Structural Underpinning Birmingham

Faster more efficient alternatives to traditional underpinning in Birmingham

There are an array of building that may require structural underpinning in Birmingham From the historically significant, to the modern commercial buildings, both have one thing in common, and that is that traditional underpinning methods are unsuitable. The busyness and congestion in Birmingham make traditional methods of underpinning impractical and in many cases infeasible. The fragility of the historically significant buildings of Birmingham make older methods of underpinning dangerous to the integrity of the structure. The disruption caused by excavation and heavy machinery means that business and property owners in Birmingham often suffer significant loss to revenue.

Resin Injection Technology offers a solution to underpinning that removes all of the hassle and disruption typically found with traditional underpinning, whilst providing a superior outcome. This makes Resin Injection Technology the best solution for underpinning work on domestic, commercial and historically significant buildings in Birmingham.

What is Underpinning?

Underpinning is a method of ground strengthening which involves the excavation and expansion of the foundations which support the load. Underpinning work is a major task which requires the use of heavy machinery and excavation. For properties in busy areas of Birmingham, ground strengthening can cause major disruption, however, Resin Injection Technology are able to apply a modern, non-invasive approach to underpinning that minimises disruption, and takes a fraction of the time.

For properties in Birmingham, underpinning may need to be carried out due to the following issues:

• Inadequate planning which fails to correctly identify the soil characteristics during the design

• A change in the soil conditions under the foundation

• The original foundation is no longer adequate due to ageing

• Repair work/excavation in a nearby area has endangered the current foundations

• Additional floors are being constructed underground

The issues listed above are not exclusive to properties in Birmingham, and Resin Injection Technology offer nationwide solutions to underpinning projects. However, the geography of Birmingham means that many of the issues listed above are often exacerbated by the array of historic architecture, as well as the large population and the busy road and rail networks. These factors often put strain on Birmingham’s infrastructure and can lead to foundational issues in buildings across the city.

Older Types of Underpinning VS Resin Injection

The most important factor that needs to be considered when any structural work is carried out is safety. It is imperative that any structural work done is carried out by experts and that the underpinning work done leaves the building in a safe and supported way. For business and property owners in Birmingham, convenience is also key when any structural work is done. Older methods of underpinning are not convenient as they often require excavation and the use of heavy machinery. Some of the older methods of underpinning include:

Mass Concrete Underpinning – The process of replacing the soil under foundations followed by concrete pouring. Typically used at shallow depths, box-shaped parts replace the soil in a pre-determined sequence.

Pilled Underpinning – A method of underpinning typically used at more substantial depths. During the underpinning process, steel cased piles that can be filled with concrete are installed. The piled foundations can be divided into three categories depending on the installation method, these are; driven piles, drilled piles and jacked piles.

Jet Grounding – A high velocity jet of cement grout is used in the creation of geometry of grouted soil. Jet grouting is typically used to create columns of grouted soil underneath an existing foundation. This method is effective across a variety of soil types. Jet grouting is also an effective method of underpinning as there is no need for load transfer structures. However, because jet grouting requires drilling and the use high-pressure, it is not always suitable for very sensitive foundations due to the soil disturbance caused.

These traditional underpinning methods are fast becoming a last resort for property owners in Birmingham. The use of resin injection is a far superior method, which does not require excavation, as well as taking a fraction of the time of traditional methods. There is also no need for occupants to leave the property whilst work is carried out. All of these factors are extremely important for business and property owners in Birmingham to consider when deciding which method of underpinning they will choose.

Resin Injection Solutions – Is a much faster and efficient method of underpinning used for soil stabilisation and the re-levelling of floors. Injections of resin materials made up of multi-component, expanding materials replace the need for heavily pressurised, hydraulic systems. By providing a much less disruptive and safer alternative to other methods of underpinning, resin injection shortens the completion time of work to a matter of days, without the need for any excavation.
