How to stop conservatory subsidence

Conservatory subsidence is a common concern for homeowners. If you suspect your home is experiencing subsidence, it’s important to get the problem remedied as quickly as possible to prevent further damage.
At Mainmark, we offer fast and effective subsidence treatments for residential homes. Our conservatory subsidence remediation methods can be completed in about a day, saving you time and money, as well as minimising disruption to your family.
Our Teretek® resin injection and JOG computer-controlled grouting solutions are non-invasive – meaning no extensive digging or excavating is required. Small holes are drilled under the foundation of your conservatory, and then resin or cementitious grout is injected into the ground underneath. This process:
Gently lifts and re-levels the conservatory, returning it to its correct position.
Fills in voids that may have developed under the foundation, strengthening the support.
Improves the ground, increasing the soil’s load-bearing capacity and mitigating liquefaction under your conservatory.
With our conservatory subsidence treatments, you can rest assured that your conservatory is on solid and stable ground, so you can get back to enjoying your space without any concerns about structural issues.
What are the signs of conservatory subsidence?

A conservatory is a beautiful addition to a home, giving you a bright and airy space to enjoy the outdoors while also being sheltered from the elements. However, conservatory subsidence is a common concern that homeowners should be aware of.
Because conservatories are lightweight structures, they are often built with shallow foundations. Unfortunately, shallow foundations are more susceptible to subsidence.
Spotting the signs of conservatory subsidence could give you an early warning that something is wrong and allow you to enlist expert help before significant damage occurs. Possible signs of conservatory subsidence can include:
Unexplained cracks or breaks in the glass walls or roof of the conservatory
Cracks, sloping or unevenness in the floor
Windows or doors that are difficult to open or close or which don’t seal properly
Gaps or separations between the conservatory and the main house
If left untreated, conservatory subsidence can lead to irreparable damage to your conservatory. It can also cause leaks and draughts in the main part of your home and create a safety hazard. If you’re concerned that your home is experiencing conservatory subsidence, get in touch with an expert as soon as possible.
Technologies for treating conservatory subsidence
Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.

Teretek® – Resin injection for conservatory subsidence treatment
Teretek® resin injection is an engineered solution for re-levelling subsided conservatories, using a plural component, expanding polyurethane resin. Teretek® works in a way similar to keyhole surgery. Small holes are drilled under the foundation in order for Mainmark’s proprietary, environmentally inert resin to be injected under the foundation, improving the stability of the ground and re-levelling your conservatory.

JOG computer-controlled grouting for conservatory subsidence treatment
JOG computer-controlled grouting is a multi-point injection technique tat can be sued to remedy conservatory subsidence. This technology typically uses cementitious grout to re-level structures, including conservatories. This means that cementitious grout is injected under the foundations, using computers to accurately control the injection amounts in the various predetermined locations.
