Reducing The Risks of Flooding With Drainage

Flooding is becoming more and more of a prevalent problem with a predicted over 600,000 homes in 2022 facing the future risk of extensive flooding. It’s highly important when building new buildings or protecting current buildings to consider the role that drainage and other systems has to play to protect against flooding. This article discusses how you can reduce the risks of flooding with drainage solutions and using appropriate groundworks for new construction. The benefits are:


  • Reducing insurance premiums by actively taking steps against the damage that flooding can cause.

  • Ensuring that a property is protected if an area is at risk of flood. The risks are becoming worse in certain areas so this may mean that appropriate drainage needs to be put into place.

  • The relevant excavations need to be made in new projects in order to protect the property for the future. Groundworks companies such as our team can support at this stage and ensure that you can install the appropriate systems.

  • The way in which the foundations of the property or building are designed as well as other structural considerations during the preparation of construction can also have active roles in reducing the risk of flooding. An example of this would be reducing the ability for water to pool around the property.


At Wilsons Groundworks, we are the leading independent provider of groundworks in Bristol and the surrounding areas. We are able to provide the assistance that you need during your project for excavations, demolition and all of our other groundworks services. We will work with you to ensure that the relevant excavations are put in place to install drainage solutions and we can also advise on reducing the risks of flooding to the building.

What Increases the Risk of Flooding to Occur?


Flooding is unfortunately becoming more and more of a prevalent problem in the UK. Changing climate conditions lead to heavier rainfall and increase the frequency of rainfall. As historic systems were built in previous climate conditions – they may not be fit for purpose and are exposed to serious damage from extended heavy rainfall. Other risks are:


  • Natural defences such as riverbanks erode over time. With increased rainfall due to other factors – this makes these banks erode faster which can then lead to flooding to take place.

  • Urban developments and structures can cause the flooding process to occur or speed up. Trees have a large role to play in the prevention of flooding as they offer protection and water absorption. The removal of natural barriers can increase the risk of flood.

  • Dry, compacted or very wet saturated soils also increase flood risks. Rockslides and rockfalls can also cause rocks that do not allow water through to stack and form. This can be even more of a problem if these rocks give way and massively increase water flow.


Groundworks’ Role in Reducing Flood Risk


Groundworks are highly important in laying the correct foundations and trenches for drainage and other preventative measures against flooding. Taking preventative measures during the construction of a new building or if a current building is upgraded is key in protecting the building against the risks of flooding. Groundworks companies such as our team will work with you to prepare for the relevant installation of flooding protection. Flooding is becoming more and more of a problem for the UK with increased rainfall and damage to rivers.
