A basement must be carefully designed and built to withstand soil pressure, groundwater, and structural load. We work step-by-step to ensure a stable and watertight structure. Before construction begins, we conduct ground investigations, drainage assessments, and structural planning to ensure the site is suitable for all construction work. Our engineers then design a plan that includes reinforced concrete, retaining walls, and waterproofing systems.
Once we begin groundworks and excavation, strict safety measures are followed. Support systems, temporary civil basement works, and structural sequencing are put in place that help prevent movement of surrounding soil and protect property foundations. After the main excavation, we install RC slabs, RC walls, and effective waterproofing to avoid leaks, dampness, or flooding.

The timeline for basement construction depends on size, basement design, access, and
ground conditions.
On average, a basement can take several weeks to a few months
from
excavation to structural completion.
Larger or complex basements may require
additional
time for concrete curing, waterproofing, and inspections.
Basement construction often requires planning permission and structural approval. We guide you through the process and can work with your architect or consultant to ensure compliance with local regulations.
