Different Methods To Concrete Repair
Whatever you need repaired on your property we have the tools and equipment to do it.
All variables regulating the degradation or failure of the concrete building must be determined before any sort of concrete repair can be attempted. This is necessary so that appropriate remedial measures can be utilized in the repair design to correct the problem and prevent it from happening again. For the best outcomes, the following techniques require skilled and experienced guidance. The type of repair and the size of the task will determine the manner of repair.
The Dry-Pack Method
On small holes in new concrete with a depth equal to or higher than the surface diameter, the dry-pack method can be employed. A dry-pack mix is made up of about 1-part Portland cement and 2-1/2-parts sand, which is then combined with water. Then you add just enough water to make a mortar that sticks together. The mortar is ready to be put into the hole in thin layers once it has attained the desired consistency.
When one-half to one square foot regions or bigger extend totally through the concrete sections, or when the depth of damaged concrete exceeds 6 inches, concrete replacement is required. If this happens, it is best to use standard concrete laying techniques. If the repair is coupled with existing reinforcing steel, it will be more effective. A competent contractor with experience in concrete building will be needed for this type of repair.
Replacement of Unformed Concrete
There are no unique processes for replacing damaged or deteriorated sections in horizontal slabs that differ from those employed in normal building practices for placing new slabs. A bond coat comprised of equal parts sand and cement can be used to adhere repair work to ancient concrete. It should have the consistency of whipped cream and be applied right before concrete placement to avoid setting or drying out. Bonding coats include latex emulsions with Portland cement and epoxy resins.
Preplaced Aggregate Concrete
This is a unique commercial method that can be utilized for giant repairs, particularly underwater repairs of a pier or abutment. The following are the 4 steps of the standard process:
Removing the degraded concrete
Mapping out the sections that require repair
Prepacking the area of repair with coarse aggregate
Pressure grouting the gaps between the aggregate particles with a mortar made of cement or sand-cement.
The use of synthetic materials for bonding and patching is one of the most recent innovations in concrete restoration. Because of their great bonding strength, epoxy-resin compounds are widely employed. A bonding coat of epoxy resin is extensively brushed onto the base of the old concrete while applying epoxy-resin repair R 07/08/99 mortars. The mortar is then troweled into place to match the elevation of the surrounding material.
Extra Info About the Repair
All unsound concrete should be removed by sawing or chipping before attempting to restore a deteriorated concrete surface, and the patch area properly cleaned. A sawed edge is better than a chipped edge, and sawing is less expensive than mechanical chipping. Before ordering concrete for placement, a thorough inspection should be carried out to ensure that the following criteria are met:
- The foundations have been adequately prepped and are ready for the concrete.
- Construction joints are free of faulty concrete and are clean.
- The forms are grout-tight, incredibly sturdy, and precisely aligned and graded.
- All of the reinforcement steel and embedding elements are clean, in the right place, and properly fastened
- Necessary concrete delivery facilities and equipment are on the site, ready to go, and capable of finishing the operation without any unanticipated restrictions.
