cause, we’ll recommend the most suitable solution for rectification. To ensure our injection holes are clear of any service pipes or cables, we locate them. After the injection process, we use cement grout to fill the holes. 

The project’s duration typically ranges from a single day, depending on its size, and our team will provide you with a project timeline before commencing the work.
