The Problem
Optera’s expertise was called upon to investigate the cause of sudden and significant structural cracking to a domestic property in Northampton. The historic property, dating back several hundred years, had been tastefully extended to the rear but had developed 75mm gapping between the underside of the skirting board and the floor.

Our experienced site investigation team attended and through internal and external investigations established that an incoming oil pipe was leaking and that oil contamination, together with water from a nearby recently burst water main, was entering below the property through an oversized hole which had previously been made for a drainage pipe serving the property below ground level. The oil had then acted as a solvent on the floor insulation causing it to dissolve. The result was a sudden loss of support and dropping of the floor, causing cracking to the dividing walls built upon it.

The Optera Solution
Our investigations had recorded high carbon vapours in the property due to the oil leak which meant that the family were very quickly moved out, including the dog who had been sick from the vapours.

Optera Structural Solutions then set to work on the huge task of removing all the contaminated soil from beneath the extension and surrounding it. Working closely with our partnered environmentalist all works were closely supervised to fully determine the correct extent of decontamination.

Once clear of contamination the internal core of the property was fully reinstated and decorated back to its original finish. Surrounding grounds, hot tub and gardens were all reinstated allowing the family and dog back home.

Project Conclusion
This project required quick identification of the problems and a robust solution to ensure everyone’s health and safety were protected at all times. Calling on Optera’s skilled teams, both the insurer and homeowners were impressed with Optera’s professional service and solution.
