Subsidence, settlement and structural movement of substructures can affect the integrity and safety of a structure. JGP offers extensive knowledge and expertise in the assessment and diagnosis of the cause of movement, as well as cost-effective remediation solutions; such as underpinning or ground improvement.
Structural movements leading to cracks in walls, uneven floors, sticking door and windows can arise due to a variety of issues whether it be ground related, corrosion or decay of structural elements, under-sizing of elements or poor construction. JGP can provide assistance in diagnosing the cause through to the specification, design and detail of remedial works employing traditional low-tech solutions through to latest developments in the market.
JGP can provide assessments of existing foundations, suitability of bearing strata and causes of settlement and movement, such as:
• Movement of the bearing strata due to frost heave, ground vibrations, changing water tables, leaking drains, droughts and trees.
• Failure of poor bearing strata or collapse of historic mine workings or landslips.
• Building alterations that have imposed greater loads on a pre-existing foundation triggering settlement.
We employ various techniques to monitor movement; from installing inclinometers, where significant ground movement is suspected, to simple crack monitoring, which can determine direction of movement and whether movement is on-going.
We believe that good structural design and detail requires sound knowledge of traditional construction techniques and how best to ensure their continued service. JGP offer a full service to assist from initial concept, investigations and reporting through to analysis and design of traditional and modern engineering sympathetically incorporated within the building.
JGP also provide investigation and reporting of structures for possible submission under the Town and Country Planning General Permitted Development Act Class Q for the conversion of agricultural buildings to domestic dwellings.
We can provide basic measured surveys of difficult to access structures for the purposes of providing the Client with drawings of their existing buildings for the basis of further work.
