Total Specialist Maintenance (TSM) is a specialist contractor in increasing load load-bearing capacity of the ground on a national basis in a vast number of market sectors. Our ground-bearing enhancement services are used in instances where there is a requirement for the ground to sustain an increase in loading. This can be achieved in a way that does not impact current activities and negates the cost of excavation, transportation of excavated waste and replacement fill costs. Our ground bearing enhancement technology does not require the removal of existing surfaces such as Concrete slabs, Asphalt roads and Track and ballast formations, and can be placed at specific depths down to 12 meters.
A site survey is needed to gauge the existing ground-bearing capacity of the soils using the cone penetrometer method and soil stiffness survey. A borehole survey is also required to gain an understanding of the ground makeup. The preliminary testing of the ground will provide us with the relevant information so that a specification for enhancement can be drawn to meet our client’s needs.
From the information provided, a pattern of drill holes and depths can be drawn up. The number of materials that are required to increase the ground bearing capacity can then be calculated.
From the site survey, a grid pattern can be drawn up to enable 25mm holes to be drilled through the concrete slab, asphalt road surfaces or track and ballast formations before our resin is injected at specific depths up to a maximum depth of 12 meters to increase the ground bearing capacity.
Post application testing is carried out using soil stiffness analysis to ensure that the performance upgrade required has been achieved.
Our increasing ground-bearing capacity services offer a long-term, cost-effective solution with minimal disruption and rapid return to service times.

Yes, The system can be used on all types of buildings and structures that are both new build and existing structures where movement or subsidence has occurred or excavations processes are difficult making traditional solutions not viable.
Yes, our system can be designed to suit all soil and fill types such as cohesive soils, made ground and granular fill
Yes we offer an installation and material degradation warranty on a project by project basis.
Yes, the geopolymer structural polyurethane injection resin has certification for the safe use of within potable drinking water environments and has the approval for the safe use for the installation into ground water making it also safe for the use next to rivers and canals having no effect on fish stock or wildlife
Yes, however there would some inconvenience like there would be with any construction/building works within or outside a property
In short the answer is yes, but it really depends on how much weight, the soil quality, and the nature of the geology and subsurface structures. There are several instances where we have helped repurpose foundations to handle dramatically increased loads, such as silos, cranes, heavy equipment and machinery, and structural support columns. In each instance, the injection approach was uniquely designed to take advantage of the current soil and geological makeup of the site.
The use of polyurethane grout injection for soil densification and structural rehabilitation has been revolutionising the way local authorities and construction companies think about rehabilitation vs. replacement. Due to cost-effectiveness and innovations in injection techniques, the viability of the solution has been “fast expanding” and the applications are spanning across a variety of uses, such as roadway lifting and stabilisation, railway stabilisation, seawall stabilisation, and building foundations commercial properties where change of use is required and domestic properties.
There are various ground improvement techniques: Grouting, soil compaction, soil mixing, cement/lime stabilisation, Vibro-replacement and the use of geotextiles.
Total specialist maintenance provides solutions to deliver ground improvement through permeation grouting which involves the use of structural polyurethanes that can offer a less intrusive and more cost-effective solution than traditional systems as outlined above which also negate the need for deep excavations and large plants on site.
Permeation grouting is where cracks, joints or any other voids are filled with flowable grouts to create a stable mass. Permeation grouting uses chemical grouts and cementitious grouts. It is commonly used:
