The Foundation
of Every Build
Before any structure goes up, solid groundwork must be laid. We handle all aspects of drainage and groundwork preparation with precision and care — from small domestic builds to large multi-plot developments across the North East.
Safe, Stable,
Built to Last
Groundworks are the least visible part of any construction project — but they're the most critical. Poor drainage or inadequate foundations cause problems that can be expensive and disruptive to fix years later. At Gray's, we get the groundwork right from the start, every time.
We handle everything from initial site clearance and excavation through to drainage installation, concrete bases, soakaways, and full site preparation for extensions, new builds, and landscaping projects. One team, from ground level up.
Our groundworks teams operate across the whole of the North East — Newcastle, Sunderland, Gateshead, Durham, and beyond.
"Everything above ground depends on what's below it. We lay the groundwork that gives every build the solid, stable foundation it needs to last a lifetime."Gray's Signature Builds

Our Installation Process
We visit the site, assess existing ground conditions and drainage, and provide a clear, itemised quote covering all required groundwork.
The site is set out accurately with correct levels established — ensuring drainage falls, foundation depths, and all excavations are precisely controlled.
Dig-out to the required depth, removal of spoil, and preparation of formation level — all completed using appropriate plant and equipment.
Pipe runs laid at correct falls, backfilled in layers, and tested. Inspection chambers and soakaways installed to specification.
Foundations, floor slabs, and bases poured and finished to the required specification — reinforced where required by the structural engineer.
All excavations backfilled and compacted in layers. Site left clean and ready for the next phase of your build.
Get the Ground Right
Groundworks failures are expensive and disruptive to fix once a building is up. We bring the same precision to the work below ground as we do above it — because a building is only as good as its foundations.
