If you are thinking of embarking on a construction project, the first thing that should come to mind is the foundation. The option you decide to go with will highly determine the strength and durability of your building.
Among the most preferred and recommended types is a concrete foundation. It is characterized by strength, durability, and minimum maintenance requirements. However, you need to have the right piling contractors for the job to enjoy these perks. The right service providers will not rush to do the job. They will evaluate your needs and consider several factors when designing the foundation, some of which include;
Erecting a building in a waterlogged area isn’t always the right choice. It can cause many safety risks. If the water seeps into the foundation, it can become weaker or collapse in the worst-case scenario. That is why it is essential to inform your contractor if you have waterlogging concerns in your building area. They can confirm if it is safe to build in that area and whether they can rectify the issues using various methods such as layering stones.
The type of soil in the building area also plays an essential role in determining your foundation’s design. Areas with sand, gravel, and rocks or those with loam soil are considered foundation-friendly. Those with clay, silt, or peat may be challenging to work with because they tend to change their shift, causing cracks in the foundation, thus weakening it. Your contractor can, however, give you the best recommendation regarding such an area.
The level of soil erosion in the area designated for building your foundation is another factor that determines its design and structure. Water retention in a ground whose top layer has been eroded becomes difficult. It may, therefore, get dry or wet quickly, which could damage the foundation. However, the contractor can give you a suitable recommendation for designing a foundation on an eroded ground. The best way to go about such issues is through mini piling to improve the foundation’s strength, hence durability.
The water table
Most contractors are keen on the water table beneath the ground where your foundation is to be constructed. It should be low enough to allow for sufficient pressure on your foundation. A high water table may cause the foundation and overall structure to tilt and become unstable. It may create excessive settlements, thus reducing its effective pressure. A high water table can also cause the basement walls to lose their water-tight effectiveness and cause water to sip into the building.
The land in your building area may be corroded, especially if it is close to areas that were formerly sanitary landfills, industrial plants, our sewer outfall lines. In this case, contractors prefer to use concrete rather than metal in building your foundation. In scenarios where the compounds in the soil can destroy concrete, such as sulfate, they may prefer to use sulfate-resistant concrete.
The construction of the foundation can pose risks to nearby structures, especially if they very close. Activities that occur during construction, such as excavation, can cause their foundations to weaken. Foundation contractors are, therefore, keen on evaluating the structures of the adjoining or nearby buildings and give recommendations on the design that would best suit the scenario at hand.
If you have any concerns about the condition of the ground where you are about to erect your building, ensure that you contact your foundation contractor for recommendations on the most suitable foundation design.
