02 / Our Services
We begin with professional consultation and feasibility advice, then engage trusted architects and structural engineers to create bespoke designs. This fully integrated approach means we deliver complete design-and-build solutions from start to finish.
New basements beneath existing homes, deepened cellars and full subterranean levels: excavated, underpinned, formed in reinforced concrete and tanked before a single finish goes in.
Explore basement construction
Designed waterproofing installed to BS 8102 principles, watertight structure, cavity drainage and managed groundwater, before a single sheet of plasterboard goes up.
Explore structural waterproofing
Traditional mass concrete underpinning, needle beams, raking props and piled solutions: executed pin by pin, in an engineered sequence, with the building monitored throughout.
Explore underpinning & piling
Removing walls, forming openings and transferring loads through new steelwork, reconfiguring how a building works inside without compromising what holds it together.
Explore structural alterations
Frames, beams, column grids and metal decking, fabricated to the engineer’s drawing and installed into buildings that are often being held up by something temporary while we do it.
Explore structural steelwork
Reinforced slabs, ground beams, raft foundations and site preparation: set out accurately, reinforced properly and poured in the dry.
