- Reinforced concrete pier underpinning is the industry standard due to the practicality and long-term reliability.
- Polyurethane Resin Underpinning can be very effective for densifying and binding founding soils and lifting footings and concrete slabs. It is important that the Resins are injected throughout the soil profile layers that are causing any footing and slab settlements, and not just immediately under the footings and slab. Also, certain footing and slab designs and certain ground conditions may limit the results of Polyurethane Resin Underpinning.
- Steel screw piers have benefits where ground water and collapsible soils are encountered, as well as cases where extra deep piers are needed to find strong natural ground. 𝗧𝗵𝗲 𝗯𝗲𝘀𝘁 𝗨𝗻𝗱𝗲𝗿𝗽𝗶𝗻𝗻𝗲𝗿𝘀 have extensive experience in all types of underpinning and will install the industry standard reinforced 𝗯𝗼𝗿𝗲𝗱 𝗽𝗶𝗲𝗿𝘀, or 𝘀𝘁𝗲𝗲𝗹 𝘀𝗰𝗿𝗲𝘄 𝗽𝗶𝗲𝗿𝘀, if and when required, and at a realistic cost.

Some underpinners offer to arrange Structural Engineer Reports from their own engineers. This is a huge conflict of interest. And the underpinners charge significantly higher rates for a standard Engineer Subsidence Report.
