Ground excavation is the preliminary step of a construction project. Excavation activities are involved from the beginning of a building project up to the end. The process includes safety building measures based on the depth of pits and site clearance. Different equipment is used depending on the size of the building. Manual tools such as crowbars and spades are used in the construction of small buildings, unlike the large buildings that require mechanical equipment. In a nutshell, the following information explains the basic procedure to follow in foundation excavation in Layton.
Materials such as tree stumps, vegetables and brushwood must be cleared from the construction site. All tree roots above 30cm from the foundation level should be uprooted. Uneven ground surfaces are not suitable for construction works. Spaces and pits left after the removal should be filled with soil to ensure that the surface is even.
A groundwork layout ought to be set. This is done by establishing a benchmark at the site and connecting it to the next yardstick. Depending on the land terrain and the significance of the building, you should take 5-10m or 4-8m interval site levels. Stretching strings can be used to mark the centre lines of the wall across wooden pegs. If you need to set the correct angle of a perpendicular wall, you can use theodolites or tapes to mark their center lines.
Open planking for soft and loose soils excavation should be done. Horizontal boards are placed against the excavation sides. They are anchored by vertical waling boards which are marched to similar wood pieces on the opposite side of the trench. After the completion of the groundwork, the timber pieces should be withdrawn carefully to avoid the collapse of the trench.
Dry surfaces provide a friendly environment to work in. It is important to dewater waterlogged surfaces to ease your job. Laying of concrete beds and building of masonry pillars will help to ensure dryness. At times, working on waterlogged surfaces may be a challenge. Clearing water from wet constructional surfaces will enhance the effectiveness of your project.
Maintain the water table to a level of 0.5m below the bottom of the excavation to improve dryness. Various approaches to lowering the water level can be used. Many online sites provide these methods. You should select a site with the information providing the most suitable and economical method of dewatering construction sites.
Masonry walls should be built using cement concrete or lime concrete. The concrete should have a mixture of cement, sand and coarse aggregate that should be mixed in the ratio of 1:4:8. The concrete should be placed well and compressed. Use of mechanical tools and machinery will help to ease your work. Furthermore, it will be save time and management cost.
Concrete need to be protected to avoid cracks. You can use wet gunny bags. It should be protected two hours after laying it. In addition, this should be followed by curing it for at least ten days. Three days after laying the concrete, the construction work can be continued.
