Resin injection in Hampshire

Resin injection for foundations in Hampshire

A crack near the floor line or a door that sticks can point to movement below. Resin injection foundations offer one way to address this without digging up the garden. Describe what you have noticed and a specialist firm will review it.

Repair methods

How geopolymer foundation repair works in Hampshire

brown brick wall
Resin injection under footings
A two-part geopolymer resin is pumped through small holes drilled beside the footing. It expands in the voids below, compacting loose soil and filling gaps to halt further settlement.
Resin injection under floor slab
Where a concrete floor has dropped or cracked, resin is injected directly beneath the slab. The expansion lifts the concrete back toward its original level and fills empty space.
Soil injection subsidence repair
On sites where the bearing capacity of the ground has weakened, soil injection forces resin deeper into the strata. This densifies soft layers so they carry the load again.
Underpinning with mass concrete
When resin cannot reach stable ground, a specialist excavates sections below the existing footing and pours concrete to a firmer stratum. Read more about underpinning in Hampshire.

When resin suits

Conditions where non disruptive foundation stabilisation fits

Resin suits granular soils such as the sands and gravels found around Farnborough and Totton. It compacts loose particles and fills voids where the ground has washed away or settled over time.

Clay shrinkage during dry summers causes movement across Fareham and Waterlooville. If the clay is still active, resin alone may not hold. A specialist assesses whether the moisture cycle has stabilised first.

Made ground along the coast at Gosport or Hythe often contains old fill that compresses unevenly. Resin can consolidate shallow voids, but deep instability might require screw piling instead.

Tree roots drawing moisture from clay cause seasonal movement. Removing the tree can trigger heave. Resin addresses the symptom but a specialist must rule out ongoing root activity before recommending it.

Typical costs for foundation resin repair work

The price of stabilising a home depends on how much resin the ground absorbs, the depth of treatment and access around the building. Loose gravel takes more material than firm clay, and working inside a house adds preparation time.

  • Single room slab lift

    £1,500 to £3,000

    Floor area, void depth and access for drilling equipment inside the room.

  • Wall footing stabilisation

    £3,000 to £7,000

    Length of wall treated, soil density and number of injection points needed.

  • Full perimeter treatment

    £6,000 to £15,000

    Property size, ground conditions and whether internal floors also need lifting.

  • Mass concrete underpinning

    £10,000 to £30,000

    Depth to firm stratum, length of wall and spoil removal logistics.

These figures indicate what work of this type typically costs. Nothing here is a quotation. Only a site inspection settles a figure for one home.

What happens after you send an enquiry

The details you provide go to a specialist firm covering your part of Hampshire. They read the description, check the location against local ground conditions and arrange a survey if the problem fits their work.

  1. The same day it is sent

    Your description reaches a specialist firm that handles resin injection and foundation repair in your area of Hampshire.

  2. Usually within a few days

    The firm reviews the details and contacts you to ask follow-up questions or to arrange a visit to the house.

  3. After the site visit

    A report sets out what the ground is doing and whether resin injection or another method is the right approach.

Questions homeowners ask about resin injection

These are the things people want to know before agreeing to a survey or a repair method.

Stabilising foundations with resin
The resin expands in voids and compacts surrounding soil. Once cured, it forms a solid mass that spreads the load of the wall or slab across a wider area of ground.
When underpinning is recommended
If the weak soil extends beyond the reach of the resin, or the structure needs support transferred to a deeper stratum, traditional mass concrete underpinning becomes necessary.
Tree roots drying clay soil
Resin can fill the gaps left by shrinkage, but if the roots are still extracting moisture the clay will keep moving. The tree issue must be resolved first.
Duration and staying in the home
Most jobs take one or two days. Because the work uses small drill holes rather than trenches, occupants usually remain in the house throughout.
Planning and building control
Resin injection generally falls outside planning requirements. Building control involvement depends on the scale of the movement and whether the insurer requires formal sign-off.
Insurer acceptance of resin repair
Insurers generally accept resin injection when a structural engineer specifies it and the paperwork supports the claim. The specialist firm handling the work supplies the reports your insurer needs to assess and approve the repair.

Areas covered for resin injection in Hampshire
