Top Tips to Laying a Concrete Slab
The following tips will help you lay a superb concrete slab for your new building.
- Do Your Research
It is vital to familiarize yourself with home construction projects before you lay a concrete slab. Also, you need to search for the right contractor for your project.
- Ground Preparation
An excellent ground preparation starts with removing the topsoil. After removing the soil, add a four-inch layer of gravel or stone to make your foundation secure.
- Adopt Vapor Barrier Products
Vapor barriers prevent water from moving up through the porous concrete and wetting items placed on the slab. When laying a concrete slab, ensure you use vapor barrier products, especially those manufactured for concrete.
- Make the Right Mix
The concrete slab should be at least four inches thick. Depending on your region, you need to adhere to building codes to meet the required building standards. Most of these regulations are based on the amount of water used in the mix.
Although adding more water makes it easier pouring, too much of it can make the slab weaker. Therefore, it is advisable to mix fibers with the concrete to produce a more robust chunk.
If you want to create a solid slab, prepare your ground well, mix concrete properly, and utilize sufficient expansion joint. An excellent reinforcement should offer resistance in the middle of the slab, but not on its bottom.
- Expansion Joints
A concrete slab shrinks and expands as humidity and temperature changes over time. To protect the slabs from damages, include expansion joints along the edges of the concrete floor and around other protrusions in the slabs.
- Finishing and Curing
Once you pour the concrete slab, the next step is to smoothen it. To avoid future cracks, cut the expansion groves into wet concrete, and leave the new slab alone.
Curing of the concrete slab occurs when you spray a compound on its top or covering it to prevent evaporation. Also, it is advisable to spray some water on the slab daily as it cures.
