The most preferred way to pave a driveway or walkway is to put in a concrete installation. Concrete is also the best way to create a durable, clean surfaced and easily maintainable portico or a deck. As the most frequently used man made material, concrete is resistant to wear and tear and is extremely durable. First used by the Romans, concrete is a compound that is mixed using cement, sand and aggregate which either consists of granite or limestone gravel. Easy to mould and therefore to give shape to, concrete once set will stand the test of time. So whether it is paving your driveway or installing a platform into your front or back yard, concrete is the best substance to go with.
Concrete installations are specialist in nature
Once you have decided on putting in a concrete installation, it would be wisest to call in a general contractor to handle the job. A contractor will first measure out the ground area and prepare the surface by removing a little of the top soil along with any plants and vegetation. Once this has been done, the contractor will place a layer of sand onto which the base of the concrete structure would be poured. When ready, a mould in the correct shape and predetermined dimension will be constructed, into which the concrete will be poured.
With all the ground work and preparation done, the general contractor will go ahead and mix the right amount of concrete as required for filling the mould. This is done by determining the correct proportions of cement, gravel and sand, and by mixing these with water. In today's day and age, the contractor may add appropriate chemical substances that will enhance the strength of the concrete and enable it to set faster. The concrete, once it is mixed, is poured in the correct manner so as not to allow any air packets to form within the mould. While solidifying, the concrete goes through a chemical process called hydration that binds the entire compound. A general contractor will always ensure that the structure is kept moist since the entire binding process requires water.
These steps are of a very precise nature and general contractors specialize in mixing and pouring concrete to create various installations. Many contractors spend years gaining experience and learning this skilled craft, so it is always advisable to call in a general contractor to carry out a concrete installation in the most effective and efficient manner.
Finding the right contractor to do your job
One of the primary concerns is finding the right general contractor. First off, ask all your friends and relatives in the area if they have had similar work carried out and to refer a contractor.

Based on each one's experience and the quotations received, narrow down the list to about three contractors. Call each reference these contractors provide you. Finally, settle with the contractor that has the best balance between experience and cost.
