Waterseal seal the new Kincardine Bridge.

 
Waterseal in conjunction with it's sister company JB Concrete Protection recently completed the bridge deck waterproofing, surface impregnation and joint sealant works on the new Kincardine bridge.
 
Over 24,000m² of main deck and other structures were waterproofed using Stirling Lloyd's Eliminator system with ouputs of 1,000m² per day during the summer!
 
Surface impregnation of the main bridge and surrounding strucutres were carried out using Repel WB40 one coat system with over 34,000m² being protected.

Repel passes all tests - Again

The Highways Agency has recently commissioned the Transport Research Laboratory to review the performance of impregnants currently available for use which meet the requirements of BD43/03. The purpose of this research is to gain improved knowledge about the performance of impregnants and to judge whether current standards are sufficiently robust to discriminate between acceptable and non-acceptable impregnants.

Repel WB40 met all the test requirements. The new Highways Agency report is expected to show that crystal growth pore blockers ( such as Pavix ) did not perform very well at reducing chloride ingress.

This in turn is expected to influence the updated requirements of BD43 due out early next year…. WATCH THIS SPACE!

Waterseal transform two exposed roof deck parking levels at the Brent Cross Shopping Centre, London.
 
Tasked with overlaying 20,000m² of failing mastic asphalt, Waterseal selected a technically advanced, multi layered, lightweight waterproofing system to provide their client with their desired result.
 
As an approved applicator of a range of deck coating systems, a system incorporating a spray applied membrane was selected. This elastomeric membrane provides guaranteed waterproof protection to the structure as it has the ability to bridge live cracks and can accommodate movement within the substrate being overlaid.
 
Being pigmented, the wear courses within this system allowed colour differentiation within parking bays, running aisles and pedestrian walkways which has resulted in a more user-friendly parking facility, with the appearance of these previously bland car parks being completely transformed.
 
Prior to carrying out the aforementioned deck coating works, Waterseal undertook considerable amounts of surface preparation work to ensure a suitable surface was provided to overlay. These works included raking out all of the waste accumulated in the cracks and fissures within the failing mastic asphalt and regulating all of the indentations caused by the mastic asphalt displacing during periods of warm weather when vehicles were parked on it.
