Introduction

Not every damaged surface needs to be demolished and rebuilt. A narrow crack, a deteriorating concrete section, or a weathered substrate can be addressed with the right repair technique.

The challenge is knowing which solution fits the defect. The different types of surface repair in the Philippines, specifically for residential, commercial, and industrial structures, are designed for various levels and forms of damage. 

Understanding how each method works can help property managers choose the best approach before applying a new finish or carrying out further construction work.

Crack Injection

Crack injection is typically used when cracks extend into the concrete and require more than a superficial patch. The method involves introducing a repair product into the crack through injection ports to allow it to penetrate the affected spot.

Depending on the repair requirements, epoxy or polyurethane-based materials may be used. Epoxy can bond and restore structural continuity in suitable cracks, while polyurethane can be useful where some flexibility or water resistance is necessary. The crack should initially be evaluated to identify its cause and whether injection is a good solution.

Patching and Mortar Repair

Small holes, chipped concrete, and spalled sections can be resolved by patching or mortar repair, where the missing material is restored. The damaged area is first cleaned and prepared by removing loose or deteriorated elements.

A suitable repair mortar is then positioned into the prepared section and finished to match the surrounding surface as closely as possible. This method works well when the damage is limited to certain spaces, but simply covering deteriorated concrete without removing unstable material can result in poor adhesion and persistent damage.

Surface Resurfacing

When a surface has widespread minor deterioration, discoloration, roughness, or shallow imperfections, resurfacing can be a great alternative to repairing every small defect individually. It involves applying a new repair or coating layer over a well-prepared substrate to restore its appearance and functionality.

For Philippine developments exposed to moisture, temperature shifts, and regular wear, choosing a compatible resurfacing product is vital. The current surface must be cleaned, repaired when needed, and planned based on the manufacturer's requirements before application.

Routing and Sealing

This technique is used for cracks that are suitable for surface-level treatment, specifically if the goal is to prevent water and substances from entering the crack. It also involves widening or shaping the crack to form a suitable platform before cleaning it and filling the prepared space with the right sealant. 

Unlike structural crack injection, the repair commonly resolves the surface opening instead of bonding the concrete throughout the depth of the crack. Before sealing, however, the cause and movement of the crack should be considered. Sometimes, a sealant may not be good for cracks caused by seismic activities or underlying failure.

Shotcrete and Guniting

Shotcrete and guniting involve applying cementitious material to a surface using pneumatic equipment. The high-velocity application allows the material to adhere to vertical, overhead, or irregular surfaces.

These techniques are commonly associated with larger repair, strengthening, or construction applications where conventional placement may be challenging. They can restore deteriorated concrete sections, build up surfaces, or form new layers over substrates.

Because the product is expected at high velocity, application requires professional contractors and efficient equipment. Surface planning, material mix, thickness, reinforcement, and curing should all be controlled to attain the desired outcome.

Crack Stitching

It’s a repair method that stabilizes suitable cracks in masonry or concrete through reinforcement across the damaged spot. Steel bars or specialized stitching parts are installed across the crack and embedded into the surrounding material.

Rather than simply filling the opening, crack stitching ties the spaces on either side of the crack together. Moreover, as with other repair processes, the underlying cause should be determined first, as it’s not a universal solution for each type of movement or structural damage.
