Foundation and excavation are integral and fundamental processes to clear and prepare land in order for us to carry out our best services. To guarantee delivering our premier services, we need to ensure that there are no hindrances that may prevent us to do so. Carrying out foundation and excavation, without the assistance of professionals, may cost both time, effort and money. Tacoma Concrete Stamping are able to carry out these services with none of the hassle or fuss. The usual procedures for foundation and excavation requires site clearance, setting out, excavation and safety measures based on depth of excavation.
Before the excavation can properly commence, the site needs to be cleared of any vegetation, underbush or any miscellaneous objects like stumps, deadwood, rocks or remains of any previous structures. Any inconsistencies created by the removal of debris which would significantly interfere with the excavation or foundation laying processes must be immediately filled and compacted appropriately.
Setting out refers to the process of establishing the framework and boundaries of the site of the project. This needs to be carried out accurately in order to correspond with the plans approved by the local planning authority. We are able to set out the site through the usage of timber profiles, wooden pegs, string lines and chalk spray. With these tools, the centre lines of foundations can be marked, and accurate measurements can be established.
Excavation is the task of removing the earth from the approved area in order to lay the foundation. On small sites, this task can be executed by manual means such as pick axes, crow bars and spades. In the case of larger structures where deeper excavation is required, mechanical equipment is typically used. Depending on the depth and hardness of the earth, the trench may need to be reinforced if further removal of earth is required. If the earth is extremely soft and loose, planking would be fitted to hold the sites as the foundation is poured.
Once the excavation has been carried out, the foundation will be poured. The concrete is poured into troughs which acts as containers as the concrete hardens, forms and shapes into the required structures. We aim to prevent early drying by spraying on curing aid. However alternatively, polythene sheeting may be used where edges are sealed to prevent wind tunnelling effects which may cause reduction of the concrete’s strength and possible cracking. The concrete foundation can approximately take 3 to 10 days to cure. However during this time, any masonry work can be carried out.
We ensure to be compliant with local regulations and required safety measures and follow-on work should be possible within 48 hours. We are able to provide faster setting architectural concrete if you require a speedier process. It is fundamental to notify our customers that in the case of commercial environments, building inspectors may insist to examine the concrete foundation before any tiles or bricks can be laid and further steps can be carried out.
