Ground Stabilisation
Ground Stabilisation
Total specialist maintenance are a specialist Ground Stabilisation contractor, Our Ground stabilisation services is a method using Resin injection technology in which poor/un-compacted/ loose sub soils can be made into a cohesive stable medium resulting in a better performing sub base. Our Ground stabilisation services negates the need to remove or excavate the existing surfaces such as, Asphalt roads, concrete floor slabs, pathways, rail track and sub base and embankments.
From experience as ground stabilisation contractor, the cost of excavation and transporting of excavated waste is prohibitive and if you stabilise you do not have to take materials from the site for costly disposal. Brownfield sites are an ideal case for this process.
Advantages of Resin Injection in Ground Stabilisation
- Ground that requires stabilisation does not need to be dewatered in advance or during the injection works.
- The kit is small and highly mobile, allowing access in very tight locations; through doorways etc.
- The resin is injected in low viscosity liquid form, allowing it to penetrate into pores inaccessible to conventional cementitious grouts.
- The cured resin is hydrophobic and does not change its properties once cured.
- The resin reacts quickly and can be adjusted with the use of accelerators.
- Low pressure injection prevents the possibility of hydro-fracture of soils and damage to adjoining structures.
- The foaming action of the resin significantly reduces the volume and weight of injected product.
- Low pressure injection prevents the possibility of hydro-fracture of soils and damage to adjoining structures.
- The foaming action of the resin significantly reduces the volume and weight of injected product.
- Environmentally friendly system
Method
Total specialist maintenance are proven specialist in resin injection technology. By careful injection under low pressure, the resin flows into the ground via lances, the resin then reacts to a pre-determined set and expansion rate, then further permeates the soil throughout the reaction process. The resins deployed are ideal for use in sensitive environmental areas such as canal embankments due to their European drinking water approval . Once the resin has reached its maximum expansion the resins will continue to cure, forming a uniformed stabilised sub base. The cohesive nature of the ground improvement controls water and fines within the soil allowing for the installation of underpins and foundations where required.
Injection lances are driven using our specialist lance installation technique up to a depth of 12 metres where required. Assurance of placement of the injection resin is achieved by the latest lance extraction technology ensuring a uniform fill is achieved forming a stabilised load bearing and an increase in cohesive properties.
As part of our quality assurance process Total specialist maintenance provide Ground penetrating radar surveys, or alternatively a ground stiffness surveys using the latest technology.
Throughout the ground stabilisation process installation we ensure our strict quality assurance procedures is adhered to with temperature, volume of fill, product batch numbers all being recorded throughout the process.

Total Specialist Maintenance polymer resin can be adapted to meet the required structural loading to meet our clients needs on project by project basis
Most soil types are suitable including:
- Made up ground/ general fill
- Granular soils such as sands and aggregates
- Cohesive soils with a fine grained content
- Organic soils such as peat
- As the material is a plastic based material a duration in excess of 100 years
- Accelerated age testing has been carried out on the polymer resin. The results of this testing demonstrated that in extreme conditions of fluctuating temperatures and chemical attack, the products under test remained unaffected after the maximum test duration of a simulated 70 year period
- Material stable between -20 to +90 °C.
With the use of polymer resins and the use within the ground, concerns regarding the environmental impact and the safe use are valid. The polymer resin is extensively tested and meets the hygiene institute drinking water standard and is also REACH assessed therefore will have no detrimental effect on ground water, fish stocks, or wildlife and is also safe for use by our operatives as the material is odourless and free from all solvents which also make the material safe to use for our operatives in close proximity, client staff, office staff, general public and homeowners who choose to us this system within their homes.
Due to the controllable set times of polymer resin, unwanted run off materials can be eliminated, unlike a traditional cementitious grout which has significantly increased environmental impact due to the high PH value of the grout and the unwanted run off. This product is used extensively across the country and across Europe on drinking water retaining structures, rivers, canals and other environmentally sensitive areas
Total Specialist Maintenance can also provide certification and approvals upon request.
The polymer resin once cured, is an inert plastic that is treated as general building waste, with no additional hazardous waste disposal charges
Yes, The polymer resin is suitable to use when ground water is present and will have no detrimental effect on the material or technical properties and can used in both saline (sea water) and fresh water
No, The polymer resin is suitable to use when ground water is present and will have no detrimental effect on the material or technical properties and can used in both saline (sea water) and fresh water
The polymer resin has low permeability, due the polymer resin being a closed cell material with a hydrophobic effect
The polymer resin has an adjustable set time which can cure within seconds or up to 15 minutes depending on the permeability of the ground and required bearing capacity.
Initial cure is achieved within 15minutes and will have early strength gain within hours making loading possible on the same day
Yes, the polymer resin fills voids underneath the floor slab having a reducing effect on vibration.
The Polymer resin can be installed during extreme heat and very low temperatures as the material has an adjustable set time
Yes, the ground can be excavated easily using normal excavation plant and equipment and where this is not possible traditional hand digging methods can be deployed.
Yes, however we would look to work with a structural engineer and provide a design solution in line with the project requirements
No, the Polymer resin is typically lighter than soil or fill
The plant and equipment is all very portable and can be easily transported on restricted weight bearing ground, where access issues are also a problem. Such as rear elevations of properties, river and canal banks ect.
