Void Filling in Chelmsford

Underground voids can form beneath buildings and infrastructure due to washout, dissolved materials, collapsed drains, or old mine workings. These voids pose a significant risk of sudden ground collapse. Our void filling service uses controlled injection techniques to safely fill these spaces and prevent further settlement.

Void Filling for Chelmsford Properties

As the county town of Essex, Chelmsford sits on predominantly London clay subsoils, making properties particularly susceptible to subsidence, especially during prolonged dry periods.

London clay is highly shrinkable, expanding when wet and contracting when dry. This seasonal movement is one of the leading causes of subsidence damage in the Chelmsford area. Our void filling service is specifically tailored to address these local ground conditions, ensuring effective and lasting results for Chelmsford homeowners.

Void Filling FAQs

How do voids form under buildings?

Voids can form from collapsed drains, soil washout, dissolved chalk or limestone, old mine workings, or degraded fill materials.

How do you detect underground voids?

We use ground penetrating radar (GPR), dynamic cone penetrometers, and trial pits to locate and assess voids beneath your property.

What materials are used for void filling?

Depending on the void size and conditions, we use geopolymer resin, cementitious grout, or foamed concrete.

Is void filling disruptive?

No, the process is minimally invasive. Small injection holes are drilled and the filling material is pumped in under controlled conditions.
