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.
Site clearance is the preliminary activity of construction. The site should be cleared of vegetation, stumps of trees and brushwood construction before the construction work is commenced. All tree roots should be removed to a minimum of 30cm below the groundwork level. All pits left after the removal of roots or caused by old groundwork should be filled up with soil and compressed.
A layout of the ground surface where the construction takes place is set. This is achieved by placing yardsticks at the site and connecting them to the next benchmark. However, different set ups are placed depending on the type of building and the land terrain. Interval levels of 5-10m or 4-8m must be taken. When marking center lines of walls, you can use stretching strings across wooden pegs. Setting up of perpendicular angled walls may be a challenge. You should consider using tapes to mark their center lines to achieve the right angle.
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 After the completion of the groundwork, the timber pieces should be withdrawn carefully to avoid the collapse of the trench.
Waterlogged surfaces are not suitable for construction works. They make masonry work to be stressful and a lot of time is wasted. All groundwork sites below the subsoil level should be dewatered. Operations such as laying of concrete beds and building of masonry pillars must be done to ensure that the surface is dry. This will thereby enhance efficient construction work.
Another important aspect to consider in foundation excavation is maintaining the water table. It must be retained to a level of 0.5m below the bottom ground surface to enhance dryness. It will be important to select different online websites that provide information on construction work. More importantly, you should identify a site that offers the most efficient and cost-effective ways clearing water on the working 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.
The concrete should be protected by moist gunny bags after two hours of laying. After 24 hours, regular curing should be done and be continued for ten days. However, construction over the bed concrete can be started three days after laying the concrete. A leveling course of lean concrete of 75mm is laid to make an even column foundations and raft foundation.
