Concrete Repair & Refinishing
Concrete repairs and refurnish involves stages and procedures carried out to ensure the reestablishment of either failed or deteriorated concrete structures. It is important that before any remedial work can be done, the factors that caused the deterioration must be carefully observed. This would give the engineer an appropriate line of action to follow, and correct the problem and also help prevent future occurrences. The repair method depends to no small extent the size and type of repair required to be carried out. There are different methods concrete engineers use to achieve the desired results, these methods include
Dry Pack Method
This is mostly deployed to new concrete holes of depth equal to or greater than the surface diameter. The preparation of a dry pack mix involves cement and sand in an ascertained proportion before being deployed into the hole as mortar. The desired sticking effect and remedial power are hinged on the mortal's ability to close all the gaps present on the concrete structure properly. This kind of corrective procedure can be carried out for both small and more massive concrete constructions. This process doesn't require so much machinery or particular expertise to carry out.
Concrete with severe cracks may not last if it’s repaired, although professional contractors would advise you not to repair a concrete with multiple cracks. The only durable solution to a concrete with different cracks is to get a replacement. This result of some cracks includes faults, partial collapse etc. Standard concrete replacement methods are required to be carried out for incidents and problems like this. Repairs become more effective when reinforced steel rods can be used to strengthen the structure further. This repair procedure requires the experience and knowledge of a professional engineer. In concrete construction to know the necessary concrete mixture to be used
Damaged Slab Replacement
The replacement of damaged and areas of failures in concrete slabs and structures don't require any particular skill or expertise. It just needs the procedures of suitable construction for replacement. This kind of remedial job can be carried out, making use of bond coats that contain equal amounts of sand and cement. It should be made to accommodate the same consistency as whipped cream and be deployed before concrete placement to prevent the cement mixture from curing or setting. Other alternatives to cement bonding coats could be latex emulsions and epoxy resins. This type of repair work is mostly carried out on concrete slabs or structures that contain such.
Preplacing Aggregate Concrete
Preplaced aggregate concrete requires special commercial techniques deployed for significant repairs, especially underwater repairs of piers and abutments. The first stage or replacement is the removal of the deteriorated concrete. When this is carried out, the sections that need repairs can be seen and framed. These areas are then prepacked with coarse aggregates of sand, cement, or mortar. The totals are subjected to pressure grouting to fill up all void spaces that exist therein.
