To an extent all structures can have their foundation ground issues remediated, but with heritage sites the aim is to strengthen the ground and preserve the structure without causing any other damage.
There are typically two options available; traditional concrete underpinning or more modern resin injection methods. At Mainmark, our proprietary Teretek® engineered resin is a two-in-one solution that can improve ground bearing capacity and re-level structures, with minimal intrusion.
The process is likened to key-hole surgery because it is injected through very small tubes into the ground beneath the foundation in a controlled manner, to fill voids and strengthens the ground that has subsided. This can also help raise the building back to level. In cases where more substantial ground strengthening or lift is required, Mainmark’s JOG Computer Controlled Grouting technology is a reliable and accurate solution which can be used in conjunction with Teretek.
As subsidence continues to become one of the biggest problems affecting older buildings in Britain today, it is critical that owners are aware of the advanced solutions now available, helping to effectively repair the ground to ensure the property stands on stable foundations for many more years to come.
