Seawater had penetrated the structure completely, with water forming within the small air pockets found throughout the structure. The internal walls were also rotting and were continuously wet throughout the winter months. After trials were conducted with several products, it was found that the only suitable solution was Chemco.

Adding a single file download link (as above)

Go to WP File Download in the left-hand admin menu > in the folder column click on “Case Study PDFs” > this will list your case study folders, in this example I’ll click on “Offshore” to view the files within it > then click on the file you want > once it’s retrieved that file’s info the right-hand column will update with that files properties – scroll down to the bottom of that column to see a field called “Single File Shortcode” – simply click on the “copy” button > now go to wherever you want to place the download link and paste this into plain text (within an appropriately sized column) and you’ll have your download link.

IMPORTANT – Do not change the name or location of any of the files within WP File Download otherwise the file will not update when we come to upload new copies of these files (on mass) within the external Dropbox account (unless you also plan to update that file within your in-house system).  Instead, update the title that shows in the above button by editing the “name” field within the shortcode (which does leaves the actual file alone).

Alternatively, if you want to link to a download within text (like thisor see the summary block at the top of the page) or from a button element (below) then you’ll need to do the above to find your file > scroll down the right-hand file properties column and just above “Single File Shortcode” you’ll see a field called “File Direct Link” > click “copy” and then paste that into the link field of your text or button link.


The lighthouse had to be encapsulated due to the harsh weather conditions found next to the coast and to stop further water ingress. The encapsulation also ensured that no debris from the surface preparation procedures would contaminate the sea.

And something else to say

This image isn’t the same size as the others – is that a problem?


All external cracks were opened up; resulting in the release of water held within the walls. Abrasive blasting was utilised as the surface preparation method.

One primer coat of Damp-creteTM RH 800 was applied over the entire concrete structure. All holes and cracks were then filled with Chem-concreteTM RI 800CRS.

One coat of solvent-free, wet tolerant epoxy Epo-chemTM RA 500M was then applied as an impermeable barrier before one high gloss topcoat of Fast-guardTM RN 500TC was applied.

The project was completed within the given timeframe and to the complete satisfaction of all parties involved.

In recent years the high cost and environmental impact of grit blasting has forced the industry to look at alternative surface preparation methods. Chemco’s innovative technology enables surfaces to be prepared via mechanical means or high pressure wet jetting.
