This is performed in phases of 2 meters. This is range in between the pits. After the excavations, mass concrete is contributed to the cavity. Mixes are one part cement, 3 parts sand and six parts aggregates. Concrete is made to an excellent consistence and is put into the cavity. Usage type work on the edges. Utilize a rod bar making sure that the cavity under the existing foundation is filled up.
After the underpinning concrete is positioned in the cavity, its enabled to set for two days. The operation is repeated for the next bay. This continues until the required structure is complete. Ensure that the concrete is treated completely prior to packing it. The next thing is to break off the predicting foundation. Cut the concrete flush with the mass concrete surface area. after this is finished for all the bays, soil is then back filled and compacted completely. Watering with a hose is done for consolidation of the soil. This is done upon conclusion of the work.
