A Study On Surface Drainage

Allowing water to pool in any one place that isn't already a large body of water is asking for cause for the man-made structures in the region. Any change in the moisture level of the subsoil can cause the stability of the soil to shift, creating a ripple effect that can ultimately see skyscrapers toppled. While that pervasive threat is not one to be underestimated, it is also important to consider what large collections of water along the surface of our buildings and infrastructure can do. Today, we're going to investigate not only the risk surface water can present, but also the ways in which it can be mitigated.

The Mariana Trench, But 213 KMs Forward, And A Little To The Right
Where the ocean might seem like a near bottom-less pit that just absorbs all the water the planet might care to feed it, us mere land-dwellers will need to enact a number of drainage plans to make sure we don't end up swamped under more water than we know how to handle. In most urban environments, this will be achieved via rooftop rainwater drainage and drainage in paved areas

Keeping An Eye On The Skies
Roofs are perhaps one of the easiest places to keep water away from, since their relative height to the surface of the planet allows you to use gravity to perform the majority of the work while directing water. Typically, most roofs use a sloped surface to force surface water to run into a collection channel of some description, generally a gutter, that transports the water to the drainage system, normally by way of a vertical rainwater pipe. Most buildings have two drainage points installed along their roofs to provide a redundancy in the event that leaves or other debris cause one drainage point to become blocked.

Paving A Road With More Than Good Intentions
Wherever you have pavement, the question of drainage might seem to become more complicated. The pavement won't stop the water from pouring into the water table through the seams, and the large amount of surface water pooling above ground can prove a nuisance, if not an outright danger, to anyone travelling above ground.

Fortunately, yard gullies and channels provide more than enough drainage to mitigate these issues. The channels may be made of clay, cast iron, or concrete, and may or may not have a grating or cover along the top to avoid accidents, or it can be simply cut directly into the pavement itself, providing a shallow channel for water to run along.

Meet All Your Drainage Requirements With Ease
Proper drainage is not a requirement to take lightly, as a little bit of water can quickly leave your property or infrastructure entirely unusable. Thankfully, when you need to install drainage on your property, you can rely on Abi Civil to get the job done.
