Subsidence enquiries covered across Gillingham
Enquiries from Gillingham go to firms that understand how shallow Victorian footings behave on chalk slopes and infilled ground. A specialist looks at whole terrace runs rather than single walls, because movement in one house affects its neighbours.
- Shallow footings on chalk
- Victorian and interwar terraces here often sit on narrow brick footings laid directly onto chalk, which shrinks and washes out unevenly over decades.
- Infilled ground
- Parts of Gillingham were levelled with loose fill before building began, so foundations settle at different rates along a single terrace row.
- Whole-run assessment
- A dropped bay or stepped crack rarely stops at a party wall, so a specialist examines the entire run of houses to find the true cause.
What owners in these terraces usually ask
These are the ordinary questions people ask when they first notice a stepped crack or a bay window dropping. None of them is too small to raise with a specialist.
-
Why is the crack stepped rather than straight?
Stepped cracking follows mortar joints because the ground beneath one end of the wall has moved more than the other.
-
Does my dropped bay mean the whole house is sinking?
Bays have their own shallow foundations, so they often drop independently while the main wall stays relatively level.
-
Will the movement spread to the houses either side?
Terraces share loads through party walls, so settlement in one section can pull the neighbouring houses down gradually.
-
Can I just fill the crack and wait?
Filling hides the symptom but leaves the cause active, so the filler splits again once the ground shifts further.
-
How does anyone know if it is subsidence or just age?
A specialist digs trial pits and takes soil samples to see whether the ground itself is moving or the masonry is simply old.
Ways a specialist firm stabilises ground
Each method suits a different type of movement. The right one depends on what the investigation finds beneath the footings.
