Adding Life to Concrete – How MARKHAM applied hydrogel waterproofing systems to multiple new concrete structures at Bamford Water Treatment Works in Derbyshire.
OBJECTIVE
As part of a significant upgrade and extension to the facilities at Bamford Water Treatment Works, MARKHAM were tasked with providing a waterproofing system for the new concrete Kiosk Slabs, a Pumping Station Chamber, Chemical Bunds and Delivery Areas, Contact and Backwash Tanks at this site.
This was to enhance the durability and increase the lifespan of these structures by waterproofing the concrete and, probably most importantly, protect the concrete against chemical attack in areas / structures that would come in contact with chemicals during the operation of the site.
SOLUTION
The MARKHAM system put forward to achieve these goals was the spray application of AQURON 2000. This retro spray application provides a waterproofing solution that penetrates up to 150mm into the concrete, replacing the more traditional epoxy coating systems that are often used in these situations.
RESULTS
As a DWI Reg 21 approved product, suitable for use in locations used for the storage of potable water, AQURON 2000 was a very rapid and cost-effective solution for waterproofing the concrete structures at this water treatment works.
It not only removed a significant proportion of the cost element of the materials for an epoxy coating solution, it also reduced the labour time / cost requirement for the main contractor, assisting them to keep ahead of their construction program.
The fact that AQURON 2000 can be applied to damp concrete and in relatively poor weather conditions, was a significant advantage over the application conditions required for an epoxy coating process, especially given the geographical location of the site and the requirement to carry out these works during the winter months when the demand on the Bamford Water Treatment Works is at its lowest.
With this depth of penetration, the AQURON 2000 is present within the matrix of the concrete for the lifespan of the concrete, making it a maintenance free solution that won’t require any further applications.

Project Details – Bamford Water Treatment Works | |
Description | Protection of new concrete Kiosk Slabs, a Pumping Station Chamber, Chemical Bunds and Delivery Areas, Contact and Backwash Tanks. |
Area Treated | 1,530 m2. |
Age of Structure | New (2024 – 2025) |
Requirements | Waterproofing Chemical resistance Zero maintenance DWI Reg 31 compliant |
Operation Downtime / Interruptions | All walls columns and floors were treated in situ after construction was completed, meaning that there was no interruption to the construction phases of the project. The construction program time was in fact reduced by the removal of the time that would have been taken in preparing for and installing epoxy coatings. |
Application Method | High Pressure Airless Spray Pumps – walls & columns Medium Pressure Boom Sprayer – floor slabs |
Proposed Further Works | No further works required. |
OHS Requirements | AQURON is nil VOC. Minimal PPE required. AQURON is DWI Reg 31 Approved |
