A complete, controlled process

From the first enquiry to a verified handover, every stage is planned, measured and delivered by one experienced team.

From enquiry to handover

Ten clear steps. One accountable team.

Every project starts with the ground. We understand what is there, determine how it can be improved and turn weak or unsuitable material into something the next stage of construction can rely on.

JJMac earthworks and stabilisation plant on site

The enquiry arrives

A client sends us the project information, drawings and Site Investigation. We establish what the development needs and where stabilisation could provide the greatest value.

Enquiry • Drawings • Programme

Site review for a JJMac soil stabilisation project

We understand the ground

Our team reviews soil type, moisture, CBR, groundwater, sulphates and required performance. Where necessary, samples are tested to confirm how the material will respond to treatment.

Site Investigation • Testing • Ground Conditions

JJMac stabilisation machine treating soil

We design the solution

The treatment depth, binder type and target performance are selected for each area. We also look for opportunities to reduce excavation, muck-away and imported aggregates.

Design • Value Engineering • Build-up

JJMac construction plant working across a prepared site

The proposal becomes a plan

We prepare the methodology, quotation and programme, clearly setting out what will be treated and how. Once agreed, the project is handed from estimating to the operational team.

Proposal • Agreement • Pre-start

Ground preparation for soil stabilisation

The ground is prepared

On site, treatment areas and levels are confirmed before material is placed in suitable layers. Wet or difficult soils can be conditioned before the final stabilisation process begins.

Preparation • Levels • Moisture Conditioning

Binder spreading equipment on a stabilisation project

Binder is spread accurately

The specified lime, cement or blended binder is applied evenly at the required rate. Quantities, delivery records and treated areas form part of the project quality record.

Lime • Cement • Controlled Application

JJMac stabilisation and compaction plant

Mix, compact and trim

The stabiliser blends the binder through the full treatment depth before rollers compact the layer. The surface is then trimmed to the required levels, falls and tolerances.

Mixing • Compaction • GPS Grading

Completed JJMac stabilised construction platform

We prove the performance

Testing verifies that the treated ground meets the project specification. Any local weakness is investigated, remediated and retested before the area is released.

CBR • Plate Load • Density • QA

Survey and GPS control used to record completed works

Everything is recorded

Final levels, treatment areas, test locations, binder records and photographs are brought together into the project QA package.

As-built • Test Results • Traceability

Finished stabilised platform ready for construction

Ready for handover

The finished platform and supporting documentation are formally handed to the client. The result is a verified construction surface ready for the next phase of the development.
