Conservatory subsidence
We stabilise and relevel conservatories affected by ground movement, restoring alignment and preventing further cracking or structural damage.
How to stop conservatory subsidence

A conservatory can be a beautiful addition to a home; a bright and airy space to enjoy the outdoors sheltered from the westerly winds blowing in from the Atlantic.
Conservatories are lightweight structures, which means that they are often built with shallow foundations. Unfortunately, shallow foundations are more susceptible to subsidence.
Subsidence occurs when the ground sinks unexpectedly. This can be due to:
Changes in the soil moisture levels because of the climate, which can cause the ground to shrink or swell. This can be a particular problem in the clay-rich soils found in areas like Dublin, Meath and Cork
The roots of nearby mature trees, which can have a similar impact because these suck moisture from the ground, again causing it to shrink
Heavy traffic local to a property can cause sub-surface vibrations which can result in subsidence
Leaking drains which wash away soil particles, particularly in sandy soils, can destabilise foundations
Historical land use such as mining or peatland drainage in rural areas can lead to ground settlement
Possible signs of conservatory subsidence can include:
Unexplained cracks or breaks in the wall or roof glazing
Cracks, sloping or unevenness in the floor
Windows or doors that are difficult to open or close, or which don’t seal properly
Gaps, cracks or separations between the conservatory and the main house
Spotting the signs of conservatory subsidence will act as a warning that something is wrong. Left untreated, subsidence can lead to irreparable damage to your conservatory and allow water and draughts to enter the main part of your home. If you’re concerned that your home is experiencing conservatory subsidence, get in touch with an expert who can recommend the best solution for your conservatory.
At Mainmark, we offer fast and effective subsidence treatments for residential homes. Our cost-effective conservatory subsidence remediation methods can be completed in about a day to minimise disruption to your home.
Mainmark Teretek® resin injection and JOG computer-controlled grouting solutions are non-invasive, so no major excavations are required. Instead, small holes are drilled under the foundation of your conservatory, tubes are inserted to enable resin or cementitious grout to be 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.
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 expanding polyurethane resin. Teretek® has been described as keyhole surgery for buildings. 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 that is similar to resin injection. It uses cementitious grout, which is injected into the ground beneath a conservatory's foundations. Computers accurately control injection amounts in predetermined locations to stabilise the ground and level the conservatory.
