Concrete Slab Repair
A concrete slab is a structural element in modern buildings that consists of flat horizontal surfaces made out of cast concrete. In floor and ceiling construction, concrete slabs are steel reinforced for durability and strength.
Concrete slabs are classified either as suspended or ground bearing. A ground bearing slab rests directly on the foundation, otherwise, it is suspended.
Repairs and strengthening.
Repairs are necessary following damage. Moreover, strengthening is similarly important. Weakened structures that may be as a result of construction errors, change in use, or excessive loading require constant maintenance and repairs to enhance their structure.
To determine the cause of degradation, inspection is always the first step. Our general principles around repairs include: Arresting and preventing further degradation, treatment of exposed steel reinforcement and filling of fissures caused by cracking or damaged concrete. The choice of an appropriate repair approach depends on the cause of the damage as well as the nature of repair-is it cosmetic or load-bearing?
What to Look Out For.
Soil investigation. Before picking a site to lay your foundation, the conditions of the soil should be investigated first. This is because, different soils have different properties. Have a professional advice you on the best position to lay your foundation.
Survey your lot. This helps in locating actual corners of the foundation that informs the entire laying of the foundation.
Digging. Have your excavation contractor assist with this.
Footings installation. Since the concrete may be directly poured into trenches and wood forms, have professionals assist with this process. Always employ a quality minded contractor.
Sealing of the footings. This is done to protect the structure from moisture. High quality sealers are used in this process.
Upon curing, stem walls should be created from concrete blocks especially when building a basement. Our masons start with the block wall at the corner of the foundation using leads, which allow a well-built plumb and level wall. This ensures that the walls are straight which is vital in keeping all the walls consistent.
The foundation walls are then treated with an extra layer of sealer to keep off moisture. We use acrylic based sealers which not only act as sealers, but are also curing compounds.
