The word permeable means a surface that allows water to pass through it. If a surface allows water or another liquid to pass through it, it is said to be permeable a paving may or may not be permeable. Most new pavings are permeable. As many as thirty to forty percent of all newly installed pavings are permeable. If a surface does not allow water or another liquid to pass through it, it is said to be impermeable. The term impermeable is the opposite of permeable. Permeable surfaces are often porous. The word porous means having lots of small holes. A pore is a small holes. Porous surfaces often have many small holes in them. A paving that has many holes in it will be porous.
A permeable paving has many benefits. The biggest benefit is that it allows the drainage of water and other such liquids. A permeable paving has many holes in it. The number of pores in a permeable paving can be anywhere from ten to fifteen thousand per square foot. This means that a ten to fifteen square feet tile might have as many as three to four million small pores in it. These pores are what make a paving permeable. They make it conducive to water absorption. This is what makes nice permeable paving so useful.
Most new cities have all their resin bound paving designed in a way that makes them permeable. This permeability is a very desirable feature in most pavings. This is because water not draining properly is a serious civil work issue. Having permeable pavings means that water will not accumulate on road and other places. This means that there will be little use for drains or other such equipment to be installed. If a paving is not permeable, it will need drains, holes manholes and other such equipment to enable the clearance of water. This is because impermeable pavings do not allow the absorption of water. Water, if left standing, on the roads and other such places can cause many problems. It can become a breeding ground for mosquitoes and other such insects that can cause diseases. This is why it is so important to make all public pavings in such a way that they are permeable.
There are many ways to make pavings permeable. One of the most common ways to do is is to use a material that can absorb eater. Example include sand and concrete. It is also possible to leave space between pavings so that the water can sleep through them. This makes the paving permeable and enable absorption through them. There are other ways to make pavings permeable as well. The more common methods have been discussed above. They are also much more cost efficient than other methods.
