Case Study

Repair to Rented Residential Property in Bicester

The Project

Date:August 2019
Property:Rented residential property in Bicester
Type of Project:Collision damage repair
Location in the Property:Porch
Project Size:2m x 3m
Time on Site:1 Day
Lead Engineer:Simon Crook
Saving:~ £25,000

The porch of the rented residential property in Bicester suffered impact damage from a vehicle collision. Shire was contacted by the landlord’s insurance company to investigate and find a solution to repair the damage. 

Investigations concluded that the porch area had slid on the damp-proof membrane (DPM) that was laid under the porch at the time of construction to prevent moisture transmission. 

The Challenge

Investigations concluded that the damage was caused by the impact and no other movement was occurring. The movement had only occurred in the horizontal plane. Jacking was identified as the most suitable and least intrusive option. However, as jacking is usually done vertically, a new method needed to be engineered to jack the building sideways, back into position.

The Solution

The solution was to perform sideways jacking of the porch area. As jacking is usually done vertically, a new method was developed whereby two piles were driven into the ground to the side of the porch to support two jacks placed horizontally. A brace was then created to house the two jacks that used the piles for resistance when moving the porch construction back into position.

The repair took one day to complete and, as there was no need to demolish or vacate the property, saved around £25,000 in time and lost revenue.

Research & Development

Research & Development

We love a challenge! We were first asked to find a solution for repairing terraced houses in the City of London that had restricted access but needed structural support. That was in 1998 and the Shire Pile was created. Since then the R&D team at Shire have developed more products with a focus on restricted access, concrete-free, easy to install, removable and recyclable for a wide variety of applications. And there are plenty more solutions on the way. Contact us if you have an engineering challenge we can help to solve.
