Are you planning on installing a drainage system in your property in Cumbria? We, at Drainage Cumbria, understand that water is a critical resource, and proper drainage is essential for the safety and longevity of your property. In this article, we will share with you the step-by-step guide on how to lay drainage in Cumbria.
Before diving into the process of installing a drainage system, it is crucial to understand why it is necessary. A functional drainage system ensures that all water from rain, snowmelt or other water sources can be quickly moved away from your property. In the absence of proper drainage, water can stagnate in the soil and create various issues. It can weaken the foundation, lead to soil erosion, waterlogging, and can even make your home or commercial structure unsafe to inhabit.
To avoid such consequences, it is essential to invest in a proper drainage system. Our team at Drainage Cumbria can help you assess your property and determine the appropriate drainage system.
Now that we have established the need for a proper drainage system, let us focus on how to lay it in Cumbria. There are two types of drainage systems: surface drainage and underground drainage. The underground drainage system is the preferred choice in most situations as it is more efficient and aesthetically pleasing. Additionally, it has lower maintenance and repair costs compared to surface drainage.
In an underground drainage system, pipes are laid in a well-dug trench, the bottom of which is pitched to ensure that water flows towards the desired outlet. The pipes are surrounded by layers of fabric and crushed stones to prevent soil from entering and to support the pipes. Let us discuss the process in detail.
The depth of the trench depends on the severity of the drainage problem, the type of soil, and the depth of the water table. Generally, 18 to 24 inches is the minimum depth required for the trench. However, it is crucial to ensure that the trench is deep enough to accommodate the pipes and provide the desired slope for water flow.
Once you have determined the depth of the trench, mark the location using spray paint or other markers. It is crucial to ensure that the trench location is away from any utility lines, gas or electrical conduits, or other underground pipes. It is wise to contact your local utility company for guidance before beginning the digging process.
With the trench location marked, it is time to start digging. Excavate the trench to the desired depth and shape, ensuring that its sides are uniformly sloped. The trench's width depends on the size and number of pipes to be installed. A typical trench for a residential drainage system can be 12 to 16 inches wide.
Be sure to remove any rocks, roots, or debris from the bottom of the trench to facilitate a smooth flow of water.
The bottom of the trench needs to be pitched towards the outlet or drain to ensure the flow of water. The slope should be at least 1/8 inch per foot. A level or a string line can be used to determine the correct slope.
It is time to lay the drainage pipes! Before placing the pipes, wrap them in a layer of geotextile or drainage fabric. This will prevent soil from entering the pipes and clogging the system. Additionally, it helps distribute the weight of the soil evenly, protecting the pipes from damage.
The length of the pipes to be installed depends on the length of the trench. It is wise to add an extra foot of pipe length at each end to ensure that the system has room to expand and contract.
Place the pipes into the trench and ensure that they are laid with the perforated side facing downwards. Secure the pipes in place by adding crushed stones on either side of the pipe.
After the pipes are in place, add a layer of gravel or crushed stones on top of them. The gravel will protect the pipes from shifting, clogging, and will provide additional support.
After the layer of gravel installation, add another layer of geotextile or drainage fabric on top of it to prevent soil from entering the pipes.
Finally, cover the trench with soil, ensuring that the pipes are adequately buried, and the surface is level with the surrounding land.
Congratulations, you have successfully installed your drainage system! Now it's time to inspect and test the system to ensure that it is functioning correctly.
Run water into the system and check for any leaks, blockages or breakages. Inspect all pipes, joints, and fittings for signs of damage or defects.
Proper installation of a drainage system requires planning, knowledge, and the right tools. Hiring a professional company like Drainage Cumbria ensures you will have a system that can stand the test of time and prevent any issues related to waterlogging and erosion in your property.
