Life extension of concrete roads using geopolymer resin injection treatment

This report is concerned with the eastbound section of the carriageway on the M54. An investigation reported that the unreinforced concrete slabs in lane 1 had undergone settlement and an average uplift of 10mm was required to bring the traffic running surface back to level with adjacent slabs. Geobear’s geopolymer resin injection method was the chosen solution to repair the asset.

The use of expansive geopolymers to mitigate floor slab settlement

This paper provides an overview about geopolymers that can provide cost-effective solutions to lift and stabilise heavily loaded slabs suffering from excessive settlement. Within the paper, a detailed case study for a commercial warehouse with a failing concrete slab was examined to illustrate how geopolymer injections have effectively stabilised the slab without affecting the operations.

The use of expansive geopolymer injections to stabilise railway formation

The aim of this paper is to better inform the railway industry about the benefits and applications of geopolymer injections technology to treat formation problems. The paper will also explore a case study from an existing UK site where geopolymer injections have been used successfully on the railways to stabilise a piece of slab track that was moving, which had resulted in linespeed restrictions.

Rail Carbon Study

Carbon Footprint Ltd recently certified a report that found using a Geobear approach to asset maintenance in the rail sector could lead to a 75% reduction in carbon emissions. The report identified a railway level crossing with stabilisation issues and compared the carbon emissions of a complete reconstruction to Geobear’s asset maintenance solution.

Highways Carbon Study

This report is a comparison of the standard Geobear geopolymer injection service vs traditional highway concrete bay replacement. The Geobear Geopolymer Injection service produces less emissions than the traditional method. 5 Geobear treatments result in the avoidance of 62.43% of the modelled traditional method’s emissions.

Carbon Study - Residential

This report provides a comparison of the standard Geobear Geopolymer Injection service vs a traditional Piled Raft solution. The carbon footprint of the Geobear Geopolymer Injection service emits 53% less carbon compared to the traditional method. The reports are verified by Carbon Footprint Ltd and demonstrate that Geobear solutions emit less carbon.
