What they say about us
Our Clients
Underwater Pool Repair – Costa Blanca North
At 100% Plumbing, we specialize in restoring your pool’s integrity without ever draining the water. From minor fissures to extensive tile and grout damage below the surface, our certified dive team uses professional‐grade materials and techniques to perform repairs in situ—saving you time, water, and inconvenience.
Advanced Underwater Repair Techniques
Each job begins with a detailed underwater inspection using high-definition cameras and acoustic leak locators. We then prepare the repair area by removing loose debris and rough edges with wet‐sanding tools. Next, we apply marine‐grade epoxy mortars or polyurethane resins that cure underwater, bonding deeply to concrete, tile, or liner substrates and creating a permanent, watertight seal.
Specialized Submerged Services
Our comprehensive underwater offerings include:
Leak Sealing & Crack Injection to stop water loss at the source
Underwater Tile Reset & Replacement for loose or broken tiles
Grout Renewal & Joint Sealing using flexible, chemical-resistant compounds
Coping Edge Patching to reinforce submerged perimeters

All work is completed by dive-certified technicians using industry-approved materials that resist pool chemicals and temperature fluctuations.
