Drainage is the very essense of groudnwork, it is the simplest and purest form of gorundwork there could be. The goal of it being to redirect water to a specific place through a specific route by avoiding the things or places you do not want water to go through.

But why is it so important?

For example a building or any infrastructure project without effective drainage system, will face accelerated deterioration due to water damage over the years.

Which have down stream cost effects as more money will need to be spent on maintanace and repair if anything will be damaged. Also the structure along side the drainage will last longer and serve a lifetime!

Therefore drainage should never be overlooked, a lasting project is one that has a good drainage.

This article will teach you what drainages exist and which one you should use in what scenario, let's begin!

We are going to go through each one accordingly:

Surface Drainage

Subsurface Drainage

Grading & Sloping

Grading and sloping is the foundational technique of shaping the ground to create a gentle slope that directs surface water away from structures toward desired collection or discharge points.

It is most commonly used in almost every construction project from residential yards and building sites to roads and landscaping and especially during the initial site preparation phase.

Pros: Very cost-effective, requires no additional materials, allows natural water flow, and prevents ponding when done correctly.

Cons: Can be limited by site topography, may need periodic re-grading due to soil settlement, and is less effective in very flat areas or during heavy rainfall.
