What this gallery can and cannot do.

These photos show known ASR pool distress patterns that are useful for homeowner education and evidence organization. They can help you describe what you see more clearly, but photos alone do not diagnose ASR, prove structural cause, determine responsibility, or replace lab testing, petrography, engineering, legal, insurance, or trade opinions.

Common visual signs in known ASR pools.

Annotated polygonal map cracking network in pool shell — Polygonal map cracking: interconnected cracks that read as a network rather than one isolated line.

Annotated closeup of polygonal ASR map cracking — Closeup map cracking can help show whether the pattern is spreading through the shell surface.

Annotated ASR map cracking and gel-filled fissures — Gel-filled fissures and mapped crack networks are important documentation targets before repairs hide the condition.

Annotated map cracking at pool floor wall transition — Floor-to-wall transitions can show branching cracks that are easy to miss from deck level.

Annotated waterline alkali silica gel exudate at pool edge — White gel or residue at waterline areas should be photographed with location context and closeups.

Annotated gel exudation at pool tile grout joint — Gel exudation can appear at grout joints, cracks, or transitions where material migrates out of the shell.

Annotated coping displacement and gel exudation in raised pool wall — Coping displacement plus gel/residue can point to movement that deserves careful documentation.

Annotated raised wall expansive movement context in ASR pool — Context photos matter: wide views show how localized symptoms relate to raised walls, coping, and waterline features.

Annotated skimmer fracture from shotcrete pressure in ASR pool — Skimmer cracking can become a clue that shell movement is affecting embedded components.

Annotated shotcrete spalling gel exudation and cracked plumbing — Backside shotcrete deterioration, gel, and cracked plumbing need careful photo records before rebuild decisions.

Annotated vertical shell crack below pool light niche — Cracks near lights, returns, skimmers, and other penetrations deserve special attention because they can affect repair scope.

Annotated waterline edge crack at ASR pool tile and coping — Waterline edge cracks should be tied back to location, progression, and nearby movement.

How to use the gallery.

Name the pattern

Use terms like map cracking, polygonal crack network, gel exudation, coping displacement, skimmer fracture, plumbing stress, and shotcrete spalling.

Document the location

Pair closeups with wider photos that show where the symptom sits in the pool: waterline, raised wall, shell floor, skimmer, light niche, return, coping, or backside shotcrete.

Escalate carefully

Use the record to decide what questions to ask a builder, lab, engineer, inspector, attorney, insurer, or repair contractor.
