The Process Of Foundation Excavation In Layton
Excavation is the primary activity of a construction scheme. The process starts from the pits of the building foundations and continues up to the completion of the project. The process involves site clearance, setting out and safety excavation measures based on the depth of pit. Construction of small buildings can be done by use of manual tools such as spades and crow bars. Mechanical equipment will be required for large buildings. The following procedures are involved 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.
Set a groundwork layout for the construction work. A benchmark is established at the site by a masonry post and connected to the closest yardstick. Levels of the site are taken at 5-10m or 4-8 m intervals depending on the significance of the building and the terrain. Stretching strings are used to mark the centre lines of the walls across wooden pegs. It is important to set the right angle of perpendicular walls by marking their centre lines with tapes or theodolite.
Open planking method is used where the soils are loose and soft. After every excavation side, there are horizontal boards that are placed against each other. Vertical boards are used to support them. They must be marched to similar wood pieces on opposite side of the trench. The collapse of the trench would create great losses. Therefore one should carefully withdraw the pieces of timber to avoid such risks.
All groundwork constructions below the subsoil water level must be dewatered. This is because most constructions pose problems of waterlogging. Several operations such as laying bed concrete and construction of masonry posts should be carried out. Therefore, all works will be carried out effectively if the constructional area is dry.
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.
Cement concrete is used in building a masonry wall. A ratio of 1:4:8 of cement, sand and coarse aggregate is used. The coarse aggregate size must be of 40mm. However, lime concrete can also be used for this purpose. To ease your work, you can use mechanical concrete mixers. Concrete must be compacted and well laid in 15 layers.
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.
