Wet Soils – Drainage Design For Pavement Foundations

Wet Soils – Drainage Design For Pavement Foundations

We all know what it’s like to have wet soil. The mud sticks to our shoes, the way the soil seems to suck the moisture right out of everything. Unless you’re one of the lucky people who live in an area with perpetually dry soil, you’ve probably had to deal with this issue.

We try to address wet soils by installing drainage systems. But how do you design a drainage system that will work well on pavement foundations? Let’s take a look.

What is a Drainage System?

A drainage system is a network of pipes and other structures used to remove excess water from an area. The procedure typically includes:

  • A catch basin.
  • A receptacle that collects water.
  • A series of pipes that carry the water away.

Drainage systems are often installed around buildings or in areas with a lot of foot traffic. The purpose of the system is to prevent water from pooling on the ground and causing problems like foundation damage, flooding, and slip-and-fall accidents.

How Does Drainage Design Work?

The first step in designing a drainage system is identifying the water source. Is it rainwater? Groundwater? Melted snow? Once you identify the water source, the next step is to determine how much water needs to be drained and how quickly it needs to be done.

This information will help the designer choose the suitable size pipes and catch basins for the job. The system must be able to handle the amount of water that is likely to come its way without being overwhelmed.

What Does a Drainage Plan Include?

The drainage plan will show the location of the catch basins and the connection of pipes. It will also show the direction in which the water will flow. The plan must consider elevation changes and potential obstacles to ensure that water flows smoothly through the system.

What Drainage Designs Are There?

Several drainage designs are used depending on the project’s needs. Some standard designs include:

French Drains – These are trenches filled with gravel and have a pipe running through the center. They are used to redirect water away from areas that might cause problems.

Catch Basins – These are structures placed in low-lying areas to collect water. They typically have a grate on top to keep debris and a pipe leading away from them to redirect the water.

Drainage Swales – These are shallow channels typically used to redirect water around obstacles. Drainage swales can be used with other methods to manage water effectively, such as catch basins.

Each design has its pros and cons to consider before deciding. A professional engineer will be able to help you choose the best method for your project.
