Resin Injection & Soil Stabilisation

An overview of SAU

          SAU resin injection system offers a excavation free method of foundation movement and soil repair solution which is an alternative to our traditional method of underpinning.

Our injection system is suitable for all domestic, commercial,industrial, and public buildings. We use state of the art level monitoring equipment to monitor the injection process to repair the damaged soil. We specialise in subsidence and structural repairs for domestic properties and commercial buildings with A combined experience of over 150 years in the field.

How resin injection works

01

We set up state of art level monitoring equipment equipment in drains while works are taking place.

02

We locate all other incoming below ground services.

03

We drill a series of holes in predesignated and designed locations and mechanically ram lances into place down to required depths.

04

We then inject the resin in our highly controlled method, repairing, strengthening and compressing the soil below the foundations and lifting if required the structure above.

Resin Injection

Filling and stabilisation of cavities, washed-out voids and gaps.

          Soil solidification, ground stabilisation or soil injection is a method used for improving the stability of soil. For this purpose, special binders are injected into the substrate. These special binders make the foundation soil permanently resistant to mechanical stress. Another objective of soil solidification is to make the soil as resistant to water and frost as possible

Soil stabilisation measures prevent the occurrence of subsidence and resulting deformations in building structures. Barely susceptible vibrations are frequently the cause of subsidence. However, subsidence is also caused by water withdrawal and related soil erosion. This can cause the formation of voids or sinkholes in soft soil layers. In this case soil stabilisation and ground solidification measures are mandatory. Unconsolidated soil can be stabilized and solidified by means of foundation soil injection. The special products used for foundation soil injection measures are based on silicate and polyurethane resin and are characterized by their high strength and fast curing process.

Resin Injection

How it works for you

Our process starts with one of SAU groups experts visiting site to undertake a site survey to determine where the injection process is to take place, how deep into the soil we need to inject and if there is clear access to undertake the work. Once the survey has been completed we send out a detailed work order and insertion plan to be agreed with the client and we book your in the works in a agreeable date. 

A series of small holes are drilled through the ground/slab or soil to facilitate the injection of the ground stabilising resin. We then inject the resin to the desired depth directly below the foundations. The resin then stabilises the ground and in some cases raising to the required height but not in all cases. Our ground stabilising solution is durable and effective, resulting in ground improvement that will last. We reinstate where the work has taken place and complete the whole process for you giving you peace of mind.

The work undertaken is covered by a 25 year guarantee and we issue you with a certificate of structural adequacy. And annuall 12 month reinspection and reissue of COSA certificate.

Cracks and movement can happen in buildings and can progress for a variety of different reasons. It is vital to diagnose the origin cause of the cracking in order to be able to recommend the accurate crack repair system. Most cracks can be diagnosed by the crack pattern and the position on the crack on the wall or structure. At SAU groupwe have our own in house design and investigation team who can offer early investigation and reports we can also offer a full repair scheme using the latest methods and equipment. 

Resin Injection

SAU group specialise in investigating, diagnosing, repairing and the monitoring of cracks.

Lintel Failure - typically caused by the removal of windows and doors on dated properties.

Thermal Cracking - insufficient provision of movement joints is conceivably the most common reason of cracking in cavity wall construction.

Wall Tie Failure - corroding wall ties or insufficient quantity of ties can lead to cracking and in the most severe of cases make the structure or wall collapse.

Lateral Restraint - inadequate tie-ing of the walls to the floor and roof joists causes cracking and bowing interior and externally, mostly on dated properties.

SAU group can offer you an a free initial consultation to find out the origin cause of the crack repairs to your property, then we can offer you with the most economical contemporary repair systems, with the slightest disturbance to all involved. SAU group operatives are extremely skilled and qualified in dealing with all kinds of current day repair systems for crack repairs. This may mean fitting masonry reinforcement (Helical Bars), resin injection system.

Testimonials

Mr Adams, London

"It was a stressful time but SAU made it a little bit less, so I don’t think we are ever going to build an another two level basement but if we did or someone we know does we will only recommend SAU."

Mrs Cunningham, Bristol

"Great service, the guys on site were always helpful and explained the process, evan though they were busy. We didn’t have to deal with any other engineers as SAU dealt with the whole process for us."

Mr Lee, Glasgow

"The office and site team from SAU have helped us massively from the beginning of our claim to the finished product."
