About Rajla
Rajla is a Najran district divided into northern, southern and eastern parts, crossed by Prince Sultan bin Abdulaziz Street with its restaurants, pharmacies and bookshops, and Najran Municipality has built green spaces and a walkway there. Chalets and rest houses spread among the homes mean pools and outdoor seating that need careful waterproofing, alongside insect and rodent control in the open areas. District guide
Why Rajla homes need water tank insulation
Villas, shops and commercial buildings and rest houses and farms define Rajla in Najran, beside Prince Sultan bin Abdulaziz Street. Villas usually rely on a concrete ground tank feeding a roof tank, and any crack in its wall wastes water into the soil unnoticed until the bill rises. Summer heat warms exposed roof tanks and speeds coating breakdown, so reflective external insulation helps. The fix: check the concrete first, repair honeycombing and cracks, then line the tank with a system suited to its age and condition.
