{"ai_json_enabled":true,"answer":"Arrange a wet-season drainage check with an independent builder or land-surveying professional. Ask them to document the actual water flow paths, ground slopes and whether surface water from driveways, terraces, and pool overflow is directed away from walls and into proper outlets. Request a written report with photos or video taken during or after heavy rain, plus level measurements of critical points (foundations, slab edges, and garden beds). Compare these findings with any available grading plans, drainage outlets, culverts and nearby ponding areas to see if water is being directed to a safe outlet. Talk to neighbours about ponding history and maintenance records to gauge consistency over seasons. Ensure the report notes any landscaping features that could mask low points and suggests practical remediation if performance is not as expected. Finally, check whether the contract includes a remediation clause or a seller obligation to fix drainage problems after purchase, and verify how post-purchase rectification would be funded or scheduled. Dry-season photos don\u2019t prove wet-season performance; require live evidence instead.","answer_source":"openai_conversational_breadcrumb","category":"Property Inspection & Coastal Risks","category_slug":"property-inspection","confidence":"grounded_in_approved_property_guide_context","conversation_depth":1,"conversation_followup_type":"evidence","conversation_parent_slug":"how-important-is-drainage-in-khao-lak","conversation_reason":"To move from general guidance to concrete proof of wet-season drainage performance.","conversation_root_slug":"how-important-is-drainage-in-khao-lak","created_at":"2026-10-09T19:32:31+00:00","daily_publish_cap":3,"date_published":"2026-10-10","display_date":"2026-10-10","drip_batch":"2026-10-10","drip_status":"daily_auto_published","freshness_warning":"Property prices, availability, construction progress, rental rules and legal requirements can change.
