Not all types can be used to solve foundation problems. It is important to work with a company or individual to create a custom solution that meets your needs. Only once you’ve assessed what your foundations problem is should you start looking at what types of solutions there are to choose from. Common belief is that damp rectification work will become necessary in the near future. By then, it could be too late. How do you know if the chosen method of damp remediation is capable of providing a lasting solution?
The traditional method of damp-rectification involves an analysis and determination of the stability of the standing foundations. From here a firm is chosen who specialise in this type of method and will then design a footing plan for you to follow. A footing plan is essentially a map showing how your structure would look if it was built without additional support. The advantage of working this way is that the weaknesses of your existing footing can be seen clearly and any additional issues are easily identified. The foundation can then be strengthened to address any weaknesses that are identified.
One of the key benefits of the traditional method is the speed of development. Problems can often develop quickly, and the time it takes them to fix is shorter. As long as your building is structurally sound there will normally be no further issues until the full refurbishment is complete. The major drawback is that not all soils are suitable for bearing capacity projects and some have to be completely re-balanced. It is possible for soil density and movement to be so high that it can negate any gains made by strengthening the foundation.
Subsidence can be a more serious problem and can take many forms. A lot depends on the type of building and the site conditions. Poorly implemented subsidence programs can result in significant additional costs over the long-term. In addition, the increased costs could have been avoided by taking more careful planning with the original site conditions. Poor subsidence management and a poor subsidence problem have led to many buildings having to be moved.
Some buildings have no solid foundation and rely on steel bracing to keep them in place. You can reinforce a concrete slab or ground around a building, but this is not the best option if you have to deal older buildings or roads that have seen a lot of wear and tear. To strengthen the soil further the traditional methods use steel bracing systems. These tend to be big enough to withstand major shifts in the ground such as earthquakes and other natural disaster events but not strong enough to keep the foundations firmly in place.
There are many types and benefits to underpinning. Concrete is the most widely used foundation material because it is inexpensive and widely used in construction projects. Concrete is also the most effective material for strengthening foundations of new buildings. Concrete foundations can also be strengthened with the addition of grouting systems. These aren’t the only options to strengthen a foundation.
Another popular method to wet the foundation is seamless interlocking lappets. This system has the advantage of causing very little soil disturbance and allowing the pipes to remain in place throughout the entire project. This method of wetting structures can also save time and money, as the pipes can be re-used after they have been filled. The downside of using this option is that it tends to weaken the soil and this can negatively affect any future settlement efforts.
There are several other methods used to strengthen the foundations of buildings, but the ones mentioned above are the most common. It is a good idea for foundation problems to be addressed by an engineer or architect. Many engineering consultants can offer free estimates and conduct structural investigations on the property you are interested in. Based on their findings, they can advise you on the best solutions for your particular situation.
