Can it lift a house back to level?

Lifts of up to around 25mm during injection are routine. Larger drops are stabilised first then addressed with internal levelling work.

How long does it last?

Cured geopolymer resin is chemically inert and doesn't break down. Most specialists offer a 10-year warranty.

The cured resin is non-toxic and inert. Manufacturers publish independent environmental test data.

Resin Injection in Bexley

Re-support sinking foundations in days, with no excavation and no need to move out.

Worried about it? Here's what happens next.

You've heard underpinning is a six-week, garden-destroying nightmare and you're hoping there's another way. In most south east London cases there is. Resin injection re-supports the foundation in days, with no excavation and no skip on the drive.

1. Soil and footing check

A specialist confirms resin is the right method for your ground. It isn't right for every case.

2. One-day injection

Small drill points, controlled injection, real-time laser monitoring of the lift.

3. Cure and sign-off

Resin reaches structural strength in minutes. Building control sign-off included where required.

Will Resin Injection work for my home?

This is right for you if…

✓ Shrinkable clay shrinking back from the footings (most south east London cases)
✓ Loose made ground compacting under the slab
✓ Projects where you can't afford the disruption of traditional underpinning

This isn't the answer if…

× Footings that are themselves cracked or undersized (these need underpinning)
× Properties on solid chalk with no soil-driven movement

What it will cost and how long it takes

Cost

Domestic resin projects in the area typically cost £3,500 to £10,000, often a third of the price of equivalent underpinning. Insurance accepts geopolymer resin as a standard structural method.

Timeline

One to three days on site for most domestic jobs. The slab is ready to take load within an hour of the final injection.

What you actually get

Days, not weeks

Most projects finish inside a working week.

Garden and drive stay intact

No excavation. No skip licences. No piles of soil.

Set in minutes

Resin reaches structural strength within minutes of injection.

A fraction of underpinning cost

Often well under half the price for the right cases.

Will my insurance pay for it?

Major UK insurers accept geopolymer resin as a structural repair method when installed by an accredited specialist. The specialist supplies the report your claims handler needs, and the quote maps directly to your cover.

Resin Injection FAQs

For most domestic situations, yes. Cured resin reaches a compressive strength comparable to concrete and stabilises the load-bearing soil column under the footing.
