FAQ

 

Building control and code compliance?

Surefoot is basically a displaced micro pile and pile cap solution. These are long standing civil engineering techniques completley covered by BS structural codes with an immense existing body of knowledge to back it up. Piles are installed in angle (battering) to create an array, increasing capacity. Again, another civil engineering technique. The only difference is that this is a minature version.

Surefoot Europe is a CE certified EN 1090 structural steel fabricator and the product is a steel micro pile system. The solution is always calculated by an independant stuctural engineer in combination with a soil report and a penetration test.

Relevant structural codes;

BS EN 1991-1 Eurocode 1, Actions on structures.

BS EN 1993-1-1 Eurocode 3, Design of steel structures.,

BS EN 1997-1:2004, Eurocode 7 Geotechnical design.

BS EN 14199:2005 Execution of Special Geotechnical Works: micro piles

BS EN 12699 Displacement piles

Surefoot vs Concrete?

For many applications Surefoot offers a superior solution to traditional concrete foundations. This is especially true when building on sloped sites, weak soils or the structure is subject to large bending moment loads. Surefoot eliminates or greatly reduces excavation and heavy machinery in the job site.

Surefoot vs other solutions?

Other Steel pile systems such as helical piers and screw piles are relatively expensive solutions that are normally specified when there is a particular construction problem to resolve. Surefoot offers various advantages over these systems, Surefoot is more precise, has higher capacities (Price/capacity ratio) and is easier to install. Specialist bulky machinery and other equipment are not needed, just small portable tools. Surefoot is the only system that can compete with concrete in normal building conditions.

What can you build with Surefoot?

Surefoot can be used to support practically any building structure that requires a foundation. It has been proven in a wide range of sectors and uses. For special projects and exceptional loads the Surefoot capacities can be further increased by creating groupings of 4 or more units joined by custom designed steel sub frames. Surefoot is fabricated to EN 1090-2 Execution class 2 which covers multi story and public buildings so its potential use is very wide reaching either as a stand-alone foundation system or in combination with traditional concrete foundations.

What are the maximum loads of Surefoot?

The Surefoot loads are determined using the relevant Euro code calculations. Surefoot can receive loads of up to 30 tons depending on the model. Further capacities can be achieved by combining models in groups and joining with Steel sub frames. Surefoot is one of the only systems that has the capacity to resist high bending moments which basically means that it can be used for many, many purposes beyond typical construction such as communication towers, masts and wind turbine installations.

How much can you save over traditional foundations?

Potential savings are job specific and directly related to the construction system employed. The savings are not just in materials, but also in machinery, labour, eliminating weather delays etc. Surefoot is a foundation system with instant bearing capacity, projects continue immediately without delays and there is more control over the building schedule. It’s installed with low cost portable equipment, a complete foundation system can be delivered to site in a small van, its lightweight and installers can carry footings by hand.

Send us details of your project and we will offer a solution optimizing the use of Surefoot for your internal cost comparisons.

How long does it take to install?

The smallest SF100 and SF200 bases can be installed in as little as 10 minutes, the larger high capacity bases SF500 and SF600 take between 30 and 45 minutes. Imagine, a complete foundation for a home installed in under a day with construction commencing the same day.

Which constructions benefit most?

Any construction type can benefit from reduced costs by using Surefoot. However where the largest savings are realized are in poor soils or where deep conventional foundations are specified. In sloped sites, Surefoot can realize exceptional cost savings by not levelling or interfering with the natural ground patterns, eliminating the use and mess of heavy machinery and diggers.

Where is Surefoot made?

The Surefoot system although designed and developed in Australia is fabricated in a state of the art facility in Europe, manufactured using laser cutters and high speed robotized welding cells. They are high quality structural Steel elements manufactured to EN 1090-2 EX2.

Environmental impact?

Surefoot does not disturb the land and soil of the job site. There is no need to level, cut and fill or change the landscape (unless specified). Surefoot does not disturb natural drainage patterns and can be installed around treed areas avoiding the root systems. Surefoot eliminates or drastically reduces excavation even when used in conjunction with concrete.

Installation in sloped sites?

It’s not necessary to level plots to build with Surefoot, Surefoot permits the construction to adapt to the land without increasing costs, and the system can add value to heavily sloped sites that make traditional foundations prohibitive.

Avoiding existing infrastructure and cabling?

When installing Surefoot in dense urban and industrial areas it is prudent to have plans of existing infrastructure to avoid when inserting piling. If this is not available, cabling and pipes can be located with a basic CAT scanner. Once located there are two options, change the location or position of Surefoot to avoid the infrastructure or use a 2/3 way Surefoot model that has the driving angles of the micro piles changed.

Avoiding obstacles or boundry conditions?

By using the Surefoot 2/3 way bases with the corrected micro pile angles, Installation can avoid known obstacles such as foundations of existing buildings or boundary conditions of the plot.

My building plot has trees, can i use Surefoot?

Yes, NHBC Standards document “4.1 building near trees” are taken into account as a basic guide. In general Surefoot piles need to get past the upper strata influenced by the tree root system and into more stable material. However piles are not effected the same way as conventional foundations are, please contact us for more information.

Highly shrinkable clays?

Surefoot can be used in all soil types. In the case of highly shrinkable soils/London clays, the Surefoot piles in most cases need to penetrate to stable strata and a negative friction affect of the reactive clay needs to be taken into account. Please contact us with details of your project and our engineers can advise on a project by project basis.

Corrosion and design life?

Surefoot use TATA Celsius420, a 420n/mm2 super steel as its standard pile. Available in 4 and 5mm wall thickness, this steel affords excellent corrosion performace with design life in excess of 100 years in standard soils.
