About this service
Beneath every well-functioning property lies a complex network of civil infrastructure. AAS Technical Services constructs the essential underground systems that keep sites dry, safe, and connected. We excavate and build robust storm water and sewer drainage networks, ensuring exact pipe gradients (falls) so gravity does the work effectively without blockages.
Our civil teams construct durable concrete manholes, inspection chambers, and catch pits, fitted with heavy-duty cast iron or ductile covers. We also handle the civil trenching and encasement required for underground utility ducts—providing safe, concrete-protected pathways for main electrical cables, telecommunications, and water service connections. From a single villa drainage modification to infrastructure works for a commercial plot, we build the unseen civil works to the highest municipal standards.
