Engineering Principles Surefoot engineering principles are based on piling technology using a combination of skin friction and bearing to achieve load capacities in various soil types.

Design capacity calculations are based on Eurocode methods, using refined geotechnical data , for skin friction and bearing pressure.

Surefoot System Surefoot is an “all in one system”, where the unique shape and high strength steel combines to create a very efficient pile cap. Once piles are driven at angle (raked) and the cap secured, the opposing forces of the multi directional piles provides a solid, stable and economical foundation. The system is designed to increase its efficiency when resisting gravity, uplift, shear and moment loads. Ultimately the soil structure absorbs the applied stress.

Our footing system is job specific and is designed according to site soil conditions, and structural design loads etc.

Pile Record A pile record must be kept for each footing and once completed, returned to the consulting Engineer. Refer to Appendix A & B for the Pile Record document and plan example.

DON’T FORGET TO WORK SAFE!DO NOT LEAN ON THE JACK HAMMER!

Then drive each pile alternately in increments with the jackhammer, periodically checking for level. Drive to designed pile embedment depth or refusal see notes Pg. 06.

Finish driving piles with jackhammer until piles are flush with Surefoot plate, specified depth or refusal is reached

Using the jackhammer through the center hole in the Surefoot drive down the plate until piles are tightly locked in.

If refusal conditions met & Engineer has approved cut the piles, note in the bore log and paint exposed metal with cold gal Zinc rich touch up paint

Drill in TEK screws through the Surefoot guides securing the pile to the Surefoot plate.

A pile record must be kept for each footing and returned to the Engineer once completed.

Protect the top surface of the surefoot with a timber block. Tap with a sledge hammer to bed down and level into the soil.

Slide apposing piles through the guide tubes in the Surefoot.

Using a small sledge hammer drive the piles 200-300mm to secure the plate. Do the same with the rest of the piles in the Surefoot.

ServicesBefore starting the installation,all burried services shall be identified using HSG47 Guidelines.

A- Surefoot is rotated to redirect the pile.B- Surefoot plate size is upgraded to allow more

pile placement options. As long as the Engineer is aware of underground obstacles or utilities, a custom design Surefoot can be used to keep the piles from this area. We have 2, 3 and 4 way Surefoot pile options. 2 and 3 way Surefoot could be used to avoid an obstruction. Alternatively plates can be repositioned

ObstructionA- If a pile stops moving when driven in -

driving is stopped. B- it is assured that the other piles are at least half way in to stabilize the Surefoot plate. C- Give the obstructed pile one or two firm hits

with the sledge hammer. If the pile bounces it could be a tree root as service locations would be previsoly located. If the pile feels solid, it could be an isolated rock (refer to Rock Policy). Address these issues as suggested:C.1 Service pipe, reposition/rotate surefoot plate or replace with larger model to change pile direction and avoid the obstruction.

C.2 Tree root - Small Tree: Cut the pile end

at 45o and drive pile through the tree root or deflecting it. Large Tree: As per C.1

Rock policy1. Our general policy is that the designedembedment depth of piles must be achieved or to the “point of refusal”, whichever is the lesser. It is generally avoided the use of Surefoot in “harder” igneous or metamorphic rock such as solid granite or slate unless pre drilling pile holes with a 40mm pilot.*2. The test for “refusal”, is where the pilepenetration for each 15 sections of drive time is less than 5 mm. This is based upon a minimum Jack hammer rating of 41- 45 Joules.

3. The minimum embedment depth of the pileinto soft rock is determined by the consulting engineer. Some softer rock or “floaters” may be fractured by increasing the capacity of the pneumatic hammer. Our standard hollow tubing tends to “core” into softer rocks with sustained pressure. The minimum penetration into the rock is 100 mm. Pre drilling of the piles may be required to achieve the designed or minimum depth.

4. Alternatively, consider whether the Surefootfooting could be slightly repositioned to avoid the rock. Also consider using a greater sized Surefoot plate as standard, which gives greater pile location options, in the case of location critical footings, a larger plate is the best route to take.

Keeping the Surefoot in position Surefoot is kept in the the correct location by using the center guide in the Surefoot plate and drive a pile down to prevent movement. This is recommended on sloping sites.

Driving the pile to specified depth If is there a problem driving the piles at the specified depth the consulting Engineer or Surefoot will contacted to resolve the issue.

Levelling the plateSurefoot should be installed level. Only Surefoot combined with a bolt and baseplate assembly is adjustable for level after installations. If the Surefoot plate is distinctly out of level, its recommended to start again. Remove the pile by cutting it off from beneath the Surefoot and rotate or relocate the plate.

Installing Surefoot in areas of tree rootsInstalling Surefoot in these areas needs special attention. Using NHBC Standard 4.1, the area of influence of the trees is determined by specie, height , proximity to the build and soil type. The foundation depth charts in Appendix 4.2b are used to establish pile depths and assist in determining the negative skin friction that needs to be applied to the piles.

These conditions reduce the absolute capacity of the piles and it is normal in these circumstancesthat either larger surefoot pile caps with more piles or a larger number of pile caps will be used.

Surefoot has been used with success in highly reactive soils, the depth of the reactive soil needs to be determined and a full soil strata analysis performed. The reactive layer works against the piles and applies negative friction, these special case scenarios need to be assessed by the Surefoot engineers prior to specifying.
