Dry, Durable, Liveable Basement Solutions
Unlock the full potential of your property with basement conversions designed for longevity and comfort.

Whether it’s for a bedroom, gym, studio or utility space, our solutions are tailored for residential and commercial use.
Basements & Water proofing
Korabi Build are basement specialists with a strong track record in converting damp, dark spaces into warm, habitable, and stylish rooms. From media rooms and gyms to guest bedrooms and utility areas, we help clients unlock the hidden value beneath their homes.
We manage all stages — excavation, underpinning, waterproofing, tanking, structural steelwork, drainage systems, and final fit-out. Our waterproofing strategies include Type A (barrier), Type B (integrated), and Type C (drainage) systems, ensuring protection against ground moisture and long-term integrity.
Every basement we build complies with BS 8102:2009 waterproofing standards. We also install ventilation systems, fire safety measures, insulation, and energy-efficient lighting and heating to make each space safe and comfortable.
We offer both retrofit basement conversions and new build basements beneath existing or extended homes. Our engineers and surveyors ensure all works meet local authority requirements and structural calculations are approved.
Clients trust us for our technical knowledge, problem-solving approach, and careful planning. Whether you’re in a period townhouse or a modern build, we’ll deliver a basement that adds real value and usable space — with no compromise on safety or finish.
