Concrete Repairs
Wales' Leading Concrete Repair Specialists
Targeted Repairs to Extend the Life of Concrete Structures
At Gwynedd Grouting, we carry out specialist concrete repairs on infrastructure that’s been damaged by age, weather, corrosion or structural movement. Whether it’s cracking, spalling, surface erosion or water ingress, we assess the root cause and deliver durable repairs that restore strength and stability.
We work across a range of structures including retaining walls, culverts, bridges, reservoirs and sea defences – often in coastal or hard-to-access environments.
Our Concrete Repair Services
When you're managing complex infrastructure or repair projects, you need a team that understands the ground, the structure, and the pressure you're under. At Gwynedd Grouting, we combine specialist knowledge with nearly three decades of on-site experience to deliver dependable, long-lasting results.

Crack Repair & Sealing
We identify and treat cracks using specialist mortars, epoxy resins or injection techniques depending on the depth and behaviour of the damage.
Concrete Replacement
Damaged areas are carefully broken out and rebuilt with compatible repair mortars, restoring both appearance and structural integrity.

Surface Preparation
Before repairs begin, we fully prepare all surfaces by removing loose material, rust, dirt or vegetation to ensure long-term adhesion and performance.

Weather Protection
Where needed, we apply protective coatings or sealants to help prevent deterioration from water penetration or environmental exposure.
