Remediology is a trading style of Ardula aimed at building on the company's growing reputation, and managing director's vast experience, in dealing with contaminated land.  By forming strategic partnerships, the Ardula Group will be able to offer complete single source solutions to managing and value engineering contaminated land destined for use in construction and development.  From cost planning, to intrusive investigation, commercially sensitive interpretation, risk profiling, and practical implementation, the company aims to offer a cradle to grave solution based on value engineering within best fit environmental regulation.

Early client engagement will allow remediation, recovery, and re-use strategies to be developed prior to the construction phase.

As each project will be effectively bespoke, MD Ricky Hemmings will provide early stage guidance and advice on the best long term commercial approach.  A call to discuss will be the first step in identifying each scheme's unique requirements.

Within the Ardula Remediology framework we aim to offer the following 

  • Initial site evaluation and risk profile
  • Desk top and intrusive site investigations, including targeted on site sampling in line with the development requirements
  • Interpretive reporting and recommendations based on value engineering and commercially beneficial options
  • Piling solutions in collaboration with our strategic partner
  • Topographical surveys and cut/fill earthworks modelling
  • Deployment of mobile treatment permits, and subsequent implementation
  • Crushing, screening, and processing of waste to achieve end of waste solutions and manufacture recovered aggregates and soils
  • Dust, noise and air quality management in support of our on site activities
  • Preparation, submission, implentation and management of Material Management Plans under the Definition of Waste Code of Practice
  • Construction of development platforms and pile mats
  • Best practice environmental solutions to comply with regulatory requirements
  • All activities managed in accordance with Environment Agency Land Contamination Risk Management Guidance issued June 2019
  • Recovery beneficial re-use of waste using our tipper fleet, to provide a cradle to grave single source solution

In July 2019, CL:AIRE and the Environment Agency issued a formal reminder to all those involved in producing, transporting, recovering, re-using, and disposal of construction and demolition waste, that significant tax penalties apply to the illegal deposit. 

The reminder communication can be found here, and serves not only to firmly outline the potential risks, but also underlines need for good advice and compliant solutions.  The Ardula cradle to grave single source option provides waste producers and stakeholder with a clear risk free path from excavation to deposition within a single organisational framework

Residential development in Kent

This development in Mid Kent had a site investigation which highlighted the chemical properties of the subgrade to be excavated, which in turn determined the proposed offsite disposal requirements.

At the suggestion of Ardula, a number of large trial pits were excavated, revealing a soil substrate with a high granular content. A simple screening process recovered over 30% of material having a PSD in excess of 10mm, which was able to be re-used on site. The process and re-use was carried under the appropriate environmental management, validated by the client's environmental consultant. The surplus soils underwent further in situ sampling before being removed for off site recovery or restoration use.


Ardula supplied all plant, labour, haulage, and supporting written methodology to provide a simple but effective solution.


IMPORT OF MATERIAL UNDER DoWCoP

This aerial image shows large scale earthworks for a residential development in East Sussex. Over 20,000 m3 of fill has been imported, and further treatment was carried out on site using Mobile Treatment Permitting to ensure that the material not only complied with the import specification, but was also able to meet the geotechnical design requirements, given that the development took place on a sloping landform


Case Study - Large residential basement construction in central London

The picture below shows a site in Kensington, West London.  The remit of Ricky Hemmings on this project was to risk profile the ground contamination at tender stage, and, post award, but prior to commencement, develop and implement a remediation strategy.  Innovative subterrain volumetric analysis gave robust projections of the percentage of contaminated soil within the overall 60,000m3.  Deployment of Mobile Treatment Permits prior to starting on site allowed made ground to be treated by initially screening as soils were excavated.  With a projected 15,000m3 of made ground, and a 40 percent recovery of hard material (from within the made ground) for on site crushing, the potential contaminated soil fraction was reduced considerably.  Further on site sampling, post treatment, clearly identified the contaminants and the disposal, recovery, and benefical re-use options.
