PROJECT
The top deck of the car park has a waterproof decking system laid which isn’t working and water is getting underneath the decking then leaking through the cracks in the slab. This leaking water when dripping onto cars parked below can cause damage to the paintwork. The requirement is to stop this happening.
Car park - Bluewater
THE CHALLENGE
The requirement is to stop the water coming through the structure, this can be done by either replacing the top deck waterproofing system (very expensive) or by sealing the cracks to stop the water coming through the concrete.
Quick Facts
- Normet utilized TamAcryl 2000 and TamRez 310EU to solved the leaking issue.
- To inject the cracks with TamAcryl 2000 to stop water being able to leak through.
- The crack is first sealed with TamRez 310EU (to hold the resin in while it cures)
- The TamRez 310EU are removed and the drill holes filled.
THE SOLUTION
To inject the cracks with TamAcryl 2000 to stop water being able to leak through. As well as stopping the water this will also provide protection to the steel reinforcement in the concrete, stopping it corroding.
The crack is first sealed with TamRez 310EU (to hold the resin in while it cures), the crack is then injected with TamAcryl 2000 via 13mm x 110mm metal packers. The following day the packers and TamRez 310EU are removed and the drill holes filled.

Project Outcome
The TamAcryl 2000 is a very low viscosity resin and flowed well and successfully sealed the crack. Potentially the injection holes spacing could be increased due to the flowability of the material, which would result in reducing the amount of drilling required. The below photo is taken after a weekend of rain showing the success of the injection process.
