Sansiri raised land and road levels 20-30 cm, added retention ponds and 1 m barriers after the 2026 floods; Amata industrial estate is filling land up to 2 m and offering buybacks to relocating factories. Brokers expect weaker demand and possible price drops for flood-hit east Bangkok areas such as Ramkhamhaeng, Lat Krabang and Min Buri, and buyers are checking flood history and drainage before purchase. Land owners are advised not to sell in a hurry. If you run a shop, factory or property near canals or low ground in these zones, check your flood exposure and the cost of raising stock or premises before the next rainy season.
