The owner of a 1970's bungalow was renovating and needed expert advice about how to repair cracked and displaced bricks. We found that footing settlements and rotation was the cause.

House on-the-market with some old subsidence and repaired cracks.

WHICH TYPE OF UNDERPINNING IS BEST?

We get asked this question every day.

FIRST RULE: Which Underpinning is Best for You?

  • Reinforced concrete piers and headstocks are the industry standard due to their practicality and long-term reliability. They should be your top choice in most situations!
  • Steel Screw Piers "Hype": Some charming underpinning sales reps talk about the amazing benefits of steel screw piers, but in most cases it is just sales-talk.ย  Steel screw piers have some benefits in certain applications, but in most residential cases they are not the best option and are often massively over-priced.ย  ๐—ง๐—ต๐—ฒ ๐—ฏ๐—ฒ๐˜€๐˜ ๐—จ๐—ป๐—ฑ๐—ฒ๐—ฟ๐—ฝ๐—ถ๐—ป๐—ป๐—ฒ๐—ฟ๐˜€ ๐—ฐ๐—ฎ๐—ป ๐—ผ๐—ณ๐—ณ๐—ฒ๐—ฟ ๐—ป๐—ผ๐—ฟ๐—บ๐—ฎ๐—น ๐—ฏ๐—ผ๐—ฟ๐—ฒ๐—ฑ ๐—ฝ๐—ถ๐—ฒ๐—ฟ๐˜€ ๐—ฎ๐˜€-๐˜„๐—ฒ๐—น๐—น-๐—ฎ๐˜€ ๐˜€๐˜๐—ฒ๐—ฒ๐—น ๐˜€๐—ฐ๐—ฟ๐—ฒ๐˜„ ๐—ฝ๐—ถ๐—ฒ๐—ฟ๐˜€, if and when required, and at a realistic cost.
  • Polyurethane Resin Underpinning is excellent for lifting wide concrete slabs that arenโ€™t anchored down. In some cases, it can also be effective for underpinning house footings. But soil conditions and footing and slab design may limit the results. We recommend Polyurethane Underpinning for certain cases every month, so contact us first if you are considering this method for ground stabilization or lifting of footings or slabs.

A structural engineer report from Forensic Engineers will tell you which type of underpinning is best for you.

SECOND RULE: Should you trust Underpinning Sales Reps?

Underpinning Sales reps can be very charming. But before signing up for any type of expensive underpinning, do yourself a favour, and contact Forensic Engineers for an expert, independent structural engineer report. Because we are on your side and we arenโ€™t trying to sell you underpinning.

THIRD RULE: How much should you pay for a Structural Engineers Underpinning Report?

The base industry rate is around $800.00-$900.00,ย  depending on the property size and location. If you have been quoted more than this, you should shop around.

Some Underpinning Sales Reps offer to arrange an engineer report for you.

They charge twice the industry rate.
And their engineer works for them, not for you!

But Forensic Engineers are on your side.

We are 100% independent and our reports are for you - not for an underpinning sales rep.

FOURTH RULE: Avoid Underpinning When Possible

In many cases, footings and slabs can be stabilized without resorting to any expensive & stressful underpinning at all. And excessive floor level variations can often be reduced by following expert advice. Talk to Forensic Engineers for the best solutions!

Subsidence & wall cracks? Before jumping into expensive underpinning, contact Forensic Engineers for an expert, independent structural engineer report.

Our Structural Engineer reports are so good, one Foundation Screw Pier Underpinner has copied our procedures in their marketing!

  • Determine likely causes of the damages
  • Give descriptive recommendations for actions or repairs
  • If any underpinning is required, advise which method is appropriate, approx. locations & number required, reliable contractors & approximate costs.
