Royal Concrete Slabs contributes significant value to all concrete slabs and provides dynamic solutions to a multitude of industries. It should be noted that all of our products are produced to the highest standards and aligned to structural specifications.
In this article, we will be looking at concrete laying and casting and the definitive processes that are followed for preparing the slab area for concrete laying. Royal Concrete Slabs are proficient and knowledgeable in paving the way for durable and sustainable concrete laying.
Proper planning and groundwork of the concrete laying and slabs will keep your concrete crack-free. There are depending factors for the ground floor and foundations such as the condition of the existing soil, plastic on surface beds, the climate as well as the weight distribution of what the concrete would be used for. For rib and block slabs, engineers will check props are in place, dpc membranes and soft board assists with movements and minimise cracking.
The next preparation phase is ensuring that each layer of the base is compacted and the correct machinery is used during each phase. By using a vibrating plate compactor, the concrete or sand is designed for compacting the soil when backfilling the trenches. Ensuring the correct reinforcement steel mesh or rebar are in place under engineers supervision is essential for structural integrity.
Adding water to the mixture is also critical for laying down the concrete. In order to achieve maximum compaction, it would be ideal to spray down each lift with the concrete slab. Oversaturated bases would not compact well either and also assists with minimising dust accumulation.
Keep the forms as straight as possible by attaching the screws and form boards accordingly. The direction and weight distribution is equally important with the alignment of the slope and should be taken into consideration when preparing the area for concrete laying.
