Crack Injection Services in South Africa
DCCS provides professional crack injection services in South Africa to repair concrete cracks, restore strength, and help prevent water ingress. Crack injection is a specialised concrete repair method used to seal cracks in concrete walls, slabs, beams, columns, basements, tanks, and other structural or surface elements.
Concrete cracks can develop for many reasons, including shrinkage, movement, settlement, water damage, structural stress, poor construction joints, or long-term wear. While some cracks may appear minor, they can become bigger problems if left untreated.
Open cracks can allow water, chemicals, and contaminants to enter the concrete, which may lead to corrosion of reinforcement, structural weakening, and further deterioration.
DCCS repairs concrete cracks using suitable epoxy and polyurethane injection systems, depending on the crack type, movement, moisture conditions, and repair objective. Epoxy injection is commonly used where strength restoration is required, while polyurethane injection is often used to seal cracks and reduce water ingress.
