Scope of works
AQL carried out active water stopping methods and a restoration to inlet chamber, including: Crack Injection- 1300 linear metres of cracks were injected to stop any water ingress/egress. Holes were drilled every 200mm, injecting nipples installed and resin pumped into cracks. Protecting Cracks- After the injection was completed, all cracks were filled and a heat-resistant coating was applied to protect the concrete Pipe Penetrations- Crack injection was also completed around all pipe penetrations to stop any water egress through these voids. Screed- The floor of the inlet chamber was scabbled to create an optimal surface to apply the screed. The floor was then primed and a level 60mm screed was installed. Heat-Resistant Coating- A heat resistant lining was then applied to the inlet chamber to protect the new screed from the hot water entering.
