Course Overview
The Cabro Fixing & Drainage course is an intensive, practical training program designed to equip participants with the technical skills required to construct durable interlocking concrete block pavements (cabro) and efficient surface and subsurface drainage systems for residential, commercial, industrial, and public infrastructure projects. The course covers site preparation, surveying, ground leveling, subgrade improvement, base construction, cabro installation, drainage design, stormwater management, and project finishing in accordance with industry standards.
Participants will gain extensive hands-on experience using professional tools and equipment to install driveways, walkways, parking areas, courtyards, roads, and drainage channels. Through workshop activities and field-based construction projects, learners will develop the competence to deliver high-quality paving and drainage systems that ensure structural durability, proper water management, and long-term performance.
