How to Prevent Waterlogged Construction Sites

Over the last few weeks, the UK has been hit every weekend with stormy weather. These storms bring heavy wind and rain and widespread flooding. With flood warnings are still littering the country. This type of weather can cause a lot of issues on construction sites. Not only does wind wreak havoc with plant machinery; but flooding can cause serious problems on construction sites, delaying the project.

If we get more rainfall than usual, there’s a chance that flooding could result in your construction site getting waterlogged. It’s therefore important you think about site drainage from the very start of the project. An experienced structural engineer should be able to assess a waterlogged area in order to check it’s feasibility for building on.

Why Waterlogged Ground is an Issue on Construction Sites

If your site gets waterlogged during periods of heavy rainfall, it might cause issues as you dig deeper into the ground. You may have trouble carrying out tasks such as laying foundations. This is because wet mud could collapse into areas that have already been dugout. Concrete also gets weaker if more water gets into the mixture. So waterlogged ground could become a problem when it comes to pouring concrete for foundations.

Waterlogged ground also makes it difficult to operate machinery such as diggers and dumpers, so it is vital to always make sure that the ground is safe to operate such machinery.

Constructing Temporary Drains & Deep Wells

This is usually the most cost-effective way of preventing the foundations of your construction site from being waterlogged. If you do this, you’ll then also need a mud pump to remove water out of drains and keep the site as dry as possible. This can be constructed with fairly simple tools and excavation and is popular with many small projects.

A similar solution for larger projects would be to construct deep wells. These can be used for when there’s a larger amount of water in the sub-soil that needs to be drained out. Again this needs to be pumped out continuously to remove the water in the ground you’re working on.

Marshy & Wet Soil Construction Sites

For construction sites that are already wet, such as marshlands or areas of wet soil; these sites might need more specialist techniques in order to drain the water out of the ground. This could be done by chemicals that freeze the water in the soil, or constructing sand drains.

As a plant hire company in the South East, we provide plant machinery for construction sites across the South East, including Sussex, Surrey, and South London. If you have a construction project that you need plant machinery such as Diggers, Dumpers, and Rollers, then we can help.
