Trust Partners Geo-Group is among Kenya's most experienced basement excavation contractors, delivering safe, compliant substructure works for developments throughout Nairobi and across the country. Our teams bring deep expertise in managing the complex soil profiles, groundwater conditions and tight urban access constraints common to sites in Parklands, Kilimani, Upper Hill, Kileleshwa, Lavington, South C, Karen, Syokimau, Thome, Thika Road, Kiambu Road, Athi River, Mlolongo, Industrial Area, Ruiru and Ruai.
Our bulk excavation capabilities extend well beyond the capital. We maintain an active project portfolio in Mombasa, Kisumu, Nakuru, Thika, Eldoret, Garissa, Malindi, Nyeri, Kitale, Meru, Naivasha, Kakamega, Embu, Machakos, Kiambu, Nyandarua, Laikipia, Bomet, Vihiga, Murang'a and Bungoma. Whether the brief calls for a standard 4-metre residential basement or a mega excavation exceeding 30 metres, we mobilise the right equipment, engineers and safety protocols for the job.
What distinguishes us from other excavation companies in Nairobi is our end-to-end delivery model. We do not simply remove earth — we assess ground conditions, design dewatering and shoring strategies, manage utility coordination, execute controlled excavation, and complete the work with quality-assured backfilling and compaction. For a deeper look at how we approach these projects, read our guide on understanding basement excavation in Kenya.
