Guide to Drainage Solutions in Construction Sites
Construction sites are complex environments. A lot of planning and preparation is required before building gets underway. One issue faced early on with many construction projects is that of groundwater. Therefore, drainage solutions are essential.
Temporary drainage in a construction site ensures project timelines are not affected, and to guarantee site safety and adherence to Australian building regulations.
Let’s dive deeper into drainage solutions for construction sites, why they are so important, and the different types of drainage systems..
What Are Drainage Solutions for Construction Sites?
Construction site drainage is necessary to manage water runoff, to prevent soil erosion, and to maintain a safe work environment. The two main types of drainage on building sites are temporary and permanent drainage systems.
- A temporary drainage system for earthworks is designed to manage water runoff during construction in the short term. Various drainage systems prevent sediment from entering waterways, or redirect water away from work areas.
- Permanent drainage focuses on long term results, ensuring site stability and functionality. French drains are one example. These use perforated pipes to collect water and divert the flow away from structures and workers. Retention basins are employed to control water runoff by allowing sediment to settle. Culverts are used for stormwater management and are essential for correct drainage after construction is complete.
Temporary Drainage Systems for Earthworks
Temporary drainage solutions are critical during the early stages of earthworks on construction sites, as they manage the accumulation of water, guarantee safety, and also prevent delays in the work schedule.
- Drainage ditches are a solution that channels surface water away from active work zones. Acting as water diversions, these temporary channels are shallow and very quick to implement.
- Sandbags are a fast and versatile way to create barriers to control water flow. Sandbags also protect against flooding in specific areas of the building site.
- Geotextiles are used to stabilise soil and filter runoff. They also prevent sediment from entering city drainage systems. This is achieved by using erosion control mats and silt fences.
The above temporary drainage systems for earthworks are adaptable, efficient, and cost-effective solutions.
Why Are Drainage Solutions Essential in Construction?
A drainage system that’s well-planned is vital for the success of any construction project. They prevent water-related problems that can impact site stability, safety, and cause delays.
Flooding is a major concern on any building site. A flood halts progress, damages materials, is a safety concern, and may also increase construction costs.
When water flow is out of control, erosion results. Erosion destabilises the soil and can undermine structures. Another concern with erosion is the environment, as sediment may find its way into nearby waterways.
There are numerous benefits of having a well-planned drainage system. Not only does construction site drainage prevent flooding and erosion, but it also improves worker safety and the long term stability of the construction site.
How to Implement Drainage Solutions on Your Site
The first step is to perform a site assessment. Analyse the types of soil, the terrain, and any present water flow patterns that define potential problem areas.
The next step is to create a drainage plan specifically tailored to the needs of the construction site. Include measures such as sandbags, channels and ditches, and long term solutions like French drains.
Also, use silt fences to protect waterways, and regularly monitor and adjust the drainage systems as required.
When to Use Temporary Drainage on Construction Sites
Use temporary drainage during the early stages of earthworks, or during high or seasonal rainfall. Drainage is also effective when construction disrupts the natural flow of water, and to prevent delays, flooding, and erosion.
Choosing a Reliable Drainage Solutions Provider
When deciding on the right drainage provider, search for a company with experience in providing drainage and earthworks solutions for construction sites. You’ll also want a drainage contractor familiar with local Australian regulations and construction requirements.
