Weaknesses and Strengths of Masonry

Cement or concrete is one of the most common materials used for building patios. Cement patio designs offer various advantages: it's durable, versatile and relatively cheaper than other materials such as stone.Start creating your design by first determining what purpose your patio will serve. Patios are essentially outdoor extensions of rooms. So, if you want a patio that will serve as an extension of your living and dining areas, a 12 by 12 foot patio offers enough space for furniture as well as room to walk around in. If you want a patio that will visually connect your house to your garden, then you will have to incorporate more landscaping features into your patio design. Some great ideas include plant boxes, alcoves for shrubs and small trees, and maybe a trellis where you can grow flowering vines. The design ideas you can choose from are limitless. Some homeowners build patios that connect with other features in their yard such as a pool or a gazebo. You can also do this by creating a concrete path from the main patio to the said feature. If you already have an existing pool you can introduce a relaxing resort feel to your yard by creating a cement patio design that evokes the look and feel of resorts. Concrete is a versatile material and you can choose from different looks and add-ons to create the look that you want. A network of walkways will surely add to the beauty and functionality of your patio and yard. You can also add furniture such as umbrellas, rattan or wicker chairs, and lounges for that genuine resort ambience.When designing your cement patio, an important consideration is the size of your property. The patio should be proportionate to the size of your house and yard. A large patio can overwhelm a small house and will look out of place. Similarly, a small constricted patio will look awkward in an expansive yard. You should also check with your local building codes and zoning laws. Another important factor is of course, your budget. If you are working on a tight budget, then a cement patio design is the better choice for you. Concrete patios don't have to look grey and boring. You can always perk it up by using your creativity and usefulness. For example you can use blocks of wood, pieces of ceramic tiles, and even sea shells to accentuate the patio floor. Take a quick look at some online resources for patio design ideas and you can find a wide range of creative solutions for cement patio designs.
